API 5L line pipe for oil & gas

What is API 5L line pipe?

API 5L line pipe is a type of pipe which is made of high strength carbon steel. It is typically manufactured based on metallurgical specifications that were developed by the American Petroleum Institute (API), which defines the standard for the dimension, physical, mechanical and chemical properties of steel. There are two grade API 5L PSL1 and PSL2, the technical requirements of PSL2 are higher than PSL1, and some pipelines under special working conditions need to adopt PSL2. 

API 5L Line pipe is mainly used to transport oil, natural gas and other fuels, which is divided into 8 kinds according to the production process, Such as seamless steel pipe, Electric-Resistance Arc Welding, Longigudinally Submerged Arc Welding, Spirally Submerged Arc Welding and other four kinds.

What is the difference between PSL1 and PSL2 standards?

When it comes to API, we all know that there are two standards, PSL1 and PSL2. PSL stands for Product Specification level. The product specification level of the pipeline is divided into PSL1 and PSL2. and the quality level is also divided into PSL1 and PSL2. Although there is only one word difference, the content of the two standards is very different. Let me elaborate on the difference between PSL1 and PSL2 as follows:

  1. PSL2 is higher than PSL1, and these two specification levels have different requirements not only for inspection, but also for chemical composition and mechanical properties.
  2. PSL1 does not require impact performance, but PSL2 all steel grades except X80, full size, have certain requirements for impact performance.
  3. The line pipe should be hydrostatic test one by one, and the standard does not allow nondestructive replacement of water pressure. PSL1 does not require nondestructive testing, while PSL2 should be tested on a per-ship basis.

In short, when ordering according to API 5L, the terms in the contract must indicate the standard grade of the product, that is, PSL1 or PSL2, in addition to the usual indicators such as specifications and steel grade. PSL2 is stricter than PSL1 in chemical composition, tensile properties, impact energy, nondestructive testing and other indexes.

What is the application of line pipe?

Line pipe has strong advantages, such as high temperature resistance and loss reduction. And the pipe is generally very strong, so it can be durable.

  • Transportation of oil, various gases and liquefied gas in chemical industry, petroleum industry and more.
  • Large plants heating and water supply systems.
  • In urban construction, line pipes are also used as transport carriers for gas and natural gas to provide clean, environmentally friendly, energy-efficient new energy for the city.
