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 Std 650 stainless steel 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.
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 Std 650 stainless steel 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.

}How to effectively increase the service life of API Std 650 stainless steel storage tanks oil tanks? It is necessary to check and inspect the oil tank regularly in the process of use, and do a good job in the maintenance and cleaning of the oil tank. The oil tank should be inspected every 6 years. With the increase of service life, the inspection interval should be shortened. Daily maintenance and cleaning of the API Std 650 stainless steel storage tanks can prolong the service life of the oil tank. The maintenance of the API Std 650 stainless steel storage tanks mainly includes the anti-corrosion inspection of the oil tank, the maintenance of the accessories, and the cleaning of the sediment in the tank.
Both parties shall confirm the API Std 650 stainless steel storage tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API Std 650 stainless steel storage tanks steel plant.
