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.
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.
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
Concentric swage is used for small bore piping while concentric reducer is used for large bore piping. Zach
NB stands for Nominal Bore.
A ball valve FFFE, or Floating Flanged Full Bore Ball Valve, is a type of valve that uses a spherical disc to control fluid flow through a pipeline. The "floating" design allows the ball to move slightly to ensure a tight seal when the valve is closed. "Full bore" indicates that the valve's internal diameter matches the pipe size, minimizing pressure drop and turbulence. These valves are commonly used in various applications due to their reliability, ease of operation, and ability to provide a tight seal.

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.
The diameter of the projectile.
Subtract 305 from 350 and that will give you the difference (or interval) between the two numbers:- the answer is 45. However, if you mean what is the difference between a Chevy 305 and a Chevy 350, then it is the difference between the engine bore (the cylinder) sizes. The 305 bore is 3.740 inches. And the 350 bore is 4.000 inches, giving the Chevy 350 20HP more then the Chevy 305.
The 67 has a rifled bore, the 67 smoothbore does not.
The size of the bore.
Primarily the bore size. The 305 has a bore of 3.74 and the 350 is a 4.0 bore. They share the same stroke on the crank. And no, you can't bore a 305 to a 4.0 bore.
Valve guide bore can be measured using a bore gauge. The bore gauge is inserted into the valve guide, and the measurement is taken by expanding the gauge until it makes contact with the inner walls of the guide. The bore diameter can then be read directly from the gauge.
A musket is smooth bored, like a shotgun's bore. A rifle has rifling inside the bore (grooves).
Caliber and bore are used interchangeably nowadays. There are technical differences you can find in the dictionary if you wish.
