A841 Gr B Cl 2 plates API Std 650 cylindrical liquid-storage tank

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API Std 650 cylindrical liquid-storage tank storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.

API Std 650 cylindrical liquid-storage tank Oil measuring hole: The oil measuring hole is used to measure the height, temperature and sampling of the oil stored in the tank, and is installed near the tank top platform. API Std 650 cylindrical liquid-storage tank Fire extinguisher: The fire extinguisher (also known as the flame arrestor) of the oil tank is composed of a fire box, a copper wire mesh and an aluminum partition. It is installed under the breathing valve or safety valve to prevent sparks and air from entering the inside of the tank through the breathing valve or safety valve and causing accidents.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API Std 650 cylindrical liquid-storage 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.

Our quality control department will do inspection for details of the steel materials API Std 650 cylindrical liquid-storage tank before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
