What is an unfired pressure vessel?
Unfired pressure vessels such as air and water storage tanks are vessels that have not been exposed to burner fire or combustion. Due to this, there is less risk for overheating and unfired pressure vessels have a proven track record in preventing corrosion through heat exchange.

What is an API 510 Inspector?
Certified API 510 Pressure Vessel inspectors must have a broad knowledge base relating to maintenance, inspection, repair, and alteration of pressure vessels. The API 510 examination is designed to determine if individuals have such knowledge.
How many types of pressure vessels are there?
Types of Pressure Vessel Heads Cylindrical, horizontal, and vertical pressure vessels are the most common kinds of vessels and they all require specialized ASME caps on each end. These caps are called “heads” and there are three primary kinds.
What is the difference between fired and unfired pressure vessel?
As Paul wrote, fired vessels are those that come in direct contac with fire (burning fuel), as typically boilers are, while unfired vessels are pressure vessels for liquids or gases under pressure, but not in contact with fire. For example, a water/water heat exchanger is an unfired vessel.
