Steel pipe materials for API Std 650 partially anchored liquid-storage tanks

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API Std 650 partially anchored liquid-storage tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.

Low-pressure Storage Tanks Fireproofing
Although general fire prevention and fire protection measures are expected to be fully covered by other safety codes, tanks API Std 650 partially anchored liquid-storage tanks constructed according to these rules, which may be subject to fire exposure resulting from any cause, shall have their supports suitably fireproofed.
Special consideration shall be given to provisions for ample drainage facilities for accidental spills or leakage of flammable contents from such tanks or adjacent piping and other equipment if the contents may become ignited.
Subject to special considerations in isolated locations, tanks in which flammable liquid products are stored at temperatures well above their average boiling point shall be suitably fireproofed or otherwise protected.

Prefabrication requirements for API Std 650 partially anchored liquid-storage tanks, large vertical storage tanks:
1. The machined surface of the edge of the steel plate should be smooth, and there should be no defects such as slag inclusion, delamination, cracks, etc., and the surface hardened layer produced by the flame cutting groove should be removed.
2. Dimension deviation after steel plate processing: the deviation of plate width is less than 1.5 mm, the deviation of plate length is less than 2 mm, and the difference between diagonals is less than 3 mm.

Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management. Besides, we will create a harmonious business atmosphere, unblock the channels for employees to communicate, and build a stage for various sports and talents.
