API 5L Grade B PSL2 Seamless Pipe,API 5L Gr. B Seamless Pipe PSL 2

API 5L Grade B PSL1 Seamless Pipe,API 5L Gr. B Seamless Pipe PSL1

API 5L Specifications covers seamless and welded pipe suitable for use in conveying gas, water, oil, and other liquefied media.

Grade designations of API 5L Line pipe offered by Trupply come from the American Petroleum Institute (API) Spec 5L Specification for line pipe. Trupply currently carries 9 grades of API 5L line pipe:

API 5L B API 5L X42 API 5L X46 API 5L X52 API 5L X56 API 5L X60 API 5L X65 API 5L X70 API 5L X80,

API 5L Grade B is one of the most common grade in API 5L line pipes.

Grade:API 5L GR.B
3) Outside Diameter:1/2″-36″
4) Wall Thinkness:SCH10–SCHXXS.
Length:2m-12m or according to the clients’ request

API 5L has 2 types of material grade,PSL1 & PSL2, Difference between PSL1 and PSL2 pipes are as follows;

  • Chemical Properties
  • Mechanical Properties
  • Manufacturing Methods
  • Inspection and Defect Repair
  • Certification & Traceability

PSL1 & PSL2 Pipe Chemical Properties

PARAMETER PSL1 PSL2
Chemistry:   Max C for Seamless pipe 0.28% for grades ≥ B 0.0024
Chemistry:   Max C for Welded pipe 0.26% for grades ≥ B 0.0022
Chemistry:   Max P 0.03% for grades ≥ A 0.0003
Chemistry:   Max S 0.0003 0.0002
Carbon   equivalent: Only when purchaser   specifies SR18 Maximum required for   each grade

Mechanical Properties

PARAMETER PSL1 PSL2
Yield strength, maximum None Maximum for each grade
UTS (Ultimate Tensile Strength) maximum None Maximum for each grade
Fracture toughness None required Required for all grades

For PSL2 pipe there is a limit on Maximum Yield & Ultimate Tensile Strength whereas for PSL1 pipe meeting the minimum requirements are sufficient. The second requirement that is mandatory for PSL2 pipe is Fracture toughness which is not required for the PSL1 pipe.

a — Pipe end includes a length of 100 mm (4.0 in) for each side
b — For SMLS pipe, the tolerances apply for 25.0 mm (0.984 in); tolerances for thicker pipes have to be as agreed.
c — For pipe with D219,1 mm (8.625 in) the diameter tolerance and the out-of-roundness tolerance may be determined by using the calculated inside diameter (the specified outside diameter minus two times the specified wall thickness) or measured inside diameter rather than the specified outside diameter

a — if the purchase order specifies a minus tolerance for wall thickness smaller than the applicable value given in this table, the plus tolerance for wall thickness shall be increased by an amount sufficient to maintain the applicable tolerance range.
b — for pipe with D ≥ 355,6 mm (14.000 in) and t ≥ 25,0 mm (0.984 in) the wall thickness tolerance locally may exceed the plus tolerance for wall thickness by an additional 0,05 t, provided that the plus tolerance for mass (see 9.14) is not exceeded.
c — The plus tolerance for wall thickness does not apply to the weld area.
d — See 9.13.2 for additional restrictions.
