Not exactly, but you can still connect them with proper fittings.
No-hub cast iron pipe is the same as hubless cast iron pipe. Both are terms used to identify a type of grey iron pipe that is manufactured for use in DWV and storm drainage applications. The terms "no-hub" or "hubless" refers to the pipes end. In contrast to "service weight" pipe, no - hub has no hub on the end and is joined using a no-hub coupling comprised of a 316 stainless steel shield with worm gears and a neoprene gasket. No hub pipe is manufactured to meet ASTM A 888 and CISPI (Cast Iron Soil Pipe Institute) 301 standards. To verify compliance you should use no - hub pipe and fittings bearing the NSF-upc (National Sanitation Foundation) mark.
Term used with cast-iron, PVC, CPVC and ABS pipe. Cast-Iron; The plain end of a cast-iron pipe. The spigot is inserted into the bell end of the next pipe to make a water tight joint. PVC, CPVC or ABS; A male end of a fitting the same size as the pipe that is inserted into the slip (hub) end of a fitting.
Yes OD never change
If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
1 inch to 20 inch Dia of pipe. Please answer me as soon as possible. If possible, give me equation for the same.
Three-quarter inch diameter pipe refers to the outside diameter. Different pipe types of the same outside diameter usually have different inside diameters. ASTM SCH 40 pipe of 3/4 inch diameter has an inside diameter of 0.824 inches. ASTM CL 200 pipe of 3/4 inch diameter has an inside diameter of 0.930 inches because of the thinner wall.
To calculate the weight of a foot (one linear foot) of 42-inch pipe, we need to know the pipe's material and thickness. Different materials and wall thicknesses result in different weights for the same size of pipe. For example, the weight per foot of a 42-inch steel pipe with a specific wall thickness will be different from the weight of a 42-inch PVC pipe with the same wall thickness. If you provide the specific material and wall thickness of the 42-inch pipe, I can help you calculate the weight per foot accurately. Otherwise, I can provide a general estimate based on a standard 42-inch steel pipe with a standard wall thickness, but keep in mind that this will not be precise for your specific pipe.
Yes.
It is based on the flow area, which is proportional to the square of the diameter. 2 squared = 4. 4 squared = 16. So, the 4 inch pipe can take 16/4 = 4 times the volume of the 2 inch pipe. It might be less confusing if you had picked sizes other than 2 and 4. This is a rough calculation, since pipe inside diameters are not the same as nominal sizes, but close enough for most purposes.
54 times MORE volume
Same as a 1/8 - 36 " pipe as STATIC pressure remins the same it is the "FORCE" which takes weight into account YOU need to have the pipe 23 feet high
Certain high pressure plumbing pipe will work for black powder guns, and is sometimes used by re-enactors. Do not attempt this without consulting with an expert. It can be lethal. Pressures on these rarely exceed 10,000 PSI "Zip guns" can be made out of a variety of pipe, but the same warnings apply. Early gun barrels were made from steeled iron wrapped around a form, or wound around a form (so-called "damascus" or twist barrels). Modern firearms use alloy steels which are forged and machined. Not poured and cast pig iron. The usual alloys are 416 stainless, or the 4130-4150 range of chrome-molybdenum steels. Modern gun barrels have to withstand up to 70,000 psi (pounds per square inch). Iron pipe is mainly used for rainwater soak aways... go figure
