Oil & gas

Safety and emissions compliance are essential to the Oil & Gas industry. An industrial facility or refinery can face the possibility of having thousands of micro-leaks, and until recently the best practice has been to tolerate these leaks on an 'acceptable level'.


To some facilities the proper seal or gasket may seem like an afterthought in the grand scheme of oil and gas production. However, anyone who has ever experienced the costly downtime associated with seal or gasket failure knows these products are as crucial to the process as their larger-scale counterparts.

Applications

The DeltaV-Seal is the sealing solution that satisfies the requirements of the Oil and Gas industry, as it is effectively gas-tight, firesafe, blowout-safe, and tolerates extreme temperature fluctuation through upstream, midstream, and downstream operations. Utilizing a smarter seal not only means superior sealing performance, it also means a client can operate without ever having to clean a flange or having to maintain it, for the entire operational lifespan of the flange connection.

Piping, flanged connections

The integrity of a pipeline is essential in the transportation and processing of oil and gas, as pressures and temperatures associated with production bring inherent danger to a facility and employees. Micro-leaks or 'fugitive emissions' no longer skate under the radar of the EPA or other national environmental protection agencies.

Pressure vessels

A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. In the Oil & Gas industry, a pressure vessel is used as a recipient in which physical and chemical processes take place, (often at elevated temperatures and pressures). Leaks connected to a pressure vessel can be fatal and having the right gasket is a low insurance policy.

Heat exchangers

In crude oil refineries Heat Exchangers are used to transfer heat between two or more fluids. The fluids may be separated by a solid wall (tube) to prevent mixing. Depending on the exchanger type, may be separated or in direct contact.


Sealing large air-cooled heat exchangers can be challenging, as these heat exchangers are often prone to a lot of corrosion problems, vibration, exchanger leakage, and thermal leakage problems. These challenges are eliminated through a superior sealing strength.

Use cases

DeltaV-Seal™ performs under extreme marine conditions

By Jo Shailes • March 11, 2025
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.

DeltaV-Seal™ replaces kammprofile gaskets at critical distribution facility

By Jo Shailes • March 7, 2025
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. Typically, LPG is a mixture of highly volatile substances, ranging from mixtures of hydrocarbons propene, propane, butene, and butane.

Flare tip leakage is too hot to handle for the competition

By James Knights • March 7, 2025
Pipeotech was called upon to provide a solution for Flare Tip flange leak in the North Sea. 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.

Intergas exclusively use DeltaV-Seal™

By Jo Shailes • March 7, 2025
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. As a provider of services such as: LNG & LPG facility construction, control systems, and operation monitoring, Intergas AS understands the tremendous importance of utilizing the DeltaV-Seals unique sealing strengths. Their reliance on components capable of tolerating temperatures fluctuating from scorching, down to -160°C is integral in their operations.

DeltaV-Seal™ solved permanent leakage at processing plant

By Jo Shailes • March 21, 2019
Norway’s key processing plants used for the transportation and processing of gas and condensate/light oil has successfully sealed previously sustained leaks. Located in Kårstø, Norway it is one of the largest of its kind in Europe, it found itself plagued with leaks in its condensed steam piping system. After trying various gasket sealing solutions to stop the leaking flanges, the leaks were completely eliminated through the utilization of the DeltaV-Seal. The DeltaV-Seal offers a gas-tight, metal-to-metal solution that is capable of operating in extreme temperatures without developing deposits on the flanges.
