Tungsten Carbide Parts for Petroleum and Petrochemical

Pumps and valves in petroleum and petrochemical service handle fluids with sand, catalyst fines, and corrosive agents. Steel and coated components wear quickly under these conditions. This page covers the tungsten carbide bushings and sleeves made here for that duty and how they are specified.

What Goes Wrong Today

  • Valve rod sleeves wear out quickly in sand-laden or corrosive fluids, leading to increased leakage and mechanical seal failure
  • Bearings and shaft seats develop clearance due to wear, causing vibration and premature failure
  • Parts from different suppliers do not match, making rebuilds inconsistent and unreliable
  • High machining allowances on carbide blanks increase the cost of finished parts
  • Lack of material consistency leads to variable wear life across batches

What Buyers In This Sector Need

  • Bushings and sleeves that resist abrasive and corrosive wear over a full maintenance cycle
  • Parts made to an existing pump or valve drawing without redesign
  • Matched pairs of bushings and shafts with consistent fit and low clearance
  • A sample that can be tested in service before committing to a bulk order
  • Repeatable dimensions and material properties across reorders for consistent rebuilds

Typical Applications

  • Valve rod sleeves in submersible oil pumps handling crude with entrained sand
  • Shaft sleeves in slurry pumps used in mineral processing and tailings lines
  • Bushing components in centrifugal pumps exposed to sea water and corrosive chemicals
  • Bearings and shaft seats in wellhead and injection valves under high pressure and solids
  • Custom-shaped bushings made from customer drawings for special pump or valve designs

Delivery and Lead Time

  • Stock items ship 3-5 days after payment is received
  • Customised items carry a stated delivery time in the quotation
  • Existing moulds across many models reduce production time for repeat shapes
  • Physical properties shape and tolerance checked before shipping
Process

How An Enquiry Becomes A Delivered Part

Step 1

Send drawing plus fluid type temperature and pressure cycle

Step 2

Grade selected based on the service environment rather than a default material

Step 3

Mould selected from existing tooling or a new mould made if needed

Step 4

Pressing using imported press, sintering in over-pressure furnace

Step 5

Grinding to drawing with tight tolerance control

Step 6

Sample supplied for pre-testing if required

Step 7

Inspection photographs sent for confirmation before delivery

FAQ

Petroleum and Petrochemical FAQ

Which carbide grade suits sand-laden crude in valve sleeves?

Lower cobalt grades such as YG6 offer better wear resistance in abrasive environments. For applications with pressure shock, higher cobalt grades like YG15 may be preferred.

Can you supply matched bushing and shaft pairs?

Yes. Bushings and shafts are supplied together to ensure consistent fit and mating surface quality.

Do you work from our pump or valve drawings?

Yes. OEM and ODM to customer drawings is standard, including non-standard and specially shaped parts.

Can we test a sample before placing a bulk order?

Yes. Samples are available for pre-testing before bulk production is released.

How do you ensure consistency across reorders?

Repeat parts are produced from the same mould and grade. Physical properties shape and tolerance are verified against the drawing before each shipment.

What lead time should we plan for?

Stock items ship in 3-5 days after payment. Customised items carry a delivery time stated in the quotation.
