Pipeotech clocks up cryogenic milestone for DeltaV-Seal™ Norway’s Pipeotech extends its industry-first 10-year gas-tight warranty for its ground-breaking DeltaV-Seal™ gasket all the way down to applications running at -196°C, based on stellar results of cryogenic leakage tests at a pre-eminent European research lab. Pipeotech launched its metal-to-metal DeltaV-Seal in 2015. Backed by unique DNV GL type certification, DeltaV-Seal immediately set a new gas-tight standard for industrial gaskets, offering the first sealing solution that was proven to stay exceptionally tight over time with zero maintenance or retorquing required. After proving it efficacy in sectors ranging from hydrocarbons to chemicals processing, maritime, pharmaceuticals and food and beverage production, in 2020 Pipeotech launched the sealing industry’s first 10-year gas-tight limited warranty, creating a truly unique value proposition and cementing the claim of being the tightest, safest and most durable flange gasket technology in the world.
