Abstract: The invention relates to a holding fixture for a pipe-line in a structure in which the operating temperature is markedly different from the ambient temperature and the ends of which in its holding posture can be connected to the pipe-line and to portions of the structure of the building by fastening fittings and to devices for registering any change in length occurring as a result of a change in the temperature of the medium flowing through the pipe-line and converting it into a change in the length of the holding fixture.

Abstract: A tube or pipe undergoing thermal expansion when used and being part of a pipeline system experiences lateral and longitudinal displacements of suspension points in vertical direction. The tube side suspension points are connected to levers pivoted to the tube, the pivot points moving up or down with the tube. The levers are connected further to rods being linked with their other ends to the tube to provide a control displacement as the tube longitudinally expands thereby pivoting the levers such that the thermal expansion displacement of the tube is compensated. Load relief for the rods are additionally provided as well as moment control and compensation.

Abstract: A tube or pipe for the conduction of hot fluid is suspended in the vertical by means of an anchor, pivotally linked to the long arm of a two-arm lever which is pivoted on the tube or pipe and has its second, short arm linked to a pivot-near point of a one-arm lever, and is in line with a rod extending between this one-arm lever at right angles thereto and axially along the pipe or tube to a remote connection point on the tube. The long-arm portion of the one-arm lever is spring-biased; the compression of the spring varies with vertical displacement of the tube or pipe, but the two-arm lever is pivoted by exactly the same amount when the tube is displaced and when, upon expansion, the one-arm lever is pivoted, which pivot motion is transmitted upon the two-arm lever.
