ABSTRACT:
A coil of tubing can have either adjacent tubes or tubes with a space therebetween. To hold the tubes in place a material such as an adhesive can be placed across the top of the coil, on the bottom of the coil or both to hold the coil in place. The material can also envelope the coils such that the coils are banded. The coils may have a length of a straight portion of tubing prior to the coil beginning and an angled portion on the inside diameter for inserting or extracting a product in the tubing which may be similarly retained. The tubing may be coiled by insertion between two templates. The templates have injection ports for inserting material to hold or encase the tubing. Thus the tubing may be inserted in the templates, a material to hold the tubing in the coiled position inserted and the coiled tubing removed from the templates ready for use in their coiled position with the material on the tubing holding the tubing in the coiled position.
