STRAUB-METAL-GRIP

STRAUB-METAL-GRIP pipe couplings are axially tension-resistant pipe connections for all metallic pipes and rigid plastic pipes. The universal connection solution offers countless application possibilities on almost all pipe systems. The installation is carried out on smooth-surfaced pipes without any pipe end machining. The compact design allows pipe routing in the smallest of spaces. Unexpected secondary stresses, as well as inaccuracies in the pipe routing caused by the customer, are absorbed by the couplings due to the flexible design. This allows a simple and quick installation, which results in noticeable cost savings.

Remarks:
- Follow fitting instructions
- PN (Industry) = working pressure considering the application loads
- Test pressure = PN (Industry) x 1.5 (for example industry, water supply etc.)
- PN (Shipbuilding) = nominal pressure, includes four times safety factor (e.g. shipbuilding)
- The pressure values are valid on radial rigid carbon steel pipes under static loads
- Strip inserts are optional accessories
- Additional sealing sleeves and temperature ranges on request
