HVAC and heat-exchanger tubing performs different roles across chilled-water and hot-water circuits, boiler coils, condensers, evaporators and heat-recovery equipment. TeCarve supplies seamless and welded stainless steel tubes with dimensions and surface finishes selected for the exchanger geometry, fluid circuit and fabrication method.

For OEMs and system contractors, consistent tube dimensions are important for coil forming, tube-sheet fit-up and repeatable assembly. Product selection can therefore be organized around straight tube, coil and exchanger-bundle requirements instead of relying on a single general-purpose tube description.
