Improved isolation of fluid systems for maintenance work

Infographic about DBB Valves in a Bypass Application.

Customer listening is an essential topic at AS-Schneider. AS-Schneider technicians often visit customers together with their sales colleagues to discuss daily challenges, issues and success stories. One point we came across at a customer visit of the gas storage plant “Jemgum” (astora GmbH & Co. KG) in northern Germany is how to take care of maintenance and repair operations in technical plants. In this article, we would like to describe how DBB Valves used in a bypass application provide a solution that can help you saving maintenance and replacement costs.

International Standards that recognize and mandates the use of DBB Valves

DBB – Norsok and OSHA are international standards for energy isolation.

Industry giants with the likes of Shell, Exxon, BP, Total and any major players for that matter, have rules and standard set in place dedicated to one subject area called Energy Isolation. Energy source could be in various form such as electrical, heat or pressure energy. Different companies and state agencies will have varying regulations and engineering practices for system or equipment isolation during maintenance and intervention. Nevertheless, regardless how minor or how critical the isolation requirement, the objective is to always meet the minimum “safety requirements”.

Smart DBB Valve Technology

DBB - Endusers have cost reduction of 30 percent.

DBB Valves: Traditional installations of DBB Valve systems at plants are very time consuming and an expensive practice. A traditional system consists of two single ball valves, a needle valve, various connectors, adaptors and flanges. There are many steps to consider when completing the installation process. In total, there can be as many as 41 steps required for a traditional installation of DBB valves setup.

OSHA Standards – Occupational health and safety

DBB - Valves meet OSHA Standards for occupational health and safety.

Safety requirements in the process industry are extremely high. In some plants, especially in processes, involving flammable liquids or toxic gases, such a leakage can lead to risks to the plant but much important to the personnel – Especially for engineers with focus on maintenance and facility. The DBB Valves made by AS-Schneider provides an added value for all fields of application: https://taurusdbbvalves.com/features/

The Advantantage of using a compact DBB Valve

DBB - Benefits and advantages of a DBB assembly in oil and gas industry.

In the Oil/Gas industry, although it has become very common, the use of a compact Double Block & Bleed (DBB) valve for pressure energy isolation is still not applied or adopted across the board. I have experienced a few times wherein the use of a DBB valve for process isolation is more of an option rather than a design requirement.
