EN 10025 S355 plates API standard 650 carbon and low-alloy steel tanks

According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API standard 650 carbon and low-alloy steel tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API standard 650 carbon and low-alloy steel tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API standard 650 carbon and low-alloy steel tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

All oil tanks have service life. Due to the pressure of the oil stored on the tank and the corrosion of the oil and external environment on the tank, the oil storage tank will gradually become thin or crack after a long time. Due to the different materials and environment of API standard 650 carbon and low-alloy steel tanks, the consumption of API standard 650 carbon and low-alloy steel tanks is different, so it should be taken into account when evaluating the remaining service life of API standard 650 carbon and low-alloy steel tanks.

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization. As a company specializing in logistics, third-party logistics companies have a wealth of experts who specialize in logistics operations, which is conducive to ensuring the professional production of the company, reducing costs, and improving logistics level of the company. Both the customers and the company benefit from the logystics mode.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
