Background:
The butt welding flange is not easy to deform, has good sealing and is widely used. It has corresponding rigid and elastic requirements and reasonable butt welding thinning transition. The distance between the weld junction and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively complex horn shape structure, which is suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, It is generally used for the connection of pipes and valves with PN greater than 2.5MPa; It is also used for pipelines conveying expensive, flammable and explosive media.
Production process
Forging, casting, medium plate turning
Flat welding flange
The connection form is single-sided welding and double-sided nut connection.
The product features beautiful appearance, smooth surface, acid and alkali resistance, anti-corrosion and strong texture performance.
The production process includes cutting materials from the oxygen furnace, forging as a whole or forging and cutting the finished products.
Processing mode: high precision CNC lathe turning, CNC rocker drill drilling
