Model NO.: OEM various size Application: Pumps Performance: Wear Standard: Standard, Nonstandard Gurantee: 3year Precision: High Guarantee: 3years Trademark: hongzuan Specification: SGS HS Code: 848420009 Material: Metal Rubber Type: Oil Seal Shape: -Ring Size: D4-400mm Sample: complimentary MOQ: No distribution: Fast Transport Package: Paper, wood, Plastic Origin: Zhuzhou Tungsten Carbide Dynamic And Static Rings For Trunion Air Seal we could casting the components with weight From 0.1kg to 100kg in material of metal alloy, stainless, aluminum, metal, Copper , bronze an such like. 4.Material consist of:tungsten carbide cobalt(WC-Co), tungsten carbide nickel(WC-Ni), silicon carbide, ssic, Rbsic, etc. Six Sigma & Lean manufacturing capable maker of standard & custom silicon carbide & tungsten carbide hard face seals. The alloys associated with coatings 26l also have about 5 times the Wear resistance associated with the heretofore utilized molybdenum and chromium hard-facing product, and for that reason much thinner coatings can be utilized.
Silicon Carbide Seal Rings have the property of excellent resistant-corrosion, high mechanical power, high thermal conductivity, good self-lubrication used as seal faces, bearings and pipes in spacecraft, equipment, metallurgy, publishing and dyeing, foodstuff, pharmaceutical, auto industry etc. Whenever sic faces are along with graphite faces the friction is the littlest and they can be converted to technical seals which are in a position to work with highest performing demands.
Making use of tungsten carbide powder as natural material, incorporating appropriate level of cobalt powder or nickel powder as a binder, pressing into a band shape by a specific mildew, and sintering in vacuum pressure furnace or a hydrogen reduction furnace. Another object of this invention would be to offer rings with a temperature and wear-resisting hard-facing refractory steel carbide alloys which Will maybe not unduly Wear an engine cylinder and which have a larger power under wide temperature ranges than heretofore known hard facings on piston rings.
25, 1966 Even though the ame spray used molybdenum difficult facing material disclosed in these patents afforded the heretofore best known performances for piston rings in high-compression, high-temperature operating interior combustion machines cemented carbide, motor builders consistently increase compression ratios, running heat ranges, and speed requirements and consistently demand even greater perfection in piston band performance.
We machine seal rings the subsea coal and oil industry, in which item life is crucial. And whether tungsten carbide wear resistance seal bands is free samples, or compensated examples. An. alloy with a tungsten carbide content of 22 per cent was found to quickly scuff also to increase the bore use beyond the quantities encountered with the alloys of the invention.
Tungsten carbide is the better product to resist heat and break in every hard face materials. Tungsten Carbide Shapes – like ceramics tungsten carbide are often formed into monolithic forms for applications particularly valve seats, seal rings, nozzles, bushings along with other technical components. The refractory metal carbide content may vary dramatically so long as the carbides have been in solution in alloy and are reasonably clear of sharp edges and corners which cause pull-out during operation.
