About Stainless Steel 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.

316/316L Stainless Steel

Grade 316 is the standard molybdenum-bearing austenitic grade, particularly higher resistance to pitting and crevice corrosion in chloride environments. It is readily brake or roll formed,welded, soldered and cut by both thermal and mechanical methods.The austenitic structure gives excellent toughness, even down to cryogenic temperatures.Grade 316L, the low carbon version of 316, is highly resistant to sensitisation (grain boundary carbide precipitation) and so is extensively used in heavy gauge welded components (about 5mm and over). Grade 316H, with its higher carbon content has some application at elevated temperatures, as does stabilised grade 316Ti.

316L is actually a stainless steel material, which contains a certain amount of Mo element. The performance of this steel has exceeded that of 301 steel and 304 stainless steel. It has a very wide range of applications. Even in high-temperature environment, it will not be eroded and corroded by high temperature. It can also be used in the marine environment, and will not be polluted by some outer air, resulting in corrosion.
