The DeltaV-Seal is helping operators in the Permian Basin reduce their fugitive emissions.

A market-leading expert for the maritime industry manufactures a range of inert gas generators to suit their client's needs. Vessels carrying cargo-producing hydrocarbon vapors require inert gas generators to remove flammable and explosive atmospheres from their cargo tanks.

On a Thermowell instrument coupling flange joint a previous semi-metallic gasket required maintenance intervention 7 times in three-and-a-half years. Switching from a semi-metallic gasket to the DeltaV-Seal prevents the emissions of NOx, protecting the environment and will saving the operator the cost of regular maintenance interventions.

One of the world's leading semiconductor manufacturers in South Korea required a carbon-free, bacteria and virus-tight gasket capable of withstanding temperatures up to 500°C. The DeltaV-Seal™ gaskets are now utilized within many operating systems, including tube-type heat exchangers for Nitrogen & Oxygen gas purification.

Recycling metallic canisters containing flammable gases to prevent the emission of the gases to the environment and recycle the metallic packing material.

Increasing plant safety and lowering emissions is simple with the DeltaV-Seal. Working with several international standards a food manufacturing facility was able to reduce ATEX zoning around their bolted flange joint within their biogas plant.

Ensuring product quality and plant safety with a clean, bespoke, tight, and durable seal. The DeltaV-Seal enabled a manufacturer of peroxide to ensure their product was made safely and was free of contamination.

Recycling plastic into hydrocarbons requires extreme pressures and temperatures, challenging the performance of traditional gaskets. Before contacting Pipeotech, a university had been utilizing Kammprofile gaskets which consistently failed at around 80 Bar G pressure during trial operations. Ensuring a reliable seal was essential to confirm proof of concept, and this was made possible with Pipeotech’s engineering expertise and the DeltaV-Seal™ flange gasket.

Methane is one of the most potent greenhouse gases and avoiding leakage is a priority when using methane systems. Methane also ignites easily, so there are clear and immediate HSE incentives for maintaining absolute process integrity. Traditional pipeline gaskets often leak and need frequent maintenance, which must be considered when choosing seals for a methane system.

In manufacturing fertilizer, ammonium nitrate is added to the process, and traditional, spiral wound and Gylon gasket technology often deteriorate in these conditions, resulting in leaks. This is problematic because when ammonium nitrate leaks, it crystalizes and expands like ice, resulting in costly repair and safety hazards.

During final assembly in the factory, cars are filled with fuel before being transported to their final destination. To facilitate this, fuel lines run throughout the facility. However, along the piping route there are potential sources of ignition, which is problematic when traditional seals cause leakage of flammable materials.

In facilities that use hot oil heat transfer fluid systems, fire hazards are a significant challenge due to the combination of organic combustible liquids, which run at temperatures above their flash point, making them volatile, and failing gaskets in the system. Many industrial fires and plant explosions can be traced back to the integrity of heat oil transfer fluid systems, where seals in disrepair are a significant source of preventable leakages.

The use of hot oil systems in manufacturing presents challenges when traditional gaskets breakdown and cause leakage. As liquids in the system are kept at a temperature above their flash point, when they escape they can cause fires and even explosions in the facility.

In district heating and cooling, generic spiral wound gaskets frequently cannot cope with the cyclical temperature conditions and often fail, leading to leakages and corrosion of the pipeline. This causes expensive maintenance and lower overall performance.

Importing ship-to-shore Liquefied Natural Gas (LNG) requires robust and efficient pipeline seals that are compliant with high environmental standards. The thermal cycling caused by the cryogenic nature of LNG, as well as the unpredictable marine environment, demands a seal that stays incredibly tight under extreme conditions in order to reduce leakage and to transfer on schedule.

In fertilizer production, high-quality phosphorus fertilizers require nitric acid as a key ingredient, which is usually synthesized via the Ostwald process on-site (oxidizing of ammonia before combining with water). This form of nitric acid synthesis is a cornerstone of any modern fertilizer production facility. However, this process can cause nitrous oxide to leak from the nitric acid lines, and it is 296 times more potent than carbon dioxide.

Pipeotech has taken gasket tightness to new microscopic levels by supplying DeltaV-Seal™ to European Spallation Source, the world’s most powerful neutron source, in Lund, Sweden.

I am a departmental engineer in the technical engineering department with equipment responsibility for pipes, valves, gaskets and tanks. In addition, I am responsible for pipes and mechanical disciplines in a number of projects. I’ve been employed at Lindesnes for almost 20 years

Norwegian-based shipbuilder VARD has been installing Pipeotech’s DeltaV-Seal™ in its vessels since 2016 and the cost-saving benefits have been very clear to Johny Morland, Principal Engineer, QA and Standardisation at the Fincantieri-owned company.

With the title of ‘the oldest brewery in Norway’, the Aass brewery is about as close as it gets to being a Norwegian institution. Situated on the banks of the river in the busy port city of Drammen in central Norway, this family-run enterprise has been producing a wide range of beers, ciders, spirits and non-alcoholic beverages for the Norwegian domestic market for over 180 years.

After a long relationship utilizing kammprofile gasket technology, Norwegian LPG distributor PrimaGaz Norge AS has decided to abandon the old kammprofile gasket design in favor of the new DeltaV-Seal gasket technology. Primagaz’s operations are based around the storage and transport of LPG gas.

A North Sea Operator came to Pipeotech with a problem affecting a Flare line on their platform. This was due to the dynamic operating conditions caused by a phenomenon called internal burning. This occurs when the internal flare line stabilizes inside the flare tip, at temperatures around 400c, and cannot be driven out without a substantial increase in flaring rates. During blowdown the tip is quenched down to -50c and this rapid change in temperature provides a huge challenge for any traditional gasket to seal for a long period of time.

Following a highly successful test period, Intergas AS has announced that the DeltaV-Seal has been named as their exclusive seal of choice for all current and future liquefied natural gas operations.

With its primary objective to reduce the risk of leaks, environmental contamination, and maintenance costs, Fortum Oslo Varme announced its decision to utilize Pipeotech's next-genDeltaV-Seal™ sealing solutions in these three locations in Oslo.

After trying various gasket sealing solutions to stop the leaking flanges, the leaks were completely eliminated through the utilization of the DeltaV-Seal.
