IN-TUBE MOLE FOR INSPECTING QUALITY OF EDGE WELDS |
摘要 |
FIELD: inspection of edge welds. ^ SUBSTANCE: unit of chambers is made in form of set of separate detectors disposed in plane of cross-lateral section of pipeline uniformly along circle and in symmetry to longitudinal axis of pipeline. Detectors are capable of simultaneous panorama-oriented reception of reflected flux of panorama-oriented X-ray radiation. Planes of set of chambers and of X-ray radiation source are disposed at both sides of plane formed by contact circle of edges of pipe being joined by weld within 4-5 mm. They stay aside it equidistantly from the contact surface along axis of pipeline. Ring-shaped head is made in form of trapezoid to provide angular panorama flux to X-ay radiation directed onto edge weld in such a way that angle of radiation of X-ray flux would equal to angle of reflection from structure of material of weld seam. The second position detector is disposed between planes of unit of chambers and panorama-directed radiation source, namely, in plane brought into coincidence with plane formed by edge of welded pipes. ^ EFFECT: reduced labor input; improved safety; increased precision of positioning. ^ 2 dwg |
