Prefabrication of tank shell plate of stainless steel storage tank

Stainless steel storage tanks are sanitary and clean stainless steel vessels and equipment with single-layer or multi-layer vertical or horizontal structure. It is an intermediate buffer and liquid storage equipment commonly used in pharmaceutical, bioengineering, food, beverage, fruit wine, condiment, chemical industry, oil and other industries.

The prefabrication method of tank shell plate of stainless steel storage tank is as follows:
1. For storage tanks with a diameter of less than 25m, the shell plate width shall not be less than 1000mm and the length shall not be less than 1000mm;

2. For storage tanks with a diameter greater than or equal to 25m, the shell plate width shall not be less than 1000mm and the length shall not be less than 2000mm;

3. The distance between the longitudinal weld of the bottom ring shell plate and the butt weld of the tank bottom edge plate shall not be less than 300mm, and the distance between the longitudinal weld of the upper and lower ring shell plates shall not be less than 500mm;

4. The distance between the edge of the opening connecting pipe or the reinforcing ring plate of the opening connecting pipe on the tank wall and the longitudinal circumferential seam of the tank wall shall be greater than 8 times the size of the welding leg and not less than 250mm.
