There is disclosed a conduit inspection apparatus of a type adapted to be located within and transported along a conduit such as a duct, and a method of inspecting a conduit.In one embodiment, the conduit inspection apparatus (10) comprises a body (18) adapted for location within a conduit such as a duct (14), a centralization assembly (16) for centralizing the body (18) within the duct (14), a transportation assembly (20) for transporting the body (18) along the duct (14), and a data coupling (...

A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.

A collapsible pig attached to the end of a tubing and having a seal to the bore of a pipeline for pulling the tubing into the pipeline at up to a predetermined pressure differential across the seal and while allowing the fluid in front of the pig to flow into the end of the tubing without pressure restriction, alternately having reversed flow from within the tubing exit the end of the tubing through jetting nozzles, and having the seal collapse at a pressure differential higher than the predeter...

A smoothing device, according to the present invention, is used to perform smoothing in a conduit line, or the like. The smoothing device has a fluid pressure motor with a cutter attached to its output shaft and guide rollers for guiding the smoothing device in the longitudinal direction of the conduit line. Prescribed ones among the guide rollers are relatively movable in the radial direction of the conduit line by fluid pressure cylinders, springs, or the like, and pressed against the inner wa...

A protector for protecting a cleaning hose inserted into an end of a generally cylindrical sewer pipe and withdrawn therefrom during cleaning with contact against an end of the sewer pipe includes a body having a generally cylindrical insert portion dimensioned to be received in the end of the sewer pipe and a flange portion. The flange has a radial width, relative to a central axis of the pipe, greater than a wall thickness of the pipe. A back surface of the flange portion is held against an en...

In order to provide an improved pipe washing apparatus guaranteed to be free of the wearing and/or breaking of nozzle shaft, it is provided with a nozzle support to be fixed to the end of a washing hose, which is to be inserted in a pipe to be washed inside, a cylindrical nozzle rotatably fixed to the nozzle support and a nozzle guide member fixed to the forward end of the nozzle for guiding the nozzle along the inner circumference of the pipe. The nozzle support has a longitudinal water channel...

A cleaning tool includes a support substrate, a cleaning member, a shaft member where the cleaning member is connected to one end of the shaft member detachably, and support member mounted to the a support substrate for supporting the one end of the shaft member with the cleaning member so that the shaft member and cleaning member are oscillated freely in a direction which intersects perpendicularly to an axial direction of the shaft member. The cleaning tool may be used to clean an end surface ...

A method of scarifying an interior surface of a pipe to remove contaminants and corrosion products, using a vehicle carrying an attached principal arm that is pivotable and that has a nozzle assembly at a distal end thereof. The nozzle assembly has a plurality of nozzles mounted at free ends of associated nozzle branches, the nozzle branches being rotatable or capable of oscillation about a distal end of the principal arm. One of the nozzle branches and the principle arm are extendible to positi...

An assembly for rotating and axially directing a high pressure spray hose and spray head to clean residue from the bores of thermal transfer tubes. The assembly includes a number of subassemblies that are concentrically aligned and mounted to rotate in synchrony and direct a high-pressure hose and spray head. A hose cleaning subassembly washes and/or brushes the hose exterior with a low-pressure spray. A hose drive assembly controls axial hose movement via driven gears and chains and four polyur...

The invention relates to an apparatus for flushing a hydraulic small-diameter pipe system or the like. Two pressure accumulators (33a and 33b) are arranged at one end of the pipe system (20), connectable alternately to the pipe system and to a tank (39), for receiving a volume of liquid corresponding to volumes of gas and liquid, respectively, which are alternately introduced into the opposite end of the pipe systems for filling the pipe system with alternating columns (42, 43) of flushing liqui...
