API Std 650 ground supported tanks erection requirements
The keyword shell that contains the liquid shall have butt-welded annular bottom plates with a radial width that provides at least 24 in. between the inside of the shell and any lap-welded joint in the remainder of the bottom and at least a 2-in. projection outside the shell. The stated values apply to full-sized specimens. For sub-size specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 large welded, low pressure storage tanks Manufacturer.
Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API Std 650 ground supported tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 0.1 mm is created between the internal and external layers. Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environment.
3500 tons SA387GR5CL1 steel plate to make pressure vessel equipment in Pakistan. The main business of our this client from Pakistan is manufacturing Columns&Towers, Heat Exchanger,Waste Heat Recovery Boiler, Pressure Vessel&Reactors,Tanks, Metering Skid. And we supply API Std 650 ground supported tanks the Mill Certificate, Shipping picture, the marking of steel plate and we help client to do SGS inspection.
Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API Std 650 ground supported tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API Std 650 ground supported tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.
Our company will accept the product quality objection registration record, pass it to the API Std 650 ground supported tanks production unit and relevant departments, and timely coordinate the supervision of product API Std 650 ground supported tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
