220ft diameter API 650 aboveground oil storage tanks

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality API 650 aboveground oil storage tanks, efficient and fast services. Facing the future, adhere to independent innovation.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 oil 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.Fixed roof API 650 oil storage tank includes inner floating roof tank, which API 650 aboveground oil storage tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API 650 aboveground oil storage tanks storage tank".Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! And sincerely hope to establish a long-term cooperative relationship with them, mutual benefit and common development.Due to the volatility of oil products, the volatile consumption of oil products is inevitable in the storage process of large oil storage tanks such as API 650 aboveground oil storage tanks. The volatilization of oil causes economic losses and pollution to the environment. Especially in the open air environment, large-scale oil storage tanks in the petrochemical industry will continue to accumulate energy when exposed to the sun, causing their surface and interior to heat up rapidly, causing sun overheating, and accelerating the volatilization of oil. How to effectively reduce the volatile consumption of large oil storage tanks?
