What does API 5L X42 mean?
API 5L X42 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 x42 pipe is an low-medium level, and it requires large quantities in most of pipelines for oil and gas transmissions.
