High pressure flange is mainly used in the installation of pipeline. High pressure flange connection is an important connection mode in pipeline construction. The connection between main connecting pipe and pipe plays an important role and value.
High pressure flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pads, bolted together to complete the connection.
Some pipe fittings and equipment already have their own flange, but also belong to the flange connection.
[1] High pressure flange product performance:
1. Wear resistance: the content of Al2O3 in the ceramic layer of ceramic composite steel pipe is more than 95%, so the microhardness HV1000-1500, has extremely high wear resistance, and its wear resistance is more than ten times higher than that of quenched medium carbon steel, which is better than that of tungsten drill cemented carbide.
2. Corrosion-resistant ceramics are neutral materials with stable chemical properties, excellent corrosion resistance and acid resistance, resistance to various inorganic acids and organic solvents, and their corrosion resistance is more than ten times that of stainless steel.
