A-0500 - Grinding disc for paint - Safety Tools Allmet

Introduction to the grinding disc for paint

A-0500 – Grinding disc for paint is the only Ex-certified grinding disc. The grinding disc is made up of 95% wolfram carbide. The hardness reaches 9,7 on the Rockwell scale. The disc is certified safe to use in ATEX↵ gas zone 1 and 2 and ATEX dust zone 21 and 22. Stop the need for time-consuming risk analysis and cost bound to shutdowns, fireguards, Hot Work permits↵, habitats, and demanding clean-up work.

Tech details:

Diameter – 80mm
Use with – A-0105
Weight – 410g

Micrometer result

Average of 72 µm surface using this grinding disc.

The result after grinding follows the SSPC SP-11 surface treatment standard.

Ex-certified grinding without «hot work permit»

A-0500 – Grinding disc for paint can repair 32 000 corrosion spots of 5*5cm.

The tools are used almost daily and there is minimal wear on the teeth. I see benefits in getting work done without much delays as I do not require hot work permits. All I require now is a blanket permit for the air compressors and my team can work on the individual lines. There are significant cost savings as we get much faster turnaround

I believe the introduction of EX-Certified tools that are classified as Cold Work by DNV is a major step forward - for safety, the environment, and the health of all personnel using this class of tools

Arvid Skines / Main Safety Delegate, for the StatFjord Field

In my 20 years' experience, I have never before seen a new tool that has shown such promise, radically improving the HSE situation at offshore facilities. Personally I think it should be mandatory.

This technology will also be very important for safety in onshore O&G plays, refineries and just about anywhere else with EX potensial. It offers a possibility of doing these jobs with no shutdown or slowdown in production and increased safety for workers and infrastructure.

Health, Safety, and the Environment

Our grinding products are designed to comply with Health Safety & the Environment (HSE & OSHA) requirements. Offering low vibration, low heat, and low noise levels. The fragments produced are large and blunt and will stay within a few centimetres/inches of your work area. This makes cleaning up simple and safe.

Long-lasting

Safety Tools Allmet rotating grinding burrs and discs have a long lifespan and consist of solid tungsten carbide, which gives our burrs and discs a material property harder than an industrial diamond. The lifespan of the rotating grinding burrs and discs depends on the application, but generally, they last hundreds of times longer than conventional alternatives.

By using Safety Tools Allmet's Steel Grinding Suitcase we completed the job in half the time conventional methods would have taken. In the process this saved circa £ 300 000 in costs.

John Henderson / Archer, Project Manager

The work went really well with very low noise and very little vibration. We are all in all very satisfied with the tools - we saved about a week's worth of work.

Bjørn Erik Dahl / Aker Offshore partner, Material coordinator

The Safety Tools Allmet grinding tools were tested under anticipated worst case conditions - operation within explosive mixtures of propane and acetylene. It was not found possible to provoke ignition of the explosive mixtures during any of the tests performed.

Tungsten Carbide

Our rotating files and discs consist of solid tungsten carbide. The hardness and design of the teeth significantly increase the lifetime of the grinding files and discs. You can expect a lifetime of 100 times more than conventional burrs.

Spot Repair

Ex-certified cold work tools from Safety Tools Allmet provide a good, clean surface with a profile that meets the requirements of the SSPC-SP11 Surface Preparation Standard.

Surface profile

The solid tungsten head for Safety Tools cold rotating grinding files has different designs on its teeth so that they can produce different surface profiles for every situation. Our burrs create a roughness profile of between 40 – 75 microns.

Adhesion and Cleanliness

The correct surface profile creates a suitable anchor for paint and coatings. ATEX grinding tools from Safety Tools Allmet create good adhesion and a clean surface. Extensively independently tested for surface adhesion by International Paint, Jotun, Chevron and Weatherford.
