ASME Section VIII pressure vessels are essential process equipment that use high heat and high pressure and/or a catalyst to create a chemical reaction resulting in a new substance.
At Tate Metalworks our custom pressure vessels and tanks are considered among the highest quality in the industry. We pride ourselves on our leading reputation of quality, materials of construction, shop fabrication and field erection. We hold an ASME Section VIII Division 1 U-Stamp and follow the ASME Quality Control Program ensuring full traceability of material sourcing, fabrication, and testing. All of our welders are ASME Section IX certified welders.
Our commitment to quality, safety and innovation ensures your pressure vessels operate at peak performance and reliability long-term.
We understand that precision engineering and meticulous construction are essential for the safe and reliable operation of ASME pressure vessels and pressure tanks. Our commitment to quality is reflected in every step of the process:

- Material Selection: We only source the highest grade of materials, including stainless steel, duplex stainless steel, carbon steel, and nickel alloys to ensure your tank is designed to meet your specifications for long-term performance.
- Welding Procedures & Certifications: We have over 400 qualified welding procedures and each welder is certified under ASME Section IX.
- Stringent Quality Control Measures: From material selection to final inspection, our quality control measures strictly follow ASME standards ensuring that every vessel exceeds your expectations.
- Thorough Inspection and Testing: Each pressure vessel undergoes inspection and testing per ASME standards to ensure it meets all safety and performance benchmarks.
ASME pressure vessels are designed to meet various industrial needs with a range of configurations and applications.

Common Pressure Vessel Configurations
ASME pressure vessels offer a variety of configurations to suit diverse needs across industries.
