ASME B31.3 Process Piping Design Pressure

Calculate ASME B31.3 process piping design pressure for low pressure steel pipe (Table A-1), high pressure steel pipe (Table K-1), and plastic piping.

The design pressure is calculated from the pipe diameter, wall thickness, wall thickness tolerance and allowable stress (Table A-1 and Table K-1 US values : US units govern). The hoop stress is equal to the design stress at the design pressure. Change units on the setup page. Stress values can be extrapolated for temperatures above the data range (care is required when using extrapolated values). For combined internal and external pressure, the design pressure equals the pressure difference.

Use the Result Table option to display a table of design pressure versus wall thickness or design pressure versus material type. Use the Data Plot option to plot the design stress versus temperature for the selected material. Use the Data Table option to display the data table in the popup window (Table A-1, or Table K-1). Refer to the help pages for notes on the data tables (click the resources button on the data bar). Use the workbook ASME B31.3 data tables to look up allowable stress data.

Note : The choice of high pressure versus low pressure service is at the discretion of the owner (section FK300). The ASME B16.5 Class 2500 pressure temperature rating for the material group is often used as a criteria.

CALCULATOR : ASME B31.3 Pipe Design Pressure (General) [FREE]   ±

Calculate ASME B31.3 general pipe design pressure from diameter, wall thickness, wall thickness tolerance and design stress.

The hoop stress is equal to the design stress at the design pressure. The maximum design internal pressure includes the effect of external pressure (relevant for piping with external pressure only). For normal piping the external pressure should be set to zero.

For low pressure pipe, select the Barlow's equation with ASME Y factor option, with the pipe nominal diameter.

For high pressure pipe select the log equation option. For high pressure high temperature pipe the design stress should be divided by 1.155. The pipe outside diameter should be the maximum allowed by the code.

For plastic pipe use the Barlow's equation mid wall option, with the pipe nominal diameter.

For most cases external pressure can be ignored. Wall thickness negative tolerance can be defined by either a fraction tolerance, or an allowance tolerance (positive value).

CALCULATOR : ASME B31.3 Table A-1 Low Pressure Pipe Design Pressure From Temperature Alloy Steel Forging And Fitting [PLUS]   ±

Calculate pipe design pressure from temperature for low and medium alloy steel forging and fitting (ASME B31.3 Section 304.1 And Table A-1). The low and medium alloy steel allowable stress values (S) are interpolated from table A-1 (low pressure piping). The hoop stress equals the design stress at the design pressure. Use the Result Table option to display a table of design pressure versus wall thickness or design pressure versus material type. Use the Data Plot option to plot the design stress versus temperature for the selected material. Use the Data Table option to display the data table in the popup window (Table A-1, or Table K-1).

CALCULATOR : ASME B31.3 Table K-1 High Pressure Pipe Design Pressure From Temperature Carbon Steel Forging And Fitting [PLUS]   ±

Calculate pipe design pressure from temperature for carbon steel forging and fitting (ASME B31.3 Section K304.1 And Table K-1). The carbon steel allowable stress values (S) are interpolated from table K-1 (high pressure piping). For high pressure high temperature piping, the design stress equals the allowable stress divided by 1.155. The hoop stress equals the design stress at the design pressure. Use the Result Table option to display a table of design pressure versus wall thickness or design pressure versus material type. Use the Data Plot option to plot the design stress versus temperature for the selected material. Use the Data Table option to display the data table in the popup window (Table A-1, or Table K-1).

CALCULATOR : ASME B31.3 Section 304.1 Pipe Design Pressure From Wall Thickness (Low Pressure Steel Piping) [FREE]   ±

Calculate pipe design pressure from wall thickness for low pressure steel piping (ASME B31.3 section 304.1).

Allowable stress values should be taken from Table A for low pressure piping. If the D/t ratio is less than 6, or the P/SE ratio is greater than 0.385 check for the effects of fatigue and thermal stress etc. All user defined tolerances should be positive. The corrosion allowance should include mechanical allowance (eg threads), erosion allowance and any other allowances. The hoop stress equals the design stress at the design pressure. Use the Result Table option to display a table of design pressure versus wall thickness.

Note : The choice of high pressure versus low pressure service is at the discretion of the owner (section FK300). The ASME B16.5 Class 2500 pressure temperature rating for the material group is often used as a criteria.
