api 620 tank manufacturers, 12MnNiVR steel plate is for large oil storage tank. Compared with SPV490Q in JIS G3115, the crack sensitivity coefficient PCM is lower, which is more conducive to steel plate welding; the sampling direction of impact test is changed from longitudinal to transverse, the impact temperature is changed from - 10℃ to - 15℃ or lower, and the impact energy is increased.

Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the api 620 tank manufacturers used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.

Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal api 620 tank manufacturers floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.

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 manufacturers 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.
