Petrochemical and Vessels

Armultra provides a comprehensive range of pressure vessel and petrochemical engineering services, including design, fabrication, inspection, installation and commissioning.

We deliver both on-site and off-site solutions tailored to client-specific project requirements, supporting safety-critical and regulated industries across the UK and internationally.

Pressure Vessel Design & Manufacture

We design and manufacture pressure vessels in accordance with recognised national and international codes, including:

• PD 5500

• ASME Section VIII (Division 1 & 2)

• Lloyd’s Register Rules

• Pressure Equipment Directive (PED)

• Pressure Equipment (Safety) Regulations (PE(S)R)

Armultra operates an approved PED Module H quality system, enabling us to act as the legal manufacturer where required and undertake full conformity assessment and certification.

Our procedures, facilities and qualified personnel ensure vessels are manufactured to meet structural integrity, pressure containment and regulatory compliance requirements.

In-House Vessel Engineering & Design

Armultra offers in-house vessel design and engineering capability, delivered either as:
