EIWAA Marine Services offers Weld Testing and welding inspection services by Non-destructive Testing Services by Rope Access Services or Normal Access Services in Saudi Arabia. All the weld surface NDT Inspection Services of Eddy Current Inspection Services and Magnetic Particle Testing shall be performed along with DPI Testing as supportive Services by EIWAA Marine Services. NDT Testing and Third Party NDT Services of Eddy Current Testing Inspection  by Rope Access Services is different from other marine services  in Saudi Arabia Ports and offshore industry.

Penetrant Testing (PT), also known as dye penetrant testing, is based on the capillary action that causes a liquid to rise when confined to a small opening and the surface wetting property. Our NDT Technicians are approved by ABS and BV to execute Penetrant Inspection on welding surface with a wide range of shapes, sizes, and materials, including

  • Metals
  • Composites
  • Glass
  • Ceramics
  • Rubber
  • Plastics

As a standard technique, the temperature of the penetrant and the surface of the part to be processed shall not be below40º degree F (5ºC) and not above 125º degree F (52ºC) throughout the examination period. Local heating and cooling are permitted provided the part temperature remains in the range of 40º degree F (5ºC) nor above 125º degree F (52ºC).Penetrant may be applied by dipping, brushing, or spraying. Filters shall be used on the upstream side of the air inlet when using compressed air to apply penetrant.The length of time the penetrant must remain on the part to allow proper penetration shall be as recommended by the penetrant manufacturer.

Procedure for Solvent-Removable Fluorescent Penetrant Examination

Temperature Limit 40° to 125°F (5°C to 52°C)
Surface  Conditioning Prior to Penetrant Inspection As   welded,   cast,   rolled,   forged   condition   unless   otherwise instructed.
Pre clean Approved solvent cleaner.  Allow to dry minimum 5 minutes prior to proceeding with the test.

Penetrant Materials

(Attachment V)

Solvent Removable Fluorescent

Dry Developer

Aqueous Developer

Non-Aqueous Developer

Penetrant Application Depending on whether penetrant is supplied in bulk containers or aerosol cans, application can be by dipping, brushing, flooding, or spraying.
Penetrant Dwell Time 10 to 20 minutes depending on defect sought per Table 1.

Excess            Penetrant


Remove penetrant with a dry, clean, lint free cloth or paper towel, followed by moistened clean, lint free, white cloth or paper towel.

For final removal of excess penetrant use a dry, lint free white cloth or paper towel.

Developer Application

Spray at 250mm to 300mm (10″ to 12″) from the surface.   If

Aqueous (water based) developer is used, flood the surface and allow to dry.

Inspection Lighting

Black Light – 1000 µW/cm² – 3000 µ W/cm²

White Light – Maximum = 2 ftc

Post Cleaning Wipe surface clean with dry cloth.  Flush surface with an approved solvent cleaner.    Wipe  as  required  with  a  clean  cloth  and/or absorbent paper towel.
