PIPE & TUBULAR
an identical instrumentation system including pressure reduction sample conditioning equipment, a Danalyzer gas chromatograph, Rosemount pressure transmitters, calibration facilities and various safety devices and accessories. The two cabinets house cylinders to supply the required gas for calibration purposes, along with associated pressure regulation, measurement instruments, tubing connection and flow control components.
The GRP material used by Intertec to build the shelters and cabinets is a proprietary multi-layer composite with moulded GRP panels enclosing polyurethane foam insulation,
protected by gel-coated surfaces.
This composite material has a very high thermal resistance, reducing the amount of energy required to heat equipment. A further benefit of Intertec’s approach to shelter fabrication is an advanced gel-coat, which is applied in a much thicker layer than alternatives such as paint. It protects against ultraviolet (UV), and is highly effective against abrasion. It offers exceptional environmental protection and resistance to ‘corrosion’ (GRP does not rust or degrade in any meaningful way), allowing maintenance- free lifecycles of 30-40 years – more than enough to meet the anticipated cease of production date for the platform.
The gel-coat also incorporates a unique nanotechnology treatment that provides conductivity to dissipate static electric charges safely to ground – protecting against sparking in hazardous areas. Developed for Intertec by BÜFA, the coating employs single-wall carbon nanotubes (SWCNTs) to provide conductivity. Because the SWCNTs are only around 1-2 nanometres in diameter, they enhance surface smoothness. The gloss retention after accelerated weathering tests of this surface is some 50% better than the previous coating technologies used. This technology is behind the significant improvement in resistance to UV of Intertec's shelters. Previously, exposure to high UV levels over the long term could lead to surface roughening – which is sometimes referred to as ‘chalking’ or ‘frosting’. Intertec’s weathering tests have demonstrated that the new coating will withstand extended exposure to very high UV levels – providing hitherto unachievable protection for GRP field enclosures destined for ultra-harsh environments such as offshore platforms, deserts and Arctic environments.
