Tungsten carbide is an inorganic chemical compound which contains numbers of tungsten and carbon atoms. Tungsten carbide, also known as “cemented carbide”, “hard alloy” or “hardmetal”, is a kind of metallurgic material which contains tungsten carbide powder (chemical formula: WC) and other binder (cobalt, nickel. etc.).
It can be pressed and formed into customized shapes, can be grinded with precision, and can be welded with or grafted to other metals. Various types and grades of carbide can be designed as required for use in application intended, including chemical industry, oil & gas and marine as mining and cutting tools, mould and die, wear parts, etc
Tungsten carbide is widely used in industrial machinery, wear resistant tools and anti-corrosion. Tungsten carbide is the best material to resist heat and fracture in all hard face materials.
Choke valve is a device used to control the flow of fluids such as well testing, wellheads, stream injection. Carbide alloy is embedded into stem needle of valve, seat. Positive chokes provide a fixed flow condition with a large selection of available bean sizes and types.Adjustable chokes provide variable flow rates but can be locked into position if a fixed flow rate is required.Choke stem and seat are the key parts for adjustable choke valves in wellhead equipment . Assembled with tungsten carbide tips and SS410/316 body. Tungsten carbide tip in conjunction with stainless steel stem provides optimum wear resistance in erosive conditions.
Customized tungsten carbide choke valve stem and seat according to drawings. Our company have a peculiar machining procedure to connect stem and core in order to avoid fall off issue.
Guanghan ND Carbide produces a wide variety of wear-resistant and corrosion-resistant tungsten carbide
components.
