Stainless Steel High Pressure Tubing 1/4in OD, ASME SA210-A1, Heat Exchanger Tubes
Stainless Steel High-Pressure Tubing (1/4" OD) by Jiangsu China Steel Union Industrial Co., Ltd is designed for precision heat transfer applications in power plants, HVAC systems, and industrial heat exchangers. Compliant with ASME SA210-A1, these tubes deliver exceptional strength and thermal conductivity under pressures up to 3,000 psi and temperatures ranging from **-50°C to 600°C**. Crafted from high-purity stainless steel, the 1/4" outer diameter (6.35mm) and ultra-thin walls ensure efficient heat exchange in compact systems while resisting oxidation, scaling, and corrosion from steam, condensate, and aggressive coolants. Seamless manufacturing and rigorous testing guarantee leak-proof performance in critical thermal management applications.
