Adaptor devices, installation guide devices, and methods provide a fluid connection into a conduit section interior of a conduit section of a conduit through a sidewall thickness of a conduit section sidewall of the conduit section. A method includes coupling an installation guide device to the conduit, operating a drill bit device while the installation guide device is coupled to the conduit to cause the drill bit device to move longitudinally to a protrusion distance that is equal to or less than a particular protrusion distance defined by a protrusion stop structure to drill through the sidewall thickness of the conduit to form an access point opening through the sidewall thickness of the conduit into a conduit interior of the conduit, and coupling an adaptor device to the conduit section at the exposed access point opening, to establish fluid communication into the conduit section interior through the adaptor device.

A pipe coupler having a saddle for connecting to a riser adapter for use in an irrigation system to distribute water. A dynamic seal is positioned in a circumferential channel of the riser adapter on the outer surface of a flange or projection that is positioned into the circular mount of the saddle. In response to water pressure against the dynamic seal, the dynamic seals the connection between the riser adapter and the saddle by sealing against the annular sealing face on the inner circumference of a circular mount of the saddle. The dynamic seal is an O-ring in preferred embodiments.

A boring machine for boring a part of a fluid pipe in an uninterrupted flow state, includes: a shaft member having a leading end to which a cutter is attached; a drive mechanism configured to rotate the cutter and the shaft member around the shaft of the shaft member; and a forward and backward moving operation mechanism configured to move the cutter and the shaft member forward and backward in the axial direction of the shaft member by a handle that is manually rotated. The forward and backward moving operation mechanism is further configured to switch a feed amount of the cutter and the shaft member in the axial direction between at least two different feed amounts according to a rotational amount of the handle.

The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of interest is removed to be forwarded for analysis. Such a clamp (7) has means to isolate the pipe (1) from the external environment, introduce the tool (3) and remove the same with the sample, also allowing tightness repair of the pipe (1).
