The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, API standard 650 ground supported tanks and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 ground supported tanks is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 ground supported tanks should be inspected after the completion of construction, and the detection methods of different structure positions are different. Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld. Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency.

Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API standard 650 ground supported tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.
