FAQS

Fused Ceramsite Sand (Baozhu Sand)

Posted on 2025-09-29

+

Applicable Castings:

-Pump housings, valve bodies, pipeline fittings (steel and ductile iron)

-Wellhead components such as flanges and casing heads

Processes:

Resin-bonded sand, coated sand, V-process

Why It Works:

-High refractoriness (1850℃) → withstands steel and iron melts

-Low thermal expansion → prevents cracks in thick-walled pump/valve castings

-High strength & reusability → cost-efficient for large batch production

Tushun AluSphere (Special Sand for Aluminum Casting)

Posted on 2025-09-29

+

Applicable Castings:

-Aluminum housings for control devices and instrumentation

-Lightweight pump or compressor parts in offshore oil/gas equipment

 

Processes: Low-pressure casting, gravity casting with sand cores

 

Why It Works:

-Optimized for aluminum alloys → high surface quality, fewer gas defects

-Helps reduce weight in non-structural components for oilfield tools

High-Strength Fused Sand (Specialty Sand)

Posted on 2025-09-29

+

Applicable Castings:

-High-pressure valve bodies, choke valves, gate valves

-Pump impellers, turbine housings, and wear-resistant steel parts

-Nickel/Co-based alloy parts for drilling and subsea equipment

 

Processes: Precision casting, resin-bonded sand

 

Why It Works:

-refractoriness ≥1800℃ → ideal for high-temperature, corrosive environments

-Mohs hardness 8–9 → resists erosion by slurry, sand, and corrosive fluids

-Stable chemistry → suitable for harsh oil & gas well service conditions
