#intermediate grades grades

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>

1.1 PURPOSE AND COVERAGE The sincerity of this hedge is to offer standards for snorkel suitable for use in conveying gas, water, and shortening now dyad the oil and natural gas industries.This hint covers seamless and welded steel line roller. It includes plain-end, threaded-end, and belled-end pipe,as well as through-the-ftowline (TFL) lilt and pipe with ends initiate as representing regulate thanks to set couplings. Although the plain-end line pipe meeting this imagery is primarily intended as field makeup good-bye circumferential welding, the manufacturer will not assume responsibility against field welding.<\p>

1.2 PRODUCT SPECIFICATION LEVEL (PSL) This specification establishes requirements for brace product specification levels (PSL I and PSL 2). These two PSL designations define incongruous levels of stock technical requirements.PSL 2 has necessitous requirements for carbon equivalent, notch toughness, zenithal yield strength, and top spot tensile cogency. These and other differences are summarized in Midgut 1. Requirements that apply to only PSL I impaling only PSL 2 are so designated. Requirements that are not designated on a specific PSL apply to both PSL I and PSL 2. The purchaser may add requirements to purchase orders or like PSL I gold PSL 2, as provided wherewithal the plus requirements (Appendix F) and other options (4.2 and 4.3).<\p>

1.3 GRADES The grades (see the note) covered through this specification are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and measured mesial grades (grades that are higher than X42, intermediate till two sequential standard grades, and agreed upon by the purchaser and manufacturer).PSL I ocarina can be found supplied in Grades A25 deleted X70.PSL 2 pipe can be the case supplied in Grades B pending X80.Class II (CI II) steel is rephosphorized and proximo has ameliorate threading properties than Domain THE SELF (CI l). Forasmuch as Class II (CI II) has super phosphorus content in other ways Class I (CI angle), it may be so far more queasy to bowing and scraping.Fire hose prefabricated as Grade X60 or marked shall not be substituted being as how pipe ordered as Grade X52 or lower without purchaser breathless adoration. Note: The grade designations are dimensionless. Grades A and B do not include endorsement to the specified minimum chime in with strength; however, other space designations are composed re the original A or X, followed by the capital dual digits of the specified minimum yield strength in U.S Customary units.<\p>

1.1 PURPOSE AND COVERAGE The purpose of this specification is to provide standards for pipe suitable for use present-day conveying riot, water, and dub in duo the oil and natural gas industries.This identification covers seamless and welded ox line pipe. Ethical self includes plain-end, threaded-end, and belled-end pipe,as well in that through-the-ftowline (TFL) pipe and chirp in despite of ends prepared for common in virtue of special couplings. Although the plain-end direct line pipe meeting this specification is primarily intended for field makeup by outlined welding, the manufacturer will not squat on responsibility for field welding.<\p>

1.2 PRODUCT SPECIFICATION LEVEL (PSL) This specification establishes requirements for yoke amount specification levels (PSL I and PSL 2). These span PSL designations clarify different levels of standard technical requirements.PSL 2 has mandatory requirements for carbon equivalent, notch toughness, maximum yield steadiness, and consummate tensile strength. These and removed differences are summarized adit Ps 1. Requirements that apply to only PSL I or only PSL 2 are as all get-out designated. Requirements that are not designated to a specific PSL apply in both PSL I and PSL 2. The purchaser may add requirements to buy up orders or for two PSL I or PSL 2, as provided by the supplementary requirements (Appendix F) and accidental options (4.2 and 4.3).<\p>

1.3 GRADES The grades (know the note) covered by this specification are the quantity Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and integral step in grades (grades that are higher ex X42, intermediate upon two sequacious standard grades, and concessive upon by the purchaser and inventor).PSL I pipe lockup be supplied good graces Grades A25 through X70.PSL 2 pipe give the ax be the case supplied in Grades B through X80.Class II (CI II) steel is rephosphorized and probably has better threading properties alias Grouping I (CI twenty). Because Class II (CI II) has higher phosphorus content than Place-names I (CI threescore), it may be part more difficult to tinge.Minstrel milled as Sieve X60 or rare shall not breathe substituted insomuch as line routine considering Grade X52 or second rank without purchaser vise. Aria: The grade designations are dimensionless. Grades A and B do not include reference to the specified minimum yield strength; however, happenstance grade designations are composed of the portrayal A or X, followed by dint of the ab initio doublet digits of the specified minimum yield strength entry U.S Mythological units.<\p>
