Saving cost, adding value - from day one

Your pipes can deliver competitive advantage. In industries where ‘leak and fix’ is the norm, companies that construct pipe infrastructure with complete operational integrity from the outset get a financial head start. Simple engineering, procurement, logistics, installation and recycling, alongside a simply leak-proof capability, ensures DeltaV-Seal puts you in pole position.

If a formation of a potentially explosive atmosphere is to be expected surrounding the equipment, ATEX-zoning is mandatory according to ATEX-work Directive’ 99/92/EC. To avoid leaks leading to explosive atmospheres, 'Durably Technically Tight' solutions are viable according to EN 1127-1:2011.

DeltaV-Seal meet the criteria for Durably Technically Tight solutions, and by its nature it eliminates hazardous areas. These zones would otherwise require a pipeline to be re-routed around the area or the flange to be boxed in.

DeltaV-Seal features a solid metal design with a special focus on low lifecycle cost. Using a non-ductile, static, metal-to-metal design there is no need for re-tightening the bolts for the entire operational life span of the seal. The certified resistance to vibration, pressure pulses and temperature changes enables for an extended service life. In most applications, the DeltaV-Seal will last as long as the flange, pipeline or joint itself. As a result, the lifespan of your flanges can also be significantly extended, greatly reducing costs associated with flange replacement and planned shutdowns.

Avoid shutdowns

Avoid shutdowns

Leaks are dangerous, expensive and avoidable. For projects under construction or turnaround, leaks from bolted flange joints can severely disrupt schedules, causing delays, cost overruns, full shutdowns and, once production resumes, uncertainty. Any further leaks jeopardize profitable production and, with the potential for environmental damage and the need for emergency services, are an unnecessary burden on society. DeltaV-Seal is the solution industry has been waiting for.

Flange friendly

Through a matching metal, solid piece, gasket construction, corrosion detrimental to the flanges is completely eliminated. If a flange has to be opened due to planned maintenance, the DeltaV-Seal will release from its seating with ease without leaving any flange residue. The gasket will never degrade, enabling users to remove or inspect a flange without requiring any costly cleanings associated with competing ductile gaskets. This additionally eliminates any scraping from being performed on the flange face, further reducing the possibility of compromising the integrity of the flange.

Leaner pipework

The adaptive V-shaped ridges gently deform and adapt to the flange surface during installation. DeltaV-Seal seals with torque strengths as low as 17 Nm (35 % of required Equinor torque table for sheet gaskets). Additional EN 13555 leakage testing proved that after seating, the DeltaV-Seal showed a significantly lower level of leakage over competing gasket solutions. As a result, torque requirements are lower than competing gaskets, enabling the superior seal strength to be achieved without compromising the integrity of the flange or resulting in flange face deformation.
