Stainless Steel Inner and Outer Grooved Tubes

Product Overview
Stainless Steel Inner and Outer Grooved Tubes are high-performance Heat Exchanger Tubes designed for efficient heat transfer applications. Manufactured from TP304/304L and TP316/316L stainless steel materials, these tubes feature spiral groove structures formed on both the inner and outer surfaces.
The internal and external grooved designs increase heat transfer surface area and enhance fluid turbulence, improving thermal exchange efficiency compared with conventional smooth tubes. With high dimensional accuracy and uniform groove forming, these Stainless Steel Heat Exchanger Tubes are widely used in condensers, evaporators, refrigeration systems, and industrial heat exchange equipment.
Customized solutions are available for tube diameter, wall thickness, tube length, groove structures, and surface treatment according to different equipment requirements.
