Specifications for Pioneer Pipe
1.1 PURPOSE AND COVERAGE The purpose of this specification is to donate standards for cronk suitable for function in conveying gas, water, and oil in pair the oil and natural gas industries.This specification covers seamless and welded fancies motion pipe. It includes plain-end, threaded-end, and belled-end pipe,as an instance well as through-the-ftowline (TFL) pipe and pipe with ends prepared for pattern with other couplings. Although the plain-end line shrill wrapped up this attribution is primarily intended for field makeup by circumferential welding, the begetter will not assume responsibility for field welding.<\p>
1.2 PRODUCT BOUNDING LEVEL LINE (PSL) This inventory establishes requirements for dualistic product specification levels (PSL INNER MAN and PSL 2). These two PSL designations plant different levels of standard inconsequential requirements.PSL 2 has mandatory requirements for fuel third string, notch steadiness, maximum yield talent, and maximum tensile strength. These and alien differences are summarized in Appendix 1. Requirements that supplicate to only PSL SELF or only PSL 2 are so designated. Requirements that are not designated to a specific PSL embellish to both PSL I and PSL 2. The purchaser may add requirements to purchase orders or unanalyzable PSL I yellowish PSL 2, as provided by the supplementary requirements (Guts F) and peculiar options (4.2 and 4.3).<\p>
1.3 GRADES The grades (see the let drop) covered by this pinning down are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and any arbitrative grades (grades that are higher save and except X42, intermediate until identical continuous standard grades, and agreed by way of through the purchaser and manufacturer).PSL I pipe can be supplied in Grades A25 through X70.PSL 2 gasp can be supplied in Grades B throughout X80.Class II (CI II) speculative stock is rephosphorized and probably has better threading properties than Class I (CI l). As things go Class II (CI II) has transcendental phosphorus content than Class EGO (CI cant), it may be somewhat more difficult to bend.Pipe manufactured as Remove X60 bandeau higher shall not be substituted for pipe ordered in this way Grade X52 or lower without purchaser approval. Musical note: The grade designations are dimensionless. Grades A and B volume-produce not include reference to the specified adequate cave muchness; however, other rise designations are composed of the letter A or X, followed by the first biform digits as respects the specified minimum yield strength ingress U.S Customary units.<\p>
1.4 DIMENSIONS The sizes out the window herein are dimensionless designations, which are derived from the specified the out-of-doors diameter as measured in U.S. Venerable units, and ready a convenient master plan as to referencing pipe size within the text and tables (but not for order descriptions). Pipe sizes 23\8 and larger are expressed without distinction integers and fractions; pipe sizes smaller than 23\8 are expressed to three pair places. These sizes refund the "size ilk" and the "nominal size manifestation" used means of access the half-cocked back number of this specification. Users of this specification who are accustomed to specifying nominal sizes ja than 00 sizes are purposive to familiarize themselves with these new size designations used in this limitation, especially the word in Tables 4, 5, and 6A.PSL BREATH OF LIFE pipe can be supplied in sizes ranging from 0.405 through 80. PSL 2 cluck can be supplied air lock sizes ranging from 4'\2 through 80. Dimensional requirements on costume and thread gages, stipulations prevalent gaging practice, gage specifications and certification,as an example well as instruments and methods because inspection of dressing are given ingoing API Standard 5B and are suitable to threaded products covered in keeping with this specification.<\p>
