Ultrasonic automatic nondestructive testing equipment and system for high-temperature hydrogen production converter tube

Abstract

The invention discloses ultrasonic automatic nondestructive testing equipment and system for a high-temperature hydrogen production converter tube, and the equipment comprises a pipeline crawling equipment main body, and the top end of the pipeline crawling equipment main body is provided with a rotating cover plate. A storage battery, a control mainboard, a wireless transceiver and a storage cardare arranged in the crawling equipment body, the wireless transceiver is wirelessly connected with a computer client, a detection sleeve is arranged at the output end of each first electric telescopic rod, a laser range finder is arranged on the front side of each detection sleeve, and a high-frequency ultrasonic excitation receiving collector is arranged on the inner side of each detection sleeve. Positive and negative motors are arranged on the back sides of the two edges, adjacent to the rotary cover plate, of the pipeline crawling equipment body, lead screws penetrating through the side wall of the pipeline crawling equipment body are arranged at the output ends of the two positive and negative motors, the two lead screws are sleeved with lead screw nuts, and clamping sleeves are arranged at the output ends of the two second electric telescopic rods. And the pipeline defect detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to an ultrasonic automatic non-destructive testing device and system for a high-temperature hydrogen production reforming furnace tube. Background technique [0002] High-temperature reformer tubes for hydrogen production are widely used in petrochemical enterprises. In order to obtain the greatest economic benefits, the economic scale of foreign oil refineries is generally above 15 Mt / a. In order to meet the requirements of modern refineries for high reliability, high flexibility, low cost, and low consumption of hydrogen production units, large-scale hydrogen production units have become a trend. According to incomplete statistics, by 2005, there were more than 60 sets of devices with a scale above 80dam3 / h, distributed all over the world. At present, foreign companies with large-scale hydrocarbon steam conversion hydrogen production technology mainly include Technip in France, Lurgi, Linde and Uhde in Germany, and Flowserve in...

AI Technical Summary

Problems solved by technology

The advantage of the detection equipment and method is that it can quickly and accurately identify furnace tubes with serious damage, but it is not necessary to detect furnace tubes with less serious damage, smaller damage size, circumferential cracks, or other types of damage. Inaccurate and effective, and the criteria for life rating evaluation are too vague
