Cu-Ni alloy, a new grade of stainless steel, is specifically designed for refrigerant piping, aiming to replace copper pipes in air-conditioning equipment. It’s with Exceptional Corrosion & Pressure Resistance, Excellent Ductility & Flexibility, Low Strain Hardening and Excellent Economy and can replace copper tubes as Cu-Ni Air-conditioning Refrigerant Pipe Linesets.

Guangdong Gofar New Material is supplying DN2020mm and DN2320mm stainless steel welded tubes for nuclear station projects in Xinjiang, China.  

What are the most common grades of stainless steels?

Testing is always an efficient way to help identify any defects in the steel tubes and determine the mechanical and chemical properties of it. This will ensure that the steel pipes meet the requirements for particular applications.

Manufacturing standard defines the chemical and mechanical properties of the stainless steel tubes/pipes, ensures that the products are made to a consistent quality and specific dimensions so that they will fit together correctly when assembled.

Rolling is a metal forming process that employs the use of a series of rollers to alter the shape, improve the uniformity, and/or enhance the mechanical properties of materials. Rolled steel can be categorized into two types—hot rolled steel and cold rolled steel—which demonstrate distinct characteristics that make them suitable for different applications. When choosing a rolled steel material for a project, it is important to be aware of the differences between the two types and how they affect their performance.

Deburring and chamfering both are the process aiming to remove the raised edges and unwanted pieces or chips of stainless steel pipes.

Stainless steel is a type of alloy that contains a high percentage of chromium, which makes it resistant to corrosion and staining. However, to maintain these properties, it is often necessary to do heat treatment to the steel to improve its mechanical properties. By heat treatment, you can improve their corrosion resistance and extend their life.
