Copper feed pipes |
| |
| a) |
The standard conditions
for material of construction and tests for copper pipes
shall comply with Regulation
35. |
| b) |
The maximum working pressure shall be determined by
the following formula:-
| W.P. = |
60(t-3) |
Eqn.(123) |
| d |
Where,
t = thickness in hundredths of an inch.
d = external diameter of the pipe in inches.

FEED PIPES
(a) Feed Heaters and similar vessels fitted to feed pipes |
Standard requirements,
materials of construction and allowable working pressure.
These shall comply with the requirements of Chapter
I, II and
III for riveted
construction. If so welded construction, such vessels
shall comply with the requirements of Chapter
XII, provided that radiographic examination of welds
may be waived, for pressures not exceeding 17.5 kg./cm.²
(250 lbs./sq. in.). For parts of vessels of composite
construction, the requirements of the appropriate regulations
of the above Chapters shall be complied with as may be
applicable to each such part. |

(b) Working Pressure |
| |
Working pressure of all parts
shall be determined by the appropriate formulae given
in these regulations. Due consideration shall be given
to the following additional points while calculating the
stresses.
The stresses due to self-weight of vessels and its contents
and any supper imposed vessel or other equipments, insulation
and these due to static head, if any and pipes and other
similar parts attached to the vessel. |
