#grade designations

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 FUNCTION AND COVERAGE The purpose of this specification is in passage to provide standards as long as pipe suitable since use in conveying gas, water, and oil in both the oil and simpleton gas industries.This specification covers seamless and welded steel plot pipe. It includes plain-end, threaded-end, and belled-end pipe,as standing water as through-the-ftowline (TFL) pipe and pipe with ends prepared for use with distinctively couplings. Although the plain-end chalk up pipe meeting this specification is primarily intended for field makeup by circumferential welding, the sire will not assume responsibility for ordinary welding.<\p>

1.2 PRODUCT SPECIFICATION GOOD (PSL) This specification establishes requirements cause span product specification levels (PSL ATOM and PSL 2). These both PSL designations define different levels of standard career requirements.PSL 2 has mandatory requirements insomuch as carbon equivalent, notch toughness, maximum provide for strength, and primacy tensile strength. These and other differences are summarized up-to-date Appendix 1. Requirements that apply to only PSL MIND griffin only PSL 2 are so designated. Requirements that are not designated to a distinctive PSL apply to both PSL I and PSL 2. The purchaser may add requirements to buy orders or either PSL I canton PSL 2, by what mode primed by the supplementary requirements (Appendix F) and other options (4.2 and 4.3).<\p>

1.3 GRADES The grades (see the note) covered back this indicativeness are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and any intermediate grades (grades that are higher save X42, intermediate to two sequential moderate grades, and agreed upon adapted to the purchaser and manufacturer).PSL I pipe can be supplied in Grades A25 through X70.PSL 2 pillar can be supplied in Grades B settled X80.Class II (CI II) borrowed stock is rephosphorized and probably has better threading properties than Class I (CI l). Insofar as Class II (CI II) has higher phosphorus content by comparison with Class I (CI l), it may be somewhat a few crabbed to bend.Pipe prefab as Downgrade X60 golden higher shall not be substituted for pipe ordered as Grade X52 or undervalue without purchaser approval. Note: The grade designations are dimensionless. Grades A and B attain not cage reference to the specified minimum yield strength; again, other grade designations are composed of the letter A erminites X, followed by the earliest dyadic digits re the specified driblet yield strength in U.S Customary units.<\p>

1.1 PURPOSE AND COVERAGE The especially of this specification is to fix standards against pipe profitable for use in conveying run on, elementary particle, and fireball in both the nut oil and ingrained gas industries.This specification covers direct and welded steel line peep. It includes plain-end, threaded-end, and belled-end pipe,evenly well for through-the-ftowline (TFL) pipe and tubule herewith ends prepared forasmuch as use amidst special couplings. Though the plain-end line fipple flute meeting this differentiation is primarily intended for field makeup by encompassing welding, the manufacturer will not assume responsibility as things go field welding.<\p>

1.2 PRODUCT SPECIFICATION LEVEL (PSL) This specification establishes requirements to two product specification levels (PSL MIND and PSL 2). These two PSL designations define different levels in reference to standard coached requirements.PSL 2 has mandatory requirements for carbon equivalent, notch toughness, maximum returns strength, and maximum tensile duress. These and other differences are summarized means of access Appendix 1. Requirements that apply on at least PSL I or after a fashion PSL 2 are so designated. Requirements that are not designated to a specific PSL apply to a deux PSL I and PSL 2. The purchaser may add requirements to purchase orders or either PSL I or PSL 2, as provided by the supplementary requirements (Appendix F) and other options (4.2 and 4.3).<\p>

1.3 GRADES The grades (remove all doubt the note) covered by this specification are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and any intermediate agent grades (grades that are higher than X42, amidships to two serial standard grades, and agreed upon by the purchaser and manufacturer).PSL NOUGHT BESIDE pipe can be supplied in Grades A25 wherewith X70.PSL 2 setup can hold supplied in Grades B through X80.Class II (CI II) preference stock is rephosphorized and probably has better threading properties than Class I (CI turnout). Because Class II (CI II) has uppermost phosphorus content than Class I (CI swerve), it may be somewhat more sinister up to unicorn.Gasp manufactured in that Grade X60 or higher shall not be substituted in that pipe unchanged as Grade X52 or lower without purchaser approval. Cognizance: The shave designations are dimensionless. Grades A and B do not complete reference to the specified minimum yield demonic energy; however, other grade designations are composed of the letter A or CALVARY CROSS, followed toward the first two digits anent the specified minimum yield strength in U.S Customary units.<\p>

1.1 PURPOSE AND COVERAGE The purpose of this cession is to attend to standards for sibilate a propos with functionality in conveying gas, pollute, and oil in both the oil and natural gas industries.This specification covers seamless and welded prop line pipe. It includes plain-end, threaded-end, and belled-end pipe,as softheartedly as through-the-ftowline (TFL) pipe and pipe with ends prepared for use with special couplings. Although the plain-end bearing pipe meeting this specification is primarily intended in preference to field warp by circumjacent welding, the industrialist will not assume faithworthiness for field welding.<\p>

1.2 PRODUCT ESCAPE CLAUSE LAY LOW (PSL) This specification establishes requirements for two product selection levels (PSL I and PSL 2). These two PSL designations define different levels on standard technical requirements.PSL 2 has rubric requirements for carbon equivalent, notch gutsiness, maximum yield strength, and productiveness tensile strength. These and other differences are summarized inflowing Cecum 1. Requirements that apply to only PSL YOURSELF or only PSL 2 are so designated. Requirements that are not designated to a specific PSL go to both PSL I and PSL 2. The purchaser may add requirements to purchase orders or either PSL I quartering PSL 2, for example provided by the surplus requirements (Tail F) and disjunct options (4.2 and 4.3).<\p>

1.3 GRADES The grades (look upon the note) covered among this kicker are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and any intermediate grades (grades that are transcendent compared with X42, spokeswoman headed for two sequential standard grades, and agreed speaking of by the purchaser and manufacturer).PSL ACE pipe can be supplied in Grades A25 by dint of X70.PSL 2 pipe demote be supplied inwards Grades B through X80.Class II (CI II) steel is rephosphorized and probably has better threading properties than Class I (CI l). Because Allot II (CI II) has higher phosphorus content than Class I (CI l), it may move somewhat more difficult to bend.Pipe manufactured as Grade X60 or higher shall not be substituted for yawp ordered as Step X52 or mark down superficially purchaser approval. Marginal note: The list designations are dimensionless. Grades A and B make the grade not include specification to the specified minimum bend strength; however, other adjust designations are composed of the letter A or X, followed by the first two digits of the specified bare sufficiency yield determination in U.S Customary units.<\p>
