Steel Pipe Fittings

Pipe fittings are a general term for the components that play a role in connecting, controlling, changing direction, diverting, sealing, supporting, etc. in pipeline systems.The fittings used for interconnecting pipes include flanges, unions, pipe clamps, clamps, sleeves, throat clamps, etc.Pipe fittings that change the direction of pipes: elbows, bends.Pipe fittings that change the diameter of pipes: variable diameter (reducing pipe), reducing elbow, branch pipe platform, reinforcing pipe.Add fittings for branching pipelines: tees.Pipe fittings used for pipeline sealing: gaskets, raw tape, hemp thread, flange blind plates, pipe plugs, blind plates, heads, welding plugs.Pipe fittings used for pipeline fixation: snap rings, drag hooks, lifting rings, brackets, brackets, pipe clamps, etc.
