Flange de formação de superfície

Mar 17 2025

Flange formed by surfacing welding is a kind of pipeline connector which is clad with corrosion-resistant or high-strength alloy material on the surface of foundation flange by surfacing welding process to improve its wear resistance, corrosion resistance and high temperature resistance. The flange is widely used in petrochemical industry, nuclear power, marine engineering and high temperature and high pressure pipeline system.

Main Characteristics of Surfacing Flange

Strong corrosion resistance: the resistance of flange in corrosive medium can be improved by surfacing welding stainless steel, nickel-based alloy and other materials.

High strength and high temperature resistance: carbon steel or low alloy steel is usually used as matrix material, combined with high temperature and corrosion resistant surfacing layer, which is suitable for extreme working conditions.

Cost advantage: Compared with integral stainless steel or alloy flange, surfacing flange can effectively reduce the cost while maintaining excellent performance.

Good weldability: the substrate can be directly welded to the pipeline, which is suitable for various installation methods.

Production Technology of Surfacing Forming Flange

Substrate processing: select suitable carbon steel or low alloy steel substrate and process it into the initial shape of flange.

Surfacing treatment: using automatic or semi-automatic welding equipment, surfacing corrosion-resistant alloy materials on the sealing surface of flange or the surface of inner hole.

Heat treatment: remove welding residual stress, optimize metallographic structure and improve durability.

Machining: precision machining of the flange after surfacing to ensure dimensional accuracy and sealing.

Surface treatment and testing: including flaw detection, surface polishing, corrosion resistance treatment, etc., to ensure product quality.

Main Application Fields of Surfacing Flange

Petrochemical industry: pipeline system for conveying highly corrosive media, such as acid-base pipeline.

Marine engineering: pipeline connection in seawater environment to prevent salt fog corrosion.

Nuclear power and energy industry: key connecting parts in high temperature and high pressure environment.

Metallurgical and pressure vessels: used in extreme working conditions, such as high temperature furnaces and heat exchange equipment.

Through advanced surfacing technology and combining the advantages of different materials, the surfacing flange can reduce the manufacturing cost while ensuring the performance, and is suitable for various harsh industrial environments. With the development of material science and welding technology, its application scope will be further expanded and it will become one of the first choices for high-performance flanges.
