SST Series Automatic Ultrasonic Inspection System for Seamless Steel Pip




Structured tube, gas vessel tube, nuclear power tube, Line pipe and fluid tube, high-pressure boiler tube, oil drill pipe and other seamless steel pipe

Inspection Technology

1) Seamless steel pipe in the Longitudinal, transverse, layered defects and wall thickness measurement

2) Blind tube end:Longitudinal and layered detection ≤ 50mm

Transverse detection: ≤50+2×T(T is thick pipe)

3) Detection method:

– Water membrane coupling type(For large diameter thick-walled tube, simple adjustment)

– water jet membrane coupling type(For small diameter thin-walled pipe, a small field near blind)

– Partial immersion type(Suitable for larger weight, the surface roughness of the workpiece)

– Dry coupling type(the electromagnetic ultrasonic method)
4) Eddy current testing system can be integrated, To realize ultrasonic and eddy current Joint automatic detection
Test Standard

– GB/T5777-2008《Seamless steel pipe ultrasonic testing method》

– YB/T4082-2000《ipe automatic ultrasonic flaw detection system performance test method》

– GB/T7735-2004《Steel pipe eddy current testing method》

– API 5LAmerican Petroleum Institute Standard《Specification for Line Pipe》
– ASTM 213M《Metal pipe ultrasonic testing method》

– ASTM A106 ASTM Standards《Seamless carbon steel pipe for high temperature》

– ASTM A519 ASTM Standards《Mechanical engineering with carbon steel and alloy steel seamless steel tube》
Technological Advantage

1) Instrument parameters: Can meet eu standards(EN12668-1), and the standard factory inspection, while providing European standard certificate.

2) Inspection Speed( repeat frequency): The line speed of up to 60 m/min, Repetition frequency up to 5 KHZ(And the detection rate is closely related to the technical specifications for the repetition frequency)

3) Channel independency: Strict independence between channels, each channel has its own existence independent transmit and receive timing control

4) Instrument scalability: To meet the higher testing standards or the actual needs of users, the number of channels can be expanded.

5) Modular design: convenient service

6) Machine design, processing, installation and debugging:large mechanical design team,Trusted cooperative processing units, assembly debugging standard management, accumulated a wealth of experience in similar projects, supporting the well-known brands purchased parts.

7) Control segment: using well-known brand components and customer production lines matching OP operator terminal display operating status and fault information standard design
8) C-scan thickness of image display, Thickness measurements show grade in at least 64 kinds or more, at the same time obtain circumferential and axial thickness distribution
The mechanical structure form


Fixed gantry type(Suitable for thick-walled and large-sized steel tube)
2) Moving bogie(Suitable for off-line testing)
3) Cantilever beam type  (Suitable for online testing)
4)Can also be customized according to the specific requirements of the user site
