Types of Pressure Vessels We Manufacture
Explore the taxonomy below. Click a card to open details—built for EPC clarity and faster technical evaluation.
Process Pressure Vessels
Process pressure vessels are designed for chemical reactions, separation, heating, and controlled process operations. These vessels are engineered considering temperature, pressure, corrosion allowance, agitation loads, and inspection access to ensure safe, stable, and continuous plant performance.
Horizontal Pressure Vessels
Horizontal vessels are commonly used as separators, receivers, surge drums, and bullets, offering excellent phase separation, stable liquid hold-up, and easy installation on saddle supports.
Vacuum and Low-Pressure Vessels
These vessels are built to resist external pressure and vacuum conditions, using optimized shell geometry and stiffening to prevent deformation during operation.
Heat Exchanger Pressure Vessels
These vessels form the pressure-retaining shells and channels of heat exchangers, built to withstand thermal cycling, differential expansion, and tube bundle forces while maintaining long-term leak-tight performance.
Vertical Pressure Vessels
Vertical vessels are used for columns, reactors, absorbers, and tall process equipment, engineered for wind loads, seismic forces, and precise nozzle and platform integration.
Cryogenic and Low-Temperature Pressure Vessels
Cryogenic vessels are manufactured for extremely low temperatures used in LNG and industrial gas services, employing impact-tested materials and precision fabrication to maintain structural integrity.
Built for harsh service conditions.
Thermal cycling, corrosion allowance, fatigue loading, access for inspection, and field integration— engineered into every vessel from day one.

High-Pressure Gas Storage Vessels
Gas storage vessels are designed to safely contain compressed gases such as hydrogen, nitrogen, oxygen, and carbon dioxide, focusing on fatigue resistance, weld integrity, and rigorous non-destructive testing.
Jacketed Pressure Vessels
Jacketed vessels allow controlled heating or cooling of process fluids through a surrounding thermal jacket, making them ideal for polymers, resins, pharmaceuticals, and specialty chemicals.
Skid-Mounted Pressure Vessel Packages
Skid-mounted systems integrate vessels with piping, valves, instruments, and structural frames into a single engineered module for fast installation and reliable operation in process plants.
