Connecting pieces for tubes

Our products

Product category: Connecting pieces for tubes

UNI-Flex

UNI-Flex pipe couplings are used for connecting restrained pipes. Both metal and plastic pipes can be connected safely and quickly and the coupling range is a high performance product range that allows pipe angulation, expansion and contraction.
With UNI-Flex pipe couplings sealing reliability is also ensured under the condition of gaps between pipe ends that are compensated.

UNI-Flex couplings are a popular choice of water authorities, civil engineers and building contractors and they are available in sizes from 0.84 mm up to and including 157.48 mm in diameter.

The stainless steel and high strength steel designs of the UNI-Flex coupling range ensure significant weight savings are achieved over cast iron couplings. This results in less manpower, quicker installation times and massive cost savings.

UNI-Rep

UNI-Rep couplings are non-restraint repair couplings. They are used to connect and/or seal damaged metal and plastic pipes. Featuring “cut flanges” on the underside of the fitting, this type of coupling can be easily pulled around a leaking pipe to seal a fracture. Once wrapped around the pipe, the fitter then goes about installing the coupling in the same manner as any other UNI-Coupling model. They enable repairs to be carried out easily, quickly and safely without the need to dismantle the pipes.

The UNI-Rep couplings are suitable for emergency repairs in buildings and industrial units to avoid costly reinstatement work caused by water damage. The UNI-Rep couplings represents excellent value for money both at point of order and at point of use, as significant installation time saving can be achieved with the light-weight stainless steel design.

UNI-Grip

Axial Restraint Coupling

The UNI-Grip pipe coupling is designed to replace the need for flanging, welding, pipe grooving and pipe threading by providing a quick and easy solution to joining plain-end pipe. This is possible due to the anchoring ring with conically stamped teeth that indents into the pipe’s surface (steel, stainless steel or cast iron) and provides safe and strong axial restraint.

The UNI-Grip’s special teeth design with progressive anchoring effect with ball solution offers high levels of security by locking the pipes together under pressure.

When the axial tensile load of the pipe is increasing by internal pressure or external influence, specially shaped balls brought in at the back will push hardened teeth into the pipe surface. The depth of the anchoring’s teeth under pressure is approximately0.003 inch to 0.01 inch.
With the use of this method it is possible to achieve improved anchoring behavior on hard surfaces like thin-walled stainless steel or cast-iron pipes. By the oblique angle of the teeth, anchoring is obtained by coated surfaces like hot dip galvanized steel tube.

Not only the teeth are innovative. The UNI-Grip’s gasket solution is patented and uses the latest techniques in sealing. During installation of the coupling compensation beads/grooves are used, therefore the stainless steel insert that is needed in gaskets used by competitors is no longer needed what solves the corrosion problem that comes with these strip inserts. The strip insert is now only needed in vacuum pipes.

The UNI-Grip pipe coupling is available in ranges from 0.82 inch up to including 29.52 mm. All models are suitable for new installations and retrofit, whether on a building, ship or process plant. The UNI-Grip range offers a pipe coupling system that accommodates angulation, vibration and vacuum.
