Abstract: The protective clutch has a core inside the shell and the transmission of the rotational movement between these occurs by the sleeves which are held in the openings of the shell and the grooves of the core by an elastic spring element. When the protective clutch experiences high torque, the spring element deforms and allows the sleeves to rise from the grooves preventing transmission of the rotational movement from the core into the shell. The magnitude of deformation of the spring elements is limited by the casing which simultaneously prevents the sleeves from escaping from the openings.

Abstract: A method of lining a branch area in a pipeline using an inflatable bladder. The method includes steps of preparing a branch liner with resin and positioning the branch liner in a pipeline, inflating the bladder and running a flow of air and steam through the bladder while monitoring its temperature. After curing of the resin, temperature of the liner is monitored and the bladder is removed only after proper cooling of the liner.

Abstract: A flexible shaft which has a plurality of metal sleeves having a smaller end portion and a larger end portion at opposite ends of the metal sleeve. One of the end portions has a plurality of protrusions whereas the other one has a plurality of apertures capable of accommodating a part of each of the plurality of protrusions. The smaller end portion of is partially inside the larger end portion of the next metal sleeve in the flexible shaft. Each metal sleeve is movably connected to the next metal sleeve using the protrusions and apertures. The apertures are notably larger than the protrusions in lengthwise direction of the flexible shaft which allows two adjacent metal sleeves to be in position where their rotation axes are not parallel.

Abstract: The device is for cleaning the inner surface of a pipe. The device has a spindle arranged to be rotated and having a front end and a rear end between which a plurality of elastic metal blades are attached both in the rotation direction of the spindle and in the direction perpendicular to the rotation direction to clean the inner surface of the pipe. The blades has a shape that is curved at at least two points such that they curve at least once towards the circumferential direction of the spindle and at least once outwards from the circumferential direction of the spindle to prevent the device from getting stuck in uneven pipe systems.

Abstract: The device is for opening up a branch point of a pipe assembly. The device has a tip part arranged to be rotated, in connection with which there is at least one blade, and spring-loaded discs and protrusions which are separate from the tip part and arranged to remain essentially non-rotating as the tip part is rotated.

Abstract: The coating device has a rotatable spindle which has fastening mechanisms for fastening a rotation axle to the spindle. Protrusions are radially protruding from the spindle for spreading the coating substance on the inner surface of a pipe. The protrusions have limiters that limit the coating substance to be spread to the desired layer thickness. The method comprises the steps of bringing, to the pipe to be treated, the coating device fastened to a rotation axle with the pipe, a feeding hose of the coating substance and a camera. The coating substance is fed along the feeding hose to a vicinity of the coating device. The coating substance is spread to an inner surface of the pipe by rotating the coating device and by moving the coating device in a longitudinal direction of the pipe.
