Application Examples

Insulating load bearing pipe supports

Durolight^®, a fibre reinforced insulating composite was designed and developed to meet the thermal and mechanical requirements of load bearing supports in LNG applications. The very low thermal conductivity and ability of this material to operate in environments with temperatures from 196 °C to +200 °C (-320 °F to 392 °F) make it an excellent choice for insulation of pipelines and also for use as thermal breaks within the Oil & Gas industry. Durolight^® is naturally flame retardant & halogen free, resistant to weathering, abrasion and wear. With these exceptional properties having led to Durolight^® being approved by such companies as Bechtel Corp, Linde AG and Tractebel S.A./N.V.
