Everyone knows that sae flange is an indispensable part in the pipeline system and occupies an unshakable important position in the whole pipeline system We also know that flanges can be used in conjunction with flange gaskets and flange bolts to form detachable joints to connect static pipes to rotating or reciprocating equipment, so let's learn about the use of sae flanges.

Sae flangeparts that do not serve as connections in piping systems but connect shafts to shafts are used to connect pipe ends In addition, there are flanges that facilitate the inlet and outlet of equipment used for connecting two equipment, such as reducer flanges Anyway, the function of flanges is to connect, but what we don't know is that the function of flanges is not only to connect, but also to position.

Just give an example, such as the installation of the cylinder Four symmetrical holes are opened around the cuboid, and a large hole in the middle is the same as the outer diameter of the cylinder, so that the cuboid can be sleeved on the cylinder and welded and fixed together The connection between the cylinder and other things is connected by four holes around this cuboid This cuboid is called a flange This installation method of the cylinder is called flange installation So the function of the flange here is to position Actually, it's what we said & ldquo; Fixed & rdquo; 。 That is to say, the positioning function of flange is the fixing function of flange That is to say, do you understand the positioning function of flange?

Main functions of sae flanges: gaskets are rings made of plastically deformable materials with certain strength. Most gaskets are cut from non-metallic plates or manufactured by specialized factories according to specified sizes The material is asbestos rubber board, asbestos board, tetrafluoride board, polyethylene board and other metal gaskets made of non-metallic materials, as well as metal-clad gaskets wrapped with non-metallic materials such as asbestos

Sae flangeThere are also spirally wound gaskets composed of thin steel strip and asbestos strip. Common rubber gaskets are suitable for below 120. Asbestos rubber gaskets are suitable for water vapor temperature below 450. Acid-resistant asbestos plates commonly used in corrosive media when oil temperature is lower than 350 and pressure is lower than 5MPa. High-pressure equipment and pipelines are made of copper-aluminum No.10 steel and stainless steel. The high-pressure gaskets have very narrow contact range with the sealing surface (line contact) and the sealing surface

Low-voltage small-diameter wired sae flanges high-voltage and low-voltage large-diameter flanges use welded flanges Thickness of flange, diameter and number of connecting bolts vary according to pressure Large flanges General integral flanges have flat welded flanges and butt welded flanges The stiffness difference of flat welded flange is suitable for the situation of pressure p4MPa Butt welded sae flange is also called high neck flange with high rigidity, which is suitable for the occasion of high stress temperature of press-in fixed flange There are three types of flange sealing surfaces. Flat sealing surfaces are suitable for occasions where the pressure is not high and the medium is non-toxic; Suitable for concave and convex sealing surface when the pressure is slightly higher; The sealing surface of tongue groove is flammable and explosive, which is suitable for toxic medium and high pressure occasions Sae flange joints with different properties have good product performance in different fields and will produce different effects in different applications and spaces

Sae flange cut the large flange and the middle plate into slats and process them into circular waterline bolt holes, etc. Usually this is a large flange up to 7 meters. This flange is of good quality because the material is high density medium plate
