Seamless Corrugated Tubes
Structurally rigid stainless steel tubes featuring engineered helical corrugations that force boundary-layer turbulence, significantly enhancing convective heat transfer efficiency while maintaining straight-line integrity under high-pressure conditions.
Rigid Corrugated Tubing Engineered for Heat Transfer
Rigid corrugated stainless steel tubes are highly engineered piping components featuring helical or annular indentations formed along the longitudinal axis of the tube wall. Unlike pliable corrugated hoses used for routing, these tubes are structurally rigid and maintain their straight-line integrity under high-pressure conditions.
The precise geometric profile of the corrugations is designed to disrupt laminar fluid flow, forcing boundary-layer turbulence. This engineered turbulence significantly enhances convective heat transfer efficiency while maintaining the mechanical strength and durability of a standard structural tube.
Available as straight corrugated heat exchange tubes in lengths up to 12 m, precision cut to match shell-and-tube bundle and tube-in-tube heat exchanger requirements.
Key Engineering Advantages
Enhanced heat transfer
Internal ridges continuously break the thermal boundary layer, converting laminar to turbulent flow and increasing heat transfer 2 to 3 times over smooth bare tubes.
Fouling reduction
Induced turbulence creates a continuous scrubbing action along the inner wall, drastically minimizing scaling, sedimentation and particulate fouling.
Thermal expansion
The corrugation profile acts as a continuous micro-bellows system, absorbing thermal shock and mitigating longitudinal expansion stresses.
Footprint reduction
Higher convective thermal efficiency allows for more compact equipment designs and smaller heat exchanger footprints.

Send an enquirySeamless Corrugated Tubes — common questions
How much does corrugation improve heat transfer?
The uneven internal surface induces turbulence, increasing the heat transfer coefficient and overall exchanger efficiency by roughly two to three times compared with plain tube.
How does the corrugated profile accommodate thermal expansion?
The corrugation profile acts as a continuous micro-bellows system along the rigid tube, absorbing thermal shock and mitigating longitudinal expansion stresses without compromising straight-line structural integrity.
What lengths are available?
Straight corrugated heat exchange tubes are supplied in lengths up to 12 m, cut to match shell-and-tube bundle or tube-in-tube exchanger requirements.
Is the tube seamless before corrugation?
Yes. The base tube is seamless, so there is no longitudinal weld to fatigue under cyclic loading or pulsating flow.
