Rolling Bending Tubing Solar Hot Water Heat Exchanger

Discover how precision rolling-bending technology forms high-quality tubing for solar hot water heat exchangers. This video demonstrates smooth coil forming, consistent radii, and accurate tube shaping—ideal for solar thermal systems, HVAC heat exchangers, and energy-efficient heating applications.


This video demonstrates the complete rolling bending process used to form tubing for solar hot water heat exchangers. Using precision coil-forming equipment, the tube is gradually shaped into smooth, uniform coils with consistent radii and excellent dimensional accuracy. This method ensures stable flow characteristics, minimal deformation, and improved long-term reliability—critical features for all solar thermal heating systems.

Rolling bending is widely used for manufacturing solar hot water coils, heat exchanger tubing, HVAC coils, spiral tube heaters, and compact thermal modules. Compared with manual bending or multi-segment forming, rolling bending provides superior roundness, tighter bending control, and higher production repeatability. This results in better thermal performance, reduced pressure loss, and longer service life.

Whether used in residential solar water heaters, commercial solar boilers, industrial heat-exchange units, or renewable-energy heating systems, precision tube bending is essential for achieving efficient heat transfer.
