Our Methane drainage and spiral welded pressure pipe is manufactured from mild steel with ends prepared prior to having each length hot dip galvanised. End preparation can be offered to your requirement as flanged, shouldered or roll grooved and can be manufactured up to 12 metres in length. Spiral welded pressure pipe can be used for air or water supply applications as well as methane drainage in underground mining operations in addition to use as concrete pumping pipework on construction sites. We can also offer a wide range of associated welded and galvanised fittings including bends, tees, reducers and transitions as well as the option for spooling of pipe and fittings if preferred thereby minimising costly on-site fabrication and installation time.
