Api 5l latest edition free download

This standard is not applicable to cast pipe. In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. Meanwhile other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes. Seamless manufacturing type usually for the small diameters pipe, normally diameter under 24 inch. For the pipe diameter is less than mm or 6 inch, the seamless steel pipe is more applied than steel pipe in welded.

There are also big diameters seamless pipe. By hot rolled manufacturing process we could get seamless pipe diameters at most 20 inch mm. As the development of pipeline steel plate making technology, pipe forming and welding technology also has been much improved, so a lot of ERW pipe and SAW pipe used in the pipeline constructions.

Specially for the big diameter steel pipe, SAW pipe gains a great advantage. 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. API 5L steel line pipe adopts different steel grades, generally are Gr.

Some manufacturers are capable of manufacturing steel grade up to X and X As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances.

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. By different delivery condition, there are also As-rolled, normalizing rolled, thermomechanical rolled, normalizing formed, normalized, normalized and tempered, quenched and tempered. The letter L followed by the specified minimum yield strength in Mpa.

For example, L X42 means the minimum yield strength is Mpa. 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.

PSL is the abbreviation of product specification level.

Linear imperfections cracks, lack of penetration or fusion Acceptance criteria for are given in Tables E. At present, the development ali of line pipe engineering is large diameter, high pressure gas transportation, high cold and corrosion service environment, thick wall of submarine pipeline etc.

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 is more applied than steel pipe in welded. Random length shall be delivered as below table OD Outside diameter and WT pipe wall thickness g: Following additional information also could be included in the PO in different situations.

October 1, ISO Very prescriptive including the pipe attributes that must be marked on the pipe — i. PSL is the abbreviation of product specification level. Section contains a list of the pertinent test and examination records? PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties. Requirement PSL1 and PSL2 are not only different for testing requirements, but also for chemical composition and mechanical properties.

A section containing the defect is removed by cutting? A single gas metal Arc pass? Meanwhile, other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes. Current 44th edition includes: Where can I get that summary of 45th edition improvement?
