What is the difference between high pressure flange and ordinary flange?

One, the difference between high pressure flange and ordinary flange

The pressure that can be accepted by high pressure flange and ordinary flange is different. High pressure flange is used for pressure higher than 10MPa pipeline or equipment connection flange. The pressure is small with plate flat welding flange is more, high-pressure flange is usually the whole flange, with neck flat welding flange, this kind of flange can accept a relatively large pressure.

Two, high-pressure flange: used for pressure higher than 10MPa pipeline or equipment connection flange. At present, it mainly includes traditional high-pressure flanges and high-pressure self-tightening flanges. High-pressure flange is mainly used in the installation of pipelines, high-pressure flange connection is an important connection of pipeline construction, the main connection between the pipe and pipe connection, play an important role and value. High-pressure flange connection is the two pipes, fittings or equipment, first each fixed in a flange, between the two flanges, plus flange gasket, bolted together to complete the connection. Some pipe fittings and equipment has its own flange, also belongs to the flange connection.

Three, high-pressure flange product performance:

1, abrasion resistance: ceramic composite steel pipe lined with ceramic layer in the Al2O3 content of more than 95%, micro-hardness HV1000-1500, and thus has a very high abrasion resistance, and its abrasion resistance than quenched medium-carbon steel is more than ten times higher than tungsten drilling carbide.

2, corrosion resistance ceramic is a neutral material, stable chemical properties, has excellent corrosion resistance and acid resistance, can resist a variety of inorganic acids, organic acids, organic solvents, etc., and its degree of corrosion resistance is more than ten times that of stainless steel. High-pressure flange is mainly used in the place where the pressure resistance is relatively strong. Generally above 10 pressure, called high pressure.
