DEVICE FOR MEASURING AND NONDESTRUCTIVE TESTING OF PIPE LINE MATERIAL Russian patent published in 1999 - IPC

FIELD: measuring and nondestructive testing of materials. SUBSTANCE: device includes cylindrical carrier for sensors made from elastic material; its outer diameter slightly exceeds inner diameter of pipe line. carrier is made in form of radially spring-loaded holders interconnected together and mounted on common flange; each holder is provided with longitudinal recess where sensors are mounted. Recess forms passage together with wall of pipe line which is open on side of tail portion of holder. Front wall of recess has L-shaped form in cross section; lateral walls are provided with plates made from elastic material and arranged over periphery which slightly project beyond peripheral sections of lateral walls; thickness of these walls exceeds thickness of front wall and side plates. Device includes also at least one hermetic housing articulated with carrier. This housing holds information processing and supply unit which are connected with sensors. EFFECT: improved tightness of faying of edges of holders to pipe line wall irrespective of changing profile. 4 cl, 5 dwg
