2026 ALL QUESTIONS AND CORRECT
DETAILED ANSWERS ALREADY A GRADED
WITH EXPERT FEEDBACK |NEW AND
REVISED
What is the asme? What does section 1 of the asme code cover? -
answer- american society of mechanical engineers. People who write the
code books the brains they approve everything on construction and
design.
This code covers rules for the construction of power boilers, electric
boilers, miniature boilers, and high temperature water boilers to be used
in stationary service and includes those powerboilers used in
locomotives, portable, and traction service.
What is the scope of jurisdiction of section 1? - answer- section 1 applies
to the boiler proper and to the boiler external piping.
What is boiler proper? - answer- superheaters, economizes, and other
pressure parts connected directly to the boiler without intervening valves
shall be considered as part of the boiler proper, and shall conform to
section 1 rules.
( downcomers, risers, tubes etc...)
,2|Page
What is boiler external piping? - answer- boiler external piping is the
piping which begins where boiler proper terminates at up to the valve of
valves required by section 1.
The first circumferential joint for welded end connections, the face of
the first flange in a bolted flange connection, and the first threaded joint
in that type of connection
What is a power boiler? - answer- a pressure vessel constructed in
compliance with section 1 and in which steam is generated for use
external to the boiler, at a pressure exceeding 15 psig by the direct
application of heat.
Boilers with a maximum allow working pressure exceeding 125 psi what
are the requirements for valves and piping? - answer- you must have
extra heavy piping (schedule 80) and extra-heavy valves and/or cock
(250lb)
What's the lowest visible part of the gauge glass? - answer- at least 2
inches above the lowest permissible water level. Except hrt boilers 3
inches above the top row of tubes
What should the range of a pressure gauge be? - answer- 2 times the
safety valve set point, but in no case less than one and a half times.
(hydrostatic test)
How many water level indicators should boilers have? - answer- all
boilers should have at least one level indicator.
, 3|Page
Boilers over 400 psi shall be provided with two gauge glasses with
exceptions.(may be connected to a single water column)
Over 900 psi two independent remote level indicators may replace one
gauge glass
What type of valves are used between the water column and the boiler? -
answer- they must be os&y valve or lever type valves that indicate their
position whether they are open or closed. And they should be locked in
the open position. Also lines going to the water column should be fitted
with cross tees for inspection and cleaning
How often should flame scanners is be tested? - answer- minimum
weekly
What type of valves should a gauge glass be fitted with? - answer- quick
closing valves so they may be taken out of service quickly.
What are the requirements for a reheater safety valve? - answer- the
reheater safety valve(s)must be capable of relieving all the steam the
reheater can generate. At least 15% of the required capacity shall be
placed on the reheater outlet.
What is the minimum bearing width of a manhole gasket? - answer- 11
sixteenths of an inch
What is the minimum design temperature of a tube receiving heat? -
answer- 700°f
