Low pressure pipeline can use wire stainless steel flange, the use of more than 4 kg pressure welding of stainless steel flange. By sealing point between two pieces of stainless steel flange and bolt fastening. Stainless steel flange have different thickness and different pressure with different bolt.
When, pump and valve and pipeline connection, these local equipment, also made the corresponding stainless steel flange shape, also known as stainless steel flange connection. Where there are two surfaces in the surrounding use of bolt connection closed connection parts at the same time, generally referred to as the “stainless steel flanges,” such as ventilation pipe connections, this kind of parts can be called “stainless steel flange parts”. But this connection is only a partial equipment, such as stainless steel flange and the pump connection, is bad call water pump “stainless steel flange parts”. Relatively small, such as valve can call “stainless steel flange parts”.
Gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials. Most gaskets from non-metallic plate cutting down, or produced by professional factory in accordance with the provisions, the size, the material of asbestos rubber sheet, asbestos board, PE board, etc.; Also useful sheet metal (tin, stainless steel) will be made of asbestos etc. Nonmetal material wrapped metal package cushion; Another with steelskin belt with asbestos tape winding of spiral wound gasket. Ordinary rubber gasket is suitable for the occasion of temperature below 120 ℃; Asbestos rubber gasket suitable for vapor temperature below 450 ℃, the oil temperature is below 350 ℃, pressure is lower than 5 mpa, for general corrosive medium, the most commonly used is acid-proof asbestos board. In high voltage equipment and pipelines, using 10 copper, aluminum, steel, stainless steel type lens or other shaped metal gasket. High pressure washer and sealing surface contact width is very narrow (line contact), processing with gasket sealing surface roughness is higher.
Low pressure small diameter wire stainless steel flange, high pressure and low pressure of large diameter used welding stainless steel flange, stainless steel flange thickness and different pressure connection bolt diameter and the number is different.
