Coatings Removal & Surface Preparation Briefing Guide
Briefing Guide: Coatings Removal & Surface Preparation
Things to consider when deciding to choose water jetting for Surface Preparation and Coatings Removal .
- A good supply of potable water is required (Ideally a fire hydrant – for applications using water pressure up to 1000 bar we are able to use process grade water) 1.5 – 3.0 cubic meters per hour.
- A suitable area for laydown of plant (Van and trailer combination or truck options are typically 10m in length)
- A work platform/scaffold must be available for hand held lance work – Typically seven boards wide in 2 meter lifts.
- Coatings removal from steel storage tanks may be undertaken while tank remains on line.
- Limpet Crawler System requires an over- head safety restraint mounting point to protect in case of vacuum failure.
- Hand held water jetting lances produce noise – Consider the use of acoustic blankets around each work enclosure to bring noise down to acceptable level
- Waste water containment, filtration: RGL have our own system for handling this element of the work for you.
- Waste water disposal: Normally after filtration to remove majority of solids, the water is pumped to site drainage or effluent plant. If no effluent plant is available on site then a licenced liquid waste tanker service provider/ disposer will be engaged.
- Productivity: Generally several times quicker than using conventional techniques. Sometimes water jets offer the only effective method of removing tenacious coatings or deposits.
- Removed solids are normally collected in drums or skips ready for disposal.
- Our Plant is diesel driven and as such requires a well-ventilated area in which to operate.
- Our diesel engine pump units are fitted with spark arrestor and chalwyn valve
- Our Plant should ideally be positioned adjacent to the work face. It may however be operated remotely over 100m from the work face under special circumstances.
