single-deck pontoon-type floating roof API standard 650 tanks

,API standard 650 tanks. weld tightness test: remove dirt from the API standard 650 tanks weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.refrigerated tanks secondary components are those whose failure would not result in leakage of the liquid being stored. Secondary components also include those API standard 650 tanks components that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature vapors and have a combined tensile and primary bending stress under design conditions that does not exceed 6000 lbf/in.2. Secondary components that could be designed within this reduced stress are roof plates, including roof manways and nozzles with their reinforcement, roof-supporting structural members, and shell stiffeners.API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API standard 650 tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.Aspire to technological innovation and pursue first-class quality steel API standard 650 tanks products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies.
