API 5L X42 PSL2 SAW 3PE Anti-corrosion spiral welded steel pipe

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.
