400-1100 Mm X - Ray Pipeline Crawlers 250Kv 17Ah Ndtpipeline Crawler Ndt X Ray Equipment
The X-ray pipeline crawlers include the special part that can detect the welding line of long pipeline. The X-ray pipeline crawlers have the advantages of high radiographic quality, high imaging sensitivity, low failure rate and high work efficiency. The X-ray pipeline crawlers have differential driving and vibration absorbers. The chassis of the X-ray pipeline crawlers can be moved in the pipeline steadily without off center running and overturning. The X-ray pipeline crawlers can be moved in the pipeline with great efficiency because it is controlled by PLC with protecting it from blocking and under voltage. The X-ray pipeline crawler is easy to be separated into several parts and then to be put together, so it is easy to carry. You can change the exposure parameter and make the X-ray pipeline crawler move, stop and have an exposure with the exterior controlling source. The X-ray pipeline crawlers are easy to operate.
1 Overview
The X-ray Pipeline Crawler is a kind of central radiographic equipments for detecting pipeline welds in long-distance pipeline constructions. The X-ray pipe crawler can be guided into pipes by magnetic locator, and the center of the radiation field can be illuminated at the center of the weld bead. The whole welding joint can be detected in one exposure. Compared with directional radiators, X-ray pipeline crawlers have higher work efficiency but require lower labor intensity. X-ray pipeline crawlers are mainly used in petroleum pipelines, natural gas pipelines, thermal pipelines, etc.
2 Main charateristics
2.1 Unlike controlling the equipments via listening to sounds, manipulators can control the exposure moments and manipulate the X-ray pipeline crawlers to move forward or backward via magnetic orientator.
2.2 Magnetic locators have the following features: higher positional accuracy, strong penetrability, and higher stability. The magnetic transmitter is equipped with electric display.
2.3 The X-ray pipeline crawlers can display the voltage of the battery and directly judge the use of the battery.
2.4 The X-ray pipeline crawlers’ software is written with fault codes. Please refer to the fault code table to detect equipment malfunctions.
2.5 The X-ray pipeline crawler has smaller size, lighter weight, and it is more convenient for transportation and operation.
2.6 Equipped with all kinds of protection functions, including encountering water protection, 20 minutes no one operation protection, etc.
2.7 Users can replace the controller, the circuit board, and other parts easily due to modular design.
2.8 The generator adopts a small 2005 portable circumferential cone target flaw detector: the controller and the head of the machine are separated, which is more convenient for users to replace, debug, and test. If the generator is equipped with the controller, the whole set can be used as a portable flaw detector.
2.9 The crawler is equipped with false load, and the time is set for 0.2 minute. The crawler can simulate the real load working, such as exposure, moving forward or backward without connecting pipe head. This function enable users to learn how to locate and determine the fault.
2.10 The lengthening shaft adopts keyless connection, which is more convenient to replace.
2.11 The magnetic receiver has 8 gear ranges, which satisfy the requirements of different diameters.
