We have complete department structure, to make the whole work procedure run smoothly. For every step, we have special person to be in charge and responsible for our customer and update information to the customer in time. So you just need not worry too much to purchase steel materials from our company.Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 ground-supported liquid storage tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.Before pressure test, the main drain hose system of API 650 petroleum storage tank floating roof should be thoroughly flushed. Provide blind flanges, gaskets and bolts required for the API 650 ground-supported liquid storage tanks test (other types of covers are also required if necessary). Covers for maintenance shall be provided in accordance with the interfaces specified by API 650 petroleum storage tanks, and these seals shall remain in place after the test; and for those interfaces that are not provided for maintenance covers, the covers can be removed after the API 650 ground-supported liquid storage tanks test.Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.The construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API 650 ground-supported liquid storage tanks. The API 650 ground-supported liquid storage tanks mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API 650 ground-supported liquid storage tanks has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.
