Introducing the new PSP-4 automated ultrasonic inspection system. This is the most advance and newest generation of P-scan system with eight (08) channels. It is designed to be easy and fast to set-up with high flexibility for different scanning situations.
This system supports a variety of ultrasonic inspection techniques inline with today’s demand for quality, pre-service or in-service inspections:
Our long list of clients includes:
- Projection scans (weld inspection)
- Corrosion mapping (parent metal inspection)
- TOFD (quick detection and accurate sizing)
- Through transmission
- A-scan (recorded for post-processing)
Projection scan is a projection of comprehensive B-scan data, which gives the side view of the inspected component.
It is used for weld inspection with specialised probes, where the scan results is shown in projection of top, side and end view, thus provides a threedimensional visualisation of the defect or corrosion. Different colour codes are used to indicate the origin of each signal, together with its amplitude to facilitate analysis of the scans.
Corrosion mapping is used on parent materials of vessels, pipes, storage tanks and other structures. This is especially useful for corrosion monitoring of large structures or key areas for any pitting, general corrosion or severe corrosion.
Each scan is represented by pixels of colour scale that corresponds to its thickness measured. It can be view in top, side and end view to give a visualisation of the component’s condition. A-scans can also be recorded and exported to other user friendly programs such Microsoft Office to plot a three-dimensional view of the scanned area.
Time of Flight Diffraction (TOFD)
Unlike conventional ultrasonic which relies on reflection based techniques, TOFD is based upon diffraction and reflection of ultrasound.
This increases the probability of detection since it is less affected by the angle of incident with respect to the orientation of the discontinuity. Discontinuities orientated perpendicular to the surface is also detectable as well as discontinuities in the weld fusion faces.
Why Our Automated Ultrasonic System?
- More than one inspection type or configuration can be included in a single setup and data from all the inspection
can be collected concurrently. Up to 8 probes are possible at one particular job.
- Our scanner is a steerable general purpose magnetic wheel XY scanner, ideal for high speed, long Y-stroke
inspection with several probes attached simultaneously.
- Coupled with rope access method, it enables this system to carry out inspection to cover large and hard to
reach areas such as large vessels, storage tanks and spheres, and is much more cost effective than expensive
- Qualified Ultrasonic personnel, trained by Force Technology to operate this PSP-4 system.
- Conforms to standards for ultrasonic inspection and CE markings for equipment.
- We have wide range of specialised probes to suit different conditions to obtain the best results.
- All inspection data including A-scans can be recorded and stored in a computer for post-processing. This also
provides a permanent record of the job that enables documentation and traceability for future inspections.
- The receiver has selectable frequency filters and uses logarithmic amplifier that goes up to 120dB, to achieve
better penetration on to course grain material such as duplex stainless steel, etc.
Operates in a pitch and catch configuration, ultrasound is transmitted on the component and received by a second probe on the opposite side. Variation in received signal amplitude indicates a presence of discontinuity.
