ISO 630 Gr E355 plates API standard 650 aboveground petroleum storage tanks

Low-pressure storage tanks for Liquefied Hydrocarbon Gases
API standard 650 aboveground petroleum storage tanks Primary Components: In general, primary components include those components that may be stressed to a significant level, those whose failure would permit leakage of the liquid being stored, those exposed to a refrigerated temperature between –60°F and –270°F, and those that are subject to thermal shock. The primary components shall include, but will not be limited to, the following parts of a single-wall tank or of the inner tank in a double-wall tank: shell plates; bottom plates; roof plates; knuckle plates; compression rings; shell stiffeners; and manways and nozzles including reinforcement, shell anchors, pipe, tubing, forgings, and bolting.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 aboveground petroleum storage 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 aboveground petroleum storage tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.Compared with the external floating roof API standard 650 aboveground petroleum storage tanks, the internal floating roof API standard 650 aboveground petroleum storage tanks has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the External floating roof tank.With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel API standard 650 aboveground petroleum storage tanks product quality.
