Metal Spinning Solutions for Chemical Processing Equipment

Metal spinning is widely used in the chemical and petrochemical industries to manufacture corrosion-resistant, pressure-resistant, and hygienic components. Compared to welded fabrication, spun components offer seamless structures, uniform wall thickness, and improved structural integrity, making them ideal for containers, reactor parts, and storage vessels. At King Metal Spinning Co., Ltd, we specialize in stainless steel and nickel alloy metal spinning, ensuring long-term performance in aggressive chemical environments.

What Materials Are Used in Chemical Metal Spinning?

Material selection is critical for chemical applications.

Common Materials:

SUS304 / SUS316L → corrosion resistance & hygiene
Nickel-based alloys → high-temperature & chemical resistance
Aluminum (5052) → lightweight containers (food-grade)

👉 Engineering Insight:
SUS316L is preferred for acidic and chloride environments, while nickel alloys are used for extreme corrosion and high-temperature conditions.

How to Ensure Corrosion Resistance in Spun Components

Key Challenges:

Chemical corrosion
Surface contamination
Material degradation

Our Solutions:

High-grade raw material control
Seamless forming (reduced welds)
Electropolishing for stainless steel
Surface passivation

👉 Result:
Long-term durability and resistance to chemical attack.

What Tolerances Are Required for Chemical Equipment?

Chemical equipment requires stable dimensional accuracy to ensure sealing and assembly.

We achieve:

Diameter tolerance: ±0.5 mm (large vessels)
Height tolerance: ±1 mm
Wall thickness uniformity control
Critical interfaces: full inspection

👉 Key Advantage:
Spinning ensures consistent wall thickness, reducing failure risks under pressure.

How to Achieve Hygienic and Mirror Surface Finishes

For food-grade and chemical applications:

Electropolishing (Ra ≤ 0.4 μm)
Mirror finish internal surfaces
Burr-free edges and no dead corners

👉 Critical Benefit:
Prevents material residue buildup and contamination.

Chemical Metal Spinning Capabilities

Large-diameter spinning (Ø500 mm+)
Deep cavity forming (e.g., 180L containers)
Multi-pass flow forming
Secondary processing:
- CNC machining
- Polishing & electropolishing
- Welding (if required)
