High-Quality OEM Pipe Joint Coupling Factory Quotes – Style 1GH Heavy Duty Rigid Coupling 500Psi – DIKAI

Product Introduction

•Style 1GH heavy duty rigid coupling provides flexible connection by the gap between pipe groove and coupling key.
•Unique design allows both axial and radial movement,suitable for pipeline with flexibility under intermediate pressure.
•Enhanced body resists 4 times working pressure.

Size Specification:

The Shurjoint Model Z07 is an angle-pad design rigid coupling for general piping applications where rigidity is required including valve connections, mechanical rooms, fire mains and long straight runs. The angle-pad design allows the coupling housings to slide along the bolt pads when tightened. The result is an offset clamping action which provides a rigid joint that resists flexural and torsional loads. Support and hanging requirements correspond to ANSI B31.1, B31.9 and NFPA 13. The Shurjoint Model Z07 is available with a standard “C” shaped or GapSeal gasket in a variety grades to meet your specific service requirements.
