Directly buried type corrugated pipe is introduced
Directly buried type of corrugated pipe is mainly used for buried pipeline axial compensation, with bending ability. Is mainly suitable for axial compensation, at the same time, it has strong bending ability, so don't consider the effect of pipe sinking, direct buried bellows compensation frame and guide sleeve to protect the free expansion compensation, other properties with the ordinary corrugated pipe is the same.

Direct buried bellows installation considerations
To make direct buried bellows compensation effect, must set a fixed bracket on both ends of the corrugated pipe, prevent pipe affected by internal pressure thrust outward stretch.
One end of the bellows (one-way compensation of directly buried bellows dead end) is near the end of a fixed bracket, with live head of bellows compensation pipeline.
Set the distance of the two fixed bracket according to the amount of compensation, compensation amount is generally not greater than the pipe diameter.
Pressure test with corrugated pipe may not appear in the process of drawing.
Products can be customized according to customer's requirements.
