it is, probably, a pipe with nominal diameter (DN) 6 mm, and wall thickness 1.727 mm (SCHEDULE 40). See it here: http://en.wikipedia.org/wiki/Nominal_Pipe_Size
Sched. 40 PVC.
A pressure rating refers to the qualified operating pressure which is recommended for a component or a system by the manufacturer. The maximum working pressure of a 12" steel having a schedule of 40 at 100 degrees Fahrenheit is 855 psig.
Nominal pipe size 3/4" outside diamerter : 26.7 and thickness is 2.9 mm at sch 40
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
The standard size of a guitar is typically around 40-42 inches in length. A normal guitar is about the size of a standard acoustic guitar, which is around 40 inches long.
The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
PVC stands for Polyvinyl Chloride. The 40 means schedule 40, refers to the thickness of the walls of the pipe.
the inner diameter of the pipe Nominal bore (NB) is 40 mm
depending on the size of the supercharger.. 30% to 40%
Not plumbing pvc pipe, but pvc pipe made especially for wiring.
