Hydrostatic test of API Std 650 welded steel oil storage tanks

Design of a Double-wall Tank
The outer bottom, shell, and roof of a double-wall tank shall enclose an insulating space around the bottom, shell, and roof or insulation deck of the inner tank that contains the stored liquid. The annular space shall be maintained at a low positive pressure, which necessitates that the enclosure be vapor-tight. The Purchaser shall specify the design metal temperature and pressure of the inner tank and may specify the design temperature and pressure of the outer tank API Std 650 welded steel oil storage tanks. The Purchaser shall state the specific gravity of the content to be stored, roof live loads, wind load, earthquake load where applicable, and corrosion allowance, if any.

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 Std 650 welded steel oil 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 Std 650 welded steel oil storage tanks test.

Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API Std 650 welded steel oil storage tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.

API Std 650 welded steel oil storage tanks Drain hole: The drain hole is generally installed at the bottom of the oil tank, used to remove sludge when cleaning the oil tank, and usually used to drain the sewage in the tank. API Std 650 welded steel oil storage tanks Safety valve: The role of the safety valve is to play a safety role when the breathing valve fails during the operation of the oil tank. Its working pressure is slightly higher than the pressure of the breathing valve, which can prevent the tank from being damaged due to the high positive or negative pressure in the tank. The safety valve is usually installed in the middle of the API Std 650 welded steel oil storage tanks top.
