13、t 2001 American Petroleum InstituteFOREWORDa. This specication is under the jurisdiction of the American Petroleum Institute Subcom-mittee on Fiberglass and Plastic Tubulars.b. The purpose of this specication is to provide standards for low pressure berglass linepipe and ttings for use in conveying
14、produced uids including oil, gas, nonpotable waterand mixtures thereof in the oil and gas producing industries.c. Nothing in this specication should be interpreted as indicating a preference by the com-mittee for any material or process or as indicating equality between the various materials orproce
15、sses. In the selection of materials and processes, the purchaser must be guided by hisexperience and by the service for which the pipe is intended. d. API publications may be used by anyone desiring to do so. Every effort has been made bythe Institute to assure the accuracy and reliability of the da
16、ta contained in them; however, theInstitute makes no representation, warranty, or guarantee in connection with this publicationand hereby expressly disclaims any liability or responsibility for loss or damage resultingfrom its use or for the violation of any federal, state, or municipal regulation w

The formulation and publication of API Specications and the API monogram program isnot intended in any way to inhibit the purchase of products from companies not licensed touse the API monogram. f. The procedure for obtaining authorization to use the API mono
18、gram is given in AppendixF. g. This Standard shall become effective on the date printed on the cover but may be usedvoluntarily from the date of distribution. h. Suggested revisions are invited and should be submitted to the standardization manager,American Petroleum Institute, 1220 L Street, N.W.,

43、rs lament wound (FW) and centrif-ugally cast (CC) berglass line pipe and ttings for pipe indiameters up to and including 24 in. in diameter and up to andincluding 1000 psig cyclic operating pressures. In addition, atthe manufacturers option, the pipe may also be rated forstatic operating pressures u
44、p to 1000 psig. It is recommendedthat the pipe and ttings be purchased by cyclic pressure rat-ing. The standard pressure ratings range from 150 psig to 300psig in 50 psig increments, and from 300 psig to 1000 psig in100 psig increments, based on either cyclic pressure (ref.5.5.1) or static pressure
45、(ref. 5.5.2). Quality control tests,hydrostatic mill tests, dimensions, weights, material proper-ties, physical properties, and minimum performance require-ments are included.1.2 UNIT CONVERSIONA decimal/inch system is the standard for the dimensionsshown in this specication. Nominal sizes will cont
