Sample NV C-1K Industrial Piping Practice Questions

Try these sample questions to test your NV C-1K Industrial Piping exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Per 2018 UPC Section 609.1, after steel or copper industrial water pipe is cut, the burred end shall be:
A.Left sharp so the next fitting bites the thread
B.Reamed to the full bore of the pipe or tube
C.Peened shut to increase wall thickness
D.Coated with oxygen before assembly
Explanation: UPC 609.1 requires burred ends to be reamed to the full bore so the cut does not leave a ridge that reduces flow, traps product, or starts erosion. Industrial water, steam-condensate, and process-water lines are sized on full inside diameter; a burr turns a 2-inch pipe into a smaller orifice.
2When making a taper-threaded steel joint on an industrial water or gas line, pipe-joint compound or tape shall be applied:
A.Only on the female threads so excess is forced into the bore
B.On the male threads only, kept out of the first thread if the listing requires it
C.On both male and female threads and smeared into the pipe ID
D.Never; threaded industrial joints must be assembled dry
Explanation: 2018 UPC Chapter 6 and Chapter 12 require standard taper pipe threads with approved compound or tape on the male threads. Putting dope on the female thread drives compound into the line, where it can foul valves, regulators, and food-process equipment. Keep the first male thread clean when the manufacturer or listing says so, so compound does not enter the bore.
3A 2018 UPC/UMC industrial water offset is made with two 45-degree elbows. If the required offset (center-to-center) is 10 inches, the travel (center-to-center length of the offset piece) is closest to:
A.10 inches
B.12 inches
C.14 inches
D.20 inches
Explanation: Travel of a 45-degree offset equals offset times 1.414 (the square root of 2). 10 × 1.414 = 14.14 inches, so 14 inches is the takeoff length. Using the offset itself (10 inches) or doubling it (20 inches) under- or over-cuts the spool and stresses the joints.
4A copper industrial potable-water line is joined to a galvanized-steel header. Per 2018 UPC Chapter 6, the dissimilar-metal joint shall:
A.Be made with a dielectric union or other approved insulating fitting
B.Be sweated directly copper-to-steel so the solder isolates the metals
C.Use a steel coupling and extra pipe dope
D.Be omitted; copper may never connect to steel under the UPC
Explanation: UPC Chapter 6 requires dielectric isolation where copper or copper-alloy piping joins ferrous piping in water service. Without an insulating union, coupling, or fitting, galvanic current eats the steel (the anode) at the joint. Solder and pipe dope are not electrical insulators.
5Per 2018 UPC Section 609.5, unions on industrial water supply piping that serve regulating equipment, water heaters, or conditioning tanks shall be installed not more than how far from that equipment?
A.6 inches
B.12 inches
C.24 inches
D.6 feet, if the union is accessible
Explanation: UPC 609.5 requires unions not more than 12 inches from regulating equipment, water-heating or conditioning tanks, and similar equipment that must be removed for service. The union lets the C-1K crew break the line without spinning the entire header.
6On a 4-inch Schedule 40 industrial process water line, a long-radius 90-degree elbow is preferred over a short-radius 90 primarily because it:
A.Uses less metal and is always cheaper
B.Reduces pressure drop and erosion compared with a short-radius turn
C.Eliminates the need for hangers on both sides of the fitting
D.Is the only 90-degree fitting the 2018 UPC allows
Explanation: A long-radius elbow has a center-to-face of 1.5 times NPS; a short-radius elbow is 1.0 times NPS. The gentler turn lowers velocity at the heel, so pressure drop and particle erosion drop. Industrial water, slurry, and food lines use long-radius 90s unless space forces a short-radius fitting.
7A 2-inch carbon-steel industrial chemical line will operate at 250 psi and 300°F. Which joint type is the most appropriate default for the straight-run joints?
A.Standard 150-pound threaded couplings with hemp packing
B.Butt-welded or listed high-pressure mechanical joints rated for the temperature and pressure
C.Soldered copper fittings adapted onto steel nipples
D.Solvent-cemented Schedule 40 PVC couplings
Explanation: Threaded 150-pound joints and soldered copper are not the temperature/pressure class for 250 psi / 300°F process service, and PVC is far above its temperature rating. Butt welds or listed mechanical joints selected for the design pressure and temperature keep the joint integrity that industrial piping requires.
8Per 2018 UPC Section 609.1, changes in direction of rigid industrial water piping shall be made:
A.By heating and kinking the pipe around a column
B.By the appropriate use of fittings, except copper or copper-alloy tubing may be bent with equipment that does not flatten the tube
C.Only with welded miters cut at 22-1/2 degrees, regardless of material
D.By flattening the pipe and folding it
Explanation: 609.1 requires fittings for changes in direction. The listed exception is copper or copper-alloy tubing bent with proper bending equipment so the cross-section is not reduced. Kinking, folding, or unlisted field miters on every material are not the UPC method.
9A 6-inch Class 150 raised-face flange on an industrial water header is being made up. The gasket shall:
A.Be a full-face sheet that covers the bolts even though the flange is raised-face
B.Be a ring gasket that seats on the raised face, with bolts tightened in a star pattern
C.Be omitted if extra pipe dope is used on the raised face
D.Be two stacked rubber rings of any material
Explanation: Raised-face flanges take a ring gasket that matches the raised face. Full-face gaskets belong on flat-face flanges; mixing them can crack a cast companion flange. Tighten in a star (crisscross) pattern so the gasket loads evenly and the joint does not leak at test.
10A 3-inch Schedule 40 steel spool needs two long-radius 90-degree elbows and a 48-inch center-to-center run between elbow centers. Using a long-radius takeout of 4-1/2 inches per 3-inch 90 (1.5 × NPS), the cut length of the straight pipe between the two welds is:
A.39 inches
B.43-1/2 inches
C.48 inches
D.57 inches
Explanation: Each long-radius 3-inch 90 has a 4.5-inch center-to-end. Subtract both takeouts from the 48-inch center-to-center: 48 − 4.5 − 4.5 = 39 inches. That is the pipe cut length between weld bevels. Leaving the piece at 48 inches makes the finished centers 57 inches and misses the hangers and equipment nozzles.
