LE 2 Incompressible Flow Of Pipes I

Cards (35)

  • Identify the fitting
    Coupling
  • Screwed or threaded fittings are connections that are rimed with matching grooves, one of the outside of a piece and the other on the inside.
  • Valves are piping elements that are used to control the flow rate or shut off the flow.
  • Fittings are adjoined pieces whose function is to join 2 pipes, to change the pipeline direction, to change the pipeline diameter, to terminate a pipeline, or to create a new pipeline from combining 2 pipes.
  • Gate valves work by inserting a gate or wedge into the path of a flowing fluid. They are designed for fully open or fully closed services and should not be used as control or regulating valves
  • What should gate valves not used to?
    Control or regulatory valve
  • A flanged fitting involves joining two pieces of material by means of an internal or external lip.
  • Globe valves are a linear motion valve used to stop, start, and regulate the fluid flow. The disc that prevents flow is arranged parallel to the flow.
  • Unlike the gate valve, the globe valve can be used to regulate flow or pressures
  • Check valves are also known as non-return valves or one-way valves.
  • Check valves are automatic valves that allow fluids to flow through them in only one direction.
  • The prime function of a check valve is to protect mechanical equipment in a piping system by preventing reversal of flow by the fluid.
  • Butterfly valve are rotary valves in which the disk that regulates flow is rotated on an axis to open or close the flow passage.
  • Butterfly valves are used in throttling services, particularly when large-size valves are required.
  • The seal of a diaphragm valve is achieved by a flexible membrane.
  • The operating parts of the valve are isolated from the flow, which makes diaphragm valve suitable for viscous, hazardous, abrasive, and corrosive flows.
  • Ball valve is a shut-off valve that controls the flow of a fluid by means of a rotary ball having a bore.
  • The connection to the source tank is called the pipe entrance.
  • The connection to the destination tank is called the pipe exit.
  • Changes in velocity result in form friction (also known as minor losses), which must be accounted for in the design of piping systems.
  • Skin friction is quantified by determining the friction factor.
  • Form friction is quantified by determining the loss coefficient.
  • Identify the fitting - 90 deg threaded elbow
  • Identify the fitting - union
  • Identify the fitting - coupling
  • Coupling and union are fittings that is used to connect 2 pipes
  • Identify the fitting - wyes
  • Identify the fitting - tees
  • Tees and wyes are fittings that is used to connect 2 pipes to form an another pipeline
  • Identify the fitting - bushing
  • Identify the fitting - plug
  • Identify the fitting - return bend
  • Identify the fitting - expanders and reducers
  • Return bend and 90 deg threaded elbow are fittings that is used to change the pipeline's direction.
  • Bushings, expanders, and reducers are fittings that is used to change pipeline diameter.
