Frequently asked questions
Do you work to ASME B31.3 and ASME IX?
Yes. We prefabricate and install process piping to ASME B31.3, with procedures and welders qualified to ASME IX or ISO 9606-1, as the project requires.
Are you ISO 3834 or ISO 9001 certified?
We do not declare any company certifications. We apply the quality requirements set by each project and hand over the dossier with procedures, qualifications, inspections and traceability.
Do you do laser alignment of pumps and motors?
Yes. We align rotating equipment with laser or dial indicators, to the manufacturer's tolerances or API 686, and issue the report.
Do you work outside Spain?
Yes. We are based in Madrid with international coverage: Europe, the Americas, the Middle East, Africa, Asia and Oceania.
How quickly can you send a quote?
With drawings or isometrics, we send an itemised technical quote within 24 to 48 hours.
