API Std 650 welded storage tanks weld size
Under the same sealing effect, the internal API Std 650 welded storage tanks floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 welded storage tanks external floating roof tank.
The head of API Std 650 welded storage tanks etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API Std 650 welded storage tanks. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.
The density of the liquid API 620 large welded, low pressure storage tanks stored shall be its maximum density within the range of design temperatures, but no less than 36 lbf/ft3. The maximum allowable tensile stress shall be taken from Table 5-1 or Table Q-3. For the maximum allowable stresses for design loading combined with wind or earthquake loads, see API Standard 620 5.5.6 for carbon steel and Q.3.3.5 for stainless steel and aluminum.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
