Poly transition fittings are made by moulding a HDPE spigot over the copper, steel, plastic or stainless steel coupling, providing a transition in pipe material to HDPE pipe. PE transition fittings for HDPE pipe come in many different types and sizes, and for many applications. HDPE BSP Fittings are used to join a pipeline to a tank or vessel, or to transition from poly pipe to copper pipe. Female BSP threaded adaptors can be supplied with a steel retaining ring in larger sizes. Threaded long spigot adaptors can be electrofusion welded or butt welded to a pipeline. Short spigot threaded adaptors can only be butt welded. Copper pipe gas adaptor fittings are available from 20 mm to 63 mm. A PE – copper transition fitting has a moulded PE fitting that transitions to a copper pipe end. This allows a seamless transition from HDPE gas pipe and copper gas pipe, without having to use brass screw fittings.
The PE-to-steel roll groove adaptor can save time and money, by transitioning from HDPE Pipe to roll groove steel in one fitting. This saves using two flanges, a gasket and 8 bolt sets, and a lot of tightening and checking by the operator. The roll groove steel adapter works well for fire hydrant and booster connections, and is available in 125 mm (4″) & 180 mm (6″) PN16, SDR11.
