Product Introduction

The API 5L Line Pipes are used in various pipeline transportations systems such as in petroleum and natural gas industries. We offer these products in customized shapes and sizes to our clients. We cover both (American Petroleum Institute)API 5L Seamless and welded pipe. They are also quite appropriate for oil and gas, conveying water. API 5L Seamless Line Pipe standardizes transportation systems in the offshore structures, materials and equipment for petrochemical, natural gas and petroleum industries. API 5L schedule 40 Pipe is being made up from High Quality of Standard Raw Materials.

There are two basic PSL(Product Specifications Levels) of the technical requirements of these pipes which is known as API 5L PSL 1 and PSL 2 Pipe. We are Largest Trusted Line Pipe Suppliers in China. PSL 1 is a standard quality for line pipe, whereas API 5L psl2 Pipe holds additional mechanical and chemical properties, along with testing requirements. Grades covered up by this specifications are A25, A, B (and the subsequent "X" Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit numbers that is followed by the letter "X", shows the Minimum Yield Strength of the pipe. We are leading API 5L Pipe Suppliers in China. We have comprehensive inventory of API 5L Seamless Line Pipe Suppliers in China in various sizes and Schedules.

API 5L line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc.

PSL is the short name of product standard level. The product standard level of line pipe have PSL1 and PSL2, also we could say the quality standard divided in PSL1 and PSL2. PSL2 is higher than PSL1, not only the inspection standard is different, also the chemical property, mechanical strength standards are different. So when place the order for the API 5L line pipe, there should be stated clearly for the size, grades these general specification, also have to clarify the production standard leve, PSL1 or PSL2.

PSL2 is more strictly than PSL1 on the chemical properties, tensile strength, non-destructive test, and impact test.

API 5L PSL1 steel line pipe not required to do the impact test.

For API 5L PSL2 steel line pipe, except Grade X80, all the other grades of API 5L line pipe required the impact test at temperature of 0℃. The average value of Akv: longitudinal direction≥41J, tranverse direction≥27J.

For API 5L Grade X80 PSL2 line pipe, at 0℃ for all the size, impact test the Akv average value: longitudinal direction≥101J, tranverse direction≥68J.

For API 5L PSL2 line pipe shall perform the hydraulic test for each single pipe, and in the API standard specification not permit to have Non-destructive test replace the hydraulic test, this also is a big difference between Chinese standard and API 5L standard. For PSL1 not required Non-destructive test, for PSL2 shall do the Non-destructive test for each single pipe.

Chemical composition and mechanical strength is also different between API 5L PSL1 line pipe and API 5L PSL2 line pipe. For the detailed specification as below. API 5L PSL2 have restrictions with the carbon equivalent content, where for the carbon mass fraction greater than 0.12%, and equal or less than 0.12%. Different CEQ shall be applied. For line pipe in PSL2 tensile strength have maximum limits.
