Design and quality systems in accordance with Module H, supporting full quality assurance and compliance for pressure equipment up to Category IV for critical high-risk sectors.
Orbital Fabrications manufactures high-integrity pressure vessels, piping assemblies, and integrated pressure systems in strict accordance with the Pressure Equipment Directive (PED) 2014/68/EU.
Operating under a certified Module H quality system, we provide a full conformity assessment route that dramatically streamlines your timeline. Anyone placing pressure equipment onto the UK or EU market must demonstrate compliance with these safety regulations. By partnering with an accredited Module H manufacturer, you reduce compliance risk, accelerate certification, and bring complex, high-risk systems into service with absolute confidence.
We understand that gas systems are a critical part of the environments they support. That’s why we take a complete approach to the design and manufacture of high-purity gas equipment, combining specialist engineering knowledge with precision fabrication and assembly. From initial design through to welding and final assembly, our team maintains control over the process to ensure every system is built to the required specification.
This approach helps us deliver high-quality gas system solutions while supporting faster lead times and reducing the delays that can arise when multiple suppliers are involved. Whether supporting semiconductor, laboratory, clean energy or other high-specification environments, we deliver solutions engineered around the needs of each application.
Lowest risk, requiring relatively limited conformity assessment procedures.
Increased risk, demanding heightened oversight and compliance measures.
Higher risk, with stringent conformity assessment and quality assurance requirements.
Highest risk category, requiring the most rigorous assessment and direct involvement of a Notified Body.
Because Orbital Fabrications holds Module H certification, we possess the authorised quality systems to independently manufacture and self-certify pressure equipment up to Category III within the scope of our approval. While Category IV equipment requires the highest level of scrutiny, we can seamlessly manufacture these systems by managing the necessary Notified Body involvement and approvals on your behalf.


Module H is a full quality assurance conformity assessment route under the Pressure Equipment Directive (PED) 2014/68/EU. It certifies that a manufacturer operates a comprehensive, audited quality system covering design, manufacturing, final inspection, and testing.
Whether you need an independently certified Category III process skid or a highly regulated Category IV pressure vessel assembly, our Module H certified team is ready to deliver.
