Integral Low Fin Tubes
Timex Metals is an Integral Low Fin Tubes Manufacturer offering high-efficiency heat transfer tubes designed with an integrally formed finned surface to enhance thermal conductivity. These tubes are manufactured from carbon steel, stainless steel, copper alloys, and titanium, and are ideal for applications in air conditioning, refrigeration, petrochemical plants, power generation, and gas processing units. The external low fins increase the surface area for better heat exchange, while the smooth internal bore ensures unimpeded fluid flow. Produced in compliance with ASTM B111, EN 12451, and ASME SB359 standards, these tubes provide durability, thermal performance, and resistance to scaling and fouling.

Integral Low Fin Tubes find their way in heat exchangers, condensers, and cooling systems where additional heat transfer is necessary. In these cases, G Finned Tubes offer better thermal efficiency without the need for a larger piece of equipment. An unambiguous material and grade table facilitate precise picking and obtaining via a reliable B2B Marketplace to maintain the desired level of performance and adhere to the regulations.
Type of Sub-products

Straight Integral Low Fin Tubes Straight Integral Low Fin Tubes
These tubes feature uniformly spaced fins rolled directly onto the outer surface of a straight tube. They’re ideal for conventional heat exchangers and applications with consistent thermal demands.

U Bend Integral Low Fin Tubes U Bend Integral Low Fin Tubes
Designed for compact heat exchangers, these tubes have integrally formed fins along a U shaped bend, allowing for a reduced footprint and increased surface contact in shell and tube configurations. Commonly used in condensers and evaporators.
