API 650 liquid-storage tanks reinforcement of weld

Application scope of API 650 petroleum storage tank:
1. API 650 liquid-storage tanks Working pressure: atmospheric storage tank;
2. API 650 petroleum storage tank working temperature: -30℃～150℃;
3. API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;
4. API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic meters.

Service Conditions and Hydrogen-induced Cracking
When the service conditions might include the presence of hydrogen sulfide or other conditions that may promote hydrogen-induced cracking effects, particularly near the bottom of the API 650 liquid-storage tanks shell at the shell-to-bottom connections, care shall be taken to ensure that the materials and details of construction of the tank are adequate to resist hydrogen- induced cracking. The Purchaser shall consider restricting the sulphur content of the material to be stored through thickness testing of the steel, laboratory surveillance tests, and the use of internal tank coatings to reduce the possibility of hydrogen-induced cracking.

For the welding of API 650 liquid-storage tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API 650 liquid-storage tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.

The API 650 liquid-storage tanks company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest API 650 liquid-storage tanks teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.

The company's logistics adopts the method of cooperation with logistics companies. As a third-party logistics company is engaged in the operation of multiple logistics projects, it can integrate various logistics resources, making the logistics operation cost relatively low and the logistics operations more efficient. Thus we can provide more professional logistics services, while also focusing on our core business of steel materials.

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 650 liquid-storage 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.
