Excerpt from: Case Study – Use of Safety Tools Allmet Abrasives
Experiences from work performed using Safety Tools Allmet
Simplified rigging, only compressed air hoses for connecting the tool. We did the job in less time than expected due to a higher capacity than standard tools for mechanical pretreatment. (Flap-disc, needle gun, and other standard options) abrasives equipment or grinding tools was not replaced, very little wear.
Because of faster production method provides cost savings. The files are made of special steel and last a long time. The machines are very robust (tough) and long-lasting. When we finished this job, the grinding tool was still usable, and you can still use the tool on multiple jobs.
Low RPM and the teeth design of the abrasive tool provide minor breakage during either corrosion or paint grinding. This provides little dust problems. The tools have low vibration levels and give slight vibrations to the operator. Old paint is not warmed up to release dangerous fumes when pretreated. The grinding tool is certified as cold work and presents no danger of explosion when working in potential explosion areas.
Statement by the operator after testing equipment:
- The equipment works well. It does not create dust issues, and therefore respirator is not needed.
- The equipment produce low noise.
- The tool works quickly and requires little force to remove paint and rust.
- The equipment is reliable and has no operational problems.
- We removed a thick coating effectively and worked faster with this tool.
The tool provides cleanliness and roughness following the requirements per NORSOK M 501. Clean: St 3 / Sa 2 ½ ref ISO 8501-1.
Medium-ref ISO 8503. The tool works efficiently and provides an excellent surface for the subsequent paint system. Tool design gives good rounding of edges to existing intact coating. The paint system achieves good surface adhesion because of the excellent roughness profile.
Pipe repair at offshore-platform
A leak occurred in a pipeline at a sizeable offshore location in the North Sea, within the Benelux. This leak (in an ATEX↵ zone)
It was decided to use the rotating file A-0004 Little Papa for the proper surface preparation. The decision was made because the A-0004 has an average surface profile of 83 μm. This is precisely what was required for the repair products.
This repair is a completely cold solution and avoids welding and hot surface preparation. The leak-sealing team works with the EX-certified Safety Tools Allmet.
For this leak repair, there was no need for any hot work permits, no-risk evaluations, no job delay, no need for habitats, no need for fireguards, no hot sparks, and no emission of isocyanates.
