Neither should anything contained in the publication be con-strued as insuring anyone against liability for infringement of letters patent.Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least everyfive years. Sometimes a one-time extension of up to two
6、years will be added to this reviewcycle. This publication will no longer be in effect five years after its publication date as anoperative API standard or, where an extension has been granted, upon republication.

32、talling, and reconditioningof fiberglass tubulars in oilfield usage. Note: No provision of this Recommended Practice shall be cause forrejection of fiberglass tubulars provided the threads are in accor-dance with the requirements of the applicable product specification.Trouble-free service and maxim
33、um safety should result ifthis Recommended Practice is followed. Fiberglass tubularsdiffer in properties from metallic tubular goods and differentinstallation techniques are required.Note: These recommendations are applicable to normal situations.Exceptional conditions may warrant different practice
34、s. It is notintended that these practices conflict with any regulatory code.It is suggested that the selection of thread compound begiven careful consideration by the user bearing in mind that asatisfactory compound should possess certain properties, themajor of which are (1) to lubricate the thread
35、 surfaces to facil-itate joint make up and break out without galling and (2) toseal voids between mating thread surfaces and effectivelyprevent leakage. Thread compounds have a significant impacton the performance of tubulars, especially under combinedloading conditions. The manufacturers recommende
36、d threadcompound, which has been qualified in accord with the APIproduct specification, should be used.CAUTION: The material safety data sheets for thread com-pounds should be read and observed. Store and dispose ofcontainers and unused compound in accord with appropriateregulations. 2 References Th

For the purposes of this recommendedpractice, the fractions and their decimal equivalents are equaland interchangeable. Metric convers
41、ions are described inAppendix F. 4 PackagingFiberglass tubulars shall be packaged so that the body andconnections are protected during shipping, unloading, stor-ing, and handling. The manufacturer shall apply external andinternal protectors of such design, material and mechanicalstrength to protect
42、the threads, and/or ends, of the tubular andcoupling from damage under normal handling and transporta-tion. External protectors shall cover the full length of thethread, or bonding area, on the pin and the internal protectorsshall cover the equivalent total thread length of the internalthread, and/o
43、r bonding surface. Protectors shall exclude for-eign matter such as dirt from the threads and from the interiorof the tubular. The protectors shall contain no compoundscapable of damaging the threads or promoting adherence ofthe protectors to the threads or bonding surfaces. Refer to theappropriate

45、eneral, and threads in particular aremade with precision and require careful handling. Whethernew, used or reconditioned, they should always be handledwith protectors in place.5.2 TRANSPORTATION5.2.1Observation of the following practices will assurethat damage to the product does not occur. The foll
46、owing pre-cautions should be taken for truck transportation: a. Trucks that haul tubulars should be the flatbed type andnot pole trailers. Bed length of the trailer should be sufficientso that no overhang occurs. b. The use of stripping under the bottom layer and betweeneach layer is recommended to
47、prevent damage to the tubulars,as well as to keep them from shifting. For nominal 30 footlengths, a minimum of four (4) stripping material supports arerecommended. Stripping material should not be placed on thetransition or upset areas of the tubing. Stripping material onthe truck bed should be no m
48、ore than six (6) feet apart, ori-ented perpendicular to the tubular body and aligned vertically,of uniform thickness within each layer and free of protrudingnails. It should be a material softer than the tubular. Strippingmust be placed as near to the end of the tubular as possibleand still maintain
49、 vertical alignment. c. Load tubulars with all couplings (box ends) on the sameend of the truck.d. Care should be taken to prevent chafing of joint shoulderson adjacent joints.e. Suitable tie-downs, such as woven cloth straps, should beused to secure the load. Caution should be used to prevent dam-aging the tubulars when securing the load. The manufacturershall endeavor to locate the tie-downs such that bending of thetubulars is minimized.For shipments other than by truck, packaging, loading andprotection procedures shall be agreed upon between the pur-chaser and the manufacturer. 5.3 HA
