API 650 insulated tanks attachments
The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API 650 insulated tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API 650 insulated tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
For the welding of API 650 insulated tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API 650 insulated tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.
The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on. At the same time, the system can also be used to educate and train employees, send blessings to employees on their birthdays or during Chinese New Year holidays, so that employees can feel the practice of corporate culture, the warmth of the enterprise, and enhance the sense of belonging and recognition of the enterprise.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, API 650 insulated tanks , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.
Our company will accept the product quality objection registration record, pass it to the API 650 insulated tanks production unit and relevant departments, and timely coordinate the supervision of product API 650 insulated tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
