Pipe Infrastructure Capabilities


The appointed piping installer is a hydraulic plumbing contractor who specialises in large scale residential and commercial construction projects. Allmach provided the installer with approximately 10km of 316L Surepress stainless steel pressfit pipe and fittings ranging from 15mm to 168mm. Due to the volume of water and gas required, 168mm pipework was installed for the cold water and gas feedlines. To save on-site installation time, custom fabricated manifolds and spools were installed in the pump room and prefabricated manifolds installed in the meter cupboards. In addition, 15-degree bends were supplied for piping offsets and M10 zinc rubber insulated pipe clips and powder coated strut clips for the pipe support. The piping systems installed cover gas, hot and cold water, and recycled water supply throughout the development.


Challenges and Solutions


Allmach worked with the installer for a 2-year period to overcome some key challenges including widely fluctuating supply and pricing of piping, and the critical shortage of labour during the pandemic. As Surepress pressfit piping systems are 10 times faster to install than traditional piping, the system contributes to a 30% reduction in installation costs. Other factors contributing to the speed of installation include no welding labour, hot work permits, special tooling or post treatment required. In addition, the cellophane check sleeve, designed to fall away after each successful press, makes the QA checks quick and simple.
