5456 aluminum rod API 650 self-anchored flat-bottom tanks

Define the welding sequence of API 650 self-anchored flat-bottom tanks bottom plate: the welding sequence of metal vertical storage tank shall be carried out according to the procedure required by the welding scheme. Spot welding shall be consistent with the formal welding requirements, and no spot welding shall be carried out for the weld not welded. Back bar should be added to prevent deformation when welding the full length seam of middle plate, butt joint of edge plate and turtle shell joint.

The design metal temperature of API 650 self-anchored flat-bottom tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API 650 self-anchored flat-bottom tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API 650 self-anchored flat-bottom tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
