API standard 650 liquid-storage tanks calculated failure pressure

The company has been engaged in the design, construction and installation of foreign API 650 standard API standard 650 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 liquid-storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.

In order to ensure the safety of the vertical storage tank, API standard 650 liquid-storage tanks, the supplier should inspect the tank carefully before delivery. The failure of the tank body is mainly due to the weld and crack of the product. The inspection of API standard 650 liquid-storage tanks, vertical storage tank weld and microcrack is mainly to inspect the appearance forming quality of weld. The inspection contents include weld leg height, undercut, welding deformation, weld bead, arc pit, weld straightness, etc., as well as the internal quality of weld, such as slag inclusion, porosity, incomplete penetration, crack, incomplete fusion, etc.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API standard 650 liquid-storage tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API standard 650 liquid-storage tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API standard 650 liquid-storage tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

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 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 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.
