Reducing pipe is one of the chemical pipe fittings, used for connecting two different pipe diameters. Again divide into concentric size head and eccentric size head.

The materials of reducing pipe include stainless steel reducing pipe, alloy steel, carbon steel size head of reducing pipe, 20 steel q234Q345 of reducing pipe, etc.

The roundness of the reducing pipe shall not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation shall be ±3mm. The materials of reducing pipe are SY/T5037, GB/T9711, GB/T8163, American standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements standards

Reducing pipe (size head) is a pipe fitting used for reducing the diameter of a pipe. The usual forming process is reducing pressing, expanding pressing or reducing and expanding pressing, and stamping can also be used for reducing pipe of some specifications.
