Finned tube according to its manufacturing process classification and welding process
Murphy thermal technology, supplier of laser-welded stainless steel finned tube, analyzes finned tube with you:
Finned tube can be divided into longitudinal and radial two basic types from the structural type, other types are the development and deformation of these two types, such as large spiral Angle finned tube close to longitudinal, small spiral Angle finned tube close to radial finned tube shape is round, rectangular and needle. In addition, the fins can be arranged outside the tube, called the outer finned tube; Can also be arranged in the tube, called the inner fin tube or both inside and outside.
Finned tube manufacturing technology can be classified into integral finned tube, high frequency welded finned tube, mechanical connection finned tube and laser welded finned tube, generally, the whole finned tube in the process of production is mainly by casting, mechanical processing or rolling, finned tube and tube as a whole. Welded finned tubes are manufactured by brazing or inert gas shielded welding. Modern welding technology can connect the fins of different materials together, and can make the fin tube simple, economical, with good heat transfer and mechanical properties, has been widely used. Because the residue in the weld is not conducive to heat transfer and may even cause fracture, it is necessary to ensure the welding quality in the production of such finned tubes.
The high-frequency welded finned tube mainly uses the frequency electrical induction generated by its high-frequency generator. In this way, high temperature can be generated at the contact point between the surface of the tube and the fin, which can be dissolved in a depth range of about 10 m, and then pressurized to connect the fin with the tube as a whole. No flux, no solder, easy to manufacture, high productivity, good heat transfer and mechanical properties. This is an ideal type of finned tube for the majority of users to understand and use.
Finned tubes usually have three types: inlay type, shell type, winding type, or string type. It is easy to manufacture the wound plate finned tube. The metal belt is arranged around one end of the tube by mechanical or welding method. The metal belt is tightly wound around the outer wall of the tube by the rotating torque of the tube, and the other end is fixed to form the wound plate finned tube. The material can be copper tape, steel tape or aluminum tape.
Murphy thermal technology's finned tube is the use of the most advanced laser welding technology
The perfect combination between fins and tubes improves heat transfer and corrosion resistance, resulting in clean welded finned tube joints and fully straight fins (no ripples).
New material combination and production scope
Our laser finning process allows for a wider size range of tube and fin combinations. The height, thickness and pitch of the fins are feasible beyond any conventional fin process.
In addition, the increased range of tube and fin material combinations (steel, aluminum, copper, titanium) provides new advantages and alternatives for industry.
Price savings, lower energy consumption, lower consumables costs, and increased efficiency have enabled Murphy to offer very competitive prices.
