Finding the Right Bespoke Fittings for High-Criticality Machinery

By Patrick Gomes | February 16, 2024

When it comes to high-criticality machine components, precision isn’t just a preference, it’s a necessity, and in industries such as the oil and gas, subsea and nuclear sectors, these components need to be able to withstand extreme conditions and perform flawlessly. 

In this blog, our experts at Wulfrun will guide you through the process of finding the right specialised fasteners for your critical applications.


Why are specialised fasteners important for critical applications?

In high-stakes industries, the failure of machine components isn’t an option. All it takes is for one bolt to fail and it could compromise the safety and performance of your entire operation. 

Issues such as degradation or corrosion could lead to millions in damages and operational stoppages, not to mention the immense risk it puts on the lives of workers.

The challenge is to create machine components that can endure the extreme conditions found in these locations, such as:

  • High temperatures 
  • High pressure 
  • Corrosive substances 
  • High salinity 
  • Radiation exposure 
  • Mechanical stress 
  • Abrasive conditions

Standard components crafted without specialised coatings or wear-resistant properties are not up to the task. The key to manufacturing fasteners with the structural integrity and functionality needed to endure these conditions is through specialised engineering and materials.


Quality assurance

With so much riding on the performance of your fasteners, you need to be confident in their reliability and integrity.

As a leading provider of specialised components, Wulfrun has gained our reputation and trust from high-stakes industries through our certifications and meticulous testing and manufacturing processes. 

All of our components adhere to a quality system accredited by LRQA to BSL3 and are API20E BSL3 approved to ensure the highest quality fasteners on the market. 

Mandatory procedures and controls are also put in place at every stage of our manufacturing process, from full traceability on material purchase to our on-site XRF spectrometry on finished products.

No matter what your industry or project requirements, our flexible approach to customisation means that we can design, manufacture and deliver any pipe or forged fasteners you need for your critical machinery.


Specialised Components for the MOD 

One example of how Wulfrun can overcome the challenges of unique customised components is a project we completed for the MOD (Ministry of Defence) in 2023.

The MOD approached Wulfrun because they required the fabrication of a wide range of customised machine components with specifications written in the 1950s.

When working with old machinery, finding replacements for damaged components can be a challenge, but through our industry-leading reverse engineering process, we were able to deliver all the components in all the necessary materials and specialised finishes, within the MOD’s deadline.
