Tungsten Carbide Washer
What is Washer?
Washer, is widely used in machinery, equipment, piping and where with fluid. Which is a kind of material with high sealing application. Washer with two material for metal and nonmetallic, after cutting, stamping or cutting process made, mechanical seals and mechanical seal between the pipe connection between the machinery and equipment used in connection. Washer material can be divided into metal washer and non-metallic washer.
Properties
Tungsten carbide washer with high hardness, wear resistance, strength and toughness, and also with excellent properties of heat-resistant, corrosion-resistant and so on. Especially its high hardness and wear resistance, even at a temperature of 500 ℃ also remained unchanged, at 1000 ℃ still with high hardness.
Features
1. Tungsten carbide washer with high wear resistance and corrosion resistance, is widely used in petroleum and chemical industry, products include PH, TH and so on, the specification is from ?12mm to ?300mm.
2.After grinding, with minimum dimensions and tolerances, and excellent sealing performance.
3.Adding corrosion-resistant rare elements in processing, with more durable sealing performance.
4.Use high strength and hardness tungsten carbide material, with no distortion and more compression.
