Steel plate for bottoms of API 650 closed top welded storage tanks
The reticulated API 650 closed top welded storage tanks shell API 650 storage tank is an important large-span space structure with high safety. Generally, the large-scale API 650 storage tank with a diameter of 21-60 meters or a volume of more than 20000 cubic meters should adopt the reticulated shell technology, which has been widely promoted and adopted in the world and China's petrochemical industry for more than 30 years.
Inspection of API 650 closed top welded storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 closed top welded storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 closed top welded storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 closed top welded storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
Above the water level, all API 650 closed top welded storage tanks welded joints, all welds around openings, and all piping joints against which the pneumatic pressure is acting shall be checked with a solution film. A visual inspection may be substituted for the solution-film inspection if the welded joint has previously been checked with a vacuum box. The solution-film inspection shall still be made, above the water level, on all welds around openings, all piping joints, and the compression ring welds, including the attachment to the roof and shell.
Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API 650 closed top welded storage tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API 650 closed top welded storage tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.
