NB stands for "Nominal Bore" and refers to the nominal size of the valve in a piping system, typically measured in inches. It represents the internal diameter of the valve or pipe. It is an important parameter used to select the right valve for a specific application.
The next tidal bore on the River Dee in Flintshire is dependant on the tide cycle and specific conditions. It is advised to consult a tidal bore prediction chart or local authorities for the most accurate information.
The four English words that have the same spelling but different meanings are "lead" (metal versus to guide), "bow" (front of a ship versus a looped knot), "tear" (to rip apart versus a drop of water), and "wind" (to twist versus moving air).
The pH level of bore water can vary depending on factors like mineral content and surrounding environment. Generally, bore water has a pH level between 6.5 to 8.5, which is considered slightly acidic to slightly alkaline. Testing the pH of bore water is recommended to understand its specific characteristics.

Generally speaking, gate valves in larger sizes are full bore unless you order a reduced port. You would always use a full bore gate valve for hot tapping purposes. or you would use a full bore gate vale for runinig a pig in pipeline.
In Full bore ball valve, The bore dia will be same as internal dia of the pipe.In reduced bore, the bore dia is reduced than the ID of pipe.
For Ball valve only,as it gives more full bore flow,unlike wedge block,slow operating in Gate valve.
NB is nothing but Nominal Bore.

They would not generally release that information to the public.
valves are available in three types first is full bore equal to 100 percent opening normal bore/port equal to 80 percent opening reduced bore equal to 60 percent opening
This is a tool used to align the cleaning rod with the bore so that it doesn't rub against the sides of the bore when you pull the cleaning rod in and out. This prevents damaging the bore during cleaning.
Inside micrometer
Use full bore for applications where pressure drop should be minimum (such as in the suction pipe of a pump with required NPSH very close to available NPSH), or for pipes which could be cleaned with a pig (so that the pig doesn't get stuck on the valve). In other applications a reduced bore should be OK.
A bore gauge is a tool used to measure the sizes of various holes. There are no different kinds of bore gauges, but bore gauges do come in a few different sizes.
