Abstract: A method for connecting piping includes securing a first piping portion to a base. A second piping portion is secured to a rotating portion. The second piping portion is then rotated. While the second piping portion is rotating, the second piping portion is inserted and driven through the first piping portion. A portion of the first piping portion disconnects from the remainder of the first piping portion. After this disconnection, a rotation of the second piping portion is stopped. A solid weld is formed between the first piping portion and the second piping portion.

Abstract: A method of installing a cable or conduit into at least one plastic pipe of a fluid carrying pipeline system, comprises attaching a first saddle fitting at a first location on said plastic pipe by electro-fusion, opening the pipe at the first location, introducing the cable or a pull body through the saddle fitting into the pipe towards a second location or retrieving at least part of the cable or a pull body introduced at a second location, and pulling the cable directly or by means of the pull body through the pipe. This allows installation of a cable without turning off the fluid supply.

Abstract: A plumbing tool includes an elongated hollow shaft and a resilient member attached to the shaft adjacent a shaft end. The resilient member extends radially outward and is sized to closely fit within a pipe inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. A valve is then passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the value is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.

Abstract: A self-piercing radiator drain valve which is implemented in a radiator requiring the coolant therein to be drained, particularly a radiator having no integrated drain valve. A radiator foot has a blind bore. A self-piercing valve body including a piercing tip and a resilient seal is threadingly driven into the blind bore to cause the piercing tip to penetrate the bore end wall and enter into a coolant reservoir tank, thereby providing a valve orifice for draining the tank. The seal provides coolant tight sealing with respect to the valve orifice for the remaining life of the radiator. At any time in the future, coolant draining and refilling can again be performed by unthreading and then rethreading the self-piercing valve with respect to the blind bore, as recounted.

Abstract: In order to free a seized valve, an inspection port is formed in a wall of the valve body and the areas where the valve is seized are determined.

Abstract: A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling nipple attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first drilling nipple by using a first manipulator located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism, until a second drilling nipple is reached. The translating member is attached to a fiber optic conduit. The duct rod and fiber optic conduit are then pulled back or pulled forward through the pressurized gas pipeline by the driving mechanism.
