API 650 unanchored flat-bottom tank gauge wells

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API 650 unanchored flat-bottom tank service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API 650 unanchored flat-bottom tank plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.Before the start of erection, inspect each API 650 tank foundation to ensure that it is level and acceptable to receive Work. Remove temporary erection attachments welded to the interior or exterior of the API 650 unanchored flat-bottom tank shell or to the bottom by arc gouging, and grind weld area smooth.The work concept attaches importance to talents, creates a high-income and high-standard employment mode and work mode, actively advocates all kinds of talents to inspire each other, respect each other, unite and act together, cultivates employees' corporate interests above all else, is tolerant and enterprising, learns correct ways of doing things, improves employees' Professional quality, encourages and urges employees to make continuous progress, Continuously realize self value and grow together with the enterprise.During the use of API 650 unanchored flat-bottom tank, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API 650 unanchored flat-bottom tank must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.
