Detection process
◆ Weld longitudinal and transverse defect detection, tandem detection of weld blunt edge area and delamination detection of weld heat affect zone
◆ Blind zone of pipe end: longitudinal and delamination detection≤50mm; transverse detection ≤ 50+2×T (T is wall thickness)
◆ Detection Method: spiral weld: water film method
Longitudinal welded pipe: water film method or water jet method
ERW/HFW welded pipe: water jet method
Detection standard
◆ API SPEC 5L 《Steel pipe specification of pipe line》(45 Edition)
◆ DEP31.40.20.37 （2011）《Pipe specification of shell pipe line》
◆ ASME A578/A578M-96 ASTM A53 ASTM A500 JIS G3444 GB/T 3091
◆ Q/SY GJX 101-2010《General technical requirements for steel pipes for natural gas transmission pipelines of the China Petroleum Pipeline Construction Project Department》
The form of mechanic structure
◆ Gantry beam type (traditional type)
◆ Truss structure form
◆ Lateral beam form
◆ It can also be customized according to the specific requirements of the user on site
System software
1. Perform a 1:1 simulation of the weld, visually showing the position of the defect in the weld
2.The coverage area of probe can be set through simulation software, reducing the time for manual probe adjustment
3.C,D scan can visually show the axial and circumferential position of the defect
4.In the process of automatic detection, the system will automatically generate an audible and visual alarm when it detects defects or delamination and poor coupling in thickness measurement.
Technical advantages
Multi-angles
Fully phased array technology ultrasonic testing of weld, full sound beam coverage of weld from multi-angle, can greatly improve the detection rate of natural defects, and ensure no omissive detection to the greatest extent
Visualization
Phased array imaging detection can have B-scan, D-scan, S-scan and C-scan at the same time. Through modeling, three-dimensional graphics can be established, defect display is graphical, and the effect is intuitive.
More effective
The phased array can perform sound beam focusing, and the sensitivity and resolution are greatly improved; equipped with a new generation of intelligent laser tracking system, the detection results are more reliable.
Easy to operate
With electronic angle deflection, one phased array probe replaces multiple conventional A-ultra probes, fully meeting API and Shell standards, reducing requirements of mechanical design, reducing debugging time, and improving production efficiency.
