API Std 650 flexible liquid storage tanks bottom annular-plate joints
API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 flexible liquid storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.
Before welding the API Std 650 flexible liquid storage 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 Std 650 flexible liquid storage 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.
The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API Std 650 flexible liquid storage tanks shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 flexible liquid storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
