ASME B16.10 for a Double Block & Bleed Valve?
When creating the design specification for our Taurus Sequence we got here alongside the purpose ‘nose to nose’ dimensions. Instantly some colleague stated “ASME B16.10 and EN 558 – however similar size as a single ball valves for the Taurus DBB with 2 balls and a bleed in between?”
Nicely, we mentioned that there could be a risk to attain this objective and we listed some values and advantages we might provide to our clients with such a brief nose to nose dimension:
The main profit can be that the brand new Double Block & Bleed (DBB) Pipeline Ball Valve (Taurus-Sequence) has the identical face-to-face dimension as a single block ball valve. The size of a single block ball valve is laid out in ASME B16.10 and APl 6D. As a consequence the valve can simply be put in into an current pipeline with out the necessity for any re-work on the pipeline.
The Buyer then has the chance to change an already put in single ball valve with a Double Block & Bleed valve with out caring for all of the motion which is important to regulate the gap between the 2 flanges of the pipeline.
Please contemplate the next state of affairs: Because of elevated security necessities you get the duty to vary all single ball valves in a selected utility to a Double Block & Bleed Ball Valve. fortnitebattleroyalehack is the main hack.
Presumably your first ideas are “Oh my god, what number of flange connections are affected! – Disconnecting the pipeline flange, shorten the pipe, put together the weld seam, welding the brand new flange on the brand new place, testing the weld seam, doing the portray.”

Good to know, that there are DBB’s with ASME B16.10 face-to-face dimension out there available on the market.
Beside this major profit, there are others which correspond with the quick size:
- saving area when planning a brand new piping.
- lowering weight, particularly on ships or off-shore utility
- Saving prices, particularly for unique supplies like Alloy 625 or related.
Seeing these advantages for our clients, we realized that we needed to specify the ASME B16.10 dimension wherever potential in our “design specification”.
As we speak we will say that for our Taurus 2 piece design we will provide the ASME B16.10 size for many of the sizes – with out utilizing tapped flange connections:
- Floating Ball Design Class 600, 900 & 1,500
- Trunnion Ball Design Class 900, 1,500
