ASME B31 - Pressure Piping - Engineering ToolBoxB31 Code for pressure piping, developed by American Society of Mechanical Engineers - ASME, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping. ASME B31 was earlier known as ANSI B31. B31.1 allowable stress for piping materials as per asme b31 3 Grinding ASME B31.3 Limitations on Flanges - ASME | Caesar IIASME B31.3 Limitations on Flanges. Most flanges in ASME B31.3 piping systems are in accordance with the following listed standards: ASME B16.5, Pipe Flanges and Flanged Fittings. ASME B16.24, Cast Copper Alloy Pipe Flanges and Flanged Fittings: Classes 150, 300, 600, ASME B 16.36, Orifice Flanges, Classes 300, 600, 900, 1500, and 2500.

ASME B31.3-2012 (Revision of ASME B31.3-2010) Process Piping ASME Code for Pressure Piping, B31 AN AMERICAN NATIONAL STANDARD Three Park Avenue New York, NY 10016 USA ASME B31G Level 2 Calculator - Pipeng ToolboxThe allowable local pressure is calculated including external pressure (use the external pressure = 0 for dry pipelines). The allowable reference pressure is calculated from the local allowable pressure, and the relative elevation. ASME B31G is suitable for blunt defects of all types, including corrosion, mechanical damage and grinding repairs etc. ASME Section VIII - Cyclic Loads - ASME (mechanical) Code allowable stress for piping materials as per asme b31 3 GrindingTo replace it, I want to apply a lower allowable stress based on fatigue which would lead to a thicker shell, but I cannot find S-N data (fatigue data) for Alloy 825 material to determine my new allowables allowable stress for piping materials as per asme b31 3 Grindingso I was wondering if Section VIII just adds a reduction factor allowable stress for piping materials as per asme b31 3 Grinding.like ASME B31.3 Process Piping code. ASME B31.3 uses a deduction factor allowable stress for piping materials as per asme b31 3 Grinding
ASME reviews test requirements for pipes, fittings, flanges
Two relevant industry codes, ASME VIII Div. I and ASME B31.3, consider carbon steelsany ferrous material having 0.29 to 0.54% carbon and 0.60 to 1.65% manganeseto be ductile enough for service in hot climates, mild zones, and areas in which the temperature gets as low as -20 degrees F. Acceptable Design for Unequal Wall ThicknessThe surface of the weld can also be tapered to accommodate differing thickness. This taper should not exceed 30. It may be necessary to deposit weld metal to assure that these limits are not violated. Below some tables with acceptable design for unequal wall thicknesses ASME B31.8. (1) No minimum when materials joined have equal specified allowable stress for piping materials as per asme b31 3 Grinding Allowable Stress for Piping Materials as per ASME B31.3Section 302.3.2 (d) of ASME B31.3 provides the basis of design stress or allowable stress for piping materials. As per this section, the basic allowable stress values at temperature for materials other than bolting materials, cast iron, and malleable iron shall not exceed the lowest of the following for temperatures below the creep range:
By medicinehawk01 Date 09-29-2008 02:18. Arc burn or arc strikes are said to cause a stress riser which in time could lead to a failure in the HAZ (or weld) according to ASME B.31.1 (or B.31.3) I forget. It really depends on how deep (IF at all) this defect is. B31.3 Interpretation RequestProbably you can find the answer to your questions in B31.3 piping welds acceptance criteria. By js55 Date 10-08-2009 14:07 Before we get too carried away with the stress riser idea lets keep in mind that a weld itself is a stress riser. Comparing materials for high-temperature steam pipingAllowable stress, per ASME B31.1 code, is the same for both P91 and X20 at 540 degrees C. The allowable stress is increasingly higher for P91 at higher temperatures. Therefore, any advantages of X20 based on its lower thickness requirement can be obtained by using P91 at 540 degrees C and higher.
