DeltaV-Seal™ prevent fires, promote safe environment

Jo Shailes • March 11, 2025

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.

The customer is a leading international manufacturer and supplier of paints and powder coatings with a total of 39 production facilities and approximately 10,000 employees worldwide. They have a presence in over 100 countries and supply paints and coatings specially developed for the residential, shipping and industrial markets.


The customer was experiencing regular gasket leakage in its hot oil systems, and as the company is invested in Health, Safety and Environment (HSE), this needed to be addressed to prevent facility fires, to increase efficiency and to ensure the safety of its employees.


Pipeotech proposed the DeltaV-Seal as an effective alternative to leaky traditional seals. The one-piece metal is machined in a compatible material to the connecting flanges, which completely mitigates seal failure due to temperature fluctuations. Not only does the seal achieve a phenomenal tightness at time of installation, the flange and seal expand and contract in unison providing a seamless and static connection that stays tight over time, regardless of the temperature.


The customer has had no leakages on their hot oil system since installation, which not only increases efficiency and reduces maintenance costs and downtime, but also provides a safer environment for its employees.

Replacing legacy gasket technology to increase reliability and reduce maintenance costs

Fertilizers are critical to enable the growing global population to be fed. Ongoing increases in energy prices, particularly methane, have made the cost of manufacturing nitrogen and ammonia-based fertilizers particularly high. Anything a manufacturer can do to reduce costs, reduce NOX emissions, and increase reliability has a positive global impact, ensuring a secure and long-term food supply while at the same time increasing reliability and reducing maintenance costs.

Replacing legacy semi-metallic gasket technology to prevent emissions of hazardous chemicals

By James Knights • March 17, 2025
Ammonium Nitrate is a challenging chemical to seal, in addition to being extremely hazardous. When Ammonium Nitrate emissions escape from bolted flange joints it crystalizes. These crystals of Ammonium Nitrate are a safety hazard and undesirable. Further to this the Ammonium Nitrate crystals can form inside the pipe, reducing flow and productivity. To remove the crystals of Ammonium Nitrate inside the piping, steam cleaning is utilized. This increases the degradation of legacy semi-metallic gaskets leading to an increased leakage rate, which results in more emissions, more crystals, and a cycle of avoidable costly maintenance.

Replacing legacy gasket technology to prevent the ingress of oxygen into a vacuum system

By James Knights • March 17, 2025
A leading chemical manufacturer sought a superior gasket to replace the current semi-metallic gasket utilized throughout this specific vacuum system. For this system it is crucial to prevent oxygen from entering the vacuum system as it would cause oxidation of the piping contents and compromise the entire batch of chemicals, leading to it being wasted. The DeltaV-Seal, known for its tightness and durability, prevents oxygen from entering the system through the bolted flange joints. This ensures that the product passed through the piping system is not contaminated by oxygen from the bolted flange joints, providing a superior quality end product.

DeltaV-Seal - Reducing fugitive emissions in the Permian Basin

By James Nights • March 14, 2025
The United States Clean Air Act (CAA) is the comprehensive federal law regulating emissions from stationary and mobile sources.  Among other things the CAA authorises the United States Environment Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) to protect the public health and public welfare as well as regulate emissions of hazardous air pollutants. The DeltaV-Seal effectively removes fugitive emissions fugitive emissions from connections, this case study details how.

COMSOL Multiphysics FEA Modelling of Gasketed Bolted Flange Joints

By James Knights • March 14, 2025
Imagine a future where in extreme environments it is possible to model and simulate a gaskets performance and know the lifetime of a bolted flange joint, sealed with a DeltaV-Seal. Pipeotech's Engineering and Technical team have been working to make the modelling and simulation of a gasket a possibility. Being able to simulate the performance of a bolted flange joint, and provide a defined lifetime has huge financial benefit to industry, maximising the time between turnarounds, extracting maximum value from their assets.

The simple replacement for Spiral Wound and Kammprofile gaskets

By James Knigjt • March 14, 2025
The DeltaV-Seal gasket replaces spiral wound and Kammprofile gaskets with a metal-to-metal seal without any of the challenges of traditional sealing technologies. As a metal-to-metal seal the leakage rate is extremely low, preventing fugitive emissions and ensuring we all breathe cleaner air.
