Abstract

The plant is used esp. with coating stations for pipes connected together via spigot and socket joints; and includes a cylindrical furnace open at one end and with an axial core assembled from infrared (IR) radiant heaters. The core is surrounded by a cylindrical casing made of thermal insulating material and leaving an annular gap round the core, the pipe end being inserted in the gap. The axial length of the casing pref exceeds the axial length of the core. The IR heaters pref. deliver 60% of their energy at 2-5mu m wavelength. The furnace can pref. be adjusted vertically on a trolley, and the pipe being heated on its ends is pref. located on a wagon. A sensor is pref used to control the temp in the furnace. Pipes are connected together via sliding joints and are used to carry hot fluids; their joint surfaces are coated by a material with a low coefft. of friction and resisting heat e.g. a fluorinated resin. Process ensures that smooth coatings are obtd.
