Pressure equipment
First In Service manufactures pressure vessels, tanks, piping modules and skids designed to EN 13445 under the Pressure Equipment Directive 2014/68/EU. Equipment above the Article 4 category thresholds is built under notified body surveillance in carbon steel, stainless, duplex and super duplex, up to 25 × 5 × 5 m and 25,000 kg, with full traceability.
PED-certified pressure equipment, built to contain what cannot leak.
We manufacture certified pressure vessels, tanks, piping modules and skids for oil & gas, process and offshore applications, in strict compliance with PED 2014/68/EU and international safety standards.

Questions procurement teams ask
Are you PED certified?
Yes. Pressure equipment is manufactured to PED 2014/68/EU, with fully compliant documentation.
What pressure equipment do you manufacture?
Pressure vessels, tanks, piping modules, and skids for process, oil & gas, and offshore applications.
What materials are used for pressure equipment?
Carbon steel, stainless steel, duplex, and super duplex, selected to the service conditions and PED category.
What NDT is performed on pressure equipment?
VT, PT, MT, and UT to the scope required by the PED category and client specification, performed by certified partners.
What documentation ships with pressure equipment?
PED conformity documentation, material certificates (EN 10204 3.1, 3.2 on request), and NDT reports.
Can you handle hydrogen and carbon capture equipment?
Yes. Pressure equipment to PED 2014/68/EU in duplex, super duplex and stainless steel is the same discipline used for hydrogen storage and CCUS process equipment.
PED compliance as a production method, not a paperwork sprint
Pressure equipment manufacturing is regulated for a reason: when it fails, stored energy is released. PED 2014/68/EU compliance therefore cannot be pieced together afterwards from whatever records survive production; it has to be designed into the build. We classify the equipment category at the quoting stage, agree the conformity assessment route, and structure production so every hold point generates its record as it happens: heat numbers verified at material receipt, weld procedures and welder qualifications matched to each joint, NDT scope executed per category requirements.
Duplex and super duplex demand particular discipline: heat input control during welding, verified ferrite balance, and pickling that restores the passive layer. These are process parameters we control and log, because a stainless vessel that corrodes in service is a materials failure that started in the workshop.
Production closes with a hydraulic or pneumatic pressure test to specification, witnessed where required. The vessel ships with its complete PED documentation package, ready for conformity declaration and commissioning, with no missing certificate to hold up your schedule.
Where this capability goes to work.
Marine, offshore & subsea
Pressure systems for marine and offshore installations.
Marine, offshore & subsea →The same facility, with the evidence each sector asks for.
Rotating parts & shafts
Impellers, casings, rotors, shafts and turbine housings to ±0.02 mm.
Rotating parts & shafts →Mining & machine building
Crusher frames, conveyor structures and wear-resistant steel assemblies.
Mining & machine building →Hydrogen and carbon capture use the same discipline.
PED-certified pressure equipment in duplex and super duplex is the core competence behind hydrogen storage vessels and CCUS process equipment. The materials, weld procedure control, ferrite balance verification and documentation package are the same ones we work with every day. If your project is in this space, the capability is already here: talk to us about scope before you assume it needs a specialist.
