A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure, capable of being widely used in fields such as petroleum, energy, scientific research, military projects, railways, chemical engineering, etc. A pressure vessel is also a sealing equipment that can bear a certain pressure, through which the heat exchange of the medium, the physical and chemical reactions of the medium, the mass exchange of the medium, the purification of gases, the separation of solids, liquids and gases can be completed.
Polymerizing-kettles (poly-reactors): for polycrystalline silicon projects with a capacity of 800-1500 tons per year.
Polyvinyl chloride containers, reaction containers and heat exchangers: for caustic soda and PVC (polyvinyl chloride) projects with a capacity higher than 80,000 tons per year, and methanol and chloroethylene projects with a capacity higher than 100,000 tons per year
Air pressure tanks: for tests in aircraft design institutes, etc.
