API 5L PSL1 and PSL2 LINE PIPE For Oil and Gas Transportation

KING STEEL supplies vast range of API 5L seamless pipes and API 5L welded line pipes for oil and gas transmission, for welded pipes there're ERW line pipe, SSAW line pipe and LSAW line pipe. It has 2 major application fields: onshore line pipe and offshore line pipe. Steel pipe classes include PLS1 and PLS2. They are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc.

LINE PIPE API 5L PSL1 and PSL2 Differences

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 Line Pipe According to Manufacture Process:

API 5L PSL1 and PSL2 Seamless line pipe

For its different manufacturing process, there’re hot rolling steel tube and cold drawn seamless steel tube. Agico sells seamless line pipe available in different sizes, weights and grades, customer can choose from black line pipe and galvanized line pipe. from 2-3/8" to 24", steel grade A, B, X42 - X80.
API 5L PSL1 and PSL2 Welded line pipe
Oil and gas welded line pipe for intra-field is used to transport crude oil and natural gas from the field to oil refineries and storage facilities, as well as to shipment points and distribution nodes.
