TC Top Cone Ø454.82×Ø390×18 mm (Tungsten Carbide Choke Valve Trim)

Product Overview

This TC top cone is widely used in wellhead choke valves and high-pressure flow control valves. Tungsten carbide is the preferred material for choke trim because it can withstand severe wear caused by sand, particles, and high-speed fluid flow.

We manufacture TC cones based on customer drawings and support stable repeated supply for long-term projects.

Specifications

Key Features

• • High hardness and outstanding abrasion resistance

    Typical Applications

    This product is mainly used in:

    • Oil & gas wellhead choke valves
    • Christmas tree flow control systems
    • High-pressure oilfield valves and manifolds
    • Refinery and petrochemical flow control valves
    • API choke trim replacement parts
      

    Available Grades Recommendation

    • YG6 / YG8: high hardness, excellent wear resistance
    • YG11 / YG15: higher toughness, suitable for impact and heavy load
    • WC-Ni (Nickel binder): better corrosion resistance for sour gas / chemical medium

    Manufacturing Capability

    We provide:

    • Precision grinding for OD/ID
    • Lapping for sealing surface
    • Chamfer, groove, step design
    • Inspection report (dimension, hardness, density)
    • Export packing with anti-rust protection
     

Why Choose Tungsten Carbide for Choke Valve Trim?

Choke valves work under extreme conditions. Tungsten carbide top cones significantly extend service life compared with stainless steel or alloy steel parts, reducing shutdown time and maintenance cost.

FAQ 

Q1: What is a TC top cone used for?

A TC top cone is used as a wear-resistant trim component in oilfield choke valves and high-pressure flow control valves.

Q2: Can you produce TC cones according to our drawing?

Yes. We support OEM production based on drawings or samples, including strict tolerance requirements.

Q3: Do you provide finished grinding or only blanks?

We can supply both sintered blanks and fully ground finished parts.

Q4: What carbide grade is best for oil & gas choke valves?

YG8/YG11 are common options. For corrosive media, WC-Ni grades are recommended.
