Certified to Perform: Gilwood’s Pressure Vessel Standards

Introduction:

When it comes to pressure vessels, certification isn’t just a formality—it’s a mark of quality, safety, and long-term reliability. Whether you're operating in food production, pharmaceuticals, energy, or chemicals, your equipment must comply with stringent international standards. At Gilwood, we take this responsibility seriously. Every pressure vessel we manufacture is certified to perform, engineered to the highest standards, and tested to withstand the most demanding industrial environments.



Meeting International Standards – Without Compromise

Our pressure vessels are built to conform with the Pressure Equipment Directive (PED) and carry certifications under several key global standards, including:

  • CE and PD 5500 (Categories 1, 2, and 3)

  • ASME VIII Div I (‘U’ Stamp)

  • ISPESL, AD-Merkblätter, Stoomwezen, and others

This multi-standard approach means we can deliver pressure vessels suitable for use in the UK, Europe, North America, and beyond—with complete traceability and peace of mind.



Precision Engineering for High-Performance Operation

Every Gilwood vessel is engineered using the latest design tools and techniques, including:

  • Solid Edge 3D CAD modelling

  • Finglow Pressure Vessel Design Software

  • Finite Element Analysis (FEA)

  • Nozzle load, wind load and seismic load calculations

This engineering depth ensures that each vessel is designed specifically for its intended pressure, temperature, and location—resulting in a durable, compliant and efficient solution.



Thoroughly Tested, Every Time

Certification is only meaningful if it’s backed by testing. At Gilwood, every vessel undergoes a rigorous programme of Non-Destructive Testing (NDT) to verify structural integrity and operational safety. Our testing capabilities include:

  • Leak Testing

  • Hydraulic Pressure Testing

  • Vacuum Testing

  • Heat Treatment

  • Proof Load Testing

This process guarantees that every vessel leaving our facility has been validated and approved to meet both regulatory and customer-specific requirements.



Materials That Meet the Challenge

We manufacture vessels using high-quality materials selected for their performance in challenging industrial environments. These include stainless steel, Hastelloy, Duplex, and Super Duplex —each offering excellent strength, corrosion resistance, and suitability for specific chemical or hygienic applications. This material versatility ensures our vessels are ideal for industries where safety, cleanliness, and long-term durability are non-negotiable.




A Reputation Built on Certification and Trust

With over 60 years of manufacturing expertise, Gilwood has earned a reputation for delivering pressure vessels that combine technical excellence with uncompromising standards. Whether it’s a bespoke design or a multi-vessel project, we deliver equipment that’s built to perform—and certified to prove it.



Designed to Comply. Built to Last.

When you choose Gilwood, you’re not just buying a pressure vessel—you’re investing in compliance, reliability, and engineering excellence. Our commitment to recognised international standards ensures that your equipment is ready for inspection, safe to operate, and built to last.
