LE 2 Incompressible Flow Of Pipes I

• 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.
