Technical Inquiries for API Standard 650,Welded Tanks

650-I-37/03 Is it the intent of 3.1.3.5 to limit the maximum lap of a double welded lap joint to 2 in.and a single welded lap joint to 1 in.If not,is there a maximum lap requirement for single welded lap joint bottoms and roofs? Would this constraint,if any,also apply to bottom or roof repair or replacements governed by API 653.No.TECHNICAL CALCULATION AND ESTIMATOR'S MANi.piping above ground ii.pipelines iii.steel structures iv.process equipment v.storage tanks cylindrical and spheroidal vi.welding and flame cutting vii.corrosion protection viii.thermal insulation ix.estimates x.piping above ground estimate points for build-in items xi.weight factors xii.technical calculation manner of datas Storage Tank Welding Procedure - Storage tank engineering Sep 16,2011 ground supported liquid storage tanks single welded lap joint#0183;I would like to ask for some advice on welding sequence on API 650 storage tanks which I know is not covered in the standard.When erecting a storage tank with a crane we have typically fully welded the verticals of one shell course before welding the verticals of the course above and then the horizontals between the 2 courses to allow free movement of the shells due to heat to minimise on

The deck plates of single-deck-type floating roofs for large oil storage tanks are joined by single-welded Full-fillet lap joints.In areas with frequent strong winds,fatigue cracks sometimes Oil Tank Installation - Parkside Oil TanksAlways a tough tank.Welded lap joint the strongest one.Handles on each head for easy handling.Easy to install. Power Flow in fuel oil is a sludge and water dispersant,which prevents waxing and jelling of oil,and inhibits formation of rust in the tank. 50% lighter than a 12-gauge steel tank with a larger storage capacity.
