We are committed to providing high-quality products for the oil and gas exploitation with its advanced equipment, strict and effective quality control system, excellent processing technology and the most competitive price. Our products are mainly exported to the United States, England, Russia, Kazakhstan, Oman, South America and other overseas markets, as well as part of the domestic market. Our production of valve balls and valve seats of various materials such as tungsten carbide, titanium carbide, nickel carbide, cobalt alloy (Stellite), stainless steel, Zirconium Oxide(ZrO2), Silicon Nitride(Si3N4), etc. And has an annual production capacity of more than 200,000 sets. Zhuzhou Harmony New Material Co., Ltd. is good at providing different solutions for customers based on different well environment and different customer's individual needs.
We are able to manufacturing all kinds of tungsten carbide components for different applicants, customized manufacturing carbide sealing rings/balls and seats/valve trims/bushing/sleeves wear parts with high quality.
1. Our special developed materials for Tungsten Carbide Bearing components have the characters of high wear resistance, corrosion resistance and erosion resistance.
2. Made from our special designed tungsten carbide materials, our carbide components shows high hardness and transverse rupture strength, and has superior performance on abrasion, erosion and corrosion resistance, which enable it to be widely used in petrochemical industries and other industries.
3. There have three major series of tungsten carbide grades are WC+Co, WC+Ni and WC/TiC+composite binders, based on different applications. WC+Co series carbide components have high transverse rupture strength, and WC+Ni grades have good rcorrosion resistance, while the composite binder grades are mainly for erosion resistance purpose.
We also provide OEM service and welcome your enquiry.
