What is Stress Relieving? - Definition from Corrosionpedia

petroleum storage tanks Thermal Stress Relief#0183;A stress relief operation is typically used to remove internal (residual) stresses that have accumulated in the material.These stresses can cause loss of tolerance,cracking and distortion,and contribute to in-service failures.For these reasons,stressWelding after PWHT for API 650 tanks petroleum storage tanks Thermal Stress Relief#0183;API 650 tank shell plates welded with nozzles re pads require Stress relieving.After SR,fixtures removed and the shell plates were minor touch up welding carried out on fixture removal areas.Plate material is ASTM A573 Gr 70,medium is gas oil/fuel oil; no service requirement for PWHT or Impact requirement for shell plates.Thermal stress relief in nozzle welds - Storage tank Greetings,we have certain doubts about the stress relief in the welds of nozzle in the shell of an AST,in API 650 2013 in 5.7.4,states in 5.7.4.2 and 5.7.4.3 that the connection shall be prefabricated into the shell plate or thickened insert plate,and the prefabricated assembly shall be thermally stress-relieved within a temperature range of 600 petroleum storage tanks Thermal Stress Relief#176;C to 650 petroleum storage tanks Thermal Stress Relief#176;C (1100 petroleum storage tanks Thermal Stress Relief#176;F to 1200 petroleum storage tanks Thermal Stress Relief#176;F) for 1
