What does "fire hydrant SS100/65" mean?
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.
The path in the project often refers to a pipe diameter range of the known, such as: various types of pipe diameter for 15 pipe corresponding to the outer diameter of 22 or 20 (wall thickness of 0.4, 0.5, 0.6, 0.8, 1, 1.2, 1.4, 1.5, 1.6, 1.8, 2, 2, 2.5. 2.8) here path often refers to a range of pipe, instead of the mean diameter and the diameter of the.
SS100 indicates outdoor fire hydrant, inlet diameter 100mm, outlet quick interface is 65.Path defined: a conic (in addition to a circle), over the focus and perpendicular to the axis of the string.
