< Extruded or drawn fin tube, seamless with two longitudinal opposite fins. Used in boiler wall constructions. Advantages Strong connection between fin and base tube, prevents loosening of fin because of heat stress, oxidization, corrosion etc., use at very high temperatures possible.
< Heat Exchanger. A heat exchanger is a device used to transfer heat between a solid object and a fluid, or between two or more fluids. The fluids may be separated by
< 2016-6-16 · The shell and tube heat exchanger is the most common of various types of unfired heat transfer equipments used in industry. Although it is not especially compact, it is robust and its shape makes it well suited to pressure operation.
< 2012-6-17 · Fin-Tube Heat Exchangers¶ Overview¶ In ACHP, all of the heat exchangers that exchange heat with an air stream are of the fin-tube type. In practice, other types of heat exchangers (shell-tube, microchannel, etc.) are also possible, but they are not included in
< Fin-Tube Heat Exchanger Optimization. 2018-9-25 · Fin-Tube Heat Exchanger Optimization 345 Fig. 1. Straight fin of variable cross section. Both the conduction through the fin cross section and the convection over the fin surface area take place in and around the fin. When the fin temperature is lower than the base. Learn More
< Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins. Finned tubes or tubes with extended outer surface area enhance the heat transfer rate by increasing
< Alibaba.com offers 496 h type finned tube for heat exchanger products. About 9% of these are refrigeration & heat exchange parts, 2% are other refrigeration & heat exchange equipment.

Since 1969, Webco has provided seamless carbon/alloy and welded carbon tubing products for pressure tube applications in petrochemical, commercial fire and water boiler service, and requirements in a variety of other industries. Today, Webco is the only full-line manufacturer of welded boiler
< Condensing Boiler & fin tube: I can't answer your question the way you asked but I would say that any time you do a boiler change, you should do an accurate heat loss on the structure and then measure the radiation. It depends on what factors the designer used for
< The shell and tube have various shapes and design but the basic function of all types are common. The tube diameter should be within proper limit not too small not too large, because small diameter tubes have difficulty in cleaning of fouling but small tubes make heat exchanger economical and compact.
< Bimetallic (E-fin) tubes consist of an inner tube, or liner, and an outer tube, or sleeve. The inner tube may be made from any tubing material and has the same dimensions as standard heat-exchanger tubing. The outer tube is integrally finned and is usually made of aluminum alloy.
< Knowledge about heat exchanger theory, calculations and design is important because of the widespread use of a variety of heat exchangers for industrial use and in everyday life. Industrial heat exchanger types include the most common double pipe heat exchangers, shell and tube heat exchangers, as well as spiral, flat plate, and fin tube heat exchangers.
< "Welded" Fin High frequency welded spiral finned tube is one of the most widely used finned tubes. It is a plain type fin, made by helically winding the fin strip on edge around the tube. The fin is continuously welded to the tube by a high frequency electrical resistance welding process which leaves the tube essentially unchanged
