In-Trench Roller

Utilising the same design of &#;Vee&#; formation rubber coated rollers as the Free Standing Roller, the In-Trench Roller is mounted on a trench brace that is adjustable from 0.5 metre to 0.9 metre. Extensions are available to accommodate wider excavations. The In-Trench Roller can be positioned at any angle or point on the brace to enable the pipe to be guided in a trench for all insertion techniques.

The In-Trench Roller is available to suit pipes in the size range 63mm to 355mm.

The amount of movement to be taken up by the piping and any device incorporated in it can be reduced by &#;cold draw&#;. The total amount of expansion is first calculated for each section between fixed anchor points. The pipes are left short by half of this amount, and stretched cold by pulling up bolts at a flanged joint, so that at ambient temperature, the system is stressed in one direction.

When warmed through half of the total temperature rise, the piping is unstressed. At working temperature and having fully expanded, the piping is stressed in the opposite direction. The effect is that instead of being stressed from 0 F to +1 F units of force, the piping is stressed from -½ F to + ½ F units of force.
In practical terms, the pipework is assembled cold with a spacer piece, of length equal to half the expansion, between two flanges. When the pipework is fully installed and anchored at both ends, the spacer is removed and the joint pulled up tight (see Figure 10.4.3).
