Carbon Seamless Steel Reducers
Reducing the diameter of the tube is the same as the diameter of the big diameter tube into the mold, the tube along the axial direction of the press, the metal along the cavity movement and shrinkage forming. Depending on the size of the reducer diameter, divided into a press forming or multiple press forming

High-quality products

Reducing pipe, also known as the size of head, it is a chemical pipe fittings, mainly for two different diameter connections; Concentric reducer mainly has the following characteristics: 1, when the flow of fluid in the pipeline changes, such as increased or decreased, the flow rate requirements change is not, are required to use adjustable tube. 2, into the pump inlet, in order to prevent cavitation. 3, and instruments, such as flow meters, regulating valve joints, in order to join with the instrument joints, also need to use different-diameter pipe.
