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.
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.
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.
