US 9,175,799 B2 · System and method for modular repair of pipe leaks

Abstract

A modular pipe repair enclosure system includes first and second enclosure portions, and an enclosure attachment device. The first and second enclosure portions create an enclosure around the pipe for covering leaks. The enclosure has three openings for accommodating the pipe. The first and second openings are arranged at an angle of 180 degrees with respect to each other, and at an angle of 90 degrees with respect to the third opening, such that a straight line section of pipe may be accommodated by the first and second openings, an elbow section of pipe by the first and third openings, and a T-section of pipe by the first, second, and third openings. The system may further include a blank, for closing one of the openings, for use with a straight or elbow section, and a sleeve, for reducing the inner diameter of an opening, for accommodating pipes of different diameters.

Claims22

Dependent claims

A modular pipe repair enclosure system for repair of one or more leaks in a pipe, comprising:

a first enclosure portion;
a second enclosure portion;
an enclosure attachment device, for securing the first enclosure portion and the second enclosure portion;
and
a strongback clamping unit, the strongback clamping unit being disposable around the pipe, being configured for connection to the first enclosure portion and/or the second enclosure portion and having a strongback holder configured for holding a strongback rod for enhancing structural integrity of the pipe,
wherein the first enclosure portion and the second enclosure portion are so configured as to be disposable around a pipe so as to create an enclosure around the pipe and a void portion, the void portion constituting a void between the enclosure and the pipe and being for covering one or more leaks in the pipe, and the enclosure including three openings, each of the three openings being configured to accommodate the enclosed pipe.

3 more elements

A method for repair of one or more leaks in a pipe, using a modular pipe repair enclosure system, the modular pipe repair enclosure system including:

a first enclosure portion;
a second enclosure portion;
an enclosure attachment device, for securing the first enclosure portion and the second enclosure portion;
a strongback clamping unit, the strongback clamping unit being disposable around the pipe, being configured for connection to the first enclosure portion and/or the second enclosure portion and having a strongback holder configured for holding a strongback rod for enhancing structural integrity of the pipe;
and
a securing device, for securing the strongback clamping unit,
wherein the first enclosure portion and the second enclosure portion are so configured as to be disposable around a pipe so as to create an enclosure around the pipe and a void portion, the void portion constituting a void between the enclosure and the pipe and being for covering one or more leaks in the pipe, and the enclosure including three openings, each of the three openings being configured to accommodate the enclosed pipe, and
wherein the first and second enclosure portions collectively include at least one injection point, configured for communication with the void portion and for injecting sealant through the injection point into the void portion, and
the method comprising:
disposing a first enclosure portion around a pipe;
disposing a second enclosure portion around the pipe, so as to create an enclosure around the pipe and a void portion, the void portion constituting a void between the enclosure and the pipe, and the enclosure including three openings each configured to accommodate the enclosed pipe;
securing the first and second enclosure portions, using an enclosure attachment device;
injecting sealant through an injection point of the first and second enclosure portions into the void portion;
connecting a strongback clamping unit to the first and second enclosure portions;
installing a strongback rod in a strongback holder of the strongback clamping unit;
and
securing the strongback clamping unit, using a securing device,
wherein the void portion covers a leak in the pipe.
