(REINFORCING PAD OF BRANCH CONNECTIONS)

With this method, you may design
· Reinforcement required for branch connections.

This method describes requirements for the design of reinforcement for branch connections of piping transporting liquids such as crude oil, condensate, natural gasoline, natural gas liquids, liquefied petroleum gas, liquid alcohol, liquid anhydrous ammonia, and liquid petroleum products between: producer´s lease facilities, tank farms, natural gas processing plants, refineries, stations, ammonia plants, terminals and other delivery and receiving points.

You may also obtain :

• Wall Thicknesses required (Header and Branch)
• 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 (Outside and reinforcing pad fillet-if required)

Furthermore you will be able to:

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

· Design Pressure (internal).
· Design Temperature.
· Thicknesses (Header and Branch).
· Diameters (Header and Branch).
· Material Specification : Header, Branch.
· Reinforcing Pad Material.
· Corrosion Allowance (Header and Branch).

NOTE: Allowable Stress Values are according to any temperature among -20°F to 250°F.
