Heating pipe system for embedding in concrete panels comprises single pipe bent to form grid of parallel sections connected at their ends by curved sections which merge into second set of parallel sections crossing first at right angles

摘要

The pipe system is made up of a single pipe (26) which is bent to form a grid of parallel sections (32) connected at their ends by curved sections (38) which merge into a second set of parallel sections (34), also linked by curved sections, (40) which cross the first at right angles and are fixed to them.
