Pressure Vessels Engineered
for Corrosive
& Critical Plant Environments
Designing pressure vessels for corrosive and critical plant environments requires careful consideration of material selection, vessel design, and fabrication standards based on actual process conditions.
With extensive experience in specialty non-ferrous metals, ATX provides engineering-based solutions that go beyond fabrication, supporting material selection, vessel design, and manufacturing aligned with real operating conditions.
Pressure Vessel Types Manufactured by ATX
Vertical Pressure Vessel
A vertical pressure vessel design engineered for high-pressure and high-temperature processes, widely applied in reactors, absorbers, and process service applications where efficient phase separation, compact footprint, and resistance to corrosive media are required.
Widely Applied Vertical Vessel Fabrication Reference
- Widely used vertical pressure vessel configuration for reactors, absorbers, and process service
- Suitable for a wide range of pressure, temperature, and corrosive media
Horizontal Pressure Vessel
A horizontal pressure vessel configuration engineered for stable operation and ease of maintenance in large-capacity chemical and industrial processes, applied where horizontal arrangement is required due to process layout, installation constraints, or operational accessibility.
Layout-Driven Horizontal Vessel Fabrication Reference
- Applied where horizontal arrangement is required due to process layout or installation constraints
- Commonly used for storage, separation, and buffer service
Jacketed Pressure Vessel
A jacketed pressure vessel structure engineered for precise temperature control through external heating or cooling, widely applied in reactive and temperature-sensitive processes where accurate thermal management is critical.
Precision Jacketed Vessel Fabrication Reference
- Pressure vessels equipped with an external jacket for heating or cooling service
- A configuration requiring jacket forming, shell-to-jacket welding, and dimensional accuracy control
Lined Pressure Vessel
A lined pressure vessel design engineered with a corrosion-resistant internal lining to protect the base material from aggressive chemical environments, ensuring long-term reliability and extended service life under demanding process conditions.
Corrosion-Resistant Lined Vessel Fabrication Reference
- Pressure vessels with an internal lining applied to address the corrosive characteristics of the process media
- A configuration where close adhesion and joint quality between the vessel shell and lining are critical
Custom-Designed Pressure Vessel Configuration
Custom-engineered pressure vessel configurations developed for process conditions where standard designs are not suitable, tailored to specific operating requirements, materials, and regulatory standards.
Non-Standard Geometry Pressure Vessel Fabrication Reference
- Applied to processes where standard pressure vessel configurations are not suitable
- Configured with non-standard geometries according to specific process conditions
Why ATX Pressure vessel
35+ years of supply experience in chemical and plant environments
With extensive experience, we support corrosion-sensitive plant environments by supplying pressure vessels designed for stable, long-term operation.
Integrated fabrication control for consistent quality
Core fabrication processes, including forming, welding, and testing, are managed in-house to maintain consistent quality. The entire workflow—from material sourcing to vessel fabrication and delivery—is integrated within a unified system.
Proven experience in certification and regulatory compliance
Experience with domestic and international certification requirements for pressure vessels. Inspection and testing are conducted in accordance with project specifications, either in-house or through certified third-party agencies.
Materials We Work With
