Reduce your VOC emissions with the DeltaV-Seal™

James Knight • March 14, 2025

Globally there is a drive to consume less and emit fewer damaging chemicals into the atmosphere. Within the United States, businesses are being called to reduce fugitive emissions by at least 30% before 2030.



There is a further global push for all countries to be net-zero emissions by 2050. The DeltaV-Seal™ has the potential to assist businesses in reducing their emissions and remaining compliant with their local laws meeting climate targets and improving their ESG Score Card value.

The United States Environmental Protection Agency (EPA) determined that leaking equipment, such as valves and connectors, is the largest source of volatile organic compound (VOC) emissions from petroleum refineries and chemical manufacturing facilities (EPA, 2007).


VOCs include many industrial chemicals such as benzene and solvents such as toluene and xylene (NJDEP New Jersey Department of Environmental Protection, n.d.). When leaked into the atmosphere, these chemicals create long-term climate effects. In the past, these emissions have not been well regulated, so the EPA implemented a program to promote the reduction of emissions (EPA, 2007).

– The EPA has estimated that approximately 70,000 tons of VOCs are emitted yearly from leaks contributing to smog formation (EPA, 2007).

Companies are required to reduce their VOC emissions through the Leak Detection and Repair (LDAR) program. LDAR regulation programs require companies to make equipment modifications and conduct regular monitoring to prevent leaks. With the proper implementation, companies are expected to reduce up to 96% of their emissions. Pipeotech's experience is that these programs can be costly to implement and only serve as short-term solutions given the degradation in performance of bolted flange joints sealed with traditional gaskets.

– 31% of uncontrolled VOC emissions in a petrochemical plant come from connectors (EPA, 2007).

PIPEOTECH offers a different solution while still maintaining LDAR compliance. Installing the DeltaV-Seal™, a fully metallic sealing flange gasket, into bolted flange joints can significantly reduce these emissions with a gas-tight seal, which has been subject to stringent 3rd party testing at temperatures between -196 °C and +880 °C (-320 °F and 1616 °F). Utilising the DeltaV-Seal™ ensures gas-tight sealing, technically tight, durable, long-term, and superior sealing performance that helps operators to meet their emissions targets and improve their ESG Score Card value.


In addition to reducing emissions from bolted flange joints and helping businesses meet their target climate goals, the DeltaV-Seal™ flange gasket has been proven time and time again to reduce significantly overall maintenance costs, eliminate unplanned shutdowns and improve overall HSE TRIR numbers.


Not only can we assist businesses in removing emissions Pipeotech can also increase reliability and reduce costs.

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

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.
