Ultrasonic automatic testing equipment for bi-metal composite pipe
Bi-metal composite pipe, metal and non-metal composite pipe, etc.
◆ Longitudinal, transverse, oblique, delamination defects and wall thickness measurement in the base pipe
◆ Longitudinal, transverse and delamination defects in the lining pipe
◆ Blind zone of pipe end: longitudinal, oblique and delamination detection ≤ 50mm
Transverse detection ≤ 50+2×T（T is wall thickness）
◆ Detection method: 1. Water film coupling type (applicable to large diameter thick-walled pipes, easy to adjust)
2. Water column coupling type (applicable to small diameter and thin-walled pipes, with small near-field blind zone)

System software (Function description and interface display)
1.The original image shows the position of the defect in the axial and circumferential directions through C-scan
2. Through the interaction with the electronic control program to ensure the accuracy of marking in the circumferential direction, realize the software automatic control of the electronic control program, and reduce the artificial operation fatigue
3. Realize the data storage of outer pipe and inner pipe at one time for convenient analysis
4. Reduce the blind zone of the transverse probe at the end of the pipe through B scan and C scan.
5.The system has a pre-alarm function. The pre-alarm line can be set at will, but it must be lower than the alarm line.
The form of mechanical structure:
◆ Gantry beam type (traditional type)
◆ Water tank liquid immersion form
◆ It can also be customized according to the specific requirements of the user on site
Technical key points
◆ Instrument parameters: meet the European standard (EN12668-1), and the factory inspection is according to this standard, the European standard inspection certificate can be provided at the same time;
◆ Detection speed (ie repetition frequency): the detection linear speed is up to 60m/min (the technical index closely related to the detection speed is the repetition frequency, the current repetition frequency of Zhongke can reach 5KHZ);
◆ Channel independence: The channels are strictly independent, each channel has its own independent emission and reception timing control;
◆ Instrument scalability: The number of channels can be expanded according to the actual needs of the user, such as when detection or meeting higher detection standards when additional channels are needed;
◆ The instrument adopts modular design, maintenance is convenient and quick;
◆ The internal and external detection works at the same time, which can effectively detect the base pipe and the lining pipe;
◆ Image display of C-scan thickness measurement, the thickness measurement display can be at least 64 or more gradations, and the circumferential and axial thickness distribution can be obtained at the same time, and the thickness measurement accuracy is 0.1mm;
◆ Mechanical design, processing, installation and debugging: experienced mechanical design team, trustworthy collaborative processing unit, standardized management of assembly and debugging, accumulated rich experience in similar projects, well-known brand of matching outsourcing parts;
◆ Control part: using domestic and foreign well-known brand components, the control program is in accordance with the beat of customer's production line, fully protecting the safety of personnel and equipment, and the operation is humanized. The OP operation terminal displays the operation status and fault information.
