ELECTROFUSION FITTING AND METHOD OF REPAIRING PIPES

摘要

A fitting for repairing a leaking polymer pipe is provided. The fitting includes a first housing and a second housing that are sized to fit about the pipe. The first housing includes a first coil configured to increase in temperature in response to the application of an electrical current to fuse the first housing to the second housing and the pipe. The second housing includes a second coil on a first end and a third coil on an opposing end. The second and third coils configured to increase in temperature in response to the application of electrical current to fuse the second housing to the pipe. The fitting further includes a first seal coupled to the first housing and a second seal coupled to the second housing. The first and second seal forming a seal that prevents gas pressure from the pipe from interrupting the fusion process.

主权项

1. A fitting for repairing a leaking polymer pipe, the fitting comprising:
a first housing having a first end and an opposing second end with a first body therebetween, the first body having a first interior surface defining a semicircular-shaped first channel, the first channel sized to receive a first portion of a pipe; a second housing having a first end and an opposing second end with a second body therebetween, the second body having a second interior surface defining a semicircular shaped second channel, the second channel sized to a second portion of a pipe; a first coil configured to conduct electrical current disposed within first housing, the first coil having a first portion adjacent the first end, a second portion adjacent the second end, a third portion extending between the first portion and the second portion; a second coil configured to conduct electrical current disposed within the second housing adjacent the second housing first end; a third coil configured to conduct electrical current disposed within the second housing adjacent the second housing second end; a first seal coupled to the first interior surface, the first seal positioned to contact the pipe adjacent the first housing first end and second end, the first seal further having a portion contacting the second housing when the first housing and second housing are coupled; and a second seal coupled to the second housing, the second seal positioned to contact the pipe adjacent the second housing first end and second end, the second seal further having a portion contacting the first housing when the first housing and second housing are coupled.
