A pinhole detector is the ndt instruments used to detect pin hole,seal leak,cracks or flaw on the coatings.

PD-001 Pinhole Detector:

Pinhole detector

PD-001 Pinhole Detector is applied in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for corrosion protection over metal and concrete (conductive) surfaces.
With corrosion an extremely costly and disruptive worldwide problem, preventative determination becomes essential.
For newly constructed tanks, pipelines and other installations, where corrosion prevention coatings have had to be applies, specifications will normally call for a specific coating to a specific thickness. By using our Detector to verify the competency of the sealing coatings, the contractor can be assures that his coatings responsibility has been met.

Complies with Standards: ISO 2746, BS 1344-11, ASTM G 6, ASTM G 62, ASTM D4787, ASTM D5162, NACE RP 04901, NACE RP 0274, NACE RP 0188, JIS G3491, JIS G3492, AS 3894.1, EN14430 and ANSI/AWWA C 213 etc.

Pinhole detect machine:

Pinhole detect machine

Functions

Detect the pinhole on the leveled straight plate with high speed.

Detecting method:

Ultraviolet tube

Diameter of detectable pinhole

10 μm

Ultraviolet sensor

Photoelectric Amplifier

The minimum time interval of contiguous pinholes

5 ms versus pinhole of 25 μm

Maximum speed

1830 m/min

Marginal light shield

 6.3mm is a must:while the move ment range side of the plate or the width variation is within 1mm,the marginal light shield can be 3mm

Maximum speed

  60mm/second

Self calibration

The maximum time interval is one week under general conditions; and more frequent self calibration must be conducted under worse conditions to ensure the normal operation of the system.
