Hastelloy C-276 16-inch flange

CGN’s key flange fittings are ready for shipment.(HY-marketing department)

Notice of shipment goods:

Recently, a batch of nuclear power pipe flange fittings manufactured by Shanghai HY Industry Co., Ltd. completed the final testing procedure. All the indicators are in full compliance with the design parameters. They are ready for packing and transported to CGNPC. The nuclear components will be used. CGN’s nuclear power cooperation project in the UK, the installation of the test machine to ensure the design is correct, will be mass-produced, especially the Hastelloy C-276 16-inch and 24-inch large flange, the quality represents the cutting-edge level of China’s superalloy field, the future Mass production in the future will bring lucrative profits to Shanghai HY Industry Co., Ltd. flange fittings:Hastelloy C-276 16-inch flange

Hastelloy C276





Characteristic as below:

  1. Excellent corrosion resistance to most of corrosion media in oxidation and reduction

  2. Excellent resist pitting, crevice corrosion and stress corrosion cracking

Hastelloy C276 Metallurgical structure:

Hastelloy C276  is face-centered cubic lattice structure.

Hastelloy C276 Corrosion resistance:

C276 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make it corrosion resistance better.C276 is one of a few material that can resist the corrosion of most chlorine, hypochlorite and chlorine dioxide, this alloy have prominent corrosion resistance to high concentration chlorate( iron chloride and copper chloride).

Hastelloy C276 Application field:

C276 is widely used in the chemical field and petrifaction field, such as the element of chloride organic and catalyze system. This material especially suit for high temperature environment, impure inorganic acid and organic acid (such as formic acid and acetic acid), sea-water corrosion environment.

Other application field:

  1. The digester and bleacher in the use of paper pulp and paper making

  2. Absorption tower, re-heater and fan in the FGD

  3. The equipment and parts in the use of acidic gas

  4. Acetic acid and anhydride reaction generator

  5. Sulfur acid cooling

  6. MDI

  7. Manufacture and processing of impure phosphoric acid.
