API 5L GR. X42 ERW steel pipe also called L290 pipe (by ISO 3183), named by minimum yield strength 42100 Psi or 290 Mpa. It’s a higher grade than Grade B where API 5L has various grades up to X100, so API 5L GR.X42 ERW steel pipe is an low-medium level, and it requires large quantities in most of pipelines for oil and gas transmissions.
API 5L GR.X42 ERW steel pipes ranges in PSL1, PSL2, Sour Services, for onshore and offshore.
API 5L X42 PSL1, in common delivery condition of As Rolled.
API 5L X42N/M/Q, for PSL2 pipe with delivery condition of N, M, and Q.
API 5L X42NS/MS/QS, used for sour services pipelines.
ERW stands for Electric Resistance Welded, indicating that the carbon steel pipe is manufactured using a welding process that utilizes electric current to join the steel plates or coils together. X42 ERW steel pipes are commonly used in the oil and gas industry for transporting fluids and gases under high-pressure conditions. They are known for their…
