Select correct statement of design pressure of a vessel?
Design pressure is lower than operating pressure
A pressure which vessel can work safely or operate normally.
Design pressure is higher than MAWP
Design pressure is the pressure used in the design of a vessel.
Select correct statement of operating pressure of a vessel?
Operating pressure is lower than design pressure
The pressure used in the design of a vessel.
Pressure which pressure vessel can work safely or operate normally
Manufacturer recommended operating pressure on each equipment
Maximum Allowable Working Pressure (MAWP) is
lower than operating pressure
a pressure which vessel can work safely or operate normally.
lower than operating pressure.
Internal pressure at which the weakest element of the vessel is loaded to the ultimate permissible point
Pipe support helps to support the load of the piping system & prevent the pipe making direct contact with the ground which can cause severe corrosion problems.
Identify the type of pipe support in this figure.
wall bracket
dummy leg
saddle
U-section
Identify the type of pipe support in this figure.
Saddle
Dummy leg
Trapeze support
Bent flat bar
Identify the type of pipe support in this figure.
Trapeze
Saddle
Dummy leg
L-section
Purpose of insulation on the piping system
to prevent heat & temperature loss
to support pipeline system
to prevent external corrosion
to eliminate dust and debris from entering the pipeline
For underground piping, usually pipe will be wrapped or coated with
epoxy paint
polymer
bitumen
ceramic material
