API standard 650 ground supported flat-bottom tanks NPS 8 sample hatch

The lip seal of floating roof storage tank, API standard 650 ground supported flat-bottom tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API standard 650 ground supported flat-bottom tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.Material for the outer tank API standard 650 ground supported flat-bottom 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.Application scope of API 650 petroleum storage tank:
