Product Description
Detailed Product Description:
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.
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, multistage choke manifold)
3. Customized tunsgten carbide choke valve stem and seat according to customers' drawings
Product features:
1. Heat resistant; very good wear resistant
2. HIP sintering, High hardness.
3. Good impact toughness, chemical stability.
4. Excellent performance and good wear/corrosion resistance
5. High machining accuracy/precision.
