Steel tubes and pipe

New markets for stainless steel finned tube heat exchangers

positions multiple fins at once. They are claimed to be the only machines that can join any two metals with precision, using a clean, green process. Stainless steel tubes are difficult to fin, especially if they are elliptical, thick walled, or micro bore tubes of 5mm or smaller diameter. As the interference fit is achieved by the fin, all sizes and specifications can be accommodated with ease. The precision of manufacture also produces heat exchanger cores of consistent performance.

in the heat transfer industry for over 40 years, and in that time he has bought, managed and sold a number of successful companies. He has also developed and patented eight related products. Mr Pierce’s original patented linear motor Elfin finning machine is capable of mechanically bonding any two metals. This produces an interference, swaged fit between fins and tubes to form a durable matrix, which extends the surface area of the tubes to dissipate heat or cooling more rapidly, without deformation of the base tubes.

Heat exchangers are used in many industries, including the emerging markets of fuel cell, waste heat recovery and micro power generation – all projected to be multi-million pound worldwide markets in the near future. With specific requirements to deal with corrosive condensates and high temperatures, the use of stainless steel fins on stainless steel round or elliptical tubes, including 5mm small bore, challenges traditional matrix manufacturing methods, to reach required heat transfer requirements.
