HUATEC 320kV Ndt X Ray Pipeline Crawlers

HUATEC HDR-01 DR Ndt X Ray Equipment Ndt Pipeline X-Ray Crawler Pipeline Crawler X-Ray Machine

1. Overview

With the continuous development of science and technology, testing equipment is constantly updated. Our company closely follows the technological development of advanced countries in the world, and through its own efforts, has developed a new HDR-01 digital crawler imaging detection system.

The system can visually present the inspection results of pipeline welds in the computer in real time, and is helpful for operators to judge the inspection results on site. At the same time, the on-site test results can be retrieved remotely, saved for record, or the results can be directly verified by experts. The system can directly print the position and location information of the site, the time, the welding port number of the work site, and some related information on the image without modification, completely avoiding the suspect of cheating.

The system is composed of the following parts: remote PC, DR imaging board trolley, external radiographing machine trolley, internal shooting pipeline crawler and other systems. Through the wireless local area network, the control and acquisition (transmission) of the map can be completed at one time. The staff can remotely control the computer to complete the inspection of the pipeline weld and save the original image for retrieval and flat film. The image of the system is clear, and the double-wire evaluation fully meets and exceeds the requirements of national standards.

2. Composition of equipment

The system is composed of two parts: in-pipe shooting equipment and outside shooting equipment.

Internal shooting equipment composition:

High-frequency X-ray pipeline crawler, pipeline outer wall crawler (carrying flat panel detector, central router, lower computer PLC), DR flat panel detector, PC workstation (digital image acquisition and processing software).
