OEM/ODM Wear-resistance Corrosion Resistance Tungsten Carbide Valv
Seat
Tungsten carbide seats are used for various Oil Field Equipment and
Oilfield Valves such as Conventional Gas Lift Valves, Wireline
Retrivable (WLR) Injection Pressure Operated (IPO) Gas Lift Valves
etc.
API Standard Cobalt Alloy Valve Seats and Valve Balls
1. Valve balls and valve seats are widely used in oil fields.
2. Valve Ball and Seat performance directly affects the use effect
and service life of the sucker rod pumps.
3. Each ball-and-seat combination is vacuum tested to ensure a
perfect seal is obtained in all positions of contact.
Main Features
1. Material: Stainless steel; Cobalt Alloy, cast; Cobalt
Alloy,Tungsten Carbide, Titanium Carbide .
2. Standard: API 11AX .
3. High resistance against corrosion and oxidation;
Balls made of tungsten carbide is also called hard alloy balls. It
is used for applications requiring extreme hardness and resistance
towear and abrasive, hard shocks and impacts.
The appliations includespecial valves, flow meters, recirculating
balls bearing screws, liner bearing and balls for ball point pens.
They are also used often for mining, as pivols and points of
comparations. They are als used for measurements anor colibrations
of holes and measurement checking devices.
