  API 5L X46 Pipe Specifications

  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.

  API 5L X42 Pipe Specifications

  API 5L X42 pipe has a minimum yield strength of 290 MPA, enabling it to operate in low to medium pressure pipes. These grades of pipe are superior to API 5L Grade B pipe in terms of chemical and mechanical properties. It has higher mechanical strength than API 5L Class B pipe and is therefore less susceptible to cracking. For industrial applications requiring higher strength pipes, customers prefer API 5L GR. X42 pipe replaces API 5L Class B.
