CALCULATOR MODULE : ASME B31.3 Process Piping Branch Reinforcement   ±

Calculate ASME B31.3 process piping required branch reinforcement for welded and extruded branches.

The calculations are valid for right angle welded branches, angled welded branches ≥ 45 degrees, and right anngle extruded branches. Extruded branches must be used for high pressure piping. Use the workbook ASME B31.3 data tables to look up allowable stress data.

CALCULATOR MODULE : ASME B31.3 Process Piping Design Factor   ±

Calculate ASME B31.3 process piping design factors (Y factor and W factor).

The Y factor is calculated from diameter for thick wall pipe (D/t < 6), or from temperature for thin wall pipe. The weld factor (W) is only relevant for design temperatures in the creep range. For design temperatures below the creep onset temperature W = 1. The weld factor does not apply for seamless pipe (W = 1).

CALCULATOR MODULE : ASME B31.1 Power Piping Branch Reinforcement   ±

Calculate ASME B31.1 power piping branch reinforcement for welded and extruded branches. Refer to the figures for details (click the resources button on the data bar)

For welded branches the branch angle must be ≥ 45 degrees. The pad reinforcement area also includes any welds or saddles which are inside the reinforcement zone. The extruded branch calculation is valid for right angle branches only. Use the workbook ASME B31.1 data tables to look up allowable stress data.

CALCULATOR MODULE : ASME B31.1 Power Piping Design Factor   ±

Calculate ASME B31.1 power piping design factors (Weld factor W, Y factor and thinning allowance B).

The Y factor is calculated from diameter for thick wall pipe (D/t < 6), or from temperature for thin wall pipe. The weld factor (W) is only relevant for design temperatures in the creep range. For design temperatures below the creep onset temperature W = 1. The weld factor does not apply for seamless pipe (W = 1). The thinning allowance (B) is an approximate estimate of the thinning on the outside radius due to bending (ASME B31.3 table 102.4.5). A power law curve has been fitted to the data values in the table. Use the workbook ASME B31.1 data tables to look up allowable stress data.

CALCULATOR MODULE : ASME B31.5 Refrigeration Piping Branch Reinforcement   ±

Calculate ASME B31.5 refrigeration piping required branch reinforcement for welded and extruded branches.

The calculations are valid for right angle welded branches, angled welded branches ≥ 45 degrees, and right anngle extruded branches.

Use the pipe wall thickness calculators to calculate design stress, minimum thickness and Y factor for the header pipe and branch pipe (use the user defined wall thickness option). Use the allowable stress calculators to calculate the design stress for the reinforcement pad. Use the workbook ASME B31.5 data tables to look up allowable stress data.

CALCULATOR MODULE : AS 2885.1 Pipeline Branch Reinforcement   ±

Calculate AS 2885.1 pipeline welded branch reinforcement using the replacement area method.

Branch reinforcement can be provided by pipe excess thickness, and by welded pad reinforcement. The reinforcement must be inside the reinforcement zone. Pad reinforcement can include additional equivalent width to account for welds, provided that the equivalent width is inside the reinforcement zone. The header, branch and reinforcement material should have similar properties. The reinforcement areas are factored if the branch or pad reinforcement allowable stress is less than the header allowable stress.
