Special High-Pressure Flange For Chemical Plants

Special high-pressure flange for chemical plants, high-pressure flange connection is to fix two pipes, fittings or equipment on a flange plate first, between the two flanges. Add flange pads and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections. High pressure flange product performance: Wear resistance: The Al2O3 content in the ceramic layer of the ceramic composite steel pipe lining is greater than 95%, and the microhardness is HV1000-1500, thus it has extremely high wear resistance. Its wear resistance is more than ten times higher than that of quenched medium carbon steel and better than tungsten carbide. Corrosion resistant ceramics are neutral materials with stable chemical properties and excellent corrosion and acid resistance. They can resist various inorganic acids, organic acids, organic solvents, etc. Their corrosion resistance is more than ten times that of stainless steel. High pressure butt welding flange refers to a flange with a neck and a circular pipe transition, which is connected to the pipe by butt welding. Welding flanges are produced and used according to certain principles and principles to ensure that they can be used in the correct way and provide good value and function. Welding flanges are suitable for pipelines with significant pressure or temperature fluctuations or pipelines with high, high, and low temperatures.

It is also used on pipelines that transport expensive, flammable, and explosive media. Welding flanges are not easily deformed, have good sealing, and are widely used. The nominal pressure PN is around 16MPa. The docking size of flanges changes with nominal pressure, resulting in the inability to dock equal diameter flanges. Practical work such as ordering, manufacturing, storage, installation, maintenance, etc. is very complicated. For 0.0.6MPa flanges, a docking size of 1.0MPa is used, and the thickness is still the same as the original three specifications, thus achieving the simplification of docking size. The production standard for high-pressure butt welding flanges: Due to the different specific dimensions represented by the nominal diameter of the container cylinder and the nominal diameter of the pipe, container flanges and pipe flanges with the same nominal diameter also have different dimensions and cannot be used interchangeably. In addition to flat welding and butt welding flanges, there are also cast steel flanges, cast iron flanges, loose fitting flanges, threaded flanges, and other types of pipe flanges.
