Process

From Requirement To Completed Job

Assessment

Decide what area you are treating and what access you have. Open flat deck, corners and welds, and vertical structure each need a different tool.

Tool selection

Deck scalers for open area, needle scalers for corners and welds, descaling chain machines for pipework and structure. Pneumatic where service air is run, electric where a suitable supply exists.

Supply setup

Confirm the air coupling standard or the voltage and frequency before the tool is ordered. This is where most delivered tools fail to go into service.

Preparation

Blow down and vacuum loosened scale and dust. A pneumatic vacuum cleaner keeps scale out of accommodation and machinery spaces.

Detail work

Wire wheel, cup and end brushes finish the areas the machines cannot reach.

Protection

Crew on a long descaling campaign need anti-vibration gloves, goggles, helmets and harnesses issued at the same time as the tools.

Reorder

Needles, chains and brushes are consumables. Order them with the machine and again before the next campaign.

Answers

Hull And Deck Descaling Questions

Which tool covers the most area per hour
A deck scaler on open flat steel. It is the wrong tool for corners, welds and around structure, which is where the needle scaler earns its place.
Do I need pneumatic or electric
If service air is already run to the working area, pneumatic avoids trailing cable and suits spaces where an electrical tool is not appropriate. Where a suitable supply exists, electric is simpler to set up. Both versions are listed under separate codes.
What stops the scale getting everywhere
A pneumatic vacuum cleaner used as part of the sequence, and blowing down with an air duster nozzle before coating.
How do I stop the campaign stalling
Order needles, chains and brushes at the same time as the machine. Consumables are the usual reason a descaling job stops halfway.
