normally
✔✔start and stop flow - ✔✔the plug valve is used to
✔✔glove valve - ✔✔The most common valve used to regulate flow is the
✔✔make sure all piping is supported independently of the pump so that the pipe flange
puts pressure on the pump flanges - ✔✔A spool piece is to be made to fit a pump that
has been moved. The pipe will be field route to the flanges of the pump. which of the
following must be done to make this installation work properly?
✔✔check the size and rating stamped on the flanges - ✔✔How is the proper size gasket
determined for used with a set of flanges?
, ✔✔8 - ✔✔A 4" lateral riser for a 6" pipe is to be fabricated. How many ordinates lines
will be used to layout this cut?
✔✔remove pressure relief valves - ✔✔Which of the following should be done before
performing the hydrostatic test
✔✔stem - ✔✔A preventive maintenance schedule calls for a specific valve to be
lubricated. Grease is generally applied to which part of the valve?
✔✔temperature will directly affect a test - ✔✔which statement is correct about the effect
of water temperature on hydro-testing results
✔✔1.375 - ✔✔what is the decimal of 1/2" + 3/5" / 0.500"?
✔✔12" - ✔✔The domical size of a pipe and its outside diameter will be different up to
what maximum diameter?
✔✔an oxy acetylene torch - ✔✔thermal beveling of a pipe in preparation for welding
requires the used of
✔✔socket welded - ✔✔after a slip on flange slips over the end of the pipe. How is it
double welded to the pipe at the neck and at the face of the flange?
✔✔wrap adding machine paper around the pipe about 1-1/2 times. mark the paper
where it overlaps square cut the paper at the mark. Fold the paper three times. Make a
small angle cut at the corners to make notches - ✔✔a 14" 90 degree saddle is to be
made for a 18" heater. The regular wrap around is not available. Which procedure or
statement below is correct about making and using a temporary wraparound to layout
the ordinate lines?
✔✔6" - ✔✔What is the take off for a 4" x 3" LR reducing 90 degree ELL?
✔✔Have at least half the bolts in the flange. Drop the gasket in the middle of the flange.
Place all of the bolts in the flange and then tighten the bolts. As the bolts are tightened
the gasket will center itself - ✔✔An installer is working on a 8" carbon steel, 300 LBs
raised face weld neck flange. How should the installer put a flexitallic gasket in this type
flange?
✔✔8" - ✔✔Given a 45 degree lateral is to be made on a standard weight 6" riser on a
10" diameter heater using a wraparound marked in eighths. How far from the end of the
pipe should the wraparound line be drawn?
✔✔Use an oxyacetylene torch, cut the hole with bevel sides slanted toward the middle
of the pipe. This will make it easier to fit the saddle and to give a head start on beveling
