Pressure Tanks Key Terms

Understand pressure tanks key terms in order to make smarter business choices

Pressure tanks are crucial to industries where you need to store gases or liquids at a pressure level different from that of the surroundings.

Different laws govern the design and manufacture of pressure tanks and you need to be aware of the jargon used in this industry. Incorrect maintenance of pressure tanks can pose a threat to life and property, making it crucial for people involved in the pressure vessels industry to know all about the types, operation and maintenance of pressure tanks.

This guide explains key industry terms, such as fabrication, hydro-pneumatic tanks and PVP materials.

Fabrication

You will frequently hear about fabrication in the pressure tanks industry. Fabrication is the manufacturing of pressure tanks through a process that involves metal cutting, welding and assembling of the materials.

Hydro-pneumatic tanks

Hydro-pneumatic tanks are pressure vessels that can contain both liquids and gases.

Dewars

Dewars are pressure tanks that can sustain extremely low, cryogenic temperatures and most commonly store liquid nitrogen. Steel dewars are common in the industry because they can withstand damage associated with very low temperatures.

ASME pressure vessels

ASME pressure vessels are tanks built to the Boiler and Pressure Vessel Code as per the requirements of the American Society of Mechanical Engineers. This code ensures that the tank meets the required quality standards.

PVP materials

To manufacture pressure tanks, you can choose from various PVP materials (pressure vessel and piping materials) depending on the purpose of the tank.

Failure analysis

When you are working with pressure tanks, you must take every precaution to prevent tank breakdowns. Failure analysis will help you identify design errors, cracking and welding problems and take necessary actions.
