API 650 aboveground petroleum storage tanks tank shell

In order to ensure the safety of the vertical storage tank, API 650 aboveground petroleum storage tanks, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API 650 aboveground petroleum storage tanks, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API 650 aboveground petroleum storage tanks plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.The API 650 is widely used for tanks designed to withstand low internal pressures, for the API 650 aboveground petroleum storage tanks storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.Keep in mind your mission and never forget your mission."
