Piping System and Elements

Piping Systems

  • Piping systems transport fluids between locations in a plant.

  • Components include pipes, fittings, flanges, valves, gaskets, insulation, bolts and supports.

Elements in Piping Systems

  • Pipes

  • Flanges: Used with fasteners, nuts, washers, and gaskets.

  • Gaskets

  • Bolting

  • Fittings: Connect pipe sections, change direction, add branches, or block ends.

  • Valves: Control flow and pressure.

  • Insulation, covering, coatings

  • Hangers & Supports

Piping Fittings

  • Joining Sections: Couplings, Reduced Couplings, Unions, Flange.

  • Changing Direction: 45° Elbow, 90° Elbow, Street Elbow.

  • Adding a Branch: Cross, Tee.

  • Blocking Ends: Pipe Cap, Blind Flange.

Piping Joints

  • Threaded joints

  • Soldered joints

  • Welded joints

Valves

  • Control flow and pressure, common types:

    • Butterfly Valve

    • Ball Valve

    • Gate Valve

    • Globe Valve (stem, bonnet, body, plug).

Check Valves

  • Prevent backflow.

    • Lift Check Valve (Lazy)

    • Swing Check Valve (Swinging)

    • Disc Check Valve (Door)
