Carbon steel high pressure flange

Carbon steel high pressure flanges for piping or equipment connected flanges with pressure above 10MPa. At present, it mainly includes traditional high pressure flange and high pressure self-tightening flange.

Features of carbon steel high pressure flange:

1. The sealing principle belongs to plastic deformation;

2. Bolt connection;

3. The bolt shall be subjected to tension and temperature difference stress, and shall bear many additional stresses such as bending moment and torque.

4. It is bulky, heavy and difficult to install.

5. The sealing performance is unstable, especially in severe cases, which can produce leakage and have serious consequences.

Application and characteristics of carbon steel high pressure flange:

Carbon steel high pressure flange is mainly used in pipe installation, high pressure flange connection is an important connection mode of pipeline construction, the main connection between the tube and pipe connection, play an important role and value. High pressure flange connection is the two pipes, fittings or equipment, fixed on a flange, a first between the two flange, and flange pad, bolt fastening together, complete the connection. Some pipe fittings and equipment already own flanges, also belong to flange connection.

Performance of carbon steel high pressure flange:

1, abrasion resistance, ceramic composite steel pipe lined with porcelain layer of Al2O3 content is more than 95%, micro hardness HV1000-1500, and therefore has a very high wear resistance, its wear resistance more than 10 times higher than the medium carbon steel after quenching and is better than that of tungsten carbide drill.

2, the corrosion resistance of ceramics is a neutral material, stable chemical performance, excellent corrosion resistance and acid resistance, can resist various inorganic acid, organic acid, organic solvents, such as its resistance to corrosion is stainless steel is more than ten times.
