In the imperial system of measurement, Pipe is referred to by its Nominal Pipe Size (NPS) in millimeters.

Inner Diameter of a pipe = Outer Diameter + 2 Wall Thickness

Pipe may be chosen with a thicker wall then necessary to counteract corrosion and erosion by the conveyed fluid. This extra thickness to counteract corrosion is called Mill Allowance.

A random length of pipe is 20ft.

Which of the following is NOT a typical pipe end preparation?

Since the inner diameter is fixed for a given pipe size, the outer diameter will vary depending on the wall thickness of the pipe.

For a NPS 10" sch 60 pipe, if the OD=10.75" and the WT= 0.5", the ID of the pipe is:

If for a NPS 1" sch 40 pipe the empty weight is 2 lb/ft, what is the empty weight of a double random length of this pipe?

For a NPS of 12" and higher, the NPS number = OD of the pipe.

Pipe sizes of 1¼", 2½", 3½" and 5" are the most common pipe sizes used in industry.

Piping is usually thinner in wall thickness than tubing

The three original wall thicknesses for piping were:

If the ID of a pipe is 100mm, what is the flow area of that pipe in mm² ?

Put answer as a function of $$\pi$$ e.g. $$10\pi$$
