Joint Efficiency for a lap welded roof - Storage tank

Feb 05,2010 aboveground welded storage tanks Welded Joint Efficiency#0183;I am currently reviewing the design of an API 650 tank built in accordance with App F.D = 86.5' Design pressure = 0.5psi Is it the intent of App F 7.3 that the roof plate on a lap welded should be designed with a joint efficiency of 0.35 as per API 620?Joint Efficiency Pressure Vessel EngineeringJoint efficiency is a factor required in all head and shell calculations that accounts for how closely a finished weld joint approximates the quality of the seamless parent material.Without further inspection it is assumed the welded joint is weaker than the material around it due to potential defects such as porosity,slag inclusions,and others.Joint Efficiency Pressure Vessel EngineeringJoint efficiency is a factor required in all head and shell calculations that accounts for how closely a finished weld joint approximates the quality of the seamless parent material.Without further inspection it is assumed the welded joint is weaker than the material around it due to potential defects such as porosity,slag inclusions,and others.
