Project Description

Maximum allowable working pressure 5 bar (gas)

Special elongated coupling of special design with integrated safety system Sentry GS, specially designed for convenient operational automatic blocking of gas flow in the pipeline in case of damage to the pipe located in the ground, such as an excavator.

The devices have an original open heating spiral, designed to create optimal heat transfer, they also have a large depth of conjugation, a fairly wide welding area, including the mandatory cold zones located on the sides and in the center, preventing the flow of hot molten mass, do not require special positioners and various devices during operation.

Coupling universal type Z execution optimally satisfies the requirements in relation to working pressure and medium volume flow. Types D and Z have overflow devices. DVGW certified for gas flow control system Sentry GS: DG-4360BO0438.
