REINFORCEMENT REQUIRED FOR OPENINGS*
(single-walled vessels)
(REINFORCING PADS)

With this method, you may design for internal pressure:   · Reinforcement required for openings in cylindrical shells.

  You may also obtain :

• Wall Thicknesses required (Shell and Nozzle)
• Area of Reinforcement required
• Area of Reinforcement available
• Cross-sectional area of various welds available for reinforcement
• Cross-sectional area of material added as reinforcement
• Total Area Available
• Size of reinforcing pad (if required)
• Size of fillet welds (Inside, outside and reinforcing pad fillet-if required)
• Maximum Nozzle distance projects beyond the inner surface of the vessel wall, less Corrosion allowance.

  Furthermore you will be able to:

  · Check your existing openings for different conditions .
  · Check your reinforcement of openings design modifying some one of the parameters as follows:

· Design Pressure (internal).
· Design Temperature.
· Thicknesses (Vessel and Nozzle).
· Diameters (Vessel and Nozzle).
· Allowable stresses (Materials:Vessel, Nozzle and Pad).
· Joint Efficiency.
· Angle of plane with longitudinal axis.

  NOTE : This method applies to all openings other than:

• Openings in flat heads.
• Openings designed as reducer sections.
• Large head openings.
• Tube holes with ligaments among them.
• Large Openings in cylindrical shells.
