ASTM A216 grade WCB external floating roofs API Std 650 stainless and carbon steel tank

API Std 650 stainless and carbon steel tank Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API Std 650 stainless and carbon steel tank storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.

With the continuous development of large-scale oil storage tanks, the foundation of API Std 650 stainless and carbon steel tank has also continued to grow. Among them, API Std 650 stainless and carbon steel tank vertical oil tanks are storage tanks commonly used to store crude oil, diesel, gasoline and other oil materials. This type of storage tank is set up as a cylindrical shape. The bottom of the tank is a circular flat bottom plate, and the load surface of the oil tank is basically horizontal, which can generally be regarded as a uniform load, and has greater flexibility.
