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

Stainless steel also contains varying amounts of Carbon,
Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
