First In Service OÜ maintains the highest international certifications for quality, welding, structural steel, environmental management, and pressure equipment manufacturing. These certifications are independently audited and renewed regularly.
Systematic quality management across all operations. Our quality management system ensures consistent product quality, customer satisfaction monitoring, and continuous improvement throughout every manufacturing process, from initial design review through final inspection and delivery.
Certified environmental management system minimising the impact of our manufacturing operations. Active programmes for waste reduction, chemical safety, emissions control, and efficient use of natural resources across our 18,000 m² production facility.
Comprehensive quality requirements for fusion welding of metallic materials. This certification covers our complete welding operations including processes 135/136 (MIG/MAG), TIG, and SAW with penetration welding capability up to 100 mm. Our welders are individually qualified and regularly re-certified. Materials covered include carbon steel, stainless steel, duplex, super duplex, titanium, Inconel, and Hastelloy.
Execution of steel structures and aluminium components to European structural standards. This certification qualifies us to manufacture load-bearing structural components for construction, industrial, and infrastructure applications with full documentation and traceability.
EU conformity assessment for pressure equipment and components. We manufacture pressure vessels, piping, and pressure-bearing components with complete PED documentation packages including material certificates, welding procedure specifications (WPS), welder qualifications, NDT reports, and pressure test certificates.
Operating to the highest international standards.
Procurement teams increasingly search by standard rather than by service, because the standard is what the audit checks. Here is what each of ours covers and what it changes in the documentation you receive.
Unsure which standards your scope requires? Send the drawing and an engineer will tell you what applies and what it costs.
ISO 9001 (quality management), ISO 14001 (environmental management), EN 3834-2 (welding quality), EN 1090-2 (structural steel execution), and PED 2014/68/EU (pressure equipment).
Comprehensive quality requirements for fusion welding of metallic materials — the highest of the three EN 3834 levels, covering welding procedures, personnel qualification, and process control.
Execution of steel structures and aluminium structures — the technical requirements for structural steelwork placed on the European market.
Yes. Pressure equipment is manufactured to PED 2014/68/EU, with the conformity assessment route defined by the equipment category.
Non-destructive testing (VT, PT, MT, UT) is performed by certified partners — independent verification of every critical weld rather than in-house self-inspection.
Yes. Certificates are published on this page with issuing bodies and validity dates, and can be checked against the certification registries directly.
