API Std 650 tanks supported cone roofs
Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API Std 650 tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API Std 650 tanks Tanks must be above ground with a closed or open top.
The thickness of the API Std 650 tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in. (2.5)(0.375) + 0.75 = 1.69 in.
In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.
The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on.

As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel API Std 650 tanks products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
