May 28, 2018 · Circle Valve Technologies offers three series of safety relief valves that meet this ASME code, the M5100 series ASME, D500 Series ASME and the Rockwood Swendeman relief valve. These valves are unique, in that they must meet a specific flow requirement at a specific set pressure.
ASME B31.3 Design for Sustained and Occasional Loads The ASME B31.3 Code is consistent with the structural codes in the treatment of occasional loads. The sum of all longitudinal stress, including both sustained and occasional loads, is limited to 1.33 times the basic allowable stress. This differs from the Pressure Vessel Code, which uses a factor of 1.2.

Avoiding Production Test Coupon (PTC) Failures in ASME Sec Jun 01, 2018 · Production coupon testing as per ASME Sec VIII Div 1 is generally limited to Charpy impact test. thermally treated to simulate a stress relief heat treatment or a
Code Requirements For Thermal Expansion Relief Val May 27, 2004 · Since you mention ASME, I assume you mean the mechanical design:the metallurgy, the orifice type & size, the connections, the stress analysis, etc. Additionally, the employment of a thermal relief device falls under a common-sense safety engineering decision - not a "code".
The ASME VIII-1 code equations used for Cylinders and Hemi heads are easily derived. The ½ thick cylinder ends up with a stress equal to the code design stress limit of 20,000 psi. When calculated by FEA using a Tresca formulation, the stress is 20,484 psi Tresca or Stress Intensity P1-P3.
Heat Treatment - What Is It? - National Board of Boiler Preheating of the weldment area achieves better weld penetration and slows the cooling process, thus allowing added relief of stresses and reduced hardening of the materials. The ASME Code sections take cognizance of the foregoing, in some cases allowing exemption from postweld stress relieving PROVIDED preheating of a specified temperature is
Hydrostatic Pressure Tests ASME Pressure Vessels As per ASME Section VIII-1, UG-99, the pressure vessels designed for internal pressure shall be subjected to a hydrostatic test pressure which at every point in the vessel is at least equal to 1.3 times the MAWP multiplied by the lowest ratio for the materials of which the vessel is constructed of the stress value S for the test temperature on
Jun 26, 2008 · It is also not a replacement for thermal stress relief (TSR) if it is specified by the code. As mentioned by Jon, it is not addressed by ASME, so it is not allowed to be substituted. However, since it is not addressed, then VSR is not prohibited by the code either, but it can't take the place of TSR.
What is Stress Relieving and Why We Need It WELDING Stress relieving is a form of post weld heat treatment. In stress relieving we heat a material to a specific temperature; hold it at this temperature for a specified amount of time in order to reduce or eliminate residual stresses; and then cool it at a slow enough rate to prevent these stresses from redeveloping. 
Why Perform UG-99 Hydrotest Stress Calculations? ASME Code paragraph UG-99 requires that all vessels undergo hydrostatic (or pneumatic) testing before Code stamping. As this test provides mechanical stress relief it may be thought of as the final step in the fabrication process. The UG-99 hydrostatic test is an effective way to screen for design, material and fabrication deficiencies as well
