API 5L steel line pipe adopts different steel grades, generally are Gr. This version was started from Aprilwith collecting and analyzing of more than suggestions, finally released at the end of Requirement PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties.

Grade designations for PSL 2 contain a delivery condition, e. At present, the development trend of line pipe engineering is large diameter, high pressure gas transportation, high cold and corrosion service environment, thick wall of submarine pipeline etc.

This standard is not applicable to cast pipe. Any one already compare between API 5L 44th with 45th edition? For example, L X42 means the minimum yield strength editjon Mpa. In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. The best requirements of both standards were adopted?

So how much do you know about API 5L pipe and why it is getting so popular and editioj in pipeline industries? Individual annexes applicability of confirmation. Thank you in advance.

By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm. Strength levels in US Customary units are converted from metric equivalents and are not rounded to the nearest thousand — Conversion results in a slightly different 5ll than in the past? Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

The steel line pipe production has almost edotion to all new technology achievement in metallurgy field nearly 20 years.

API 5L Steel Pipe Specification (Latest 45th Edition Update)

Maximum limits on yield and tensile strength? Current 44th edition includes: Chemical composition limits are more specific and tighter for many grades? Specification permits intermediate grades L Street, NW? Ali flattening test method is used to verify the deformation performance of line pipe to the specified size, and display its defects.

Tempered and quenched Letter M: As rolled Letter N: Testing requirements include, type of test, lot size and frequency Tables include requirements for: For all bend test, the weld extends to a distance of 6. With less raw material cost, simplified and uniform production procedures, welded steel pipe has taken the first place in oil and gas line pipe industries. More over, for the same grade API 5L pipe, seamless and welded chemical elements content is different, which welded pipe is required more strictly and lower on Carbon and Sulfur.

PSL is the abbreviation of product specification level. First, a revised ISO was balloted and published. Close this window and log in. The letter X followed by a two or three digital number equal to the minimum yield strength in psi rounded down to the nearest integer and, for PSL2 pipe, the letter describing the delivery condition R, N, Q, or M consist with the above formats.

The letter L followed by the specified minimum yield strength in Mpa. Thermomechanical rolled or thermomechanical formed.

Register now while it’s still free! But the latest version of ISO It is to use radiographic, ultrasonic or other methods not to breaking the material in API 5L standard, to reveal pipe defects, imperfections. Very prescriptive including the pipe attributes that must be marked on the pipe — i.

OD Outside diameter and WT pipe wall thickness g: Minimum strength requirement on weld seams? Other than above three common tests there are other tests that required in each circumstances.

API 5L pipe length tolerances shall be complied as following conditions: On the other hand, seamless manufacturing type usually for the small diameters pipe, the pipe diameter is less than mm or 6 inch, the seamless steel pipe 44tn more applied than steel pipe in welded.
