API 650 mechanically-anchored steel tanks bottom reinforcing plate

Sand blasting and derusting of API 650 mechanically-anchored steel tanks uses compressed air as power and SiC, pomegranate sand and quartz sand as spraying materials to form high-speed jet beam, which is used to remove rust and dirt on the surface of metal storage tank and improve the binding force of workpiece with coating and plating material. Sand blasting is often used in API 650 mechanically-anchored steel tanks construction.

Temporary Openings after Hydrostatic Test
When approved by the Purchaser in writing, and only in the case of tanks which when complete have no shell penetrations, it is permitted to restore by welding up to four temporary shell openings after the hydrostatic test in accordance with the provisions of this section. Each temporary opening shall be restored by the insertion of a shell plate that matches the thickness and specification of adjacent shell material, and is welded into place with full fusion butt-welds. The API 650 mechanically-anchored steel tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API 650 mechanically-anchored steel tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.
