A trailer for staging a pipe lining for in-place installation and curing of the pipe lining has an expandable cover including a roof and side walls. Pipe lining staging apparatus located within the cover can be converted between a collapsed configuration and an expanded configuration. The floor can expand outward from the chassis for holding the staging apparatus in an expanded condition.

Over the hole trailer

A system and method for capturing volatile organic components from a liner curing process for pipes. The system receives steam exhausted from the liner. The steam is used for curing a curable material in the liner, but volatilizes organic components in the resin carried along with the steam. The system removes some water and passes the remaining vaporized constituents through a filter selected to capture the particular volatile organic component from the steam.

An air inversion and steam cure apparatus for installing a flexible resin impregnated cured in place liner in an existing conduit is provided. The apparatus has a low friction seal between a moving liner and the stationary apparatus gland. The gland is operated and adjusted by displaceable members that move substantially perpendicular to the liner being inverted to engage the moving liner as it passes through the gland. No part of the gland extends into the chamber so that once a pre-shaped gland is adjusted, the pressure on the moving liner is not increased. As the liner reaches the distal end, it enters a sample and porting pipe with an exhaust pipe gland and exhaust pipe and is pierced by a rigid porting tool. Steam is then introduced into the liner to cure the resin and is exhausted through an exhaust hose connected to the porting tool. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the existing conduit.
