API 650 larger diameter tanks tank-bottom reinforcing plate

Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API 650 larger diameter tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.

Before welding the API 650 larger diameter tanks, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API 650 larger diameter tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API 650 larger diameter tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
