API 650 mechanically-anchored flat-bottom tanks seismic use group iii
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API 650 mechanically-anchored flat-bottom tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
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 mechanically-anchored flat-bottom 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.
In order to ensure the safety of the vertical storage tank, API 650 mechanically-anchored flat-bottom 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 mechanically-anchored flat-bottom 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.
Our company was founded in 2009, and has been committed to steel business since its establishment. Over the years, the company's performance shows a good development trend, with a wide range of customers in the government, domestic and foreign markets.
