TANKS AND
PRESSURE VESSELS
Critical equipment designed for performance and compliance
DESIGN, FABRICATION, AND REPAIR OF CERTIFIED PRESSURE VESSELS
Groupe PMI offers complete management of your industrial tank and pressure vessel projects, from engineering to commissioning.
Our teams intervene at every stage of the equipment lifecycle: design, fabrication, installation, inspection, repair, dismantling, and relocation, adapting to the specific requirements of each industrial environment.
These services can be carried out in their entirety or on a targeted basis, according to your needs.
Thanks to advanced technical expertise and rigorous execution, each project is conducted with precision, in compliance with the cleanest industry standards.
Our interventions are performed exclusively in a framework not subject to the construction decree, offering greater execution flexibility and increased efficiency for our industrial clients.
Recognized Certifications
Pressure Vessels (ASME)
Groupe PMI designs, manufactures, and installs pressure vessels compliant with ASME Section VIII Division 1, ASME B31.1, and B31.3 standards, integrating rigorous design of cylindrical shells, formed heads (elliptical, hemispherical, or torispherical), and structural components.
Each equipment is dimensioned using advanced engineering calculations, taking into account internal pressures, thermal loads, mechanical stresses, and corrosion factors. Fabrication relies on certified welding procedures ensuring structural integrity and leak-tightness of the assemblies. Our vessels are designed to withstand severe conditions, while guaranteeing safety, regulatory compliance, and long-term durability.
Standards & Compliance: Design, fabrication, and installation compliant with ASME Section VIII Division 1, ASME B31.1, and B31.3 standards.

Extended Lifespan: Qualified repair work to extend the safe use of equipment.
Performance Gain: Optimization and improvement of operational performance during refurbishment.
Dismantling and Relocation
Our teams manage the structured dismantling of end-of-life or replacement equipment, as well as their relocation when required. Each intervention is carried out in a safe, planned, and controlled manner.
Structured Dismantling: Methodical and safe disassembly of end-of-life or replacement equipment.
Complete Relocation: Planned logistics and transport to move your equipment to its new site.
Control & Safety: Fully coordinated and controlled operations to minimize risks and downtime.
Fabrication of Components and Accessories
We manufacture all complementary elements such as nozzles, flanges, manways, as well as supports and anchors. Each component is designed to ensure perfect compatibility with the main equipment and facilitate operation and maintenance.
Custom Accessories: Fabrication of nozzles, flanges, manways, supports, and adapted anchors.
Perfect Compatibility: Custom design to integrate harmoniously with the main equipment.
Easier Maintenance: Components designed to simplify access, operation, and periodic inspections.
Certified Welding and Assembly
Our teams apply qualified welding procedures to ensure assembly integrity. The processes used guarantee leak-tightness, mechanical strength, and compliance with industrial standards.
Qualified Processes: Application of approved welding methods for all types of metals and alloys.
Guaranteed Leak-Tightness: Strict controls to ensure leak-tight assemblies under high pressure or atmospheric conditions.
Mechanical Strength: Penetration and finish quality guaranteeing long-term strength under stresses.
Quality Control and Inspection
Each equipment is subjected to rigorous controls, including visual inspections, radiography, ultrasonic, and other non-destructive testing (NDT). Our objective is to ensure regulatory compliance and long-term reliability.
Rigorous Inspections: Systematic controls at each stage of fabrication by our qualified inspectors.
Non-Destructive Testing: Use of radiography, ultrasonic, and advanced visual inspections (NDT).
Assured Compliance: Guarantee of compliance with current regulations and obtaining required approvals.
Surface Treatment and Finish
We perform surface preparation as well as the application of suitable industrial coatings such as epoxy industrial paint, corrosion protection, and other specialized treatments. These steps ensure the durability of the equipment in demanding environments.
