Ductile Iron Fittings
The complete system.
Alongside our full range of pipe we have an extensive range of fittings to provide a complete system. Available from diameters of 80mm through 2200mm we can offer both standard and restrained socketed fittings along with PN16 rated flange fittings as standard.
All of our fittings are suitable for both potable and waste water networks meetings the standards of EN545 & EN598 and also carrying DWI approval.
Technical
-
As standard all our fittings are coated both internally and externally using fusion bonded epoxy.
Fusion Bonded Epoxy (FBE) coating, provides excellent corrosion protection and long-term durability for ductile iron pipes. The FBE coating creates a tough, resilient barrier that protects the pipe surface from corrosion, abrasion, and mechanical damage.
-
Where ground conditions require we can also coat our fittings in PU.
Polyurethane (PU) coating, provides superior corrosion protection and long-term durability for ductile iron pipes, even in the most demanding environments. The PU coating forms a seamless barrier that effectively protects the pipe surface from corrosion and abrasion.
-
Our Ductile Iron Fittings are available in sizes of 80mm through to 2200mm as standard. They can be fully flanged or fully socketed, or a combination of both.
For our restrained system we supply a complete restrained system from diameters of 100mm through to 1800mm.
Jointing Details
-
Our Ductile Iron Fittings use socketed joint with a vulcanized rubber gasket: a hard “heel” for grip and soft “bulb” for sealing. The tapered spigot presses evenly into the gasket, leaving a gap for deflection and thermal expansion, ensuring flexible, durable, and continuous pipeline assembly above or below ground.
-
Flange joints are rigid joints that are mechanical connected to our flanged pipework, valve and hydrants or other fittings. These non flexible joints are designed for unburied applications.
-
Double chamber restrained fittings are socketed fittings designed to connect individual pipes via a locking system. This type of Joint provides restrains against axial movement of pipe systems with the use of lock segments, which are restrained by the socket sloping face and weld bead. Locking segments are placed along the periphery of the pipe spigot and tightened by wrapping belt.
-
Anchor gaskets, with metal inserts are used in this type of joint. The metal teeth allow the spigot to be pushed into the socket. However, once the spigot is fully inserted, the teeth hold the spigot and restrict it from coming out.
