Glass Reinforced Plastic (GRP)

Glass Reinforced Plastic (GRP)

The development of corrosion under insulation (CUI) on pipelines is particular dangerous due to the simple fact that it’s not visible and can’t be detected/monitored by visual inspections. Corrosion that is allowed to develop over years, may eventually lead to cracks or defects in the pipe or process equipment, resulting in release of hydrocarbons and the risk of catastrophic fires. The process of corrosion development on pipelines and other process equipment is dependent on many factors. It’s therefore of outmost importance to understand how different insulation materials interact together and effect the contributing factors for CUI.

Glass Reinforced Plastic is a composite material consisting of glass fibers embedded in resin which has been manufactured to be used as a non-metallic cladding to protect insulation materials against corrosion, water vapour and humidity permeance. It has been used in Oil, Gas & Petrochemical industry. Corrosion Under Insulation (CUI) is a major problem to the Oil & Gas Industry. The risk of loss of integrity of pipelines and equipment is well understood in terms of both safety and financial cost therefor UV cured GRP has find its use in Oil and Gas Industry to protect pipes and pipe insulations. Embedded glass fibers give the GRP excellent properties like durability, flexibility, stiffness and resistance to chemical harm.

Packaging & Storage:

The material will have shelf life of 18 months when stored below 25°C in a cool dry place. Final product must be correctly kept and packaged in its unopened opaque black plastic wrapping in horizontal position. All the boxes should be rotated every 30 days by 180°. Protect material from sunlight or UV light at all times prior to installation.


Transfer to Worksite:

All material transferred to the worksite shall be stored undercover and kept away from sunlight/UV light until required and kept in its opaque wrapping. In areas of strong solar radiation where the might be a risk of premature curing shielding can be erected to eliminate direct sunlight.
