The minimum yield strength of API 5L X46 pipe is approximately 317 MPA. These grades of pipe have chemical and mechanical properties superior to API 5L Grade B and API 5L X42 Grade pipe. This grade is known for its heavy-duty and high performance, making it cost-effective. Due to their high mechanical strength, these pipes have a robust structure, high resistance to cuts and precise dimensions. API 5L grade PSL1 X46 pipe is often chosen by customers looking for better performance than grade B and X42 pipe.


It has excellent resistance to corrosion caused by acids, especially H2S or hydrogen sulfide. It avoids damage caused by H2S reacting with water and other liquids. API 5L X46 pipes are pipes that are highly resistant to cryogenic temperatures, acids and industrial waste. These properties make it ideal for industries such as petrochemical, petroleum, oil and gas.

These pipes are designed to provide efficient high performance with minimal wear and tear, making them the first choice of customers for use in their industries. These pipelines PSL-1 and PSL-2 have two differentiation levels. Impact and non-destructive testing are not required for PSL-1 pipe.

API 5L pipes are also known as ISO 3183 pipes.
