ASTM B111 / ASME SB111 UNS C70600 Copper Nickel 90/10 Low Finned Tube for Oil Cooler
Low finned tubes come in different fin geometries to suit specific applications. The most commonly used types include plain fins (straight fins without any patterns)， spiral fins (fins in a helical pattern along the tube)， and longitudinal fins (fins running parallel to the tube axis). Each fin type offers different advantages in terms of heat transfer performance and resistance to fouling.
Low finned tubes are typically manufactured using processes such as extrusion， roll forming， or embedded fin techniques. Extrusion is the most commonly used method， where fins are formed by squeezing the tube material through specially designed dies. Roll forming involves passing a flat strip of material through a set of rollers to create fins， which are then wound around the tube. Embedded fin techniques involve bonding separate fin strips onto the tube surface.
Benefits of Low Finned Tubes
1. Offers 2.5-3 times the external surface area of bare tube
2. Enhanced heat exchanger efficiency means less tube is required to accomplish the same heat transfer as a bare tube
3. Low finned tube can increase the performance of an existing exchanger without the difficult and expensive task of building new shells etc
4. Reduced space and weight can be extremely valuable in offshore production or high elevation distillation columns. Low finned technology can transform large shell and tube exchangers into compact heat exchangers
