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.
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.
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”.
Welcome to the world of Modular Plant Systems. Construction of modularized plant system has become a popular choice of design. Especially in heavy process industries common to the Oil & Gas and Petrochemical Sector. Generally, such modularizations are used for compact steel frameworks commonly called “skids”. For example when equipment, vessels, piping, valves, instrumentation and electrical/controls are mounted. A complete system may comprise a single skid or a number of skids to form a bigger and sophisticated processing system.
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.
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/
