Double-pressure pipe


Summary

double clamping connection definition:
A connection method in which pipes are connected with socket fittings with special sealing rings, and special tools are used to compress the gates for sealing and fastening.

double clamping connection principle:
Double clamping connection is derived from the mature mainstream technology in Germany. Due to the full use of the effective rigidity of the stainless steel pipe itself, both ends are crimped with calipers at the connection between the pipe and the pipe fitting, thus realizing the surface fixation, double-sided crimping and double protection, thus greatly improving its anti-pulling ability and anti-rotation ability.
The double-clamping pipe adopts the advanced compression ratio principle of O-ring. After the O-ring in the U-groove is compressed, it exerts long-term elasticity, thus realizing the purpose of sealing. In addition, the double-clamping pipe can effectively prevent the risk of water leakage when the pipe cannot be inserted to the bottom due to the advantage of the receiving port.
