Conical Head

The conical head is one of the most widely used sealing structures for pressure vessels. It is mainly utilized to adjust fluid flow rates, change vessel calibers, or serve as the bottom sealing structure for material discharge. It is extensively applied in pressure-bearing equipment for chemical processing, energy production and other industrial fields.

Conical heads are categorized into two major types: flanged conical heads and non-flanged conical heads. Each structural type complies with dedicated standards for geometric dimensional tolerances and forming tolerances. Relevant specifications also regulate material requirements: raw material performance and retest procedures must conform to general industry standards, while manufacturing processes shall strictly meet the criteria for thickness reduction ratio and surface appearance quality control. Meanwhile, standardized guidelines for non-destructive testing and pressure testing are implemented to ensure the pressure resistance and operational safety of conical heads for pressure vessel service.

In practical scenarios, conical heads are widely adopted in chemical engineering, energy, food processing, pharmaceutical and other industries. In chemical reactors, they optimize material flow patterns to improve reaction efficiency. In industrial boilers for the energy sector, they facilitate steam collection and discharge to boost energy utilization. In food fermentation tanks, they enable smooth material discharge and convenient cleaning, ensuring production hygiene. In pharmaceutical sterilization equipment, they guarantee uniform and safe sterilization operations.

Compared with other vessel head types, conical heads feature low fluid resistance, smooth material discharge and space-saving structure, perfectly catering to the differentiated operational demands of various industrial applications.
