1. 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. 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 con- ditions 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. 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. 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. 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. 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
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 compatibil- ity" 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 sub- stance 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.
, 8. 8. Inorder to get the bundle to line up with the shell side
gasket the best tool to use to lift the bundle is a?: Drift
pinTo line up a tube bundle with the shell-side gasket
during assembly or maintenance, a tool called a "drift pin"
can often be the best approach. While "bundle lifters" or
"tube bundle extractors" are
specialized tools designed to lift, extract, or insert tube
bundles in heat exchangers, boilers, or similar equipment, a
"drift pin" is used for more precise adjustments in the
alignment of components. The drift pin helps in accurately
positioning the tube bundle, making it easier to align it with
the shell-side gasket. As always, the exact tool and method
can vary depending on the specific design of the equipment.
Always follow manufacturer's guidelines and safety
protocols.
9. 9.How often should you inspect any type of rigging
device?: before each useRigging equipment should be
inspected prior to each use and also periodically inspected
in a comprehensive manner, ideally by a trained, competent
person. The exact frequency of these more thorough
inspections can vary based on the equipment used, its
frequency of use, and its exposure to wear and tear, but
many guidelines suggest a complete inspection at least
annually. Always follow your company's safety guidelines
and any applicable regulations.
