Organization: API
Publication Date: 1 November 1992
Status: inactive
Page Count: 97
scope:

Coverage. This specification covers seamless and welded steel line pipe. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, and double-extra-strong plain-end pipe: as well as bell and spigot and through-the-flowline (TFL) pipe.

Dimensional requirements on threads and thread gages, stipulations on gaging practice, gage specifications and certification, as well as instruments and methods for inspection of threads are given in API Std 5B and are applicable to products covered by this specification.

Grades covered by this specification are A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80 and grades intermediate to the Grades X42 and higher listed. The chemical composition and mechanical properties of intermediate grades which are subject to agreement between purchaser and manufacturer must be consistent with the corresponding requirements for the grades to which the material is intermediate.

Pipe manufactured as Grade X60 or higher shall not be substituted for pipe ordered for Grade X52 or lower without purchaser approval.

This specification is under the jurisdiction of the Committee on Standardization of Tubular Goods of the American Petroleum Institute. Spec 5LS and 5LX have been incorporated into this edition of Spec 5L. Spec 5LS and 5LX, the last editions of which were published in March 1982, have been withdrawn.

The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.

Although the plain-end line pipe meeting this specification is primarily intended for field make-up by circumferential welding, the manufacturer will not assume responsibility for field welding.

For regular-weight and special plain-end pipe (special weight) as shown in Table 6.2, and for standard-weight threaded pipe larger than nominal size 12, the size designations used herein are outside-diameter sizes. For all other pipe, the size designations are nominal pipe sizes. In the text paragraphs herein, where pipe size limits (or size ranges) are given, these are outside-diameter sizes except where stated to be nominal. These outside-diameter size limits and ranges apply also to the corresponding nominal sizes.

Class II steel is rephosphorized and probably has better threading properties than Class I. Because Class II has higher chemical properties than Class I, it may be somewhat more difficult to bend.

Within this Specification:

a. "Shall" is used to indicate that a provision is mandatory.

b. "Should" is used to indicate that a provision is not mandatory, but recommended as good practice.

c. "May" is used to indicate that a provision is optional.
