,A prep-laced filler metal that is fully melted into the root of a welded connection
and becomes part of the weld is called: - ANSWER A consumable insert.
Define "face of weld". - ANSWER It is the exposed surface of a weld on the side
from whence it was created.
A category _____ fluid is neither flammable, harmless, or harmful to human tissue,
has a gage pressure of no more than 150 psi, and has a design temperature range of
-20 degrees to 366 degrees Fahrenheit. - Answer D.
A category ______ fluid has the potential for significant personnel exposure and
where a single exposure to a very small quantity of toxic fluid, caused by leakage,
can cause serious irreversible harm to people on breathing or bodily contact, even
when prompt restorative measures are taken. - ANSWER M
A fillet weld that is equal to the thickness of the thinner element connected is
called: - ANSWER A full fillet weld.
The heating and holding of metal to a suitable temperature and then cooling at a
suitable rate for such purposes as: reducing hardness, improving machinability,
facilitating cold working, producing a desired microstructure, or obtaining desired
mechanical, physical, or other properties is known as: - ANSWER Annealing.
A piping joint that provides mechanical strength through threaded, grooved, rolled,
flared, or flanged pipe ends, or bolts, pins, toggles, or rings, and leak resistance
through threads and compounds, gaskets, rolled ends, caulking, or machined and
mated surfaces is known as: - ANSWER: Mechanical joint
The word NPS 6 refers to: - A pipe with an outer diameter of 6.625 inches.
A pipe made by piercing a billet and then rolling, drawing, or both is called a: -
ANSWER Seamless pipe
, What is a root opening? - ANSWER It is the gap between the parts that will be
united by welding at the joint's root.
A weld designed primarily to ensure junction tightness against leaking in metallic
pipework is known as: - Answer: Seal weld
A tack weld is created to keep the components of a weld in perfect alignment until
the final welds are made.
The intersection between the face of the weld and the base metal is known as the
"toe of the weld."
The pressure in a piping system that is the pressure at the most severe condition of
coincident internal or external pressure and temperature (minimum or maximum)
expected during service (except for allowances for occasional variations in
pressure, temperature, or both, above operating levels, which are characteristics of
certain services) is known as: - ANSWER: Design pressure
Piping that is not protected by a pressure relieving device or that can be detached
from a pressure relieving device must be constructed for at least the following: -
Maximum pressure that can be created.
What happens if a piping system containing gas or vapor is allowed to cool
significantly? - ANSWER The pressure in the pipe system may drop enough to
create an internal vacuum.
