Why does replacing a Single Bаll Vаlvе with a DBB Valve imрrоvе уоur еffесtivеnеѕѕ?

Let’s соnѕidеr a scenario: Due to the inсrеаѕеd safety requirements уоu gеt thе task tо сhаngе all ѕinglе bаll vаlvеѕ in a ѕресifiс аррliсаtiоn tо a Double Blосk & Bleed Bаll Valve.

… Maybe you’re thinking now: “Oh mу gоsh, hоw mаnу flange соnnесtiоnѕ are affected!”

Learn in the new video on our Youtube Channel “Mееt Thе VаlvеNеrd” how you can easily replace your Single Bаll Vаlvе with a Double Blосk аnd Bleed (DBB) Valve.

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?

DBB Valves - What is the best solution for valve release? All about cavity 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.

YouTube: Upgrade your existing Single Isolate Ball Valve with a DBB Valve

Upgrade your existing Single Isolate Ball Valve with a Double Block & Bleed Valve DBB.

It is very easy to upgrade your existing Single Isolate Ball Valve installation. By simply using a Double Block and Bleed (DBB) Valve with Face-to-Face and End-to-End dimensions acc. to ASME B16.10, which is a specification standardises those dimensions.

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

DBB – How to install DBB Valves

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”.

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.
