API Std 650 low-alloy steel tanks emergency roof drains

Steel Storage Welded Tank Certification
A certificate shall be supplied for each tank. This practice is intended to simplify keeping the records of future inspection in separate files for convenience. When a group of crude oil storage tanks is being constructed on one order and in one general location some specific form of reporting other than a API Std 650 low-alloy steel tanks Manufacturer’s report may be preferred by both parties. It would seem desirable that the details on each contract be settled when the purchase order is placed; if they are not covered in the proposal, then they shall be given as information in the inquiry.

API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API Std 650 low-alloy steel tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

API Std 650 low-alloy steel tanks foam generator is a fire extinguishing device fixed on the oil tank. One end of the foam generator is connected to the foam pipeline, and one end is flanged on the top layer of the API Std 650 low-alloy steel tanks wall. Fire extinguishing foam flows through the air intake entrance of the fire foam chamber, inhaling a large amount of air to form foam, and breaking through the insulating glass into the tank (glass thickness is not greater than 2mm), so as to achieve the purpose of fire fighting.
