Rule 1980.
(1)
All new air receivers installed after July 28, 1995, shall be constructed in
accordance with the American Society Of Mechanical Engineers (ASME) "Boiler And
Pressure Vessel Code," Section VIII, "Unfired Pressure Vessels," 1980 edition
which is adopted by reference in
R
408.41902.
(2) All safety valves used shall be
constructed, installed, and maintained in accordance with the ASME "Boiler and
Pressure Vessel Code, Section VIII, "Unfired Pressure Vessels," 1980 edition,
as adopted in
R
408.41902.
(3) Air receivers shall be installed so that
all drains, handholes, and manholes are easily accessible. An air receiver
shall not be buried underground or located in an inaccessible place.
(4) A drain pipe and valve shall be installed
at the lowest point of every air receiver to provide for the removal of
accumulated oil and water. Adequate automatic traps may be installed in
addition to drain valves. The drain valve on the air receiver shall be opened
and the receiver completely drained frequently to prevent the accumulation of
excessive amounts of liquid in the receiver.
(5) Every air receiver shall be equipped with
an indicating pressure gauge that is located so that it is readily visible and
equipped with 1 or more spring-loaded safety valves. The total relieving
capacity of the safety valves shall be adequate to prevent pressure in the
receiver from exceeding the maximum allowable working pressure of the receiver
by more than 10%.
(6) A valve shall
not be placed between the air receiver and its safety valve or
valves.
(7) Safety appliances, such
as safety valves, indicating devices, and controlling devices, shall be
constructed, located, and installed so that they cannot be readily rendered
inoperative by any means, including the elements.
(8) All safety valves shall be tested
frequently at regular intervals to determine whether they are in good operating
condition.
