Copper gasket supply

Copper gasket belongs to a type of metal coated gasket, which has good performance, outstanding wear resistance and compression resistance.

Copper gaskets have excellent conductivity, thermal conductivity, ductility, and corrosion resistance. Mainly used for the production of electrical equipment such as generators, busbars, cables, switchgear, transformers, as well as thermal conductivity equipment such as flat plate collectors for heat exchangers, pipelines, and solar heating devices.

The copper gasket is made of purple copper sheet with good weldability, which can be processed into various semi-finished and finished products through cold and hot plastic processing, ensuring a tight fit between the metal surface and the flange sealing surface. The room temperature tensile strength of annealed sheet is 22-25 kgf/mm, elongation is 45-50%, and Brinell hardness (HB) is 35-45. It can meet various requirements of customers such as quenching, washing, etc. The maximum applicable temperature is 800 degrees Celsius. Suitable for pressures ranging from 2.0Mpa to 42MPa.

Every household in the copper gasket factory uses various types of boards, and the highest temperature used is 600 degrees Celsius. Practical pressure ranges from 6.3 to 250 bar. Mainly used for valve flange connections, with good sealing performance. The product specifications of the copper pad manufacturer range from DN15 to DN900.

Copper gaskets generally require annealing treatment during use. Annealing is a metal heat treatment process that involves slowly heating the metal at a constant temperature for a sufficient period of time, maintaining a suitable cooling rate, and reducing hardness to improve machinability; Eliminating residual stress to stabilize dimensions and reduce deformation and crack tendency; Refine grain size, adjust microstructure, and eliminate structural defects. After annealing treatment, the gasket will become soft and can have a tightening and sealing effect. The annealing treatment of copper gaskets can refine grain size, adjust structure, and eliminate structural defects, which is a treatment method that has many effects on gaskets.
