Stud Bolts for the Petrochemical Industry

By 2030, the global petrochemical industry is expected to be worth around USD 798 billion. It's a high-value field, with equally high stakes. Any fluid leakage in a petrochemical plant could do serious damage to your business.

That is why it is important to use the right tools for the job at hand. Building a strong foundation for your petrochemical company starts by putting together durable, reliable equipment. And though they might seem like a small part of the larger whole, the stud bolts you choose can make all the difference.

If you're looking at our range of stud bolts and wondering which one is right for you, don't worry! We've put together this guide to learn more about the bolts we offer here at Konnect. Read on for advice on how to choose the right petrochemical stud bolts for the job.

What Are Stud Bolts?

Stud bolts are small threaded rods, used to fasten high-pressure flange connections in a petrochemical plant. One key advantage of a stud bolt is that both ends are completely threaded, which means they can be fastened in place with both nuts and sealing screws.

These bolts can be installed quickly and easily, making it a straightforward set-up process. They can also be dismantled easily, in case of situations where your team needs to repair or inspect equipment.

Stud bolts are available in a wide range of metals and alloys. Some manufacturers also offer protective coatings for stud bolts, nuts, and sealing screws.

Stud Bolts and Their Uses

The use of stud bolts in the petrochemical industry depends heavily on the material and construction of each bolt.

Most stud bolts are made from high-strength metal alloys incorporating substances like nickel, chromium, and manganese. These bolts can be used in highly challenging conditions. Since petrochemical equipment is often exposed to high temperatures and corrosive substances, these bolts are a vital part of almost any petrochemical plant.

However, some bolts are made from lower-strength materials, such as iron or aluminium. To compensate, these bolts are usually made with coarser threads, making them more likely to remain in place when fastened. Still, they are usually used in situations that need less precision in their fastening.

Some common uses for stud bolts in the petrochemical industry include:

Flange joints
High-temperature pipelines
Oil rig construction
Offshore platform construction

Choosing the Right Petrochemical Stud Bolts

When choosing stud bolts, it is important to understand what you plan to use them for. What conditions will they be exposed to? What do you need them to achieve?

Here are just a few of the factors you should consider when choosing the right stud bolts. Remember, your manufacturer should be able to advise you if you aren't sure! At Konnect, we have over 50 years of experience with many types of fasteners, and we work closely with our clients to ensure that you get the product you need.

Service Temperature

Temperature conditions in petrochemical systems can vary. Certain processes demand temperatures of up to 500ºC, while others may require temperatures well below zero. It's important to know which bolts are most suitable for which temperatures.

Certain bolts are a great fit for a huge range of temperatures. The A320 grade L7 bolt can withstand temperatures ranging from -101ºC to 538ºC, making it a great fit for a variety of functions and processes. Meanwhile, bolts like the A193 grade B16 can withstand extremely high temperatures but may not hold up in temperatures below zero.

You can choose the best bolt for your service temperature by understanding where your bolt will be used. It is of great help if you know the conditions you expect your bolt to face.

Strength

As we've already discussed, stud bolts come in a variety of materials, and not all of them have equal strength. If you expect your stud bolts to be used in high-precision or high-pressure settings, you will need to invest in a stronger bolt.

It's also important to know the difference between yield strength and tensile strength when choosing your stud bolts. Yield strength is the amount of stress a material can take before it risks permanent deformation – which can make it unusable. Tensile strength, on the other hand, is the amount of stress a material can take before it breaks.

We list the yield and tensile strengths of all our stud bolt products in our product catalogue, to help you make the most informed decisions.

Dimensions

It might seem obvious, but it's crucial to make sure that your stud bolts are the right size for the job! This isn't just a matter of making sure your fastening is secure. The dimensions of your bolt can affect its strength, elongation, and hardness, which can make a real difference to your equipment.

If you aren't sure about the best fit for your needs, we'll be happy to advise you personally!
