Our tailored to customers all kinds of pumps, kettle, bearing sintered silicon carbide mechanical seal, corrosion resistant pumps and various accessories used through the referral site. My company's products than non-sintered silicon carbide reaction bonded silicon carbide products can easily adapt to harsher working conditions, in strong corrosion, wear strong, high temperature and pressure, high strength demanding harsh working conditions performance is more complex as well. Meanwhile, the company provide customers with nozzles, bulletproof armor plates and other shaped pieces of customized services.
Pressure sintered silicon carbide products (SSIC) compared to reaction-bonded silicon carbide products (RBSIC) complex production process, high production inputs. In addition, both in corrosion resistance, abrasion resistance, flexural compressive fracture resistance or high pressure, high temperature properties are even more outstanding performance, which is sintered silicon carbide products will be in the near future completely replace a reaction-bonded silicon carbide products for important reasons. Sintered silicon carbide products, the main varieties my company produces a variety of mechanical seals seal ring, ring, quiet ring, corrosion resistant pumps, magnetic pumps, pump shield assembly, while the production of the nozzle, drawing dies, bulletproof armor plate and other shaped pieces. We will produce according to drawings clients to sell customer satisfaction. Customer satisfaction is one of the purposes of our company has been pursuing, but also one of the goals of our company staff pursued.
Features: high temperature, wear, corrosion, oxidation resistance, hardness, good heat conduction
The main products: mechanical seals, pump parts, nozzles, bullet-proof plate
Mechanical seals: high hardness, high wear resistance, good self-lubricating properties and high thermal conductivity of the mechanical seal life greatly improved
Pump parts: corrosion and wear-resistant features make atmospheric SiC become magnetic pump sliding bearings, bushings choice for corrosion resistant pumps, pump shield pump assembly and other parts
Nozzle: wear-resistant, high temperature, high hardness features make atmospheric SiC carbide nozzles nozzles become perfect substitutes
Bulletproof plate: light weight, high hardness, good ballistic performance, atmospheric SiC for your life and property security escort
