Lightweight Stainless Steel Thin Wall Pipe 0.35mm ASTM A554 Stainless Steel Tubing
Lightweight SS High Pressure Pipe 0.35mm Thin-Wall, ASTM A554, HVAC Ducting
Lightweight Stainless Steel High-Pressure Pipes (0.35mm Thin-Wall) by Jiangsu China Steel Union Industrial Co., Ltd revolutionize HVAC (Heating, Ventilation, and Air Conditioning) systems with their ultra-thin, corrosion-resistant design. Compliant with ASTM A554, these pipes combine Grade 304 or 316L stainless steel to deliver high-pressure performance (up to 25 bar) while reducing weight by **50%** compared to traditional ducting. The 0.35mm wall thickness and seamless/welded construction ensure optimal airflow efficiency, making them ideal for commercial buildings, hospitals, and cleanrooms. Electropolished surfaces (Ra ≤0.4µm) minimize friction loss and microbial growth, adhering to ASHRAE hygiene standards.
