High-Purity Stainless Steel Tubing for Semiconductor Gas Delivery Systems

Date:2025-03-11View:40Tags:steel tube factory,spiral welded pipe,api drill pipe

Semiconductor fabrication facilities require ultra-high-purity (UHP) stainless steel tubing to transport process gases with minimal contamination. Key considerations include:

  • Electropolished Surface Finish: Internal surface roughness must be controlled to Ra ≤ 0.25 μm to prevent particle adhesion and maintain gas purity.
  • Low-Sulfur 316L Stainless Steel: Sulfur content below 0.005% is necessary to improve weldability and prevent contamination.
  • Orbital Welding: The semiconductor industry relies on automatic orbital GTAW (gas tungsten arc welding) with 99.999% pure argon shielding to ensure defect-free welds.
