Application of tungsten carbide ball
♦ Material: cobalt-base alloy, nickel -base alloy and stellite alloy, Titanium carbide and other corrosion resistant
material.
♦ Application fields: Subsurface pump/Oilfield Tubing pump/Insert pump, sealing, it is widely used in petroleum industry and other anti-corrosion machine parts.
♦ Properties: Seat-ball valves for oilfield Insert Pumps have good resistance against corrosion and oxidation;
Tungsten carbide valve ball and seat are widely used in petroleum drill and exploitation equipment. It's used to the stationary
and roving unidirectional valve in various tube-type oil suction pump due to their high hardness, wear and corrosion resistance as well as good anti-compression and thermal shock characters with a high pump effect.
