| 20100186826 | Remote Tapping Method and System for Internally Tapping a Conduit - Disclosed is a method, system and apparatus for use in remotely and internally tapping a conduit. The method is performed, at least partially, by an automatic mechanism or robot configured to effectively perform the tasks and various steps of the method. The method includes the steps of: (a) lining a conduit with a liner; and (b) inserting an automatic mechanism into an internal portion of the liner, wherein the automatic mechanism (i) locates a service tap connection point; and (ii) at least partially engages a fitting device within an internal surface of the service tap entry portion, thereby providing fluid communication between a service tap internal passageway and an internal portion of the liner. An automatic mechanism, a fitting device and an insert element are also disclosed. | 07-29-2010 |
| 20090127749 | Conduit Expansion Method - Disclosed is a conduit expansion method, including: inserting a liner conduit formed from a rigid, polyvinyl chloride material at least partially within a host conduit; circulating fluid within an inner area of the liner conduit; and injecting fluid into the inner area of the liner conduit; wherein the liner conduit at least partially expands within the host conduit. | 05-21-2009 |
| 20090038703 | SYSTEM AND METHOD FOR CONDUIT REPARATION - Disclosed is a system and method for conduit expansion for use in expanding a liner conduit within a host conduit. The system includes injection hardware positioned on a first end of the liner conduit and the host conduit, and distal end cap hardware positioned on a second end of the host conduit and liner conduit. Both the injection hardware and the distal end cap hardware are in communication with a control mechanism for use in monitoring and/or controlling the operating parameters of the system. | 02-12-2009 |
| 20080257604 | Conduit, manufacture thereof and fusion process therefor - A method for fusing a first conduit section to a second conduit section, each including at least one bell portion with a first end and a second end and having a bell portion inside dimension greater at the second end of the bell portion than at the first end of the bell portion. The method includes: heating and melting at least a portion of each of the second end of the bell portion of the first conduit section and the second end of the bell portion of the second conduit section; and fusing the first conduit section and the second conduit section by engaging the second end of the bell portion of the first conduit section with the second end of the bell portion of the second conduit section, thereby creating a fused conduit system having a fused joint area. | 10-23-2008 |
