28mm will be the outside diameter. In the UK, depending on what BS standard the pipe is designed to, the thickness of the copper will be either 0.9mm or 1.2mm, the same as for 22mm pipe. assuming to thicker later type, then the internal diameter would be 28mm - (2*1.2mm) = 25.6mm

depends on liquid/gas and pressure. natural gas and high pressure = lots thick oil and low pressure = no much

The diameter of a pipe is its width across an open end of the pipe. The inside diameter is the width measuring on the inside of the pipe; the outside diameter is the width measuring on the outside.______________________________________________________________________________________________________For a pipe of circular cross section, its nominal diameter is the diameter of the cross section.The inner diameter is the measuring on the inside of the pipeThe outside diameter is the measuring on the outside of the pipe.

Calipers are used to measure the dimension of anarticle. In measuring a section of pipe you would use an inside caliper to give the internal diameter, and an outside caliper to give the external diameter. The difference being the thickness of the pipe wall.

The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.

I have recently had to join a 1 inch steel water pipe to a new copper 28mm pipe. You can do this using a 28mm comression joint. 1inch is just uneder 28mm in diameter but the compression joint takes up the difference and works without fault or leaks.

To provide an answer to this question the pressure of the fluid applied at the input end of the pipe must be provided.

NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.

The internal diameter of the pipe times pi times its length will yield the volume it can contain. The outer diameter of the pipe times pi times its length will yield the volume that the pipe will displace when it is submerged or buried. The volume the pipe will displace minus the volume it will contain will yield the volume of material that makes up the pipe.

Pipe Lining refers to the internal diameter, pipe coating is external.

bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.

It means copper tube size. More specifically, the outer diameter (O.D.) of the pipe being referred to is the same O.D. as copper pipe.

id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
