The Need for Pressure Vessel Inspection & Why They Matter

In any industrial setting, anything that is functioning or performing under high pressure is prone to cause serious damage if not working properly. Anything that is pressurized means that it is operating under very specific circumstances and requires every component to do its part. From industrial boilers to other pressure vessels, to your typical pressure washer or water tanks, the importance of maintaining and keeping these vessels secure is absolutely essential.  As certified inspectors of pressure vessels, we understand the necessity for quality upkeep and maintenance of these vessels. 

What is a Pressure Vessel?

To those that work in the industry, a pressure vessel is an everyday occurrence and necessity.  For others, it might sound very exotic but really it refers to any vessel that is operating under high pressures. Most pressure vessels are for industrial use like hot water storage tanks and dividing cylinders.  They can also be used to hold toxic and other non-toxic liquids. For this reason, these are carefully fabricated enclosed containers. They are primarily designed to hold gasses or liquids at high pressures or varying pressures.

These vessels serve a variety of purposes in industrial settings, factories, or installations. Because of the inherent dangers present in anything that involves contained and pressurized gas or liquids, there are stringent regulations and safety protocols that must be met. 

The most common shapes for pressure vessels include:

  • Spheres
  • Cones
  • Cylinders

How are Pressure Vessels Made? 

Because of the high pressure, they must withstand, these vessels will typically be fabricated out of different types of steel. Many will use carbon steel and stainless steel. When fabricating a cylindrical vessel, for example, different steel parts must be welded together to form the shape and ensure safety.

Subpar welding can lead to the compromise of quality, which means that precautions are necessary to ensure the parts are correct and properly installed. Only certain kinds of steel are appropriate for certain parts, as per regulations. Engineering standards require that only steel with high impact resistance should be used for pressure vessels. 

The bodies that establish these fabrication codes include ASME safety guidelines and the National Board of Boiler & Pressure Vessel Inspectors in the U.S. and the EU Pressure Equipment Directive in Europe. Other regulations around the fabrication of these vessels include the use of a load-bearing liner that helps withstand the pressure load. These will typically be composed of metal, ceramic, or polymer. 

What Happens When a Pressure Vessel Loses Integrity or is Cracked? 

If a vessel becomes cracked or damaged it can lead to rupture or leakage. None of these is good news. The potential health hazards that come with either of the above are serious and include poisonings, suffocations, fires, and even explosions. If the energy in the vessel expands and puts added pressure that the vessel is not able to withstand, it is a recipe for disaster.

What is an Industrial Pressure Vessel Inspection? 

Faulty pressure vessels lead to catastrophic consequences. This is why various governmental bodies have stepped in to ensure that there are frequent inspections that maintain the performance and integrity of these vessels. 

The inspection process will look at:

  • How well the vessels meet established industry standards
  • The vessel while empty and in operation
  • Several kinds of pressure tests will be conducted 

As mentioned above there are several ways that a pressure vessel can be inspected. The inspection must happen by someone that is certified through the Board. They might conduct a:

Internal inspection: This type of careful examination of the vessel happens when it is empty and not in operation. This inspection is used to identify internal damage, corrosion, worn-out components, etc. The welded seams will be looked at carefully, as well as other areas near welds and fittings. 

External inspection: This is a type of inspection that is done while the vessel is operational. External inspections are conducted on the outside of the vessel. These are important to catch malfunctioning external components like the piping, connections, and more. 

How Often are These Pressure Vessels Inspected? 

This might vary depending on the particular use for that vessel.  Pressure vessels that house toxic liquids, for example, will need more frequent inspections. Preventative maintenance is the best way to ensure successful inspections and avoid fines, loss time of operation, damage, and —most importantly— accidents and malfunctions.

An Ode to Combustion and Why Combustion Control Matters

a close-up shot of an internal combustion engineOh where would we be without combustion? Well, life would surely have progressed differently. If you own a car that runs on gas or diesel, then the combustion engine has become part of your life. The engine is the heart of the vehicle, as it is what pumps the necessary fuel through the engine to get it up and going. Because it is now so ubiquitous, most people don’t think about the internal combustion engine even though it likely is responsible for their daily commute. And while most people know that the engine is vital, we might not understand just why this engine is the best type. This type of engine was really the beginning of a lot of key manufacturing processes, so we thought why not pay tribute to it. That’s because today many of our industrial boilers use this technological concept to produce steam or hot water for space heating or process heating. 

There are essentially two types of combustion engines: an internal and an external combustion engine. In the latter, the fuel source—usually coal— is burned outside the engine. Then, the burning fuel will give it the energy it needs to run. 

An internal combustion engine works a bit differently. Instead of heating the fuel on the outside, a mixture of fuel and oxygen is injected into the engine. From there, there is a spark that ignites the fuel that causes it to make tiny explosions. This is why, of course, spark plugs are quite important to the whole operation. 

Over 150 years, the design of the internal combustion engine has been worked on and perfected and is by far the most preferred way to power a vehicle. When it comes to vehicles, this brings an advantage in using petrol or diesel as its fuel source because it can last longer. 

The invention of this type of engine was almost reached by several people simultaneously. Like many great inventions in human history, it seems that several minds across the world often come to it around the same time. Ultimately it was a man named Jean Joseph Etienne Lenoir that patented the first combustion engine. Early iterations of the invention had only one cylinder. This often caused the engine to overheat, but it was able to power small vehicles. This was a huge milestone in the technology as there was an ability for it to run continuously. And then, thanks to several great scientific minds of the 19th and 20th century, the internal combustion engine was improved and became the most efficient engine. 

Combustion Systems in Boilers and Industrial Machinery 

After all, boilers use a lot of energy and take a lot of energy to run properly. They are made to produce hot water or steam through the combustion of a fuel. The combustion efficiency is important to consider for any business or commercial facility that utilizes these. There are more than 45,000 industrial and commercial boilers in the United States. These are boilers with a total fuel input capacity of 2.7 million MMBtu/hr. A combustion system for industrial boilers is a system designed to maintain a proper air/fuel mixture under varying load conditions and safe limits. 

Boilers can be categorized by water temperature and/or steam pressure. They can also be further classified by the type of metal they are constructed with. Typically, however, they will be built cast iron or welded steel. Boilers are rated in different ways and are measured with Btu/h or BTU per hour and MBtu/hr indicates the rate of input. 

 Many large commercial sites often wonder how they can increase the efficiency of their boiler function. There are essentially three ways to do this and they include replacing the boiler completely, replacement of the burner, or installation of a combustion control system. Having a combustion control system installed can help some facilities earn efficiency without having to spend the upfront costs of a full replacement. 

Combustion control systems work through continuous feedback from measurements of oxygen, carbon monoxide, and nitrogen oxide concentrations. This allows the combustion system to improve combustion efficiency while maintaining low carbon monoxide and nitrogen emissions. It also allows for continuous monitoring of boiler performance. 

A test conducted on the combustion control system in the Watervliet Arsenal in New York showed significant savings over the course of a year. The efficiency gain comes from various factors including the constant monitoring of carbon monoxide, which prevents inefficient and unsafe combustion to occur.
