API standard 650 SUG I tanks shop inspection

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API standard 650 SUG I tanks aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

Large Low-Pressure Tanks Corrosion Allowance
In cases in which the rate of corrosion is closely predictable, additional metal thickness over and above that required for the initial operating conditions shall be provided and shall be at least equal to the expected corrosion loss during the desired life of the tank.
When corrosion effects are indeterminate before the tank is designed (although they are known to be inherent to some degree in the service for which the tank is to be used), and when corrosion is incidental, localized, or variable in rate and extent, the best judgement of the API standard 650 SUG I tanks designer must be exercised in establishing reasonable maximum excess tank wall thicknesses. For all tanks that come under this classification, a minimum corrosion allowance of 1/16 in. shall be provided.

When the API standard 650 SUG I tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API standard 650 SUG I tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.

We have a high-quality elite team, with a wealth of steel products resources and business experience. The company has established a perfect career development channel to provide all employees with broad job development opportunities, clear career planning, so that the potential can be fully explored, talent can be fully exploited, and a platform for employees to realize the value of life can be built, so as to realize the common growth and development with employees in the long-term development of the company.

Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores API standard 650 SUG I tanks ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
