They are designed for heating and cooling liquid and gas aggressive media and constitute an apparatus with a floating head, providing one pass for aggressive medium and multiple passes for inert atmosphere.
A tube bundle enclosed inside a metallic housing comprises tubes made of graphite-reinforced plastics or constructional graphite treated with special structure, tube sheets and cross baffles made of constructional graphite treated with special structure. The standard version of the tube bundle is assembled from tubes made of graphite-reinforced plastics or constructional graphite treated with special structure, with a 37 mm outside and a 26 mm inside diameter. By agreement with the customer the tubes may have different outside and inside diameters.
Tubes inside the tube sheets are arranged at the corners of equilateral triangles. Dividing chambers made of impervious graphite are attached to the tube bundle from both sides by means of gaskets. The aggressive medium is supplied and discharged through the chambers.
The supports of the apparatus are welded to the housing at the mounting location, visit our website to view detailed.
The heat exchange surface of the apparatus depends on the housing’s diameter, the number of tubes arranged, their diameter and effective length.
