ANSI DIN Standard A105 Carbon steel flat welding flange
Description
Carbon steel flat welding flange is not easy to deform, has good sealing and is widely used. It has corresponding rigidity and elasticity requirements and reasonable flat welding thinning transition. The distance between the welded junction and the joint surface is large, and the joint surface is free from welding temperature deformation.

Characteristic
Carbon steel flat welding flange adopts a complex trumpet structure, which is suitable for pipelines with large fluctuation of pressure or temperature 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; It is also used for pipelines conveying expensive, flammable and explosive media.
Application
Carbon steel flat welding flange is mainly used in boiler and pressure vessel, petroleum, chemical industry, shipbuilding, pharmacy, metallurgy, machinery, food and other industries.
