Jur API 5L Steel Pipe Specification Latest 45th Edition Update According to the stress and deformation characteristics of the specimen during the flattening process, the flattening test shall show the resistance to longitudinal cracking and circumferential cracking of the pipe, and display its internal defects and surface defects. Manufacturer is audited initially and then once every 3 years thereafter to the requirements of Spec Q1 and Spec 5L 4. As the steel aoi pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Chemical composition limits are more specific and tighter for many grades? New version of API 5L is more completely, and scientific.

Dokus Thank you in advance. Includes marking of couplings and small diameter pipe bundle tags L Street, NW? For PSL1 pipe, manufacturer shall establish and follow documented procedures to maintain a. For PSL2 pipe, Besides above terms, such documents shall provide means for tracing any length of the pipe to the proper test unit, including the related chemical and mechanical test results.

It is to use radiographic, ultrasonic or other methods not to breaking the material in API 5L standard, to reveal pipe defects, imperfections. Specification permits intermediate grades L Street, NW?

A summary of some of the key requirements are: For the other content has a little difference in related standards, manufacturing technology, performances norm, inspection methods, besides adjustment of text expression. For example total meters or total pieces. Very prescriptive including the pipe attributes that must be marked on the pipe — i. Are you an Engineering professional? Minimum strength requirement on weld seams? Chemical composition limits are more specific 44thh tighter for many grades?

Bend test Cracks should not occur in any part of the sample and opening of weld shall not occur as well. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Therefore, API 5L steel line pipe should have high strength, high toughness and brittle fracture, and good weld ability, and suitable for sour services and in H2S environment with anti-corrosion performances. Linear imperfections cracks, lack of penetration or fusion Acceptance criteria for are given in Tables E.

Any one already compare between API 5L 44th with 45th edition? First, a revised ISO was balloted and published. Arc burns Laminiations Geometric deviations Hard spots Other surface imperfections Defects depth more than 0. Described in Clause 9. Testing requirements include, type of test, lot size and frequency Tables include requirements for: Defense manufacturing is all 44hh project manufacturing and project accounting.

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. Strength ali in US Customary units are converted from metric equivalents and are not rounded to the nearest thousand — Conversion results in a slightly different value than in the past?

Maximum limits on yield and tensile strength? Qualifications of visual inspectors are identified? Random length shall be delivered as below table Differences between API 5L 45th edition and previously edition The mainly difference between 45th Edition with previously is to add 2 additional appendix: As edution Letter N: Purchase order must indicate which provisions of Clause 7.

The steel line pipe production has almost applied to all new technology achievement in metallurgy field nearly 20 years. Disposition of defects is addressed in section C — Defects are treated in accordance with Clause C.

API 5L 44th ed. 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. Related Posts.

API Specification 5L, 46th Edition

On the other hand, seamless manufacturing type usually for the small diameters pipe, the pipe diameter is less than mm or 6 inch, edtion seamless steel pipe is more applied than steel pipe in welded. Except the previous situation, the pipe shall withstand the hydrostatic test without leakage through the weld seam or the pipe body. The letter L followed by the specified minimum yield strength in Mpa. Thermomechanical rolled or thermomechanical formed.


Key Changes Updated and expanded requirements for mill jointers differentiate between double-jointers and mill jointers; avoid welding consumables environmental contamination; require qualification standards; new process testing requirements; clarify offset and undercut requirements; standardize marking requirements; reference weld repair annex ; Updated requirements for pipe end squareness; Updated requirements for hardness testing on PSL 2 pipe for sour service and PSL 2 pipe for offshore service; New annex for strain-based design requirements PSL 2 pipe for applications requiring longitudinal plastic strain capacity Effective Date and Program Implications The Monogram Program effective date will be November 1, Current licensees shall ensure that products manufactured on and after November 1st, meet the requirements of API 5L 46th edition in order to be monogrammed. Also, effective November 1st, , API 5L audits will be conducted to the 46th edition of the document.
