Quick Details
Choke Valve Stem With High Precision And Good Wear Resistance
- Specifications
- Inquiry
Customized tungsten carbide choke valve stem and seat according to drawings
1. Tungsten carbide tip in conjunction with stainless steel stem provides optimum wear resistance in erosive conditions.
2. Carbide wear parts for oil and gas industry, wellhead assembly (eg. Christmas tree, multi stage choke manifold)
3. Customized tungsten carbide choke valve stem and seat according to drawings.
Hardened alloy Steel Stems and Seats are widely used in Adjustable Needle & Positive Choke assemblies. Stainless Steel or stainless steel with Tungsten Carbide tips for Abrasive and or Sours Gas Service are available on request. Positive Choke assemblies are furnished less flow bean and may be converted to Adjustable Choke assemblies by replacing the blanking cap assembly and flow bean with the appropriate adjustable bonnet assembly and seat.
The features:
1. Good wear and corrosion resistance
2. Long lifetime
3. Good working performance
4. One stop customized service
