All Size And Standerd Blind Carbon Steel Flange
Product Description:
Flange is the parts which connects two pipe ends, flange connection is defined by the flange, gasket and bolt three are connected as a group of combined sealing structure of the detachable connection. The gasket is added between the two flanges and then fastened by bolts. Different pressure flange, thickness is different, and the bolts they use are different, when pump and valve connect with pipe, the parts of the equipment are also made of the corresponding flange shape, also known as flange connection, usually closured bolted connection parts are also known as flanges, such as the connection of ventilation pipe, this kind of parts can be called "flange type part", but this connection is only part of a device, such as the connection between flange and water pump, it's not inapposite to call water pump as flange type parts,but relative small valve.
There have been more than ten years of production and operation. It's really not much money to make flanges. The biggest impact is the cost of materials. We all choose high-quality materials to produce. Valves are used in very critical places. If there is a problem, oil leakage may occur. Therefore, our requirements for quality are very high. This is why we can produce flanges in Wenzhou for more than ten years.
