API 650 stainless and carbon steel tank foundations for elevated temperature service

API 650 is an American standard for welding flat bottom vertical storage tanks. This API 650 stainless and carbon steel tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API 650 stainless and carbon steel tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

Inspection of Butt-welds in Piping
Butt-welds in piping and in API 650 stainless and carbon steel tank pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.

According to the standard of head of API 650 stainless and carbon steel tank, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API 650 stainless and carbon steel tank head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.

Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.

Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the API 650 stainless and carbon steel tank steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the API 650 stainless and carbon steel tank steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the API 650 stainless and carbon steel tank steel sheet on the truck Good luck.
