In many pipeline constructions, various typesof fitting are used to connect tubes.In our company, we can provide many types of this product, including elbow(45 °,90° and 180 °),bend, tee and flange, etc.

Elbow and bend are used at the turningpoint of tube. And their radiuses of curvature are different. For elbow, it is1.2 and the value is bigger than 2 for bender. With differentmanufacturing processes, they are used in different occasions. For cold bend,it can be manufactured by line tube and it can be completed by one time withoutsecondary anti-corrosion. But elbow needs to be customized by factory and secondary anti-corrosionis needed so the cycle is quite long. They can all be used in open area andcost is the only consideration. However, for narrow area, bend must be usedsuch as rock tunnel because it has small value of radius of curvature.

Tee is used at the convergence point of three tubes to shunt fluids. Ourcompany can provide many different models of equal type and reducing type.Equal type has the same diameter between main tube and branch tube. Forreducing type, the diameters between them are different so customers can chooseon their actual needs.

The main function of flange is to connect tubes. There areholes on the surface and bolt is used to connect them. According to structure type, this product can be divided into integral type, lapjoint type and threaded type, etc. The main features of this connection areeasy removal, high strength and good sealing performance. When installing products, both ofthem should be parallel to each other to prevent bruiseof sealing surface.
