Flange Washers also be known as "Flange Bolting Washers", "Spring Washers", be used for the connection between flange and bolt. Its application equipment includes: Reactor, stirrer and heat exchanger flange bolts; Pumps, Fans, Centrifuge Flanges and Anchor Bolts; Power bus and copper alloy bolts;Pipe flange and valve flange bolt. Flange Washers are widely used in industries such as Petrochemical, Power, Metallurgy, Paper, Pharmaceuticals, Food Processing, etc. Bolt flange joints are widely used in pressure vessel and pipe connections, and Leakage is the main failure mode of bolt flange connections. The main causes of leakage includes: differential thermal expansion/contraction, vibration, bolt creep and vibration. By installing flange washers in bolt flange joints, the elastic potential energy stored in the China Flange Bolting Washers can be converted into mechanical energy, to compensate the deformation of gasket and bolt, to ensure the bolt preload meets the sealing requirements, prevent leakage. How do we choose the right flange washers? Firstly, choose size of wholesale flange washers according to the bolt model & required load value. Then select the suitable raw material further according to the application environment. Material such as H13, 17-7PH, Inconel 718 (see the material document for details) are available in case of high temperature, cryogenic (low temperature) and anti-corrosion environment.

A co2 gas type fire extinguisher is a type of fire extinguisher that uses carbon dioxide gas as the extinguishing agent to suppress fires. CO2 fire extinguishers are effective for Class B (flammable liquids) and Class C (electrical) fires. They work by displacing oxygen and cooling the fire, thus removing the heat source and extinguishing the flames. CO2 fire extinguishers are commonly used in environments where water-based extinguishers might cause damage or where a clean agent is required.
