ProTek® Fire and Blast protection Flange Covers
ProTek® flange covers are designed and engineered to protect ANSI flanges and compact flanges from failure due to the effects of blast followed by hydrocarbon jet fire. The protection cover also ensures that the flange bolts are fully protected throughout the duration of the jet fire.
The covers can be provided to meet a range of different blast and jet fire scenarios and to fit to the full range of standard flange sizes.
The flange covers are manufactured using lightweight ProTek® composite technology that has been used on several hundred equipment enclosures currently installed on onshore plants and offshore installations in UK, Norway and the rest of the world.
The ProTek®flange covers are designed for use in harsh environments encountered offshore with no degradation in performance offering a low lifecycle cost for 30 year design life.
Technical integrity, zero maintenance and low life cost ProTek®flange covers provide inherent thermal insulation, fire protection and noise reduction characteristics in accordance with NORSOK R-004 Classes 5, 6, 7 and 8.
Certification of the product is carried out by Det Norske Veritas (DNV) or Lloyd’s Register and is based upon full scale blast testing up to 1.5 barg overpressure and jet fire testing carried out for more than 2 hours.
