Professional Stainless Steel Tubing SolutionsReal TeCarve products for HVAC & heat exchange applications:
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.
Discover more stainless steel tube and pipe options that complement your selection. Our linked products help you find the right material, shape, and specification for every industrial need. Whether you’re seeking seamless precision, welded strength, or specialized forms — we’ve got you covered.
Tube options can be selected for chilled-water, hot-water and other closed-loop HVAC pipework.
Dimensions and material condition can be specified for boiler coils and formed heating or cooling circuits.
Consistent outside diameter and wall thickness support assembly in shell-and-tube exchanger bundles.
Grade and surface selection can account for moisture, condensate and the circulating fluid.
Straight lengths, coils and custom dimensions can be coordinated with equipment manufacturing drawings.
Tube formats can be matched to condensers, evaporators and heat-recovery units within the specified system design.

Dual non-destructive testing on every heat exchanger tube. Factory test benches rated up to 20–30 MPa with automated 5–10 second pressure holding.
Every heat exchanger tube lot is 100% covered by flattening, flaring (expansion) and bending tests; welded tubes also get a reverse flattening test, so tubes will not crack during tube-sheet insertion and expansion. Intergranular corrosion testing (ASTM A262 Practice E / A) is available on request.
Exported with standard EN 10204 3.1 MTC. Flexible trial orders from 100–300 kg support equipment repairs, prototypes, and OEM replacement batches.
Supplied from our partner factories in Foshan & Wenzhou. Customer names withheld.
