EN 10025 grade S275 plates API 650 special tank

Design of Compression-ring Regions
In this project, a cylindrical tank 30 ft in diameter is designed for an internal pressure of 5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade A steel for thicknesses of 1/2 in. and less. The top course of the butt- welded cylindrical sidewall is 1/4 in. thick, including a 1/16 in. corrosion allowance. The tank API 650 special tank roof is a butt-welded spherical dome with an internal radius of 30 ft and a thickness of 1/4 in., including a 1/16 in. corrosion allowance. The maximum design liquid level is 6 in. below the plane of the juncture of the roof and sidewall.

Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API 650 special tank can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).

Tunisia cutomer purchased around 1500 tons 304L,310S stainless steel plate from us and make tanks in August, 2017. The company was skilled in the design and manufacture of stainless steel tanks, API 650 special tank processing systems and equipment for the food, dairy, beverage, chemical, pharmaceutical, biotechnology, and pure water industries. They also sent the inspection team come our company and visited our production line. After using our stainless steel plate, the customer was very satisfied with our products.

During heavy rain, closely observe the change of the water level in the storage area of the API 650 special tank. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API 650 special tank area to avoid lightning accidents. Observe the groundwater level of the API 650 special tank area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API 650 special tank from leaking and rusting due to untimely drainage.
