API standard 650 ground supported liquid storage tanks top and intermediate stiffening rings
The company has been engaged in the design, construction and installation of foreign API 650 standard API standard 650 ground supported liquid storage tanks storage tanks for a long time. It has the international qualification of ASME welding technology, has the design ability of API 650 oil tanks and API 650 storage tanks, and has pressure vessel design and manufacturing license and GC pressure pipeline installation license. Certificate, API standard 650 ground supported liquid storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.
Crack treatment of API standard 650 ground supported liquid storage tanks weld area: find out the crack tip with ray or ultrasonic flaw detection, drill cut-off holes at both ends of the crack with the cut-off method, the hole depth is slightly greater than the crack depth, or groove (crack stop groove) is made by angle grinder at both ends of the crack, shovel and grind the whole crack, and grind it into a suitable groove; use radiographic inspection and dye detection to verify that the crack has been completely excavated, and finally repair welding.
The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API standard 650 ground supported liquid storage tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.
Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical API standard 650 ground supported liquid storage tanks personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and API standard 650 ground supported liquid storage tanks after-sales service of the project.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API standard 650 ground supported liquid storage tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API standard 650 ground supported liquid storage tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
