PED-Certified Pressure Equipment Manufacturing

Certified manufacturing processes.

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.

Understanding the PED Risk Categories

The potential hazard of a system scales directly with its pressure and stored energy. For this reason, the regulatory requirements under the Pressure Equipment Directive become progressively more stringent across four distinct classifications:

Category I:

Lowest risk, requiring relatively limited conformity assessment procedures.

Category II:

Increased risk, demanding heightened oversight and compliance measures.

Category III:

Higher risk, with stringent conformity assessment and quality assurance requirements.

Category IV:

Highest risk category, requiring the most rigorous assessment and direct involvement of a Notified Body.

The Module H Advantage

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.

Frequently asked questions

What is PED Module H certification?

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.

What categories of equipment can Orbital independently certify?
Under our Module H approval, Orbital can independently manufacture and certify pressure equipment from Category I up to Category III. This removes the delay of third-party design and fabrication approvals.
Can Orbital manufacture Category IV pressure equipment?
Yes. While Category IV equipment represents the highest risk and requires the mandatory involvement of an external Notified Body, Orbital is fully capable of manufacturing these systems and coordinating the entire independent approval process.
How are pressure equipment categories determined?
Equipment is classified into Categories I through IV based on its specific technical parameters, including operating pressure, total volume, the type of fluid or gas contained, and the associated stored energy risk.
Is PED compliance required for both the UK and EU markets?
Yes. Anyone placing qualifying pressure equipment into service on either the UK or EU market must successfully demonstrate compliance with the relevant pressure equipment safety regulations.
