API 650 self-anchored flat-bottom tanks automatic welding

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API 650 self-anchored flat-bottom tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

API 650 storage tank, double-layer oil tank environmental protection advantages: ordinary single-layer steel API 650 self-anchored flat-bottom tanks oil tank is corroded by underground water and gas and electrolytic corrosion because it is buried underground all year round. The API 650 tank has a double-layer structure with a gap of 0.1 mm. The API 650 self-anchored flat-bottom tanks outer layer of FRP ensures that the leakage will not directly leak into the soil and water source.

Our client purchase more than 900 tons pipe API 650 self-anchored flat-bottom tanks from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.

Inspection of API 650 self-anchored flat-bottom tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 self-anchored flat-bottom tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 self-anchored flat-bottom tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 self-anchored flat-bottom tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
