We’re based in Abingdon, Oxfordshire, but we work with clients across the UK and internationally. While we support a wide range of regulated industries, we’re particularly known for our expertise in cryogenic pressure vessels, especially in healthcare applications where performance and precision are critical.

Our precision welding and fabrication capabilities are trusted by clients operating in the most demanding environments. We specialise in high-integrity pressure vessels and containment systems engineered to withstand extreme temperatures and pressures, while meeting the highest regulatory and quality standards.

Backed by over 40 years of experience, advanced automation, and one of the UK’s largest teams of coded welders, we deliver pressure vessels where performance, compliance, and reliability are critical.

You’re welcome to provide your own design, but it’s not a requirement. We work closely with clients at every stage, offering full design support, including pressure calculations, weld design, and manufacturing data.

Using advanced CAD, CAM, and CAE software, our engineering team can develop or refine designs to meet technical standards and ensure manufacturability. We also apply DfMA (Design for Manufacture and Assembly) principles to optimise performance, cost, and production efficiency.

To design a pressure vessel tailored to your needs, we typically gather the following technical details:

• Size (diameter, length, or capacity)
• Orientation (horizontal or vertical)
• Type of supports (saddles, legs, skirt, or lugs)
• Design pressure (internal and external)
• Design temperature (minimum and maximum)
• Corrosion allowance (if applicable)
• Material of construction
• Product details (including specific gravity)
• Openings (quantity, size, type, and location)
• Internal lining or external paint requirements
• Appurtenances (e.g., internals, insulation supports, ladders, platforms)
• Installation location (for wind/seismic design and freight estimation)

Don’t worry if this looks overwhelming, our engineering team will guide you through every step, ensuring nothing is missed and every requirement is met.

Our manufacturing processes are certified to ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety). We also manufacture in accordance with global pressure vessel codes and fabrication standards, including:

• ASME VIII Div.1
• PD 5500
• AD 2000-Merkblatt
• EN 13445
• ISO 3834
• EN 1090

If your project requires compliance with additional standards, our team will work with you to meet those specific technical and regulatory requirements.

We use a combination of manual, semi-automated, and fully automated welding techniques designed to suit each project’s requirements. Our capabilities include:

• MIG (Metal Inert Gas)
• TIG (Tungsten Inert Gas)
• Autogenous DC TIG
• MAG (Metal Active Gas)
• Plasma Keyhole
• Robotic TIG/MIG
• SAW (Submerged Arc Welding)

These processes are carried out by our team of experienced, coded welders, ensuring precision, consistency, and compliance across every build.
