Semi Conductor application for Nitrogen and Oxygen gas purifiers

James Knights • March 14, 2025

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.

Industry Challenges

The Kammprofile gaskets previously utilized could not provide reliable and extended service due to the high temperatures and required frequent shutdowns for replacement. Given the need for extremely high purity levels from the cleaned Oxygen and Nitrogen, the manufacturer also requested low levels of Carbon to be present within the gasket, which is met via the 316L DeltaV-Seal™. A tight and durable gasket was required to perform at high temperatures and provide a bacteria and virus-tight seal.

Background

The manufacture of semiconductors requires a clean room environment as the wafers produced are extremely sensitive to environmental containments. One of the world’s leading semiconductor manufacturers contacted Pipeotech looking to improve the performance of bolted flange joints, which are a strategic part of the system purifying Nitrogen and Oxygen. All flanges are raised face per ASME 16.5, and either pressure class #150 or #300 enables off-the-shelf DeltaV-Seal™ gaskets to be utilized required.

Benefits

Due to the leak-free, high-temperature performance, the DeltaV-Seal™ is now part of the best practice guidelines for one of the world’s leading semiconductor manufacturers, allowing higher operating temperatures for increased purity and advances in product performance. With the DeltaV-Seal™ providing an “off the shelf” delivery and simple fix, the semiconductor manufacturer is free to focus on increasing the manufacture of semiconductors to meet the global demand.

Solutions

Pipeotech’s 316L Stainless Steel gasket is the perfect fit. The fully metallic DeltaV-Seal provides a longterm, technically tight and durable high-temperature metal-to-metal seal, with all applications supported with a detailed engineering analysis per EN1591-1. The construction of the DeltaV- Seal™ allows for chemical cleaning as needed and, with zero filler material used, removes all concerns of; mechanical degradation, contamination and relaxation of the gasket.

Replacing legacy gasket technology to increase reliability and reduce maintenance costs

By James Knights • March 17, 2025
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.
