STRAUB CONCEPT - TWO TYPES OF COUPLINGS
STRAUB-METAL-GRIP & STRAUB-GRIP
Pull out resistant STRAUB-GRIP and STRAUB- METAL-GRIP couplings join plain end pipes with axial restraint.
STRAUB-GRIP and STRAUB-METAL-GRIP provide pull out resistance in excess of the coupling’s rated working pressure. Whether for pressure or suction lines, thick
or thin wall pipe, the STRAUB-GRIP and STRAUB- METAL-GRIP couplings are installed quickly, safely and economically. Due to the unique design of the anchor ring, as internal pressure increases, the anchoring effect is progressively increased. The engagement of the teeth into the pipe's outside surfaces provides for electrical conductivity across the pipe joint.
STRAUB-FLEX & STRAUB-OPEN-FLEX
not Pull out resistant
The STRAUB-FLEX coupling will join virtually any plain end pipe, including pressure or suction lines, thick or thin wall pipe.
STRAUB-FLEX coupling is installed quickly, safely and economically. STRAUB-FLEX couplings can accommodate pipe system expansion and contraction movement as well as angular deflection.
Both STRAUB-FLEX & STRAUB-OPEN-FLEX couplings require the pipes to be axially restrained and are an economical alternative to rubber and metal expansion joints.
STRAUB-OPEN-FLEX is a split coupling version of STRAUB-FLEX, offering all the STRAUB-FLEX benefits, plus being able to make repairs to in service pipe
lines. With the coupling, leaks due to faulty weld joints, pitting holes and short cracks can be temporarily or permanently repaired with minimal down time
The split gasket design can be wrapped around the pipe and installed without pipe disassembly. Assembly tools are available to ease the installation of the STRAUB- OPEN-FLEX coupling. When used to join pipe ends
the STRAUB-OPEN-FLEX coupling provides the same flexibility features as the STRAUB-FLEX design.
