Certified production of process tanks, jacketed reactors, and large-scale silos under the supervision of TÜV and UDT.
The construction of pressure equipment and sterile process tanks represents the highest level of engineering expertise. At IWS Group, we combine metallurgical knowledge with massive manufacturing capabilities. We weld austenitic steels (304, 316L) and advanced nickel alloys (including Hastelloy C22 / Group 43), allowing us to handle the most aggressive corrosive environments.
Every production stage is based on approved Welding Procedure Qualification Records (WPQR according to EN ISO 15614-1). We guarantee full compliance with the European Pressure Equipment Directive (PED 2014/68/EU), delivering legal equipment passports backed by rigorous Non-Destructive Testing (NDT) of weld structures and hydrostatic tests.
Visual documentation of the rigorous circumferential welding process on rotators, internal tank polishing, and the logistically safe loading of heavy-duty oversized equipment.
By choosing IWS Group, you gain solid execution competencies. We take full responsibility for the process: from isometric documentation verification to physical welding, machining, and validation under the supervision of notified bodies.
Welding production certified to the highest ISO 3834-2 standard. We hold full authorizations for the prefabrication, assembly, and modernization of pressure equipment in accordance with the stringent PED directive.
We conduct advanced 3D modeling and Finite Element Analysis (FEA). We resolve spatial clashes at the documentation level, preventing costly errors on the construction site.
We take over full logistics. We integrate our own machinery park in Poland with fully equipped, mobile assembly crews operating at sites across Europe.
We are experts in austenitic steels. We maintain 100% material traceability (3.1 certificates) strictly required during audits in the food and pharmaceutical industries.
We execute multi-million projects, delivering complete piping installations, tanks, and load-bearing structures from a single source.
