Stainless Steel Degreasing Coil for Oxygen Pipelines

Huaxiao-Alloy’s degreased stainless steel coils are engineered for high-purity oxygen delivery systems in strict compliance with GB/T 40317-2021. These coils undergo specialized degreasing and passivation processes to eliminate hydrocarbons, particulate contaminants, and metallic ions, ensuring absolute safety in medical and industrial oxygen pipelines.

1. CRITICAL REQUIREMENTS FOR OXYGEN PIPELINE SAFETY

Explosion Prevention
- High-purity oxygen (≥99.99%) at pressures exceeding 3MPa can trigger spontaneous combustion upon contact with hydrocarbon residues (e.g., oils, greases).
- Degreasing removes all combustible contaminants, preventing ignition risks during high-velocity oxygen flow.
Surface Cleanliness
- Metallic ions and organic particles are eliminated to avoid oxidation-induced sparks under high-pressure conditions.
- Electropolished internal surfaces (Ra ≤ 0.8μm) minimize adhesion points for pollutants.

2. COMPLIANCE & VALIDATION

Standards Adherence: Fully compliant with GB/T 40317-2021, ISO 15001 (Oxygen Pipeline Systems), and ISO 13485 (Medical Devices).
Quality Verification: Each coil undergoes third-party testing for non-volatile residue (NVR), particle counting, and FTIR spectroscopy to validate hydrocarbon-free status.

3. TYPICAL APPLICATIONS

Medical oxygen pipelines in hospitals and healthcare facilities
Industrial oxygen systems for metal cutting, welding, and chemical processing
High-purity gas distribution in semiconductor manufacturing
