Over-lapping Insulation Protection (OIP)

Non-Seamless Metallic Cladding contributing to Corrosion Under Insulation (CUI) is a serious problem worldwide on Hot Thermal and Cryogenic insulation applications. It is calculated that $2,000,000,000 USD per year is lost in pipeline replacement, repairs, and production down times due to CUI.

Typically, destruction and corrosion of insulated pipelines using metallic cladding in hostile environments which results in CUI and significant extra cost to the installation due to water ingress into the insulation system as metallic cladding is non seamless and is prone to mechanical damage

Not only is the health and safety and environmental impact of the products important, but the application must also be able to withstand the harsh rigors of the Marine environment, the temperature variations, and the UV extremes Trinity has developed UV curing Non-Metallic Cladding and Twin curing composites. This has provided unique engineering opportunities for application solutions in the Oil & Gas, Water, Chemical and Marine industries. The photo below illustrates a hybrid Polymer resin, which was post applied after installation of the OIP laminate. This was important in a particularly harsh marine location subject to seasonal high velocity wind-blown C5 environment which could cause moisture or water ingress into metallic cladding.

The Main Use

UV Curing Materials Are Applicated in Pipe Support Protection.

Technical Principle

Because of the daily operation and delivery of liquid products, the supporting of the service pipe is easy to be damaged caused by corrosion or friction when the pipe expands and contracts, which threatens the safety of pipe operation. The new products of Trinity’s are wear-resistant, high-strength UV curing materials, which can be used both in the pipe and the support parts. As the materials of the two places are both wear-resistant materials, the intersection site is not be damaged due to friction. The pipe itself gets the material reinforcement protection, and its strength has been greatly improved, which avoids water corrosion problems caused by rain.

Technical Character

• Simple and convenient in construction, high strength, long service life.
• UV-curing film materials circling the pipe to protect and reinforce corrosion-resistant of pipe, which has good effect to the pipe protection.
• No destructive friction between composite slippage and pipe patch or pipe circling protection.
• Saddle-type pipeline patch, flexible to combinate and use.
