HOSES Following are some of the common types of hoses PTFE HOSES PTFE hoses have a very good chemical resistance to most fluids, resist to high temperatures, have non-sticking and very low-friction characteristics, have almost no aging, and can be constructed to achieve very good flexibility and pressure resistance. Characteristics of PTFE hoses •
Chemically resistant - PTFE hoses are extremely resistant to most conveyed fluids. The only reactants are extreme oxidizers and reducing agents (elementary sodium, fluorine, chlorine trifluoride and related compounds), and alkali metals (potassium and lithium).
•
Temperature resistant - PTFE has a very extensive working temperature range. PTFE hoses generally cover the range of -50°C to +200°C, which includes most industrial applications.
•
Non-sticking - PTFE offers no adherence to other substances. Even in alternate use of fluids, contamination risk of the fluid is very limited.
•
Low-friction - PTFE hoses also assure optimum flow rates of all conveyed fluids and very limited pressure losses in the fluid lines.
•
Non-toxic - PTFE is odor-, taste- and color-less and transmits none of these to the conveyed fluids. PTFE is a FDA approved material for food contact and PTFE hoses are excellent for the food industry.
•
Un-inflammable - PTFE does not have any flame propagation
•
Durable - Due to its chemically inert characteristic, PTFE hoses are virtually ageless. PTFE hoses have limitless shelf life. Weather resistance is also virtually limitless.
Applications •
Due to its overall excellent chemical resistance, PTFE hoses are used in a very wide variety of industrial applications for conveyance of hot and cold gases, steam, water, synthetic and petroleum-base hydraulic fluids, as well as corrosive chemicals.
•
Due to its non-contaminant and non-contaminable characteristics, PTFE hoses are used in a wide variety of medical and laboratory apparatus, cosmetics, food industry, automotive and aeronautics industries.

and high temperature gases and liquids at low pressure, electrical isolation applications FLEXIBLE METAL HOSES Metal hose is used when temperature extremes, corrosive media, or permeation preclude the use of rubber, PTFE, or plastic hose. Typical applications are found in steel making, chemical processing, paper manufacturing, petroleum refining, and in numerous other industrial applications. Where rigid connections are impractical, flexible metal hose provides non-rigid connections for conveying liquids, gases and semi-solids.
Following are the benefits and advantages of flexible metal hoses High physical strength combined with light weight. Suitable for wide temperature range [-2700 C to + 7000C] Good corrosion resistance. Resistance to fire, moisture, abrasion and penetration. Absorbs vibration and noise from pumps, compressors, engines etc Compensates for thermal expansion or contraction of piping. Connects misaligned rigid piping. A flexible and quick option for right piping in difficult locations. • STRIPWOUND METAL HOSES • • • • • • • • •
STRIP WOUND HOSES are manufactured by helically winding a pre-formed strip around a mandrel of the required size. A packing of copper wire, rubber or yarn may be provided within the folds during the manufacturing process to obtain liquid tightness. Special winding processes ensure a low leakage rate and high flexibility.

• CORRUGATED HOSES The corrugated hose is manufactured from a cylindrical, thin walled tube formed from rolled strip and joined at the seam by butt welding. Impressed into this tube is a corrugated annular profile. Annular corrugated hose has several advantages over helical hose. It is not subject to damaging torsional stress due to longitudinal expansion resulting from pressure rises. When the corrugations are closely spaced, the hose is referred to as "standard pitch" hose. When the corrugations are more widely spaced, the hose is referred to as "open pitch" hose. The thickness of the metal strip, the height of the corrugations and the number of corrugations per foot all affect the performance characteristics of metal hose. Flexibility in corrugated hose is the result of the bending of the metal corrugations. Service life varies depending upon the severity of the flexing, the temperature, corrosive conditions, pressure and vibration to which the hose is subjected. is the result of the bending of the metal corrugations. Service life varies depending upon the severity of the flexing, the temperature, corrosive conditions, pressure and vibration to which the hose is subjected. Unless restrained, corrugated hose will elongate when subjected to increasing internal pressure. This restraint is provided by a braided covering, consisting of a tubular sheath of woven metal wires fitted tightly over the corrugated hose and secured at each end. Flexibility of the corrugated hose is not appreciably affected by this wire braid covering. In addition, the braid provides squirm support and dampens vibration. In higher pressure applications, the use of additional braid covers will provide additional working pressure. Unbraided hose is satisfactory for vacuum and low pressure applications. Corrugated hose is recommended for applications involving permanent bends, and in situations where flexing is predictable, that is, machine controlled. Also, whenever absolute leak prevention is essential, corrugated hose should be selected. Braiding materials can be : stainless steels, steels, bronze, inconel, monel etc. STAINLESS STEEL CORRUGATED HOSE Stainless steel hoses facilitate relative movement of the parts to be connected, adapt to thermal expansion, resist to high pressure and offer good corrosion resistance to a wide range of fluids. Braid provided on the inner tube plays an important role. When pressure is applied, unbraided corrugated hose tends to elongate axially. To restrain this an external layer of SS wire is provided on the hose. The braid is necessary to prevent elongation and to make the assembly pressure resistant. Some times two or even three layer of braiding are provided for high pressure applications. The braiding is highly flexible and follows the movement of the hose. The braiding is normally manufactured in SS 304 wire. SS 316 and SS 321
