Urban water supply and drainage flat flange and slip on flange

Urban water supply and drainage flat flange and slip on flange

Application

Flanges are widely used in chemical, petrochemical, food, water supply, natural gas pipelines and other urban water supply and drainage, public pipeline and other professional, submarine pipeline and emerging industry wind power flange industry. Therefore, flange became indispensable accessory products. Flange blank is made, and then the flange blank finishing, so the processing cost depends on the accuracy of flange blank. At present, the main production flange blank by casting molding, casting forging molding, forging, cold roll forming and cutting molding etc.

Advantage

Flange hot rolled process and traditional production process compared with the following advantages:

Hot rolled coil can be a complete, stable quality;

It can be round and curly, fast and efficient.

High precision, good flatness and high yield.

The specifications can be adjusted according to the customer's needs.

Save raw materials, solve the problem of straight section of head and tail, improve the utilization ratio of raw materials, and the new developed convex flange products save about 24% of raw materials compared with traditional technology.

Energy saving and consumption reduction, the new technology and the traditional process compared with the production of each ton flange, can save 60% of coal consumption, electricity consumption of 40%
