Abstract
Methods and apparatuses of joining a first pipe and a second pipe by injecting a pipe joining material into an interstitial space between abutting surfaces are provided. The methods and apparatuses may use a hollow fitting into which pipe ends may be inserted
Claims21
A method of joining an end of a first pipe and an end of a second pipe, the end of the first pipe having an outer annular end surface, the end of the second pipe having a pipe receiving opening, an interior abutment surface positioned spaced inwardly from the pipe receiving opening, and an interior end surface between the interior abutment surface and the pipe receiving opening, the method comprising:
- (a) inserting the end of the first pipe into the end of the second pipe such that the outer annular end surface abuts the interior abutment surface, wherein a groove is positioned between the interior abutment surface and the pipe receiving opening, the groove comprising an open annular region between an outer surface of the first pipe and the interior end surface;
- and,
- (b) utilizing an injection passage that extends from an outer surface of the second pipe to an inner surface of the second pipe wherein the groove is in flow communication with an outlet end of injection passage to inject joining material into the groove.
A method of connecting first and second parts of a piping system utilizing an injection tool having an actuator, the method comprising:
- (a) inserting an end of the first part into an open end of the second part wherein an interstitial space is provided between an inner surface of the second part and an outer surface of the first part;
- (b) providing an injection tool having an actuator, the actuator being calibrated such that each actuation of the actuator ejects a volume of pipe joining material that is equal in volume to at least a third of a volume of the interstitial space;
- (c) positioning the injection tool in flow communication with the interstitial space;
- and,
- (d) actuating the actuator up to three times to fill the interstitial space with pipe joining material.
