Industries we serve

Every industry has its own framework of standards, its own inspection regime and its own pitfalls. A steel fabricator works to EN 1090 and its execution classes, a pressure equipment manufacturer to the PED and EN 13445, and a shipyard to a classification society. DEHAAS knows these frameworks from the inside and translates them into workable procedures, quality plans and inspection agreements.

Select your industry below for the requirements that apply, the documents you must be able to produce and how we support you.

Steel construction

EN 1090 support for steel fabricators: execution classes, FPC, procedure book, welding coordinator and CE marking, by DEHAAS.

Machine building

Welding engineering for machine builders: choosing the weld quality level, fatigue loading, dimensional stability, ISO 3834 and qualifications that cover the range.

Offshore and marine

Offshore welding under DNV, Lloyd's and NORSOK: qualification, CTOD testing, sour service and third party inspection at the yard.

Petrochemical and process industry

Piping and equipment in the process industry: ASME B31.3, PED, PMI, sour service and inspection during turnarounds.

Pressure equipment

PED 2014/68/EU, EN 13445 and AD 2000: procedure qualification by a notified body, conformity assessment modules and the MRB for pressure equipment.

Tank fabrication

Building and inspecting storage tanks to EN 14015, API 650 and BRL K903: welding procedures, bottom seams, leak testing and inspection during erection.

Hydrogen and the energy transition

Hydrogen piping, electrolysers and storage: hydrogen embrittlement, material selection, ASME B31.12 and what it all demands from the welding.

Shipbuilding

Shipbuilding under class: approval of welding procedures by the classification society, shipbuilding steel, distortion control and inspection at the yard.

Cranes and lifting equipment

Crane building and lifting gear: fatigue loading, EN 13001, weld quality level per joint, inspection of lifting lugs and repair of existing structures.

Food and pharmaceutical

Hygienic piping and equipment: orbital welding, EHEDG, surface roughness, backing gas and documentation of every weld.
