API Std 650 welded steel storage tanks allowable stresses
Temperature Range: The provisions in this appendix are considered suitable for API Std 650 welded steel storage tanks design metal temperatures from + 40°F to –60°F, inclusive. In general, refrigerated tank primary components include those components whose failure would result in leakage of the liquid being stored, those exposed to the refrigerated temperature, and those subject to thermal shock. Further definitions of such components are provided in API Standard 620 tank R.1.4.2 and R.1.4.3.
Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API Std 650 welded steel storage tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 0.1 mm is created between the internal and external layers. Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environment.
Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API Std 650 welded steel storage tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
}In the actual welding of API Std 650 welded steel storage tanks, operators will use more arc-shaped plates for tailor-welding to better adapt to the larger volume of oil storage tanks. In order to effectively control the deformation of the welding seam of the API Std 650 welded steel storage tanks, a scientific and accurate prefabricated bottom plate is required. In the process of prefabricating the bottom plate of the oil storage tank, it is necessary to strictly follow the technical requirements for the construction of the oil storage tank. At the same time, it is also necessary to clarify the external dimensions according to its actual manufacturing standards so that it has sufficient shrinkage.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
