A water main tapping device and method includes a saddle body including an arcuate portion between a first end and a second end, wherein the saddle body includes a saddle opening at a location between the first end and the second end, and a corporation stop body formed integrally with and extending from the saddle body. The corporation stop body includes a base with an inlet cavity in fluid communication with the saddle opening, a housing extending from the base and having a valve cavity in which a rotatable valve is positioned and which is in fluid communication with the inlet cavity, and a connector end extending from the housing and including an outlet in fluid communication with the valve cavity.

An assembly for generating electrical power from a fluid flow being installable to a fluidic conduit comprising a fluid, the assembly comprising a turbine for generating power from the fluid flow, the turbine provided within a turbine body, a connecting member having a proximal portion attached to a distal portion of the turbine body and a distal portion comprising a cap, a separate enclosure for housing the turbine and turbine body, the enclosure slidably receiving the connecting member through a distal portion, the cap of the connecting member being securable to the enclosure. The enclosure is connectable to a valve member, the valve member and the enclosure for provision external to the fluidic conduit comprising the fluid.

Embodiments of the invention relate a valve fitting milling system and method for use with transmission pipes. One embodiment relates to a milling adaptor used with a valve housing having a temporary gate extending about the pipe and a mill. The milling adaptor includes a main adaptor plate removeably connected to the valve housing which defines at least one milling slot; a sliding gate cutting adaptor movably contacts the main adapted plate and defines at least one cutting hole; a cranking rod engages the sliding gate cutting adaptor and moves the sliding gate cutting adaptor with respect to the main adaptor plate; and a top retainer track removable connected to at least the main adaptor plate. The mill engages at least the sliding gate adaptor and mills a cross-cut hole in the pipe to receive a valve therein.

A machine includes a tool housing defining a housing cavity; a first tool coupled to a first linear drive mechanism, the first tool linearly repositionable along an axis by the first linear drive mechanism about and between a first retracted position and an extended position, the first tool positioned within the housing cavity in the first retracted position, the first tool positioned external to the housing cavity in the extended position; and a second tool coupled to a second linear drive mechanism, the second tool linearly repositionable along the axis by the second linear drive mechanism about and between a second retracted position and a sealing position, the second tool positioned within the housing cavity in the second retracted position, the second tool positioned external to the housing cavity in the sealing position.

In embodiments, a hot tap clamping system comprises a clamp which fits over and secures against a pipe, an actuator interface, an actuator operatively in communication with clamp, and a hot tap assembly. In a further embodiment, a system for sealing a flowline with a metal seal after hot tapping comprises a sealer, a hot tap drill/plug running tool, and a metal seal plug which is typically configured for use in sealing a flowline, e.g. a pipe, with a metal seal after hot tapping where the metal plug seal is inserted into the pipe and engages with and seals as a hot tap.

In a snap tap forming method, a partition wall formed along a curvature of a water pipe outer peripheral wall surface is brought into hermetical pressure contact with the water pipe outer peripheral wall and is mounted on the outer peripheral wall at a position corresponding to an inflow opening portion of a gate valve and at which a snap tap of the water pipe is formed. A center drill guide small hole aligned with the snap tap axis is drilled in a center portion of partition wall. A drilling machine inserted in a water flow sleeve of the gate valve is inserted into the aforementioned small hole. A water diverting port is formed in the partition wall and a peripheral wall of the water pipe using a core drill by advancing the drilling machine while estimating a drilling center. Then the drilling machine is removed from a water flow passage in the gate valve, and the snap tap is connected to the water diverting port by a snap tap attaching tool.
