Project Details
W.G. Beaumont & Son Ltd of Romford are a National Gas Grids chosen contractor for applying surface coating protection to pipe weld joints and fittings in refurbishment programmes carried out in various areas of the UK. A typical contract for National Grid carried out by W.G. Beaumont using Denso Protal 7300™ liquid coating is shown on this page. Once the pipe support was removed the pipe was blasted to Sa 2 1⁄2 and two coats of Denso Protal 7300 were applied.
The support itself was blasted, painted and neoprene rubber fitted before replacing it to its original position. On the pipe risers W.G. Beaumont removed the existing coating, blasted to Sa 2 1⁄2 and applied two coats of Protal 7300 to a minimum of 500mm above and below ground. These areas were then ready to be over-coated as per National Grid’s specification.
W.G. Beaumont now uses Protal 7300 on all their projects. Denso Protal 7300 has been specially developed to enable application to wet, damp or dry surfaces which is a great asset in the United Kingdom’s unpredictable climate.
