Foreword T o the engineer responsible for the design and operation o f safe and efficient piping systems, t h i s "Datalog" i s presented w i t h the hope that i t w i l l f a c i l i t a t e the burdensome tasks peculiar to piping layout. Painstaking efforts have been made to assemble such standards, technical data, charts and recommendations as are necessary for him to cope w i t h the diverse problems i n Power P l a n t and Industrial Piping, many o f which, due to the trend toward higher pressures and temperatures, are o f a highly specialized nature. The "Datalog" divides i t s e l f into two sections, the f i r s t of which i s devoted almost entirely to dimensions and general notes w i t h reference to fabrication and shop practice. The Standards shown are those approved by recognized engineering groups such a s the American Standards Association, American Society for Testing and Materials, American Society of Mechanical Engineers, American Welding Society, P i p e Fabrication Institute and others. The data contained herein are those a s taken from the most recent issues of these Standards. The Technical Section, which begins on page 165, includes technical data, charts and recommendations, which, we be1ieve, conform with the most stringent engineering practice. A great part of t h i s information i s the result o f tests and investigations conducted by our own Research Department, supplemented by a background of successful performance i n industry. The knowledge o f piping which we have gained i n over a half-century has not been confined to design and fabrication alone, but includes a wide f i e l d experience i n erecting, testing and placing in operation, p i p i n g systems for every power plant and industrial need. The publishing of t h i s book has been actuated by our desire to convey to the Engineering Fraternity and t o the buyers and users of piping, the knowledge gained by extensive research and operation throughout that period.

W a l l Thickness Calculations And Working Pressures For Pipe

(' j

Due ta the fact that metals i n general lose strength a s service temperatures increase, the ASME Boiler and Pressure Vessel Code, Section I, Power Boilers, and the ANSl Code for Pressure Piping, 831.1, Power Piping, have estobjished safe working stresses for mast materials used, based on the service temperature. Allowable stress values for the various grades of pipe most cammonly used i n Power P i p i n g are shown on pages 18 through 21, c l a s s i f i e d under the applicable ASTM specification. These tobulotions cover ollowable stresses (SE) for bath the Boiler Code, Section I and 831.1 Pawer Piping Code a t temperatures ranging from -20°F t o 1500DF, w i t h the 1250 t o 1500°F range applying to the Boiler Code only. I t should be noted also that the Bailer Code indicates allowable stresses for some of the materials ot temperatures higher than those allowed i n the Power Piping Code, 831.1, w h i c h are tabulated here. Similarly, the Code for Pressure P i p i n g a l l o w s higher warking stresses for Petroleum Refinery Piping i n ANSl 831.3, Gas Transmission and D i s t r i b u t i o n Piping i n ANSl 831.8, Industrial Gas and Air Piping, etc. For allowable stresses for these code iurisdictions, the designer i s referred t a the applicable code. The f o l l o w i n g formulae shall be used i n determining minimum pipe w a l l thi,cknesses required for known pressures a t given temperatures, or for c a l c u l a t i n g maximum allowable working pressures for known miiiimum w a l l thicknesses at given temperatures.

Ratings for Carbon and Ferritic

Alloy Steel Flanges, Flanged Fittings, Flanged and Butt-Weld End Valves ASA Standard 816.5

These ratings remain constant throughout a l l sizes of any one pressure class. However, reference should be mode to codes of regulatory agencies t o determine the size, pressure and temperature limitations imposed upon the use of threaded, socket-welding and slip-on welding type flanges. A l l pressures are in pounds per square inch Temperatures and pressures l i s t e d are maximum internal fluid temperatures and pressures. Hydrostatic tests shall be made with water at a temperature not to exceed 125 F or as required by applicable codes. Test pressures ore manufacturers' shell tests applicable t o valves and fittings. Flanges may be tested after attachment to piping or vessel i n accordance with applicable code requirements, i n which case the test pressures may be higher than those as shown i n tables. I n such cases consideration should be given to gasket design to avoid excessive deformation of the flange. Where welded construction i s to be used, considera-

tion should be given to the possibility of graphite formation i n the following ,steels: Carbon steel above about 800 F, Carbon-Molybdenum steel above about 875 F, and Chrome-Molybdenum steel (with Chromium content under 0.6%) above about 975 F. Consideration should also be given to the possibility of excessive oxidation (scaling) on the following steels: 1 Cr K Mo, 1% Cr 5 Mo, 2 Cr 5 Mo, 2K Cr 1 Mo, and 3 Cr 1 Mo above 1050 F, and 5 Cr 5 Mo above 1100 F.

Ratings are identical for a l l types of flange facings including ring joint. I n using these ratings the designer I s responsible for selecting gasket materials adequate for the service conditions and the obility of the gasket to resist injurious crushing. Products used within the iurisdiction of the ASME Boiler and Pressure Vessel Code and the ASA Code for Pressure Piping are subject to the maximum temperature and stress limitations upon the material and piping stated therein.

ASME B31.3-1996 Edition

302.3.6 Limits of Calculated Stresses due to Occasional Loads (a) Operation. The sum of the longitudinal stresses due to pressure, weight, and other sustained loadings SL and of the stresses produced by occasional loads, such as wind or earthquake, may be as much as 1.33 times the basic allowable stress given in Appendix A. For castings, the basic allowable stress shall be multiplied by thecasting quality factor E,. Where the allowable stress value exceeds two-thirds of yield strength at temperature, the allowable stress value must be reduced as specified in para. 302.3.2(e). Wind and earthquake forces need not be considered as acting concurrently. (b) Test. Stresses due to test conditions are not subject to the limitations in para. 302.3. It is not necessary to consider other occasional loads, such as wind and earthquake, as occurring concurrently with test loads. 302.4

Allowances

In determining the minimum required thickness of a piping component, allowances shall be included for corrosion, erosion, and thread depth or groove depth. See definition for c in para. 304.1.l(b). 302.4.1 Mechanical Strength. When necessary, the wall thickness shall be increased to prevent overstress, damage, collapse, or buckling due to superimposed loads from supports, ice formation, backfill, or other causes. Where increasing the thickness would excessively increase local stresses or the risk of brittle fracture, or is otherwise impracticable, the required strength may be obtained through additional supports, braces, or other means without an increased wall thickness. Particular consideration should be given to the mechanical strength of small pipe connections to piping or equipment.

PART 2 PRESSURE DESIGN OF PIPING COMPONENTS 303

GENERAL

Components manufactured in accordance with standards listed in Table 326.1 shall be considered suitable for use at pressuretemperature ratings in accordance with para. 302.2.1. The rules in para. 304 are intended for pressure design of components not covered in Table 326.1, but may be used for a special or more rigorous design of such components. Designs shall be checked

302.3.6-304.1.1

for adequacy of mechanical strength under applicable loadings enumerated in para. 301.

Straight Pipe

304.1.1 General (a) The required thickness of straight sections of pipe shall be determined in accordance with Eq. (2):

The minimum thickness T for the pipe selected, considering manufacturer's minus tolerance, shall be not less than I,. (b) The following nomenclature is used in the equations for pressure design of straight pipe. t , = minimum required thickness, including mechanical, corrosion, and erosion allowances t = pressure design thickness, as calculated in accordance with para. 304.1.2 for internal pressure or as determined in accordance with para. 304.1.3 for external pressure c = the sum of the mechanical allowances (thread or groove depth) plus corrosion and erosion allowances. For threaded components, the nominal thread depth (dimension h of ASME B1.20.1, or equivalent) shall apply. For machined surfaces or grooves where the tolerance is not specified, the tolerance shall be assumed to be 0.5 mm (0.02 in.) in addition to the specified depth of the cut. T = pipe wall thickness (measured or minimum per purchase specification) d = inside diameter of pipe. For pressure design calculation, the inside diameter of the pipe is the maximum value allowable under the purchase specification. P = internal design gage pressure D = outside diameter of pipe as listed in tables of standards or specifications or as measured E = quality factor from Table A-IA o r A-1B S = stress value for material from Table A-1 Y = coefficient from Table 304.1.1, valid for t < D/6 and for materials shown.

(a) Except as provided in (b) below, the requirements in paras. 304.3.2 through 304.3.4 are applicable to branch connections made in accordance with the following methods: (I) fittings (tees, extruded outlets, laterals, crosses); (2) welding outlet fittings, including cast or forged nozzles, couplings not over DN 80 (NPS 3), and adapters or similar items having buttwelding, socketwelding, threaded, or flanged ends for attachment of the branch pipe, such fittings being attached to the run pipe by welding; (3) welding the branch pipe directly to the run pipe, with or without added reinforcement, as covered in para. 328.5.4. (b) The rules in paras. 304.3.2 through 304.3.4 are minimum requirements, valid only for branch connections in which (using the nomenclature of Fig. 304.3.3): (I) the run pipe diameter-to-thickness ratio (Dh/ Th) is less than 100 and the branch-to-run diameter ratio (Db/Dh) is not greater than 1.0; (2) for run pipe with (Dh/Th) 2 100, the branch diameter Db is less than one-half the run diameter Dh; (3) angle fl is at least 45 deg; ,I (4) the axis of the branch intersects the axis of the run. (c) Where the provisions of (a) and @) above are not met, pressure design shall be qualified as required by para. 304.7.2. (d)Other design considerations relating to branch connections are stated in para. 304.3.5. I

304.3.2 Strength of Branch Connections. A pipe having a branch connection is weakened by the opening that must be made in it and, unless the wall thickness of the pipe is sufficiently in excess of that required to sustain the pressure, it is necessary to provide added reinforce-

304.3.2-304.3.3

ASME B31.3-1996 Edition

ment. The amount of reinforcement required to sustain the pressure shall be determined in accordance with para. 304.3.3 or 304.3.4. There are. however, certain branch connections which have adequate pressure strength or reinforcement as constructed. It may be assumed without calculation that a branch connection has adequate strength to sustain the internal and external pressure which will be applied to it if: (a) the branch connection utilizes a fitting (a tee, lateral, or cross) in accordance with para. 303; (b) the branch connection is made by welding a threaded or socket welding coupling or half coupling directly to the run in accordance with para. 328.5.4, provided the size of the branch does not exceed DN 50 (NPS 2) nor one-fourth the nominal size of the run. The minimum wall thickness of the coupling anywhere in the reinforcement zone (if threads are in the zone, wall thickness is measured from root of thread to minimum outside diameter) shall be not less than that of the unthreaded branch pipe. In no case shall a coupling or half coupling have a rating less than Class 2000 per ASME B16.11. (c) the branch connection is made by welding an integrally reinforced branch connection fitting to the run pipe, provided the fitting is made from materials listed in Table A-1 and provided it has been demonstrated by full-scale internal pressure tests or other means described in para. 304.7.2 that the branch fitting is at least as strong as the run or branch pipes. 304.3.3 Reinforcement of Welded Branch Connections. Added reinforcement is required to meet the criteria in (b) and (c) below when it is not inherent in the components of the branch connection. Sample problems illustrating the calculations for branch reinforcement are shown in Appendix H. (a) Nomenclature. The nomenclature below is used in the pressure design of branch connections. It is illustrated in Fig. 304.3.3, which does not indicate details for construction or welding. Some of the terms defined in Appendix J are subject to further definitions or variations, as follows: b = subscript referring to branch d l = effective length removed from pipe at branch d 2 = "half width" of reinforcement zone = d l or (Tb - c) (Th - C) d1/2, whichever is greater, but in any case not more than Dh h = subscript referring to run or header L4 = height of reinforcement zone outside of run pipe = 2.5(Th - c ) or 2.5(Tb - c) + T,. whichever is less

T, = branch pipe thickness (measured or minimum per purchase specification) except for integrally reinforced branch connections. For such connections the value of Tb for use in calculating L4, d z , and A3, is the thickness of the reinforcing barrel (minimum per purchase specification) provided that the barrel thickness is uniform (see Fig. K328.5.4) and extends at least to the L, limit (see Fig. 304.3.3). T, = minimum thickness of reinforcing ring or saddle made from pipe. (Use nominal thickness if made from plate.) = 0, if there is no reinforcing ring or saddle t = pressure design thickness of pipe, according to the appropriate wall thickness equation or procedure in para. 304.1. For welded pipe, when the branch does not intersect the longitudinal weld of the run, the basic allowable stress S for the pipe may be used in determining th for the purpose of reinforcement calculation only. When the branch does intersect the longitudinal weld of the run, the product SE (of the stress value S and the appropriate weld joint quality factor E, from Table A-IB) for the run pipe shall be used in the calculation. The product SE of the branch shall be used in calculating t,. p = smaller angle between axes of branch and run (b) Required Reinforcement Area. The reinforcement area A, required for a branch connection under internal pressure is

For a branch connection under external pressure, area A is one-half the area required for internal pressure. (c) Available Area. The area available for reinforcement is defined as

(3) Area A4 is the area of other metal provided by welds and properly attached reinforcement. [See (f) below.] Weld areas shall be based on the minimum dimensions specified in para. 328.5.4, except that larger dimensions may be used if the welder has been specifically instructed to make the welds to those dimensions. (d) Reinforcement Zone. The reinforcement zone is a parallelogram whose length extends a distance of d , on each side of the center line of the branch pipe and whose width starts at the inside surface of the run pipe (in its corroded condition) and extends beyond the outside surface of the run pipe a perpendicular distance L , . (e) Multiple Branches. When two or more branch connections are so closely spaced that their reinforcement zones overlap, the distance between centers of the openings should be at least 11% times their average diameter, and the area of reinforcement between any two openings shall be not less than 50% of the total that both require. Each opening shall have adequate reinforcement in accordance with (b) and (c) above. No part of the metal cross section may apply to more than one opening or be evaluated more than once in any combined area. (Consult PFI Standard ES-7 for detailed recommendations on spacing of welded nozzles.) J( Added Reinforcement (I) Reinforcement added in the form of a ring or saddle as part of area A shall be of reasonably constant width. (2) Material used for reinforcement may differ from that of the run pipe provided it iscompatible with run and branch pipes with respect to weldability, heat treatment requirements, galvanic corrosion, thermal expansion, etc. (3) If the allowable stress for the reinforcement material is less than that for the run pipe, its calculated area must be reduced in the ratio of allowable stress values in determining its contribution to area A 4 . (4) No additional credit may be taken for a material having higher allowable stress value than the run pipe.

304.3.4 Reinforcement of Extruded Outlet Headers (a)The principles of reinforcement stated in para. 304.3.3 are essentially applicable to extruded outlet headers. An extruded outlet header is a length of pipe in which one or more outlets for branch connection have been formed by extrusion, using a die or dies to control the radii of the extrusion. The extruded outlet projects above the surface of the header a distance h , at least equal to theexternal radius of the outlet r , (i.e., h , 2 rx).

(b) The rules in para. 304.3.4 are minimum requirements, valid only within the limits of geometry shown in Fig. 304.3.4, and only where the axis of the outlet intersects and is perpendicular to the axis of the header. Where these requirements are not met, or where nonintegral material such as a ring, pad, or saddle has been added to the outlet, pressure design shall be qualified as required by para. 304.7.2. (c) Nomenclature. The nomenclature used herein is illustrated in Fig. 304.3.4. Note the use of subscript x signifying extruded. Refer to para. 304.3.3(a) for nomenclature not listed here. d, = the design inside diameter of the extruded outlet, measured at the level of the outside surface of the header. This dimension is taken after removal of all mechanical and corrosion allowances, and all thickness tolerances. hx = height of the extruded outlet. This must be equal to or greater than r, (except as shown in sketch (b) in Fig. 304.3.4). Lj = height of reinforcement zone = 0.7 T, = corroded finished thickness of extruded outlet, measured at a height equal to rx above the outside surface of the header dZ = half width of reinforcement zone (equal to dx ) rx = radius of curvature of external contoured portion of outlet, measured in the plane containing the axes of the header and branch. (d) Limitations on Radius r,. The external contour radius rx is subject to the following limitations. (I) minimum r , : the lesser of 0.05Db or 38 mm (1.50 in.); (2) maximum r , shall not exceed: (a)for D , < D N 200 (NPS 8), 32 mm (1.25 in.); (b) for D b 2 D N 200, O.lDb

+ 13 mm (0.50 in.);

(3) for an external contour with multiple radii, the requirements of (1) and (2) above apply, considering the best-fit radius over a 45 deg. arc as the maximum radius; (4) machining shall not be employed in order to meet the above requirements. (e) Required Reinforcement Area. The required area of reinforcement is defined by

The manufacturer shall establish the design pressure and temperature for each extruded outlet header and shall mark the header with this information, together with the symbol "B3 1.3" (indicating the applicable Code Section) and the manufacturer's name or trademark. 304.3.5 Additional Design Considerations. The requirements of paras. 304.3.1 through 304.3.4 are intended to ensure satisfactory performance of a branch connection subject only to pressure. The designer shall also consider the following. (a) In addition to pressure loadings, external forces and movements are applied to a branch connection by thermal expansion and contraction, dead and live loads, and movement of piping terminals and supports. Special consideration shall be given to the design of a branch connection to withstand these forces and movements. (b) Branch connections made by welding the branch pipe directly to the run pipe should be avoided under the following circumstances:

(I) when branch size approaches run size, particularly if pipe formed by more than 1.5% cold expansion, or expanded pipe of a material subject to work hardening, is used as the run pipe; (2) where repetitive stresses may be imposed on the connection by vibration, pulsating pressure, temperature cycling, etc. In such cases, it is recommended that the design be conservative and that consideration be given to the use of tee fittings or complete encirclement types of reinforcement. (c) Adequate flexibility shall be provided in a small line which branches from a large run, to accommodate thermal expansion and other movements of thillarger line (see para. 3 19.6). '(d)If ribs, gussets, or clamps are used to stiffen the branch connection, their areas cannot be counted as contributing to the reinforcement area determined in para. 3043.3(c) or33?4.3.4(f). However, ribs ,or gussets may be used for pressure:strengthening a branch connection in lieu of reinfdrbment covered in paras. 304.3.3 and 304.3.4 ifthe design is qualified . , as required by para. 304.7.2. (e) For branch connedtions whi meet the requirements, of para. 304.3.1(b), integral reinforcement, complete encirclement reinforcement, or other means of reinforcement should be considered. 304.3.6 Branch Connections Under External Pressure. Pressure design for a branch connection subjected to external pressure may be determined in accordance with para. 304.3.1, using the reinforcement area requirement stated in para. 304.3.3(b).
