Pipe flanges and pipe connections can be divided into five basic types: flange, threaded flange, socket welding flange, loose flange. There are Many kinds of sealing faces for flanges. They usually have convex surfaces (RF), concave surfaces (FM), concavo convex surfaces (MFM), mortise and grooved surfaces (TG), full plane (FF), and ring connection surfaces (RJ).
Flat steel flange
Welding steel flanges for carbon steel pipe for the nominal pressure of not more than 2.5MPa connection, flange sealing surface can be made smooth, bump and tenon slot three. Flat welding flange smooth application of the largest, for mild medium conditions
Under the circumstances, such as low pressure non purification compressed air, low pressure circulating water, its advantage is that the price is cheaper.
Welding steel flanges
Butt welded steel flanges are used for butt welding of flanges and pipes. Its structure is reasonable, its strength and stiffness are large, and it can withstand high temperature, high pressure, repeated bending and temperature fluctuation. Its sealing is reliable. The butt welding flange with a nominal pressure of 0.25 ~ 2.5MPa is Concave and convex sealing surface
Socket welding flange
Socket welding flange used in PN is less than 10.0MPa, DN is less than or equal to 40 in the pipeline.
Loose flange
The loose sleeve flange is commonly known as the live sleeve flange, the live sleeve flange of the welding ring, the flanged live sleeve flange and the butt sleeve flange.
Commonly used in medium temperature and pressure are not high and medium corrosivity is strong. When the corrosive medium is strong, the part of flange contact medium (flanging short section) is corrosion resistant high-grade material, such as stainless steel and other materials, while the outer part is clamped with low grade materials such as carbon steel flange ring to achieve sealing.
The overall flange
The whole flange is often made of flanges with equipment, pipes, fittings, valves and so on. This type is often used on equipment and valves.
