A516 Gr 380 plates API Std 650 ground supported tanks

Personnel organization before the construction of the API Std 650 ground supported tanks:
The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API Std 650 ground supported tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.

Material for the outer tank API Std 650 ground supported tanks and for the roof that contains the vaporized liquefied gas but is primarily subjected to atmospheric temperatures may conform to one of the following:
a)Table 4-1 for design metal temperatures down to –35°F (lowest 1-day mean ambient temperature of–35°F) without impact test unless they are required by Table 4-1 or by the Purchaser.
b)Table R-3 for design metal temperatures down to –60°F without impact tests unless they are required by Table R-4 or by the Purchaser.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 ground supported 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 Std 650 ground supported 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.
