35、 for Repair, Testing and Setting Gas Lift Valves1 ScopeRecommended Practice 11V7 applies to repair, testing, and setting gas lift valves and reverse ow (check) valves. This is a recommended practice to present guidelines related to the repair and reuse of valves; these practices are intended to serv

36、e both repair shops and operators. API RP 11V7 refers to test procedures used in API Specication 11V1 and Recom- mended Practice 11V2. Portions of these procedures are included in the appendices of this document. The injection gas pressure operated (IPO) bellows valve is one example of a commonly re

37、paired valve; the spring loaded production pressure operated (PPO) valve is also covered. Other valves, including bellows charged valves in production pressure operated service should be repaired according to the guidelines, however specialty valves are best repaired at the original manufacturers sh

PVOT:Test rack opening pressure at specied temperature (T).IPO: Injection pressure operated gas lift valve.PPO:Production pressure operated gas lift valve.4 Gas Lift Valve Designation and Construction4.1 VALVE DESIGNATIONThe code for designation of particular gas lift valv

40、es is pre- sented in API Spec 11V1. The designation code identies a valve as wireline or tubing retrievable, injection gas, spring or combination closing force, type of valveproduction pres- sure operated or gas injection pressure operated, size, etc. This basic designation code should apply to rebu

41、ilt as well as new valves. The rebuilder must permanently mark or etch the valve with date (MO/YR), Pvo, port size, and their name, symbol, or trademark for valve identication The valve should be marked using a low stress stamp or etching.4.2 DESIGNThe gas lift valves and reverse ow (check) valves t

42、hat are rebuilt according to this Recommended Practice should adhere to API Spec 11V1, as applied to component inter- changeability, dimensional tolerance of components, packing diameters of wireline retrievable devices, and methods of attachment to provide leak free connections. Component parts sho

43、uld be selected to permit interchange- ability within one type or model line. Dimensions and dimen- sional tolerances of the components of the valves to be rebuilt should not prevent proper operation of the assembled device.4.3 MATERIAL REQUIREMENTSThe material guidelines for metals and elastomers o

44、f the valves to be rebuilt are found in API Spec 11V1. For the initial valve installation in an H2S environment, new equipment is recommended and should comply with NACE MR-01-75. Subsequent replacement equipment should be rebuilt from valves whose components comply with the NACE specication. For ex

45、ample, the operator can use valves which come from the original completion and specify the components to maintain NACE compliance. Since alloy specications in used (exchanged) valves can- not be determined without extensive metallurgical testing, all metals should be assumed to be standard alloys of

46、 stainless steel or monel. Replacement parts should be made of stan- dard alloys equivalent to those provided by the original manu- facturer or as agreed between the repair shop and user. Seats and stems are easily replaced and materials for these components can be specied.4.4 EQUIPMENT REPAIR TERMI

47、NOLOGY 4.4.1 Rebuilt to Original Equipment Specication The terms implying restoration to original (new) equip- ment specications shall be applied to used equipment only when the replacement components match the original manu- facturers specications. These specications should be avail- able to the op

48、erator (purchaser). The term shall not be applied to valve brands and models that have been discontinued. The intent is to prevent use of the terminology when specications are not available for comparison.1NACE International, 1440 South Creek Drive, P.O. Box 218340, Houston, Texas 77218-8340. 2 API

49、11V74.4.2 Repaired Equipment per API Recommended Practice 11V7All equipment restored according to this Recommended Practice can be referred to as repaired equipment per API RP 11V7. All repair facilities should have readily available writ- ten procedures for inspection, disassembly, reassembly, and testing of gas lift equipment.4.4.3 Cleaned and ResetAll equipment that is only cleaned and the (test rack) open- ing pressure reset shall be referred to as cleaned and reset. Equipment in this category will not be stamped as is specied in 4.1 and will not
