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.

What is the best solution for valve release?

Oil and gas pipelines often pass over long distances through rough environments. They face exposure to temperature variations and other weather influences. The technology used must meet the highest quality standards. Manufacturers always have to ensure a smooth distribution of liquids and gases. Proper distribution helps them to avoid any leakages.

How to install a DBB Valve where a single isolation ball valve was previously installed?

For the most part, most engineers will start out by cutting the pipe in order to correct the dimension and weld new flanges on it. However, this daunting process can be avoided only if the DBB Valves conform to the ASME B16.10 End-to-End Dimensions. In other words, the DBB valves have to be manufactured or designed according to the ASME B16.10 Standard.

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”.

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/

3 mm are crucial to avoid overpressure

DBB valves with pressure relief hole or self-venting valve seats.

Pipelines that transport oil and gas over long distances often pass through rough environments. They are exposed to temperature variations and other weather influences. To ensure that the distribution of liquids and gases functions smoothly and that the medium does not escape, the technology must meet the highest quality standards.

Torque is more than meets the eye

DBB - Valve torque requirements for a safe process application.

When considering the torque values to operate the valve, one must consider how much torque is required to fully open and fully close the valve. If the valve gets stuck in mid function of opening or closing the valve a safety factor must also be considered sizing the actuator.

The Paradoxon of Dual Certified Material 316 / 316L

DBB - Paradoxon of dual certified material 316 and 316L.

When I started my career as a valve engineer, one of the first lessons were: Which materials are used for valve components. Didn`t know too much about the details of the different materials, for me, the most strange material at that times was the 316 Series.

Compact DDB Valves for Modular Plant Systems

DBB - Manufactoring compact valves for oil and gas industry.

Construction of modularized plant system has become a popular choice of design in heavy process industries like the Oil/Gas and Petrochemical Sector. Modularization is where equipment, vessels, piping, valves, instrumentation and electrical/controls are mounted on a compact steel framework, commonly called “skids”.
