Temporary Storage Tank

A temporary storage tank is a stainless steel storage tank that functions for temporary storage, temporary buffering, or material feeding. It is a commonly used type of stainless steel tank. It can be a fixed – type storage tank installed on the ground with supporting legs, or a mobile stainless steel storage tank, or a mobile material bucket. Its typical process applications include temporary storage, heating, heat preservation, etc.

A temporary storage tank is also called a stainless steel temporary storage tank, a stainless steel buffer tank, or a stainless steel surge tank. It is the most commonly used intermediate temporary storage equipment or storage equipment in industries such as pharmaceuticals, biology, food, fine chemicals (daily chemicals), and fermentation. The tank body is entirely made of SUS316L or SUS304 stainless steel. The inner surface of the tank body is mirror – polished, with a roughness Ra ≤ 0.4 μm.

• Classification by Form: It can be divided into vertical tanks and horizontal tanks.
• Classification by Pressure Requirement: Stainless steel pressure vessels and non – stainless steel pressure vessels.
• Classification by Structure: It can be divided into single – layer storage tanks, double – layer storage tanks (with an insulation layer), and three – layer storage tanks (with insulation and a jacket).

1. Operational Performance
   The accessories of the temporary storage tank (such as manholes, inlets and outlets, liquid level gauges, breathing valves, etc.) are reasonably distributed, making observation and operation simple and easy.
2. Sanitary Performance
   The heads are in the form of standard ellipses or dished shapes, and the rounded corners are formed by Japanese – style flat – plate hydraulic pressing; the joints of all nozzles are subject to drawing treatment to ensure that the corner parts transition smoothly in an arc shape, and the arc radius is ≥ 10 mm; all welds of the tank body are welded by automatic/manual argon arc welding and are subject to stress relief treatment; the inner and outer surfaces of the equipment are mechanically precision – polished to ensure that the roughness of the inner surface Ra ≤ 0.6 μm, effectively avoiding product residue, reducing cleaning difficulty, and meeting the requirements of hygienic – grade tanks. The inner surface is pickled and passivated to enhance the corrosion resistance of the equipment and improve the service life of the equipment.
3. Appearance Performance
   The outer surface is integrally sanded and treated to a matte finish by an automatic polishing machine, with uniform polishing lines. The upper and lower heads are polished to a mirror or matte finish, with a roughness Ra ≤ 0.8 μm, giving a pleasant visual feeling and avoiding light pollution.
