VI DEMARRAGE DE L'INSTALLATION

VI STARTING THE INSTALLATION

Apres un stockalte prolonge du materiel, quelques fuites au presse garniture peuvent se produire . II est alors necessaire de proceder ä un nouveau serrage. Celui-ci doit etre modere et doit cesser des que 1'etancheite a ete obtenue. En effet, dans le cas de vannes motorisees, un ex-Ps de serrage peut entrainer, par suite de 1'augmentation df, couple, qu'il amene, un arrei: intempestif de la motorisation pour un declenchement du contact actionne par le limiteur de couple .

After a Jong storage of the equipment a leak can appear at the stuffrng box . lt is then necessary to increase the pressure an the packing rings by tightening the gland bolting. It is not recom mended to apply an exessive pressure but just enough to stop the leak . Exessive pressure an packings generating an increase in operating torque and in case of motor operated valve a premature stop of the engine can occur by the action of the torque swit ch .

Lors du branchement electrique des motorisations, Je couvercle du coffret doit etre enleve pendant le minimum de temps de maniere ä eviter l'introduction d'eau dans le carter . En outre, durant cette operation aucune intervention West ä faire au niveau des contacts de fin de course et du limiteur de couple, un reglage approprie ayant ete execute lors de la reception du materiel .

For the electric connection of motor operated %alve tlie cover of the junction box has to be removed for the shortest time to avoid water coming into the electric organs .

XI MAINTENANCE OF VALVES Valves will be subject to previsionnal and periodical maintenance . ne follo~ring ponts have to be checked - lubnfication of stem nut with mmeral grease

- Graissage des douilles de manoeuvre avec une graisse minerale classique,

- checking the oll or grease in the gear operators or in the electric motors .

- Verification des reserves d'huile ou de graisse des motonsations ou des rEklucteurs.

- tightness of stuffmg box, in rase of leak an altemate action an the gland boltmg will thigten the leak .

- Etancheite du presse-gamiture. En cas de non etancheite, proceder ä un nouveau ser e, par action altemee sur ]es tiges filetees de fixation de la bride de fouloir. Afin que le fonctionnement reste normal, il est bon que le fouloir ne descende pas ä I'interieur de son logement d'une valeur superieure ä 2 anneaux soit 12 ä 24 mm suivant les orifices . Si I'etancheite ne pouvait etre realisee aprbs une telle action, il faudrait alors ajouter une bague ou deux en veillant ä utiliser Je meme bourrage q,ue celui d'origine. Cette operation ne peut se faire qu'ä condition que 1'appareil soit ouvert ä fond de maniere ä obtenir un contact entre le cöne de tige et Ie cöne de bague de butee.

For good working conditions it is recommen ded that the gland does not go down in the stuffeng box more than two times the thickness of a packing ring (approx 12 to 24 mm depending an the sizes) . Iftightness cannot be achieved . alter such an action one or two packing rings of adequate size and material same as the original part, have to be added. This operation can only be perfomed when the valve is in fully open poskion in order to get a sealing contact between the stem cone and the back seat .

- Verification de la manoeuvre ouverture et fermeture En effet, certains appareils restent pendant tres longtemps, dans la meine position . 11 est alors souhaitable de realiser quelques manoeuvres ä vide de maniere ä eviter l'ankylose du materiel . - Etancheite du plan de Joint corps;-chapeaux et u niveau des brides de raccordement sur la tuyautene. Si cette etancheite n'etait plus obtenue 11 faudrait alors resserrer I'ensemble des tiges filetees de fixation et ce, de fa~on reguliere et symetrique . Si un changement de Joint s'avere necessaire il est bon, dans Je cas de joints metalliques ondules ou striees, de remonter ceux-ci hui1es . Voperation de serrage des tiges doit se faire de maniere symetrique . XII REPARATION DU MATERIEL DE ROBINETTERIE Bien qu'il sofft preferable d'en confier l'execution au cor -ucteur ou ä un reparateur specialise, certams travaux de reparation peuvent etre realises par Je Service Entretien des diverses societes . Dans cette hypothese, il est souhaitable qu'un stock de pieces de rechange de premiere urgence soient tenues en magasin. Celui-ci doit notamment comporter - Joints, gamitures, ressorts, boulonnerie, - Sieges, obturateurs, tiges de nranoeuvre et leur douille correspondante - Elements de rechange des comrnarrdes mecaniques electriques, pneumatiques ou hydrauliques

- checking the opening operation. Valves can stay, for a Jong period in the same position . lt is then recommended to do some operation of the valve in order to prevent the valve to stiffen. - check the tightness of the body bonnet Joint connection as well as the body/piping flange connection . Iftightness cannot be obtained all bolting will have to be re-tighten in a regular and s}mietncal way. If it is necessary to replace a gasket, it is recommended to oil it in the case of metallic corrugated or of ring Joint. The tightenmg of the stud bohl shall be done symetrically .

GENERAL 1/ INTRODUCTION. This manual is used for standard maintenance operation support for bolted bonnet and pressure seal bonnet gate, globe and swing check valves, from class 150 lbs up to 2500 lbs. In case of a specific work to be perform on the valves, additional informations can be obtain from MALBRANQUE upon written request. Other operations than usual valve maintenance may infringe Malbranque guarantee. 2/ RECOMMENDATIONS. 2.1. WARNING The following recommendations are resulting of our industrial valve manufacturer experience. They are a general guide which cannot cover all different and particular situations met during unit/site installation. However, it brings to the fore absolute and permanent recommendations which, if they are transgressed, may compromise people safety, material and plant durability. 2.2. EQUIPMENT STORAGE When valves are not immediately installed after delivery, following rules must be apply. Keep the valves as long as possible in their original packing. When valves are laid out from original packing, store the valves in a clean and protected area in closed position with their original protections ( end connections taps, locking devices....), to prevent particles contamination of internal volumes, until their installation on pipe. When possible, keep material from bad weather conditions to prevent sand, dust or any other particles which can form with grease, an abrasive paste , on the stem. 3. INSTALLATION OF THE EQUIPMENT 3.1. HANDLING OF THE EQUIPMENT While handling, the equipment shall be slung under the body or by handling devices (if existing) but not through the handwheel, the yoke, the actuator or the bonnet. Avoid chocks which can result in tightness and external coating damages Don't drag material on the ground. As the seating surfaces are one of the most important portion of any valve for obtaining it's effective function, an extensive attention shall be paid as not to scratch and/or cause damage to this area.

3.2. ASSEMBLING ON PIPE Prior to assembling on pipe, remove all end connections taps and clean the inside of the valve as well as the flange gaskets surfaces. NOTA: Internal parts of cryogenic service valves must be properly dried out and grease free. Check that there are no metal cutting, welding spots or any other material in the piping that could damage the sealing surfaces. Check that the disc of check valve is not blocked by any wooden piece eventually installed for transport. On installation, check the marking of valve, name plate/tag being attached to each valve which describes Rating, Size, Shell and trim material, or flow direction or others, in order to avoid mistakes or confusion. Check The alignment of the two pipe sections, the pipe connecting flanges or butt weld ends preparation parallelism and distance. Under no circumstances the flanges or the butt-welding ends valves shall be used to correct a defect relating to the above points. Installation direction of a gate valve is normally free but must be performed in accordance with indicated flow marking if the disc is provided with a pressure balance hole or by-pass system ( see arrow or special marking on valve for flow direction). Since the flow direction of check and globe valve is clearly marked, install them as being instructed. As far as possible, assemble the valve on the pipe in a vertical position with hand wheel or actuator on top of the pipe. In case of butt weld ends type valves, welding to the line and post weld heat treatment operation shall be performed with the valve in half opened position. For local annealing, keep the temperature within required range and never give excessive heat transfer to the valve seat area. Also welding slags or spatters shall be completely cleaned off because majority of troubles on a valve attributes to its seat surface damage caused with weld spatter or other foreign material damaging the sealing surfaces. 4.STARTING AND OPERATING OF THE INSTALLATION After a long storage of the equipment, when the installation is pressurized a leak can appear at the stuffing box. It is then necessary to tighten the gland bolting. It's also essential to check and if necessary to tighten up the body bonnet bolting. For in situ tests and start up of the installation, never drain the valves thru the packing or the shaft plug (for check valves) Gate valves shall be used either in full opened or completely closed position. If used in partially position, vibration on the disc may occurred with high speed flow, and damage the disc and seats sealing surfaces. As far as service conditions allow it, it is very important to regularly perform an opening-closing movement (even partial) of valves which stay in same position for a long period.

5/ VALVES FITTED WITH ACTUATORS For the electric connection of motor operated valve the cover junction box has to be removed for the shortest time to avoid water coming into the electric organs.

6/ MAINTENANCE THIS GIVES ONLY RECOMMENDATIONS FOR BASIC MAINTENANCE OPERATIONS . YOU WILL FIND ATTACHED TO THIS MANUAL DIFFERENT NM, IM AND BE REFERENCED DOCUMENTS FOR TECHNICAL HELP AND INFORMATIONS . 6.1. USUAL M AINTENANCE 6.1.1 Retightening of stuffing box on gate and globe valves When a leak appears at the stuffing box, retighten in order to increase the pressure on the packing. This force is developed by retightening the nuts progressively and alternatively to maintain the gland flange parallel to the upper bonnet flange. On motor operated valves an excessive operating torque may generate an unexpected operation of the torque switches that are protecting the motor. In the event the leakage persists the packing needs to be replaced. 6.1.2 Lubrication of stem on gate and globe valves In order to guarantee a good efficie ncy of the material, it is recommended to grease regularly the stem threads .(There is no specific requirement regarding periodicity). For valve with non rising handwheel (mostly gate valves), the lubricating is made by using the lubrication plug. For valve with rising handwheel (mostly globe valve), the lubricating is made directly on the stem threads with a paint brush.

Swing check valve does not require any usual maintenance.

6.2. SPECIAL M AINTENANCE 6.2.1. Replacement of packing (only original spares must be used) Shall be done when leaking of the stuffing box cannot be stop by retightening or as per end user recommendations 6.2.2. Replacement of Bonnet gasket (only original spares must be used) Shall be done every time body /bonnet are disconnected or as per end user recommendations
