REDUCER（Concentric,Eccemtric,with Hem,without Hem）

Concentric & Eccentric Reducer

Reducer has different diameters at both ends and are used to connect pipes or flanges of different diameters for diameter changes. There are two types of products: concentric reducers and eccentric reducers. The two ends of concentric reducers are centered on the same axis and are generally used for reducing the diameter of gas or vertical liquid pipelines. Eccentric reducer with inner circumferential cutting at both ends of the pipe mouth, generally used for horizontal liquid pipelines to prevent liquid accumulation while reducing diameter
we are manufactures,suppliers and exporters of concentric reducers, a type of pipe reducer that fastens pipe sections on the same axis and is conical in shape.he usual forming process is reduction pressing, expansion pressing or reduction and expansion pressing. Stamping forming can also be used for some specifications of different diameter tubes.
these pipe fittings have varying ends and can join unequal diameter pipes on different pipe sections falling on the same axis.

Our Quality

Our Quality Management System has been certified to ISO9001 to gurantee all production processes are controlled so as to insure that all materials are traceable and only the highest quality material are delivered to the customer

All materials are tested by destructive and non-destructive testing methods which are performed at various stages in the production process according to quality plans

Non-destructive tests:

Ultrasonic test
Radiographic examination
PMI test
Penetration Test
Dimension examination
Surface examination
Hardness Test

Destructive tests:

Metallographic examination
Intergranular corrosion test
Grain size test
Mechanical property test
Tension test
Bending test
Impact test

◆ We will ensure the thickness of the back of elbow, do not cut corner.

◆ We will never use 304 instead of 304L for pipe fittings made of 304L.

◆ Pipe fittings surface takes sandblasted, so the surface will be more beautiful.
