Features of Casing Pipe:


1) Use optimized buttress thread so that the connecting strength can reach the strength of the pipe body.

2) High seal reliability: this product has the multi-seal configuration.

3) The joint has high capability to resist compression, bending and over-torque load with the reverse torque internal shoulder.

4) Energy loss reduction: the air and liquid turbulence are reduced by the inner flat design.
