While these pipes are available in both seamless and welded variations, the major difference between them is the weld seam on the longitudinal cross section of the ISO 3183 L485 Pipe. The carbon steel Api 5l X70 Seamless Pipes are much harder and durable due to the absence of a seam. API 5L L360 PipeAPI 5L Gr.

API 5L is suitable for conveying gas, water, and oil.
As for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe. Thus, inevitably, many T-shaped welding seams would appear in this welding Grooving corrosion of seam welded oil pipelines Oct 01, 2014 · The results obtained from chemical, microstructure, hardness, and tensile tests indicate the conformity of the pipe material with API 5L standard, grade X-42. Non-destructive testing using dye penetrant showed that the lack of side wall fusion and incomplete penetration of the seam weld line were the dominant defects. Longitudinal weld seam on piping.Sep 25, 2005 · Even if the Code says nothing, it's good engineering practice to stagger the longitudinal welds in welded pipes (API 5L for example). An analogy would be a storage tank or a pressure vessel, where the longitudinal welds are staggered, and in these cases the appplicable codes (ASME VIII for pressure vessels, API 650 for oil storage, AWWA D100

Welded Pipes. a. EFW Pipe i. Longitudinally Welded Pipe->Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld.

Mar 22, 2007 · The case is that someone told me, that longitudinal welded pipes are EXCLUDED from API 5L, so we put explicitly in the contract conditions to use helicoidal welded pipes. Now my question is, if that is true. Because if not we could also permit longitudinal welded pipes as long as the fabricant satisfy the criteria of the API standard.
