butt-welded-spherical-dome tank, 12MnNiVR steel plate is for large oil storage tank. Compared with SPV490Q in JIS G3115, the crack sensitivity coefficient PCM is lower, which is more conducive to steel plate welding; the sampling direction of impact test is changed from longitudinal to transverse, the impact temperature is changed from - 10℃ to - 15℃ or lower, and the impact energy is increased.

Combination of Design Loads
The inner tank butt-welded-spherical-dome tank shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

The reticulated butt-welded-spherical-dome tank shell API 650 storage tank is an important large-span space structure with high safety. Generally, the large-scale API 650 storage tank with a diameter of 21-60 meters or a volume of more than 20000 cubic meters should adopt the reticulated shell technology, which has been widely promoted and adopted in the world and China's petrochemical industry for more than 30 years.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, butt-welded-spherical-dome tank A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295, SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the butt-welded-spherical-dome tank steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.
