Types of Pipes used in the Oil & Gas Industry

This video gives you a not too technical understanding of the types of pipes used in the Oil & Gas and Petrochemical industries, to be more comfortable when discussing the topic with suppliers or technical counterparts.

The video shows:

  1. The characteristics of seamless, and welded pipes (ERW and LSAW)
  2. The manufacturing process of seamless, ERW, and LSAW pipes
  3. A Comparison seamless pipe vs. ERW pipe
  4. ASTM pipe specifications (A53, A106, API 5L, A333, A335, A312, A790, A928, and the various super-alloy grades): carbon steel pipes for high temperature, pipes for low temperature, alloy steel pipes, stainless steel pipes, duplex, and super duplex pipes, nickel alloy pipes
  5. Pipe dimensions: NPS, Schedule, lengths (SRL and DRL) and type of pipe ends (plain ends, beveled ends, threaded ends, threaded and coupled, grooved ends – i.e. Victaulic type)
  6. The dimensions of steel pipes per ASME B36.10 and ASME B36.19

Pipes Sizes Explained

Learn about the key sizes for steel pipe in oil and gas:

  1. What means “Pipe nominal size” and the different acronyms used to refer to this concept (NPS, ID, OD, DN, and NB)
  2. What is the pipe wall thickness (schedule)
  3. The reasons behind the ASME B36.10 and ASME B36.19 pipe dimensions standardization (introduced in 1927 to replace the IPS system)
  4. The difference between pipe ID and pipe OD
  5. Pipe length SRL and DRL – Type of pipe ends: plain, buttweld, threaded and threaded & coupled (PE, BE, TE, T&C)

Types of Valves for the Oil & Gas Industry

This video gives you a not too technical understanding of valves for piping (oil & gas), to be more comfortable when discussing the topic with suppliers or technical counterparts:

  1. What are the key types of valves used in the oil & gas industry?
  2. An overview of the function of valves: gate, globe, check, ball, butterfly, plug, pinch, control
  3. What is the valves’ face to face dimension as per ASME B16.10?
  4. An overview of the cast and forged materials for valves

Types of Fittings for Piping

This video gives you a not too technical understanding of fittings for piping (oil & gas), to be more comfortable when discussing the topic with suppliers or technical counterparts:

  1. What are pipe and tube fittings?
  2. Types of fittings; buttweld, socket weld, threaded NPT, branch outlet fittings (Olets, like Weldolet, Thredolet, Sockolet), instrumentation fittings (double ferrule fittings), mitered fittings
  3. Pipe fittings dimensions ASME B16.9, MSS-SP43, ASME B16.11, MSS-SP 97, A450, A1016
  4. Fittings materials: ASTM A234 WPB, A234 WP91, A403, A815, A860, A105, A350, A182 for stainless steel fittings and nickel alloys

Types of Flanges for Piping Applications

This video gives you a not too technical understanding of flanges for oil and gas and piping, to be more comfortable when discussing the topic with suppliers or technical counterparts:

  1. Types of flanges: welding neck, slip-on, socket weld, threaded, lap joint, blind
  2. Special types of flanges; swivel, expanding/reducing flanges, “Nipoflange” and “Weldoflange”, and orifice flanges, etc.
  3. Flange dimensions: nominal diameter, flange rating, schedule
  4. Flange material grades (ASTM): carbon steel flanges A105/A350, alloy steel flanges A182 F5/F9/F11/F22/F91, stainless steel flanges A182 F304/F316, Inconel/Incoloy/Hastelloy flanges (nickel-alloy)

  6. How flanges are manufactured
  7. Key specifications: ASME B16.5 and ASME B16.47

Types of Gaskets for Flanges

This video gives you a not too technical understanding of gaskets for flanges, to be more comfortable when discussing the topic with suppliers or technical counterparts:

  1. Non-Asbestos Gaskets: for low pressure/temperature applications
  2. Spiral Wound Gaskets: for medium/high pressure and temperature
