What is the difference between API 5L X52 PSL1 pipe and API 5L X52 PSL2 tube

API 5L generally refers to the implementation standards of pipeline steel pipe. API 5L X52 pipe is used to deliver oil, steam, water, etc. to oil and gas industry enterprises.

There are two standards for API 5L X52 pipe. They are API 5L X52 PSL1 pipe and API 5L X52 PSL2 tube. Although there is only one word difference, but the contents of these two standards are quite different. Now we’ll talk about the difference between API 5L X52 PSL1 pipe and API 5L X52 PSL2 tube in detail:

1, API 5L X52 PSL2 tube is higher than API 5L X52 PSL1 pipe, and these 2 standards are not only different in inspection requirements, but also in chemical composition and mechanical properties. So when order API 5L X52 steel pipe, the terms of the contract must also indicate the standard of product specification, that is, PSL1 or PSL2. PSL2 is more strict than PSL1 in terms of chemical composition, tensile properties, impact energy and nondestructive testing.

2, API 5L X52 PSL1 pipe does not require impact performance.

3, API 5L X52 pipe should be done water pressure test, and the standard does not allow NDT to replace water pressure test. API 5L X52 PSL1 pipe does not require nondestructive testing, and API 5L X52 PSL2 tube shall be done nondestructive test one by one.
