Sliding friction resistance of API 650 liquid storage tanks
The company has been engaged in the design, construction and installation of foreign API 650 standard API 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 650 liquid storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.
Inspection of API 650 liquid storage tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 liquid storage tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 liquid storage tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 liquid storage tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
The density of the liquid API 620 large welded, low pressure storage tanks stored shall be its maximum density within the range of design temperatures, but no less than 36 lbf/ft3. The maximum allowable tensile stress shall be taken from Table 5-1 or Table Q-3. For the maximum allowable stresses for design loading combined with wind or earthquake loads, see API Standard 620 5.5.6 for carbon steel and Q.3.3.5 for stainless steel and aluminum.
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.
The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.
