Abstract: The device is for curing a coating substance inside a pipe. The device has a flexible shaft inside a duct, an air inlet channel within the duct, a body configured to be attached to the duct, a heat sink in connection with the body and defining a plurality of cooling channels which are in fluid connection with the air inlet channel. The device further has a plurality of light emitting devices configured to be cooled by the heat sink. The device further has an air outlet channel in fluid connection with the cooling channels of the heat sink. The air outlet channel exits the body from the same side of the body as the air inlet channel enters the body.

Abstract: The cleaning device is for cleaning the inner surface of pipes. The cleaning device has two sleeves on a flexible shaft and chains extending between the sleeves. A forward end sleeve is not attached to the shaft and is biased by a spring on the shaft. The cleaning device can be adapted to different pipe sizes by altering rotation speed of the cleaning device. High rotation speed compresses the spring and moves the chains further away from the shaft to enable cleaning of larger diameter pipes with the cleaning device.

Abstract: A method of reducing a leak or a risk of a leak of a pipe system is disclosed. The pipe system is filled with a composition that includes metal powder and xylenes, and a pressure is applied to the filled pipe system and the pipe system is drained of said composition. Also, the use of a composition for reducing a leak or a risk of a leak of a pipe system is disclosed.

Abstract: The cleaning device is for cleaning the inner surface of pipes. The method is for manufacturing the cleaning device and the use is of a vehicle anti-skid chain for cleaning the inner surface of a pipe. The cleaning device has a sleeve, to which are attached studded chains composed of steel links and surface hardened.

Abstract: A lining drum which has a tubular body having open ends, an inlet for compressed air and an outlet for liner is disclosed. The lining drum has end pieces removably attached to the tubular body for closing the open ends of the tubular body, a rotatable shaft inside the tubular body and a crank for rotating the shaft. An elastic fastener has a first end in operative engagement with the tubular body and a second end in operative engagement with the end piece. The second end is opposite the first end. The end piece is movable between a closed position and an open position by extending the elastic fastener against an elastic biasing force of the elastic fastener. The end piece and the tubular body has a gap defined therebetween when the end piece is in the open position.

Abstract: A device for opening a connection to a lined pipe is disclosed. The device has a body that includes a front end and a rear end and being rotatable about a rotation axis. The device also has a drill head that has multiple cutters for puncturing and enlarging a hole in a liner, and multiple side cutters have at least one cutting edge parallel to the rotation axis. A safety ring is disposed on the body between the drill head and the side cutters. The safety ring has a circular periphery extending beyond the drill head and the side cutters in a direction perpendicular to the rotation axis.
