Abstract

The application relates to a steel hot bend orifice roundness calibration system which comprises a hydraulic cylinder with a roundness calibration device and a double-piston rod, a hydraulic control system and a laser measurement and control system for controlling outreach distance and retraction time of the hydraulic cylinder. The laser measurement and control system comprises a laser sensor and a laser measure and control instrument. The laser sensor is arranged on the hydraulic cylinder and used for measuring the distance from the position of the laser sensor to the tube wall. The laser measure and control instrument is connected with the laser sensor and used to send a control instruction to the hydraulic control system depending on the distance measured by the laser sensor. The hydraulic control system is used to control the hydraulic cylinder to calibrate roundness of the orifice according to the control instruction. The application also provides a steel hot bend orifice roundness calibration method. According to the application, the outreach distance and retraction time of the hydraulic cylinder can be accurately controlled and real-time measurement and controlling of the steel hot bend orifice roundness calibration can be realized.

Description

technical field [0001] The present application relates to the technical field of oil and gas pipeline processing and measurement, in particular to a system and method for calibrating the roundness of the mouth of a steel thermally bent pipe. Background technique [0002] After the steel hot-simmering bend is finished, due to the clamping of the nozzle and its internal stress, the nozzle will appear out of round (ie ellipse), resulting in the appearance quality of the bend being unqualified. Nozzle correction processing is required. Usually domestic jacks or hydraulic cylinders are used for round calibration processing. Every time a calibration is performed, a measurement is made with a steel ruler or a micrometer; degree until qualified. Manual calibration and measurement not only has low work efficiency and high labor intensity, but also is prone to human errors and measurement errors. Contents of the invention [0003] The present application provides a system and met...
