Coupling Joints

WCB STEEL CASTING TO ASTM A216 Female/Male Couplings

In striving for greater joint performance as well as improving cost competitiveness Helicast™ has engineered a rationalisation of the Helicast™ coupling range, with a combination of old and new designed couplings.

To simplify nomenclature the couplings are now know by the prime pipe diameters that the couplings connect. This is ensuring that the correct coupling is specified.

Current Range:

Series 150 Male and Female couplings

Couplings primarily designed for 76.1 and 88.9 OD pipe shafts. They have been used with light wall 114.3mm OD pipe but if used with heavier pipe and higher install torques coupling failure may occur within joint.

Series 280 Male and Female couplings

Couplings primarily designed for heavier walls in 88.9mm OD and all wall thickness of 114.3mm OD pipe. These couplings are cost effective for those pipe diameters and heavier wall thickness.

Series 350 Male and Female couplings

Couplings primarily designed for all wall thickness of 168.3 and 177.8 mm OD pipe. Can be adapted up to 219.1mm pipe Diameter in an emergency, but joint likely to fail if taken beyond 100,000 Nm install torque.

Series 450 Male and Female couplings

Couplings primarily designed for 219.1 mm Dia x 12.7mm wall thickness and below are capable of handling to 150,000 Nm installation torque these couplings may be increased in shaft size capacity to 273x 9.3mm maximum pipe size by using the 219/273 cast pipe adaptor ring.
