When Is Pressure Vessel Engineering Used?

When Pressure Vessel Engineering Used

Pressure vessels are containers that are built to hold gases, vapours, or liquids at high pressures, typically above 15 psig. Pressure vessels are commonly used in the chemical processing, pharmaceutical, brewing and petroleum refining industries as heat exchangers, boilers and storage tanks. Each vessel has its unique specifications and operating limits that are built-in by custom design and engineering often referred to as design temperature and design pressure. Exceeding these operating limits could damage the vessel or lead to catastrophic failure and loss of containment.

Industry Standards And Practices

Because they work under immense pressure, a faulty, leaking or ruptured pressure vessel can be extremely dangerous, causing potentially lethal gas/chemical leaks and even massive explosions. It is because of this that pressure vessel engineering must be done with utmost care and perfection. There are specific standards and industry best practices that guide the designing, construction, maintenance, and inspection of pressure vessels. Some of the key standards that all pressure vessels must adhere to include:

  • API 510- The API 510 is a standard that governs In-Service alteration, repair, rating and inspection of pressure vessels. 
  • ASME VIII – This is a pressure vessel and boiler code that offers detailed requirements for the design, construction, testing, inspection and approval of various types of pressure vessels.

Pressure Vessel Engineering

There are 2 main approaches in pressure vessel engineering; engineering by code and engineering by analysis.

A pressure vessel can be engineered based on the formula and rules specified in the standards. Engineering by code allows you to build a vessel that is safe to work under the required design temperature and design pressure. More recent in pressure vessel construction is engineering by analysis. Engineering by analysis is used where the specifications or structure of a vessel are not covered by the available standards and design codes.

Pressure Vessel Engineers

Pressure vessel engineers are the professionals tasked with the designing, fabrication, testing, repair, maintenance and inspection of pressure vessels. They are the only people who are qualified and approved to undertake this highly technical work due to its sensitive nature. Pressure vessel engineers have experience in building pressure vessels that follow the relevant codes and standards. They also have the necessary skill set to offer sound advice on pressure vessel engineering based on analysis.

Many people in the pressure vessel industry consider the design standards and codes to be advisory, meaning various accommodations can be made in cases where the codes and standards simply do not apply. When an engineer wants to push the limits imposed by the design codes, the engineering by analysis approach is considered the best because it offers more accurate stress-testing results.

The different stress parameters, such as bending stress intensity, and membrane stress intensity or bending stress, can be assessed more precisely and accurately when an engineering by analysis approach is used in pressure vessel construction.

Engineering by Analysis Is Taking Over

Engineering by analysis is gradually overtaking the more conventional approach of pressure vessel construction which tends to lean more towards following rules rather than providing efficiency, safety and durability. More demanding designs in terms of safety and reliability together with the cost of production are the main factors that have contributed to this gradual advancement in pressure vessel engineering techniques.

Many customers and industry stakeholders are now calling for a review of the existing pressure vessel design codes and standards in order to provide a wide framework for pressure vessel engineers and designs. Although strict adherence to applicable codes and standards cannot be ignored, engineering by analysis should not be completely ruled out because of all the amazing benefits this approach has to offer.

Why Is Pressure Vessel Design Important?

Why Pressure Vessel Design Important

Although there are many sectors and industries that use stainless steel pressure vessels on a day to day basis, there are many people who still do not understand how pressure vessels work, as well as their importance in various applications. Pressure vessels are usually one of the largest components that many pieces of equipment required to function correctly. 

Pressure vessels are specially designed to store liquids and gases in a safe and secure manner. The use of pressure vessels has become standard among many homes and businesses. Professional engineering design services understand the importance of using proper design when building pressure vessels in order to prevent accidents from taking place. 

Where Are Pressure Vessels Used?

Pressure vessels were initially used in industries like mining and nuclear reactors. Over the years, their use has expanded to include many other sectors and industries. Currently, pressure vessels are used by ordinary people in activities like distillation and heating water. Pressure vessels are capable of storing liquefied gas in a safe, convenient and reliable manner. They are also used in storing and disposing of unstable substances and chemicals like LPG, ammonia and propane.

Pressure Vessel Design

When most people think of pressure vessels, they imagine large metal cylindrical tanks. While this may be the most popular pressure vessel design and shape, it is not the only one. There are many other acceptable shapes and form factors like cones and spheres. Of all other form factors, many professionals agree that a sphere is most reliable. Unfortunately, many designers and manufacturers claim that this design is both costly and difficult to implement. Consequently, consumers are forced to settle for cylindrical pressure vessels.

Components Of A Pressure Vessel

Pressure vessels have varying parts depending on the contents housed inside. Many vessels are custom-made for a specific purpose or use like storing butane. In most instances, people have to buy or build a pressure vessel to hold one type of substance or material. There are laws that govern how pressure vessels should be designed and built in order to meet various safety guidelines. Using wrong designs, materials or construction methods can cause spills, leakages and dangerous blasts that can injure people or cause damage to property.

Codes And Regulations

If you are looking for a pressure vessel for your home or business, there are several things to consider before acquiring it. There are specific laws and guidelines that vary from country to country that govern the making and operation of pressure vessels. The most important thing to keep in mind is the specific code that a vessel must adhere to depending on its contents and application. Getting advice from a professional inspector is mandatory when applying for a permit or renewing one. This process is very crucial to prevent accidents and protect both people and the environment.

Importance Of Pressure Vessel Inspection

Pressure vessels need to be regularly inspected to ensure optimal performance and safety. Usually, in the event of failure, pressure vessels release a huge amount of energy and content. There can be catastrophic consequences like the vessel throwing high-speed projectiles or a massive shockwave of its contents. Pressure vessels and storage tanks fall under different categories based on their threat. Any sort of failure in design or construction can endanger the lives of employees. Failure can also lead to deadly and poisonous substances escaping into the environment resulting in toxic contamination.

Failure to undertake regular inspections can have severe consequences. Using poor designs and materials when building pressure vessels can have fatal results. Pressure vessel design must adhere to the set rules and guidelines imposed by regulatory bodies in your state and country. Often, states have very strict rules governing the building, sale and operation of pressure vessels.
