NCCER Test Boilermaker Exam
Questions With Correct Answers
1. Which organization requires a person to be trained in order to operate personal
lifting equipment?
OSHA The Occupational Safety and Health Administration (OSHA) requires that persons
operating personal lifting equipment, or any kind of machinery, must be properly
trained. This includes training in the operation of the equipment, understanding the
hazards associated with its use, and the implementation of safety precautions to
prevent accidents and injuries.
2. Where would the usage of a RTJ Gasket be found?
high-pressure and high-temperature systems Ring Type Joint (RTJ) gaskets are often
used in high-pressure and high-temperature systems, such as oil and gas industry
pipelines, valves, and pressure vessels. These gaskets are designed to withstand harsh
conditions and provide a robust seal. They are typically used in flanged connections that
have grooves designed to accommodate the RTJ gasket, providing a metal-to-metal seal.
3. All of the following are examples of internal manway hardware except?
"slide fastener" Internal manway hardware typically includes components such as cover
plates, yokes, wing nuts, hinges, gaskets, and bolts. In this context, all these are
,examples of internal manway hardware, but a "slide fastener" is not typically part of the
internal manway hardware. A slide fastener is a more general term that could refer to
various types of fasteners, such as zippers, which are not typically found in manway
hardware. Therefore, a slide fastener would not be considered an example of internal
manway hardware.
4. What type of wrench measures how much a fastener is being tightened?
"torque wrench" The type of wrench that measures how much a fastener is being
tightened is known as a "torque wrench". This tool allows the user to set the amount of
torque applied to the fastener, providing a precise level of tightness. It's critical for
applications where the tightness of screws and bolts is crucial.
5. the fitting that makes it easy to disassemble threaded piping is?
"union" The fitting that makes it easy to disassemble threaded piping is commonly
known as a "union". A union fitting allows two parts of a pipe assembly to be taken
apart without needing to move other components, making it especially useful in tight
spaces or complex assemblies. This can greatly simplify tasks like maintenance and
repair.
6. what is the purpose of a gasket?
to create a seal between two stationary parts A gasket's primary purpose is to create a
seal between two stationary parts. It fills the space between two or more mating
surfaces, usually to prevent leakage from or into the joined objects while under
, compression. Gaskets can be made from a variety of materials, depending on the
specific application and the type of fluid or gas that needs to be contained. They are a
crucial component in a wide range of mechanical and industrial processes.
7. What is the 1st consideration when making a gasket?
"material compatibility" The first consideration when making a gasket is the "material
compatibility". This refers to selecting the appropriate gasket material that can
withstand the operating conditions where the gasket will be used. Material
compatibility includes considering:
1. The type of fluid or gas that the gasket needs to contain.
2. The operating temperature and pressure.
3. Any potential chemical interactions between the gasket material and the substance it
is sealing.
4. The type of connection (flange type, bolt pattern, etc.)
These factors are crucial as they will dictate the type of material you should use for the
gasket. It's important to ensure that the chosen material is compatible with the
operating conditions to prevent failures and ensure safety and longevity of the gasket.
