Product Description

Product Description

A cemented carbide valve core is used in high-pressure choke valves primarily due to its exceptional wear resistance, making it ideal for applications with high flow rates and abrasive fluids, commonly found in oil and gas wellheads, where extreme pressure drops and erosive conditions can rapidly damage standard valve materials; essentially, the hard carbide composition effectively withstands the harsh wear and tear caused by high-velocity fluid flow with particles like sand or debris.
 

Grade:YG6, YG8, YG15, YG20, etc.

Size: customized
Product Features:

• Erosion resistance:

  Cemented carbide offers superior resistance to erosion, a major concern in high-pressure choke valves where fluid flow at high velocity can wear down the valve components quickly. 

   
• High hardness:

  The material's high hardness ensures long-lasting performance even under extreme pressure and abrasive conditions. 

   
• Suitable for severe service:

  Choke valves are considered "severe service" applications due to the harsh operating conditions, and cemented carbide is a preferred material for such situations. 

   
• Customizable composition:

  Different grades of cemented carbide can be selected based on specific application requirements, allowing for optimization of wear resistance and other properties.

Application

• Oil and gas wellhead control: Controlling the flow of crude oil and natural gas from a wellhead, where high pressure and potential for abrasive particles exist. 
   
• Subsea production: Choke valves used underwater in offshore oil and gas operations. 
   
   
• Gas injection wells: Regulating the flow of gas injected back into a reservoir.

FAQ:

Q1 : Are you Factory or trading company ?
We are Factory with 20 years of production experience.

Q2: What is the producing process?
Production process including powder process → formula according to the use requirements → wet grinding → mixing → smash → dry → sieving → add binder → dry again → get the mixture after sieving → pelletize → pressing → forming → sinter-hip → forming (blank) → blanks checking → passivating treatment → cylindrical grinding (according to the customer request) → cleaning → inspection of the finished product → packaging → entering warehouse.

Q3: How to control the products quality?

All products will be tested before bulk production, and we will check the physical properties, shape and tolerance for ensuring qualified products before shipping.
