API Spec 5L pipe API standard 650 carbon steel tank
Service Conditions and Hydrogen-induced CrackingWhen 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 standard 650 carbon steel tank 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.
The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API standard 650 carbon steel tank is permitted when additional requirements are met.
In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate API standard 650 carbon steel tank for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 API standard 650 carbon steel tank and priming gray oxide primer, and arrange shipment in time.
