Tailor-made for customers all kinds of pumps with my company, kettle, bearing no pressure sintering silicon carbide mechanical seal, and all kinds of resistance corrosion pump parts and the accessories. Our company pressureless sintered silicon carbide products a reaction bonded silicon carbide products, can easily adapt to the harsh working conditions, in strong corrosive, strong wear, high temperature, high pressure, high strength harsh harsh under complex conditions is more outstanding. At the same time, our company to provide customers with nozzles, armored body armor plate and other special-shaped pieces of custom-made service.
Compared with the reaction sintered silicon carbide product (SSIC), the production process of the sintered silicon carbide product (RBSIC) is complex and the production investment is high. In addition, whether it is in the resistance to corrosion and abrasion, compressive and flexural fracture resistance of or high pressure, high temperature and other properties are more excellent, this is pressureless sintering silicon carbide products will in the near future completely replace reaction bonded silicon carbide products is one of the important reasons. The main varieties of the pressureless sintering silicon carbide products with all kinds of mechanical seal with sealing ring and moving ring and static ring, corrosion resistant pump, magnetic pump, shield pump components. At the same time, the production special-shaped pieces of nozzle, wire drawing die, armor plate. According to the drawings, we will provide customers with satisfactory products and customer satisfaction. Let customer satisfaction is one of the purposes of our company has been pursued, but also one of the objectives pursued by all the staff of our company.
Features: high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, hardness, heat conduction
Main products: mechanical seals, pump parts, nozzles, bullet proof plate
Mechanical seals: high hardness, high wear resistance, good self - Lubrication and high heat conductivity, so the service life of mechanical seal is greatly improved.
Pump: resistance to corrosion and wear characteristic of the pressureless sintering silicon carbide become magnetic pump sliding bearing, resistant corrosion pump sleeve, shielding pump assembly, etc. various kinds of pump of choice
Nozzle: wear resistant, high temperature resistance, high hardness characteristics of the normal pressure sintering silicon carbide nozzle to become a perfect alternative to carbide nozzle
Armor: light weight, high hardness, good ballistic performance, pressureless sintering of SiC for your life and property security escort
