Storage tanks are storage equipment that stores crude oil, gasoline, kerosene, naphtha, and various non-volatile chemicals. They are an important part of storage and transportation system facilities, oil refining, and chemical plants.

Why is the storage tank spherical? Because of all the shapes, the sphere is the structure with the best pressure capacity, the most stable, and the largest capacity. Therefore, most of the storage tanks are spherical.

Dalian Jiuying's spherical head machine specially manufactures this large spherical head.

Main technical performance and configuration of equipment

1. The equipment has digital display of stroke, numerical control of pressing stroke; digital display of pressure and numerical control; stroke and pressure can be controlled individually. This ensures that the curvature of each batch of ball pieces is smooth and uniform due to the setting of the pressing stroke.

2. The main plunger seal adopts the American Xiaban technology product of Guangzhou Research Institute.

3. The main cylinder and main plunger are made of high-quality carbon steel forgings. Forgings whose main cylinder meets the third-level flaw detection standard, the main plunger is quenched and tempered and chrome plated (Adjusting-grinding-plating-polishing)

4. The oil pump adopts Qidong high pressure pump.

5. The PLC adopts Siemens.
