The sealing principle of the 316L stainless steel plate flanging flange: the two sealing cover of the bolt extrude the flange gasket and form the seal, but this also causes the sealing to be destroyed. To keep the seal tight, it must maintain a large bolt force. For this purpose, the bolt must be larger. Larger bolts match larger nuts, which means larger bolts are needed to create conditions for tightening nuts. However, the larger the diameter of the bolt, the applicable flanges will become bent, which is to increase the wall thickness of the flange.

The 316L stainless steel plate flat welding flange is generally not easy to deform, has good tightness, and is widely used. Carbon steel flanges are an effective sealing pipe, which requires 50% of the bolt load to be used to squeeze the gasket, while only 50% of the load is used to maintain the pressure.

316 l stainless steel plate flat welding flange, including a variety of types and model's butt welding steel flange and pipe flange is used for welding, mainly used in welding technology, the use of good characteristics and performance, its structure is reasonable, the strength and stiffness is bigger, can withstand high temperature and high pressure curve and temperature fluctuation, and repeated the sealing is reliable, nominal pressure of 0.25 ~ 2.5 MPa rolling flange with concave and convex type sealing surface. Flat welding flange is a kind of flanges, which is widely used and popularized in the mechanical industry. Rolling flange of the wide range of USES, use scope according to the characteristics of different, more than in the mild conditions of medium, such as suit low circulating water, the purification of compressed air, and it has the advantage of the price is cheaper.

The 316L stainless steel plate flat welding flange is generally not easy to deform, has good tightness, and is widely used. Carbon steel flanges are an effective sealing pipe, which requires 50% of the bolt load to be used to squeeze the gasket, while only 50% of the load is used to maintain the pressure. About carbon steel flange of the problem has been more attention topic, it is related to the production cost of companies and enterprises, or economic benefit, so about carbon steel flange sealing principle is constantly improved and perfected. The sealing principle of carbon steel flange: the two sealing surface of the bolt extrude flange gasket and form seal, but it also causes sealing damage. To keep the seal tight, it must maintain a large bolt force. For this purpose, the bolt must be larger. Larger bolts match larger nuts, which means larger bolts are needed to create conditions for tightening nuts. However, the larger the diameter of the bolt, the applicable flanges will become bent, which is to increase the wall thickness of the flange.
