DOUBLE BLOCK AND BLEED VALVES
SOLVING PIPING ISSUES
Get insights how DBB Valves help you to overcome the toughest conditions in
the plant – for safety process application and save installation costs in a plant.
ASME B16.10 FOR A
Double Block and Bleed Valve?
Please consider the following situation: Due to increased safety requirements you, as piping engineer, get the task to change all single ball valves in a specific application to a DBB Valve. Presumably your first thoughts are:
“Oh my gosh, how many flange connections are affected:”
The major benefit of a DBB Valve is that it has the same face-to-face dimension as a single block ball valve. The length of a single block ball valve is specified in ASME B16.10 and APl 6D.
As a consequence the valve can easily be installed into an existing pipeline without the need for any re-work on the pipeline.
PLANNING AND MODERNIZATION WORK
As piping engineer, you have the possibility to exchange already installed single ball valves with DBB Valves without taking care of all the action which is necessary to adjust the distance between the two flanges of the pipeline.
PIPING AND ENGINEERING ISSUES
As a pipeline engineer, you must not only have a broad engineering knowledge, but also an understanding of engineering economy and costs, of material metallurgy, of manufacturing and assembly processes in the oil and gas industry or other industries.
Get insights how DBB Valves help you to overcome the toughest conditions in the plant, such as high temperatures, pressure and flow as well as combination of these – for safety process application. And at the same time save installation costs for piping, instrumentation and accessories in a plant.
