API Std 650 welded steel oil storage tanks shell nozzles and flanges
The impact tests for API 620 welded storage tanks used pipe (including structural members made of pipe), bolting, and forgings, shall be in accordance with ASTM specifications ASTM A333 (seamless only) pipe, ASTM A36 Mod 1 plate, ASTM A131 Grades CS, D, and E steel plate, ASTM A633 Grade A CSA G40.21 Grades 38WT, 44WT and 50WT high-strength low-alloy structural steel plate, ASTM A350 carbon and low alloy steel forgings, and ASTM A320 Grade L7 bolts.
The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API Std 650 welded steel oil storage tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API Std 650 welded steel oil storage tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
}According to the structure type of floating roof, floating roof API Std 650 welded steel oil storage tanks can be divided into internal floating roof tank and external floating roof storage tank. The internal floating roof tank is a floating roof tank with tank roof. The top is the combination of dome roof and floating roof, the external is dome roof, and the internal is floating roof. There is no vault on the top of the External floating roof tank, only a top plate floating with the storage liquid. The common feature of the inner floating roof tank and the outer floating roof tank is that both of them can reduce the evaporation loss of the storage liquid.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality API Std 650 welded steel oil storage tanks products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
