Spiral Twisted Tubes

Product Overview
Spiral Twisted Tubes are a key product category of our heat transfer tube production line. Manufactured from TP304, TP316L, and S32205 stainless steel materials, these Stainless Steel High Performance Tubes are produced according to ASTM A269, ASTM A312, and ASTM A249 standards.
Our Spiral Twisted Tubes are formed through tube flattening and spiral twisting processes. The internal spiral flow channel enhances fluid turbulence, while the external flat spiral structure increases heat transfer contact area. These tubes provide excellent heat transfer performance with good vibration resistance and corrosion resistance for various heat exchange requirements.
