API 5L X65 Pipe Line

During the production process, smelting analysis and product analysis must be carried out to ensure that the chemical composition of the steel pipe meets the requirements of API 5L standard. For X65 steel pipe, the specific requirements for chemical composition are as follows:
Carbon (C): maximum 0.28% for seamless pipes and maximum 0.26% for welded pipes.
Manganese (Mn): maximum 1.40% for seamless pipes and maximum 1.45% for welded pipes.
Phosphorus (P): maximum 0.030%.
Sulfur (S): maximum 0.030%.
Other elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), etc. also have corresponding maximum content limits, such as maximum 0.50% for chromium and nickel, and maximum 0.15% for molybdenum.
Sampling and testing:

According to the provisions of GB/T 20066, sampling and testing of chemical composition are carried out. Standard methods such as GB/T 4336 and GB/T 20123 are usually used for analysis to ensure the accuracy and reliability of the results.
Quality Control:

During the production process, strict quality control procedures are implemented, including regular inspections and tests, to ensure that each batch of steel pipes meets the chemical composition requirements.
