Tungsten Carbide Seal Rings for Mining and Oilfield Equipment
Why Tungsten Carbide Is Used as a Severe-Service Seal-Face Material
Tungsten carbide is a cemented carbide consisting of hard WC grains held together by a metallic binder.
Its usefulness in mining and oilfield seal applications comes primarily from the combination of:
● high hardness
● resistance to abrasive wear
● high stiffness
● mechanical strength
● ability to maintain a precision working surface when the grade and seal design are appropriate
Where Tungsten Carbide Seal Rings Are Used
Mining and Slurry Pump Seals
Mining pumps may handle ore slurries, tailings, mineral fines and process water containing abrasive solids.
When solids reach the sealing interface, softer faces can experience rapid scoring or wear. Tungsten carbide may therefore be considered as a hard seal-face material where abrasive wear is a dominant concern.
Oilfield Process and Production Pumps
Tungsten carbide seal rings may be used in mechanical seals for oilfield and petroleum-service pumps handling fluids such as produced water, hydrocarbons, injection water or other process media.
For these applications, material selection should consider:
● solids or sand content
● fluid chemistry
● chloride level where relevant
● lubrication condition
● mating-face material
● temperature
● shaft speed
● seal arrangement
● required drawing specification
Mud and Solids-Handling Equipment
Mechanical seals in equipment handling drilling mud, mineral slurry or contaminated fluids may encounter abrasive solids combined with changing pressure, vibration and lubrication conditions.
Tungsten carbide can be useful where maintaining a wear-resistant sealing surface is important, but the seal-face geometry and system design still determine whether solids can enter and damage the interface.
Custom Tungsten Carbide Seal Rings to Drawing
Langsun Carbide manufactures custom tungsten carbide seal rings from customer drawings and application requirements. Its current product information confirms WC-Co/WC-Ni material options, custom dimensions and geometry, dimensional tolerances, grooves/steps and surface-finishing requirements.
Custom requirements can include:
● non-standard OD and ID
● ring thickness
● seal-face geometry
● grooves
● steps
● notches
● chamfers and radii
● WC-Co or WC-Ni material requirements
● drawing-defined tolerances
● surface grinding and finishing requirements
For mining and oilfield replacement components, send:
Drawing + application + fluid + existing grade + failure information whenever available.
