Professional Copper Crush Washer Low Coefficients Of Friction
Product description
Copper washer is a kind of metal coated washer which is non-magnetic, conductive, heat-conducting and corrosion-resistant. Therefore, it can be used in heat exchanger, pressure vessel and other high temperature and high pressure sealing parts to effectively prevent washer scattering and medium erosionThe solid Copper washer is machined by mechanical cutting, and its excellent softness can fill the uneven part of the flange surface. Wide range of application temperature, low leakage. We provide various specifications and types of solid coppergasket. At the same time, we choose different copper products to manufacture washer according to customer requirements, such as: copper, brass, etc.
Performance of Copper washer:
Service temperature: about 500 ℃, melting point: 1083 ℃, hardness: before quenching ≥ 60hb, after quenching ≤ 45hb
Gasket tolerance:
1. Outer diameter: + 0.0 ~ -0.1;
2. Inner diameter: + / - 0.1;
3. Thickness: + / - 0.1
product advantage
1. Solid copper washer has outstanding effect in vacuum flange;
2. The softness of the copper washer can fill the uneven surface of the flange;
3. The copper washer is easy to process and can be produced in any specification and type.
4.It is suitable for sealing the flange of pressure vessel with large diameter (such as heat exchanger, reactor, etc.) with good sealing effect

Product application
Generally, the copper gasket adopts the local sealing with thread. Its sealing principle is that the two joint surfaces extrude the copper gasket, so that the two surfaces of the copper gasket fit closely with the two joint surfaces without any gap, so as to obtain the sealing effect. In order to achieve the sealing effect, annealing treatment is generally carried out before use, the purpose of which is to make the copper sealing ring soft, so as to achieve better sealing effect, and effectively prevent the corrosion of the gasket and the medium. Therefore, it is generally used at the joint with installation groove.
The application and defense of copper gasket are very extensive, and the preload required by the gasket is also different. For example, the gasket used for the thin flange of low-pressure water pump needs a lower preload, which is suitable for various economic fields such as national defense, electric power, machinery, petroleum, chemical industry, metallurgy, paper making, shipping, transportation, etc., with complete specifications and stable quality, and the products are sold all over the world.
