Galvanised Shouldered Couplings
Buttweld Fittings
Advanced Piping shouldered clamps are manufactured from quality cast iron, then hot dip galvanised to provide longevity in their typical environment, which includes being dragged around a coal long wall, gold decline, or a dewatering bore on an open cut mine. The couplings final dimensions are very critical to connecting and sealing the two shouldered ends. For this reason, the Advanced Piping shouldered couplings are wax cast, which gives near-perfect dimensional tolerance. Wax cast couplings are far superior to sand cast or pressed metal couplings. Each coupling comes with an active Buna Nitrile (NBR) seal, which is an active seal designed to tighten as the pressure increases. NBR is suitable for potable water, has excellent resistance to fuel and oils, and has a working temperature range of -35°C to + 120°C. The couplings can be recycled many times so the seals/gaskets are available as a spare if required. The 50-355mm couplings have two plated bolts, and larger sizes from 400-630mm have 4 bolts.
