Butt welding flange is a kind of pipe fitting. Butt welding flange is also called split flange, which refers to the flange with neck pipe and round pipe transition and butt connection with the pipe. Flanges are components that connect pipes to each other and to the ends of pipes. There are holes in the flange, and the bolts make the two flanges tightly connected. Welded flanges and their gaskets and fasteners are collectively referred to as flange joints. Flange joints are an essential part of equipment and equipment components, as well as pipe design, pipe fittings and valves.
Applicable scope of welding flange:
It has corresponding rigidity and elasticity requirements, is not easy to deform, has good sealing performance, and is widely used. Reasonable butt weld thinning transition. The distance between the joint and the joint is large, and the joint has no temperature deformation after welding. It adopts a complex bell-shaped structure, which is suitable for pipelines with large pressure or temperature fluctuations or pipelines with high temperature, high pressure, and low temperature. It is generally used for the connection of pipelines and valves with PN greater than 2.5MPa. Butt welding flanges can also be used to transport expensive flammable and explosive materials in the pipeline of the medium.
The use of welding flange:
Flanges are mainly used for pipe connections. Various flanges are installed on the pipes to be connected. Threaded flanges can be used for low pressure pipes, and butt welding flanges can be used for pressures above 4kg. Add a gasket between the two flanges, and then tighten it with bolts. The different bolts used mainly depend on the thickness of the butt welding flange under different pressures. When pumps and valves are connected to pipelines, the parts of these devices are also made into corresponding flange shapes. Also known as flange connection. All connecting parts bolted and closed on the outside of the two planes are usually called "flanges". Welding flange shall be marked according to nominal diameter, nominal pressure, sealing surface form code, designated steel pipe series code and standard number.
Butt welding flanges have different production specifications in use and production. According to the corresponding specifications, the practical application value and effect of the butt flange can be guaranteed. Large-scale applications of high-pressure butt welding flanges: boilers, pressure vessels, petroleum, chemical, metallurgy, machinery, food and other industries.
