Abstract
In some implementations, an injectable flange gasket includes a plate having two parallel surfaces, each of the two parallel surfaces having an perimeter, the plate also having an outer edge between the perimeters of the parallel surfaces, the outer edge being about perpendicular to the two parallel surfaces, at least one groove in only one of the two parallel surfaces, the groove being continuous and the plate also having a hole that extends from a wall of the groove and through the outer edge of the plate.
Claims17
An injectable flange gasket comprising:
- a disk having two parallel surfaces, each of the two parallel surfaces having a perimeter, and the disk having an outer edge between the perimeters of the parallel surfaces, the outer edge being about perpendicular to the two parallel surfaces;
- at least one groove in only one of the two parallel surfaces;
- a hole that extends from a wall of the groove and through the outer edge of the disk;
- a second hole in a center of the disk that passes through the disk between the two parallel surfaces and the second hole being about perpendicular to the two parallel surfaces;
- and
- a boss on the outer edge of the disk at an exterior end of the second hole,
- wherein the groove is continuous around the second hole.
An injectable flange gasket comprising:
- a plate having two parallel surfaces, each of the two parallel surfaces having a perimeter, the plate also having an outer edge between the perimeters of the parallel surfaces, the outer edge being about perpendicular to the two parallel surfaces;
- at least one groove in only one of the two parallel surfaces, the groove being continuous;
- a hole that extends from a wall of the groove and through the outer edge of the plate;
- and
- a boss on the outer edge of the plate at an exterior end of the hole.
A method of repairing a leak in a pipe flange, where in a flange gasket includes a plate having two parallel surfaces, each of the two parallel surfaces having a perimeter, and an outer edge between the perimeters of the parallel surfaces, the outer edge being about perpendicular to the two parallel surfaces, at least one groove in only one of the two parallel surfaces, the groove being continuous, a plurality of bolt holes in the plate, the bolt holes passing through the plate between the two parallel surfaces and being about perpendicular to the two parallel surfaces, and a hole that extends from a wall of the groove and through the outer edge of the plate, the method comprising:
- placing the flange gasket between flanges of two pipes, the flange gasket further comprising a boss on the outer edge of the plate at an exterior end of the hole;
- placing bolts through each of the bolt holes;
- placing nuts on an end of the each of the bolts;
- tightening each of the bolts;
- and
- injecting sealant into the hole.
