Table of contents
API X70 steel pipe is a carbon-based steel pipe which contains alloying compounds. Besides carbon, the API 5L X70 material include silicon, manganese, phosphorus, sulphur and niobium. The percentage of manganese and Silicon are higher in the alloy used to make API 5L X70 tubular pipes, API 5L X70 Seamless Pipe Suppliers. And elements like phosphorus, sulphur and niobium are found in trace amounts. The inclusion of these compounds in the alloy gives the X70 Pipe Material increased mechanical properties.
The required minimum yield strength for l485m steel pipe is 70300 psi or 485 Mpa while the minimum tensile strength is around 92100 psi or 635 Mpa. X70 Lsaw Pipe have diameters that fall in the range of 18” to 56”. The surface of tubo API 5L gr x70 is treated with either black oil paint, anti-corrosion oil, varnish, tape wrap, FBE, 3LPE, 3LPP, coal tar, PE or they could be colour coated. The surface of API 5L X70 seamless pipes could be coated with concrete or heat marked. While the surface of these API 5L Grade X70 Pipe can be either varnished or oiled externally, they could be left bare and unprotected as required by the buyer. L485 pipes can also be galvanized, through either the hot or cold process. Longitudinal Welded pipes that are galvanized will have excellent resistance to rusting.
The zinc alloy that gets deposited on the ISO 3183 L485 Pipe, API 5L X70 Seamless Pipe Suppliers forms a protective layer on the X70 Grade Pipe to prevent corrosion from occurring. There are 2 levels of the product specification for the API 5L X70 Grade B Pipe. One is the API 5L X70 PSL1 Pipe which is considered to be a standard quality of pipes, and the other one is the API 5L X70 PSL2 Pipe. The PSL2 has better performance as compared to the API 5L X70 PSL1 Pipe because of the difference in its chemical and mechanical properties. Additionally, the testing parameters of API 5L X70 PSL1/ PSL2 Carbon Steel Pipe supplier and the quality inspections for both the PSL1 Steel X70 Pipe & the API 5L Gr X 70 PSL2 are different from each other.

Check the below formula to calculate 20% SMYS of X70 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
