Abstract

Heating system for pipes, in which heating, for example to melt ice, is carried out by conducting electric current through resistance lines, which lines pass into ducts 2 in a plastic strip 5 which is attached to the pipe by pressing the plastic edges 6 of the plastic strip around the pipe. <IMAGE>

Description

469 535 2 Kanaler i vilka motståndsledningar kan dras kan göras ovanpå ett konventionellt rör genom intryckning av en plastremsa 5 såsom visas i figuren. Kanterna hos plastremsan trycks helt enkelt runt röret. Channels in which resistance lines can be drawn can be made on top of a conventional pipe by depressing a plastic strip 5 as shown in the figure. The edges of the plastic strip are simply pressed around the tube.

Motståndet, skyddet och konstruktionen hos ledningarna kan i allmänhet varieras efter användning.The resistance, protection and construction of the wires can generally be varied according to use.

Under installationen är det i allmänhet lämpligt att placera kablarna under rörets centrum för att förbättra värmeled- ningsförmågan.During installation, it is generally advisable to place the cables under the center of the pipe to improve the thermal conductivity.
