Gaps between fin tube is a common request from our customers.  Long gaps enables the customer to get the tube bent after finning. The gaps are left unfinned so the tube can be bent with no risk to the tube integrity. Small or shorter gaps between fin tube enables long tubes to be supported with no damage to the fin.

Fin tube support can prevent fin from damaging when put fin tubes together when delivered, also can be a support when installing fin tubes on air cooled heat exchangers. If you prefer to safe time during installation of the pipes, you can choose for half pipe supports (HPS) fitted on the tubes or casted zinc rings around the fin at certain distances. Heat exchanger fin tubes in long length with aluminum click support . We can supply different shapes of fin tube supports, available in aluminum material and galvanized zinc steel.

Bimetallic Aluminum Finned Tubes—Extruded Finned Tubes Bimetallic Aluminum Finned Tubes, also named a luminum rolling finned tube , is rolling as a whole by the aluminum tube (also called muff tube), which has the feather of no contact thermal resistance, high strength, thermal shock and mechanical shock, good thermal performance, and considerable expansion heat transfer surface. The heat exchanger with this kind of finned tube is more efficient than the string or around the plate ones. Fabrication Process For composite finned tube, we need to pipe line—— compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging We are a professional manufacturer of aluminum finned tube in China market, with good quality and reasonable prices. In the next article, I will introduce you the normal specifications our customer used for air cooled heat exchanger, air preheater, etc. If you have any interest, please contact with us at finnedtube@163.c...

What kinds of finned tubes are used in air cooled heat exchanger？ The tubes can be of virtually any material available, such as carbon steel, stainless steel, Admiralty brass, or more exotic alloys. The minimum preferred outside diameter is one inch. Some manufacturers sometimes use smaller tubes, but most of the process coolers have tubes which are 1.0", 1.25", or 1.5" OD. The minimum tube wall thicknesses vary with the material. In some cases the design pressure and design temperature of the exchanger govern the minimum thickness. The fins are almost always of aluminum material. The most common type of fin is the helically wrapped, L-footed type . These are used where the process temperatures are below about 350 deg. F. The API specification calls for cast zinc bands at the ends of the tubes to prevent the fins from unwrapping. Some of the better manufacturers also use cast zinc bands at the tube supports. For higher process temperatures, most customers prefer ei...
