Example:
Suppose a pipe of 300 mm inner diameter (DN300) and 5.5 mm thick. In the table we can
see that the distance that the insertion fitting must extend above the exterior wall is H =
60,5 - s = 60,5 -5,5 = 55 mm.
The values in the table are calculated with the gasket supplied with the instrument, which
is 3 mm thick. If the thickness of the gasket is changed, the value of
H
will change.
The equation to calculate H’ for a gasket of thickness
d
is the following:
H’ = H + 3 - d
In the previous example, if the gasket was 5 mm thick, the distance that the fitting should
extend above the exterior wall would be H’ = 55 + 3 - 5 = 53 mm.
