Encapsulation System and Kit for a Length of Pipe Disposed Underground

摘要

A kit for encapsulating a length of pipe features first and second foam sections cooperatively shaped to form a cavity with open ends in a working configuration of the foam sections for receiving the length of pipe therein. A foam lower in density than the material of the foam sections fills an unoccupied space in the cavity, providing cushioning for the pipe in the cavity such that movement is permitted and stress on the pipe is reduced. The foam sections feature cooperating ridges and grooves at mating faces of the respective section which are on either side of a channel that cooperates with the channel of the other section to form the cavity. The ridges and grooves when mated hold the foam sections in fixed relation to one another. Also, the foam sections feature passageways such that the cavity is accessible from outside the foam sections in the working configuration thereby facilitating connection apparatus such as for cathodic protection equipment.

主权项

1. A kit for encapsulating a length of pipe which is disposable underground in a subterranean environment and has a pre-specified diameter, the kit comprising:
elongate first and second foam sections extending in a longitudinal axis along the length of pipe that are shaped to cooperatively form a longitudinally elongate cavity with open longitudinal ends in a working configuration of the foam sections for receiving the length of pipe in said cavity so as to enclose the length of pipe around its full circumference thereby shielding the length of pipe, wherein one of the foam sections defines a bottom covering usable for positioning beneath the length of pipe and one of the foam sections defines a top covering usable for positioning over the length of pipe.
