How to test roof seams of API 650 insulated tanks

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 insulated 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.

Prevent the storage liquid from impacting the inner wall of the API 650 petroleum storage tank or increase the internal pressure, reduce the corrosion of the tank top and the tank wall, and extend the service life of the API 650 insulated tanks storage tank.

We exported 352 tons SA387GR12CL2 steel plates to Vietnam. The Vietnam customer needed the SA387GR12CL2 steel plates for their tank fabrication project urgently. We are world class steel materials supplier and exporter. Other than regular fresh production, we also keep huge stocks, so as to meet urgent demands of our customers. For the 352 tons SA387GR12CL2 steel API 650 insulated tanks plates, we collected from our warehouse and it only took us 3 days to arrange delivery. The customer was really impressed by our rapid shipping and spoke highly of our SA387GR12CL2 steel plates quality after use.

The preparatory work before the construction of the API 650 insulated tanks is directly related to the quality assurance, project progress, construction safety and other aspects of the entire oil tank project. Therefore, the preparation work before the API 650 insulated tanks construction should be paid attention to and planned. Before API 650 insulated tanks construction, you need to prepare conventional machinery, materials, and facilities, as well as the quality control of the project, such as the installation method of the API 650 insulated tanks, the welding method of the steel plate, and the inspection of the tank material. In addition, there is the most important item, construction safety protection.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API 650 insulated tanks sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
