Hebei flange,

Carbon steel high pressure butt welding flange is a kind of pipe fittings, which refers to a flange with a neck and a round pipe transition and butt welding with the pipe. Carbon steel high-pressure butt-welding flanges include many types and models. Butt-welding steel flanges are used for butt welding between flanges and pipes. They are mainly used in welding technology. They have good use characteristics and performance, and their structure is reasonable. The rigidity is greater.
Scope of application of carbon steel high pressure butt welding flange:
butt welding flange is not easy to be deformed, good sealing, wide application, corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition, the distance between the welding port and the joint surface is large, and the joint surface is free Due to welding temperature deformation, it adopts a more complicated horn-shaped body structure, which is suitable for pipelines with large fluctuations in pressure or temperature or high temperature, high pressure and low temperature pipelines, and is generally used for the connection of pipelines and valves with PN greater than 2.5MPa; also used It is used on pipelines that transport expensive, flammable and explosive media.
Carbon steel high pressure butt welding flanges, neck flat welding flanges, socket welding flanges and threaded flanges are generally made by forging or forging and rolling. When carbon steel high pressure butt welding flange manufacturers use steel plates or section steels , Meet the following requirements:
1. The used steel plate should pass the inspection standards before use. The steel plate should be ultrasonically inspected without delamination defects to ensure the quality and performance of production and processing.
2. It should be cut into strips along the rolling direction of the steel. Shaped, butt-welded into a circular ring by bending, and the surface of the steel is formed into a cylindrical surface of the ring. Steel plate shall not be directly machined into a necked flange.
3. The butt weld of the circular ring shall be a full penetration weld.
4. The butt weld of the ring should be subjected to post-weld heat treatment and radiographic or ultrasonic inspection. The radiographic inspection meets the requirements of JB4730 Class II, and the ultrasonic inspection meets the requirements of JB4730 Class I...
