This component is used in the following industrial products
A vessel in a distillation column system that collects condensed overhead vapor and returns a portion as reflux to the column.
A pressure vessel in waste heat boilers that collects and removes solid impurities (mud) from boiler water.
The primary pressure-containing component of a chemical reactor where chemical reactions occur under controlled conditions.

Manufacturer profiles associated with Heads.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ellipsoidal (2:1 ratio) heads are most common for standard pressure applications, while hemispherical heads are used for higher pressure services due to better stress distribution.
Carbon steel offers cost-effectiveness for non-corrosive services, while stainless steel or clad materials provide corrosion resistance for acidic or high-purity applications in chemical manufacturing.
