FIELD: pipelines.
SUBSTANCE: crack opening control device is an elastic element in the form of a curved metal plate fixed on the tested structure, which has a crack, moreover, the metal plate has an upper horizontal section and two lateral supporting curved sections, whereas two strain gauges are fixed on the outer and inner surfaces of the upper horizontal section, which are designed to control bending deformations that occur in a horizontal section when opening crack edges, and there is a groove in the lower part of the one of the side curved sections in contact with one of the crack edges, and the lower part of the other side supporting curved section in contact with the other crack edge has a reed support having a width not exceeding the width of the groove, whereas the groove is configured for passing the reed support into it.
EFFECT: improved reliability of crack control in pipes during hydraulic tests, as well as during operation of main pipelines.
