Thread Content

The assembly of the first 8,800-cubic-meter spherical tank for the first phase of the Angola Lobito refinery project officially began on November 7. The assembly of the first 8,800-cubic-meter liquefied gas spherical tank for the first phase of the Angola Lobito refinery project under the Northwest Branch started on that date. This tank is one of the storage tanks with the largest volume and highest technical requirements in the Angola project; the assembly of this spherical tank marks a new phase in the project’s development, where construction has moved beyond the initial building works to a stage where equipment installation and system testing proceed simultaneously. The first spherical tank was lifted in sections and assembled on-site. During the lifting operation, a 300-ton truck crane was put into use after a third party had conducted tests to verify its safety performance; the first section of the tank was lifted smoothly and placed in position accurately. After welding, the spherical tank underwent TOUFT ultrasonic testing as well as phased array testing to ensure the quality of the welds and the structural integrity of the tank.
