(All dimensions in
mm)
Notes :-
The table is based
on metric series of pipe dimensions given in ISO 161/1 in respect of pipe
dimensin and ISO Dis4422.
The wall thickness
of pipes os based on a safe working stress of 8.6 Mpa at 27c and the working
pressure gets reduced at sustained higher temperatures. Occassional rise in
temperature as in summer season with concurrent corresponding reducttion in
temperature during nights has no deleterious effect on the life working pressure
of the pipe considering the total life of pipes.
For class 1, 2, and
3 of all sized, this requirement need not to be satisfied as the ratio of
minimum wall thickness to nominal outside diameter does not exeed 0.35 in these
cases. |
