21m diameter API standard 650 welded storage tanks
BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API standard 650 welded storage tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.
Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 welded storage tanks is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 welded storage 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.
API standard 650 welded storage tanks Visual InspectionUpon completion of all the foregoing tests, the pressure in the tank shall be released and a thorough visual inspection shall be made of both the inside and outside of the tank, giving particular attention to all internal ties, braces, trusses, and their attachments to the walls of the tank. Anchors shall be checked for snug tightness and adjusted if required. Anchor threads shall be fouled by peening or tack welding to prevent loosening. In lieu of thread fouling, double nuts may be used.Rate of Water Filling and Water TemperatureThe rate at which water is introduced into a tank for a hydrostatic test shall not exceed 3 ft of depth per hour. The foundation, venting equipment, or other conditions may limit the water filling to a lower rate. Pressure shall not be applied above the surface of the water before the tank and its contents are at about the same temperature.
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API standard 650 welded storage tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API standard 650 welded storage tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization.
