API 5L X46 pipe is known to be high performance and heavy duty. Hence, X46 Grade Pipe, X46 Line Pipe, X46 Lsaw Pipe, API 5L Gr X 46 ERW, are used in industries like petroleum and natural gas. API 5L X46 erw pipe, Api 5l X46 Pipe Suppliers carries or transport across fluid or gas for example gas, steam, water and oil from offshore sites to the factories or refineries. These industries require Steel X46 Pipe that can deliver high performance and critical service while maintaining tight tolerances.
The quality standard specification for these products or pipes is the API 5L X46 PSL1. Since the requirements for the pipe API 5L X46 PSL2 is different from the PSL1, the testing parameters and requirements along with its mechanical and chemical properties. While it is compulsory that the PSL2 undergo impact test and non-destructive inspection, it is not required that the PSL1 undergo these tests or inspections. Some features of the tuberia API 5L X46 include seamless finishing, high durability, dimensional accuracy, cut resistance, robust design, strong construction and precise dimension. Besides these features, API 5L X46 equivalent pipes have good weldability and machinability properties. The tensile strength of is 435 Mpa, while its yield strength is 320 Mpa.
These X46 Carbon Steel Pipe such as L320 Pipe, API 5L X46 PSL1 Pipe, API 5L X46 Grade B, API 5L X46 Dsaw & API 5L X46 PSL2 Pipe have high resistance to corrosion against acids, cold conditions and specifically against H2S or Hydrogen sulphide. When Hydrogen sulphide reacts with fluids like water, it releases free Hydrogen which attaches itself on the walls of the API 5L Grade X46 Pipe and could cause sulphide stress corrosion cracking. Therefore, X46 Pipe Material are well suited to sour service.

Check the below formula to calculate 20% SMYS of X46 Pipe
Class 3 design = 2 x 42,000 x 0.250 / 12.75 x 0.50 x 1 x 1 = 823 psig But anything over 329 MAOP will cause it to be a transmission line
