The detector system can be used as applications below:
- When an undetected defect in raw material or finished component can become a dangerous fracture.
- Checking for potential fatigue cracks or flaws during maintenance where parts of vehicles, cranes and other equipment are subjected to heavy stress.
- Inspection of welded areas that must be free of flaws e.g. industrial heating equipment oil tanks fabricated from mild steel.
- Machined surfaces or parts of equipment used for pressing operations.
- Aluminium die-castings can be examined for minute flaws or cracks.
Application Instruction
The Spanjaard Flaw & Crack Detector System is available as a three pack aerosol. The Three Pack System should be used as follows:
1) Cleaner
Remove all surface contamination such as oil, grease and dust. Spray surface with cleaner (Pack 1) and clean thoroughly with absorbent cloth until no further contamination is evident on the cloth/tissue.
2) Penetrant
Parts must be at ambient temperature before spraying. Liberally spray the area with Penetrant (Pack 2) and allow 5 minutes contact time. Allow up to 20 minutes for very fine cracks.
3) Cleaner
Spray Cleaner (Pack 1) onto an absorbent lint-free cloth and wipe off excess from surface until no further Penetrant (Pack 2) is evident on the cloth. This step is vital to ensure cracks and flaws are detected.
4) Developer
Shake container before use. Spray on a thin, even film of Developer (Pack 3) and leave on for at least 10 minutes before inspecting for the fine flaws.
