High Precision Stainless Steel Pipe Fittings SS316 Concentric Reducer 3 / 4 " To 60"
SS316 Concentric and eccentric reducer are very common in the stainless steel pipe fittings system. They are used to conncet the steel pipe or other fittings with different nominal diameter, so we also call it as reducing fittings. Same as other buttweld fittings, steel pipe reducer has large range of dimensions which cover 3/4" to 60".
We are specializing in industrial pipe fittings for companies who involved in Equipment Manufacturing, Mining, Oil Refineries, Chemical manufacturing, Steel and Aluminum Manufacturing, Utilities and Transportation, and Industrial Construction.
Except the stainless steel pipe reducer, pipe fittings are also in form of Bend, Elbow, Tee, Cap, Stubend, Nipple, Union, Cross, Coupling, Socket, Plug, Sokolet, Weldolet, Thredolet, Elbolet, Nipolet Etc.
