ASME B31.3 Process Piping Wall Thickness

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

Allowable stress for steel pipe is calculated from Table A-1 and Table K-1 US values (US units govern). Change units on the setup page. Stress values can be extrapolated for temperatures above the data range (care is required when using extrapolated values). The wall thickness calculations are valid for internal overpressure only. For combined internal and external pressure use the pressure difference in the calculations.

Use the Data Plot option to plot the allowable 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). Use the Result Table option to display a table of wall thickness and allowable pressure versus material type (for the calculate wall thickness option the allowable pressure equals the design pressure. for the specified wall thickness option the wall thickness equals the specified wall thickness). Refer to the help pages for notes on the data tables. Change units on the setup page. Use the workbook ASME B31.3 data tables to look up allowable stress data.

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

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

Pipe wall thickness can be calculated from either the outside diameter (constant OD pipe), or the inside diameter (constant ID pipe). 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.

CALCULATOR : ASME B31.3 Section K304.1 Pipe Wall Thickness From Hoop Stress (High Pressure Steel Piping) [FREE] ±

Calculate pipe wall thickness for pressure containment for high pressure steel pipe (ASME B31.3 section K304.1).

Pipe wall thickness can be calculated from either the outside diameter (constant OD pipe), or the inside diameter (constant ID pipe). The maximum allowable diameter should be used. Allowable stress values should be taken from Table K for high pressure piping. All user defined tolerances should be positive. The internal and external corrosion allowance should include mechanical allowance (eg threads), erosion allowance and any other allowances.

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. The high temperature option should be used when the allowable stress values in Table K-1 are in boldface (K304.1.2(b)).

CALCULATOR : ASME B31.3 Table K-1 High Pressure Pipe Wall Thickness From Temperature Nickel Alloy Pipe And Tube [PLUS] ±

Calculate pipe wall thickness from temperature for nickel alloy pipe and tube (ASME B31.3 Section K304.1 And Table K-1). The allowable stress values for nickel alloy (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.
