Pressure Vessels That Demand Quality Engineering

The safety, durability and reliability of pressure vessels are critical and therefore require quality engineering. Companies that require pressure vessels demand the very best quality. So controlled production and rigorous testing are required.

Ensuring they’re built to ASME standards and using top-tier manufacturers for high pressure gas compressors, supercritical CO2 extraction equipment and custom reactor vessels.

What are pressure vessels?

Pressure vessels are closed containers. Housing liquids and gasses at a pressure that’s different to ambient pressure, they are often created using a range of materials.

They’re often used in a variety of industries where gas recovery systems and pressurized liquid storage are indicated. Whether that’s oil and gas, chemical or food processing industries. Types of pressure vessels that are typically created include heat exchangers, flash drums and reactors.

In order for pressure vessels to be appropriate for use, every manufacturing aspect needs to meet several standards and regulations. The ASME Boiler and Pressure Vessel Code is the one that is universally known by manufacturers of these containers.

How they’re made and their usage

Many of the pressure vessels are made of steel. Other materials include aluminum, stainless steel, and titanium, all of which are known for their durability. To manufacture such products, the steel is manufactured to the right thickness and cut to the shape required.

From a lab-scale high-pressure reactor that allows for reactions to pressure while resisting corrosive acids to a closed-loop CO2 extractor to extract cannabinoids. Both are examples of pressure vessels.

Types of pressure vessels and their material selection

There are a number of pressure vessel types that vary depending on their intended usage. A few examples include:

  • Storage vessels – Temporarily hold liquids, gases and vapors.
  • Heat exchangers – Help to transfer heat between two or more fluids.
  • Boilers – Utilizing fuel, nuclear or electrical power as heat.
  • Process vessels – Broader use for mixing and agitation, distillation, and mass separation to name but a few. 
  • Distillation columns – Separates a mixture of liquids based on their volatilities.
  • Industrial mixers – Powered with motor-powered blades to emulsify a single mixture or multiple mixtures.
  • Jacketed reactors – Maintain the temperature during a chemical reaction.

How their materials are selected

Part of manufacturing quality pressure vessels comes with knowing what materials are best for each task. Meeting the strength requirements and corrosion resistance are some of the physical attributes that can determine what materials are used. Other factors may be the return on investment and the availability of the materials in question.

The importance of quality and expert engineering

Using hydrogen compressor manufacturers that are skilled in the creation of pressure vessels and maintain ASME certifications is critical. A high quality pressure vessel requires strenuous testing at extreme conditions before being placed into service. The accidental release or leakage of contents of an untested unit can be a threat to the environment and the individuals working in close proximity of that vessel.

Producing cryogenic pumps for hydrogen gas recovery space, as well as CO2 extraction equipment for extracting botanical oils are just two applications of high pressure vessels. Visit to explore other applications.
