Universal Wide Range Couplings & Adaptors
Thomas Unifit universal pipe couplings are designed to accommodate plain ended pipes with different outside diameters. One fitting is able to connect a wide variety of pipe materials including steel, ductile iron, PVC, cast iron, GRP and asbestos cement pipes, amongst others. The range is designed and manufactured under a strict quality management system and the products meet the requirements of SANS 1808-2 of the South Africa Bureau of Standards. All products in the range have a test pressure of 24bar on water (9bar on gas) and are suitable for 16bar working pressure for water (6bar on gas). Higher pressures up to 64bar are available on request.
Longer barrels, higher pressures, different coatings, special stainless steels and specialized rubber compounds are some of the non-standard components available. We are able to design and manufacture special couplings according to customer requirements.
An extensive range from DN15 mm – DN700mm exists for:
– Couplings & Long Barrel Couplings
– Universal Drilling & Steel Flange Adaptors
– Step Couplings
– End Caps and End Plugs.
For joining plain ended pipes of similar or dissimilar materials, UNIFIT Universal Couplings have wide sealing tolerances ensuring all popular pipe materials can be connected. From DN40 - 700mm.
For joining flanged pipeline components to plain ended pipes, UNIFIT Universal Flange Adaptors have wide sealing tolerances and a universal flange drilling to suit T1000/3 & T1600/3. From DN40 to DN300mm.
UNIFIT Long Barrel Couplings are designed specifically for the connection of GRP & HDPE pipe. Barrel lengths are specified to cater for HDPE expansion & contraction upon installation.
UNIFIT Step Couplings are used for connecting pipes of different nominal bore and different pipe material. From DN40 - 3000mm. Restraining cleats and harnesses can be provided to prevent step couplings moving. Double bolt sets are available for GRP pipe.
External Test Caps
UNIFIT External Test Caps are suitable for all rigid pipe materials. Sockets for pipe testing can be added as required. Sizes from DN40 - 600mm. Internal test plugs can be manufactured.
HALF COUPLINGS are supplied for welding to mild steel fittings from DN40 - 600mm. Enabling socketed fittings to be manufactured for all rigid pipe materials catering for pressure ratings up to and including PN64.
S P E C I A L S are avai lable. Customers can specify special materials for bolts, rubbers seals, sleeve and end rings. Higher pressure ratings are available up to 64bar. Special corrosion protection coatings and dimensions can be made to order for all products.
