Steel plate and pipe materials for API Std 650 stainless and carbon steel tank

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API Std 650 stainless and carbon steel tank base materials, nickel alloy based materials, aluminum base materials, and weld deposited for the nonferrous (aluminum) materials. Impact tests are not required for austenitic stainless steel welds deposited by all the welding processes for services of –200°F and above. Austenitic stainless steel welds deposited for service below –200°F by all welding processes shall be impact tested in accordance with Q.6.2 except that the required impact values shall be 75% of the values as given in Q.2.2.2, Item c.The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API Std 650 stainless and carbon steel tank operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.FANALCA is the biggest motorcycle factory in Columbia. Meanwhile, it is the only distributor in Colombia for Japanese Honda. We began to cooperate with each other since 2017. We supply SAPH370, SAPH440 and so on automobile steel coils to them. As our products quality is proved to be satisfied during their production, they have been one of our stable customers, and give repeat orders about automobile steel every year.When the day light gradually decreases, the temperature of oil in the API Std 650 stainless and carbon steel tank will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 stainless and carbon steel tank will also decrease. When the pressure in the API Std 650 stainless and carbon steel tank is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 stainless and carbon steel tank through the open vacuum valve, which is the "suction" process of the oil tank.The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
