API Std 650 SUG I tanks liquid penetrant examination

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 SUG I 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 SUG I tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.

Welding inspection of bottom plate of API Std 650 SUG I tanks, vertical oil tank: During the fabrication and installation of API Std 650 SUG I tanks, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of API Std 650 SUG I tanks, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately. After the repair, the surface coloring penetrant test shall be conducted again until the test result is qualified.

Design of Compression-ring Regions
In this project, a cylindrical tank 30 ft in diameter is designed for an internal pressure of 5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade A steel for thicknesses of 1/2 in. and less. The top course of the butt- welded cylindrical sidewall is 1/4 in. thick, including a 1/16 in. corrosion allowance. The tank API Std 650 SUG I tanks roof is a butt-welded spherical dome with an internal radius of 30 ft and a thickness of 1/4 in., including a 1/16 in. corrosion allowance. The maximum design liquid level is 6 in. below the plane of the juncture of the roof and sidewall.

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

Management information and high efficiency. Because of the rapid flow of API Std 650 SUG I tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
