API 650 ground-supported liquid storage tanks intermediate wind girders

For open top and fixed roof API 650 tanks, the net working capacity is the liquid volume contained between the minimum operating level (top of API 650 tanks API 650 ground-supported liquid storage tanks outlet connection) and the maximum operating level [limited to the bottom of overflow connection, 75 mm below foam chamber connection, or 150 mm below rim, whichever is greater.

The cost of mechanical cleaning for vertical storage tank, API 650 ground-supported liquid storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API 650 ground-supported liquid storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API 650 ground-supported liquid storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.

Charpy V-notch specimens shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or from duplicate test plates.
Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

Steel transportation because of the special material of API 650 ground-supported liquid storage tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
