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

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our api 620 tank primary components products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

Welding inspection of bottom plate of api 620 tank primary components, vertical oil tank: During the fabrication and installation of api 620 tank primary components, the bottom edge plate is welded first. According to the requirements of the technical standard, penetrant inspection is required for the weld of edge plate at the bottom of api 620 tank primary components, that is, penetrant testing is required for each weld bead priming, filling and capping. In the process of testing, if any defect is found, it shall be repaired immediately.
