General
|
WPU Series is multi-channel B-scan ultrasonic inspection system. This
system is intended for high speed ultrasonic inspection of spiral or
longitudinal welded pipes. It is installed for on-line or off-line
inspections.
|
|
Inspection Range
|
Inspection range includes 100 percent of weld volume per ASTM E 1961.
The weld is divided into zones, each from 1mm to 3mm deep. Pipe-body
inspection range from 20 to 100 percent volumetric coverage per inspection
specification
|
|
Inspection Standard
|
Flaw detection meets or exceeds API Spc. 5L and 5CT, or as otherwise
specified by the customer
|
|
Multi-channel
|
The basic system includes 16 channels with expansion capacity to 32
channels for enhanced flaw detection in heavy thickness welds. For
pipe-body inspection, depending on inspection coverage and
inspection specification, it reaches 16 to 48 channels.
|
|
Inspection Mechanics and Tracking
|
Gantry and column scan system with vertical axial and rotational
adjustment for pipe diameter and weld pitch. Tracking mechanics use
contact or non-contact motorized method
|
|
Inspection Speed
|
B-scan linear inspection speed along with weld line is 150mm/sec and
A-scan is 500mm/sec
|
|
Flaw Marking
|
Automatic marking of indication exceeding rejection threshold with
waterproof paint
|
|
Inspection Report
|
Inspection report and list of defect is based on customer
requirements. It includes detecting channel, gate, threshold
level, position, B-scan, and TOFD display
