Piping Fundamentals. Piping Study. Piping Basic

Summary

This video explains the fundamentals of piping, including pipe materials, sizes, and key components. It covers how pipes are used to convey fluids, with nominal bore (NB) or nominal pipe size (NPS) for sizing. The transcript discusses various materials like carbon steel, stainless steel, and low alloy steel, each suited for different temperature and pressure conditions. Key piping components such as valves, flanges, elbows, and flow meters are also introduced, providing a solid foundation for understanding piping systems in technical applications.

Takeaways

• 😀 Piping refers to both pipes and components such as fittings, valves, flanges, and more.
• 😀 Pipe sizes are generally identified as Nominal Bore (NB) or Nominal Pipe Size (NPS).
• 😀 Pipes have fixed outside diameters (OD) but variable inside diameters based on the thickness selected.
• 😀 Common piping materials include carbon steel, stainless steel, low alloy steel, and low-temperature carbon steel.
• 😀 ASTM A53 covers welded and seamless black and galvanized steel pipes for general use.
• 😀 ASTM A106 specifies seamless carbon steel pipes for high-temperature surfaces.
• 😀 ASTM A672 deals with electric fusion welded steel pipes for high-pressure and moderate temperature applications.
• 😀 ASTM A312 covers seamless and welded stainless steel pipes for low-temperature services.
• 😀 ASTM A358 includes electric fusion welded austenitic steel pipes for corrosive and high-temperature services.
• 😀 ASTM A335 provides seamless ferritic alloy steel pipes for high-temperature services.
• 😀 Key piping components include valves, flanges, elbows, T-joints, reducers, flow meters, supports, hangers, strainers, and gauges.

Q & A

What is the main function of a pipe?

A pipe is a tubular product used to convey fluids from one location to another.

What does 'nominal bore' or 'nominal pipe size' refer to?

Nominal bore (NB) or nominal pipe size (NPS) refers to the identification system used to define the sizes of pipes.

How is the size of a pipe determined?

The size of a pipe is determined by its fixed outside diameter (OD) and variable inside diameter, which depends on the thickness selected.

What does the term 'piping' include?

Piping refers not just to the pipes themselves but also includes components like fittings, flanges, valves, bolts, gaskets, bellows, and more.

What are some common materials used in piping?

Common materials used in piping include carbon steel, stainless steel, low alloy steel, and low-temperature carbon steel.

What is ASTM A53 pipe used for?

ASTM A53 is a welded and seamless carbon steel pipe used primarily for general-purpose applications.

What is ASTM A106 pipe designed for?

ASTM A106 is a seamless carbon steel pipe used for high-temperature services.

What is the purpose of ASTM A312 stainless steel pipe?

ASTM A312 is a seamless and welded stainless steel pipe used for low-temperature services.

What does ASTM A358 refer to in piping?

ASTM A358 refers to electric fusion welded austenitic chromium-nickel steel pipe, designed for high-temperature and corrosive services.

Can you name some important piping components mentioned in the video?

Important piping components include valves, flanges, elbows, T-joints, reducers, flow meters, supports, stanchions, pressure gauges, expansion hangers, strainers, and struts.
