Specialist in API 5L Seamless Pipe

API 5L Seamless Pipe

Any API 5L Pipe Manufacturer In India would recommend using this ISO endorsed pipes to be used across various industries including conveying gas and water as well as in oil in the oil and natural gas industries. Both seamless and API 5L Welded Pipe steel line pipes are covered by the API 5L specification. Moreover, Pipeline steel is usually coated, which is why these line pipes tend to be resistant to crack propagation. The API 5L Seamless Pipe can be manufactured by either cold drawing in order to achieve a smoother surface or by finishing it. It is interesting to note that the composition of both welded, as well as seamless tubes produced under this specification, differs.

API 5L Seamless Pipe

For instance, the API 5L Erw Pipe has a much stricter control on sulphur and on the content of carbon, which would then affect its weldability. The technical committee authoring the standards acknowledge the fact that there are two basic Product Specifications Levels or shortened as PSL of technical requirements. Hence, this technical committee developed and labelled them as PSL 1 and PSL 2. Typically, API 5L PSL1 is a standard quality to be used for line pipe. And the committee segregated and highlighted additional requirements in the form of either chemical, mechanical properties, or testing to be under the API 5L PSL2.
