There is a close relationship between casing pressure and oil pressure.

The biggest difference between open-end and closed-end pipe pile is only one thing.

Casing pressure is the pressure exerted by the surface on the casing inside the well.

Pipe piles are a common foundation construction method used to increase bearing capacity in areas with weak soil or complex geology.

This article will introduce the technical requirements of steel casing, including material requirements, dimensional requirements, mechanical performance requirements, etc.

When building steel pipe piles, reinforcement is often required, so people will think of pouring cement.
