2A14 Aluminum Nylon Coated Plate Flange Sop-Ff JIS Non-standard Cover Plate And Blind Flange

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, it can be called as flange type parts.

From the perspective of composition, 2A14 belongs to the hard aluminum alloy and is a forging aluminum alloy. Compared with the 2A50, because the copper content is high, the intensity is high and the heat is better, but the plasticity in the heat is not as good as 2A50. The alloy is not as good as 2A50. It has good cuttings, good contact, welding, and roll welding performance, and poor arc welding and gas welding performance; heat treatment can be enhanced, and there is a squeezing effect; the corrosion resistance is not high, and there is a tendency to corrosion of the test in time.
