📍 Products Description
Stainless Seamless Steel Pipe Tube
BA Polished Steel Tube
Key Specifications:
• Delivery condition: AP, BA, CFA, CFP
• OD Range: 1mm - 250mm | WT Range: 0.05mm - 50mm
• Tolerance: OD +/-0.05mm, ID +/-0.05mm
• Advantage: Sophisticated bright annealing technology ensures excellent mechanical performance. The tube can be flared, flattened, and bent freely.
🚀 Applications
Hydraulic/Automobile Pipe Good roughness enables tube to withstand high pressure; excellent mechanical performance guarantees free bending, flaring, and end processing.
Laboratory Gas BA+ process reaches Ra ≤0.375. Regular sizes: 6.35*1, 9.35*1, 12.7*1.24, 25.4*1.65 etc.
Food/Beverage & Pharma High precision with lower tolerance. ID roughness Ra ≤0.6, OD tolerance ≤±0.05mm.
Semiconductor Ra ≤0.375 with special cleanness for inner diameter requirements.
