Pressure Vessel

Pressure Vessel

Doosan Mecatec manufactures pressure vessels of various materials and sizes, being the world’s largest producer. Furthermore, to secure competitiveness of small- and mid-sized equipment, Doosan VINA (based in Vietnam) is in operations.

Pressure vessels are closed containers designed for the storage, reaction, and separation of fluid (liquid or gas) to withstand the pressure of internal fluid.
