Company Introduction:
Zonco has been specialized in customizing various kinds of non-standard
tungsten carbide wear resistant components for more than 10 years.Our products and technologies have been widely applied in the fields of oil & gas (such as downhole tools(dill bits, chrismas tree, RSS, PDM), wellhead
equipment, subsurface valves, MWD/LWD Tools) and chemical engineering, subsea, valve, pump, mechanical equipment. Mainly used in harsh operating conditions include severe
abrasion, erosion, corrosion, high temperature, high pressure and
strong impact. we are able to manufacturing all kinds of wear resistance valve
parts based on customer's drawing and material requirement, support
hardfacing process based on customer's technique requirement. since most of our products are customized and not suitable to show
for other customer, welcome to contact us for OEM service.
