The high-quality pipe connect ion

“Pull-out” resistant pipe connections for shipbuilding and the offshore

oil industry.

The GRIP-Z  is a high-performance coupling. It has all

the properties and advantages for the exceptional demands of navalshipbuilding.

• For all marine pipe systems, DNV/GL AND CCS tested

• Also reliably joins CuNiFe, duplex or titanium pipe materials

• High safety factor for unexpected secondary stresses at sea

• Absorbs stresses in the pipe system and during operation

• Minimal bolt torque to optimise seal life

• The mechanically supported sealing lips allow higher thermal

stress variations

• Special steel bridge design with locking part relief

• Separate independent anchoring and sealing mechanisms

• A sealing lip spring supports the sealing sleeve function

• Strengthened casing and locking part

• Particularly suitable for critical safety and operating systems

 

Operating pressure in shipbuilding: 16 bar, offshore 20 bar

Diameters: 30.0 to 168.3 mm

Temperature range: -30° C to 100° C

Order example: GRIP-Z  76.1MM, NBR

Our quality products – your benefit

The results of various endurance tests and inspections prove it and our customers’ satisfaction around the whole world reflects it every single day – GRIP pipe couplings can be trusted. They offer immense customer benefit, convince through practice-tested safety and consequent cost-effectiveness.

System independence: Connects the most varied pipe materials

Flexible pipe connection: Stress-free, compensates for tolerances

Easy assembly: Light, space-saving, no pipe-end preparation

Safe assembly without risk of fire or explosion: No protective measures required

Damping characteristics: Noise, vibration, movement

Economical: Cost-saving thanks to short assembly times

Progressive sealing effect

If the pressure in the pipe rises, the contact pressure on the sealing lips also

increases due to the flow through the pressure equalization channel.

Progressive anchoring effect

If the axial tensile load on the pipe rises due to increased internal pressure or

external influence, the teeth continuously penetrate deeper into the surface of

the pipe to compensate.
