48m diameter API Std 650 open-top tanks

The design metal temperature of API Std 650 open-top tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.

Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API Std 650 open-top tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).

We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 open-top tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API Std 650 open-top tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 open-top tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API Std 650 open-top tanks from leaking and rusting due to untimely drainage.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
