nor the salts from evaporation adhere, resulting in the life of the external fins being extended by three to five times when compared with the life of a unit without coating. Although theplant is new, andparticularly developed for finned tube applications within Europe, there are plants in the USA that have been running in reduced scale an almost identical process for several years.

Tube Supply International Ltd recently installed new plant in the UK capable of applying an electrophoretic coating to closely pitched fins (8, 9, 10 or 11 fins/inch or even closer) on tubes up to 12.2m long (40ft). The electrophoretic process ensures that an even coating of a chemically resistant paint completely covers the finned and bare tube outer surfaces, even down to the fin base. This chemically resistant paint (PPG paint) has a very smooth external surface to which neither the fouling layer

Corrosion of the fins leading to blocking of the airside flow in air-cooled heat exchangers is one of the greatest problems in their operation and maintenance. As air passes over the lower rows of finned tubes it is heated, and corrosive deposits of the salts in solution form on the fins themselves. Along with the salts, the air also carries dirt and dust and possibly small concentrations of chemicals.

Blocked and fouled fins reduce the heat exchanging efficiency of the tubes.

PREP tool for socket welding Asahi/America, Inc, an expert in thermoplastic fluid flow technologies, has introduced the socket welding PREP tool for removal of oxidation on thermoplastic pipe and fittings before welding.

The new PREP (peel, remove, edge and plane) tool offers three-in-one convenience to quickly prepare a pipe before socket welding by removing the natural oxidation that occurs on polyolefin thermoplastics (PE and PP). Using the tool, the outside layer of the pipe is easily removed, the edge of the pipe is bevelled to ensure easy insertion into the socket fitting, and the face of the pipe is planed to straighten uneven cuts. An added benefit of this one-step process is the marking of the desired insertion depth.

The PREP tool features maintenance- free operation and can reduce overall piping system installation time. The tool is in accordance with DVS and ASTM
