Mechanical Services FAQ

Common questions regarding our welding credentials, site capabilities, and turnaround support.

Are your welders certified for high-pressure ASME piping?

Yes, all our welders and welding operators hold ASME Section IX certifications across SMAW, GTAW (TIG), FCAW, and GMAW processes for Carbon Steel, Alloy Steel, Stainless Steel, and Duplex materials.

Do you handle both shop fabrication and field installation?

Absolutely. We operate a fully equipped fabrication workshop for structural and pipe spooling work, while fielding experienced rigging and erection crews for seamless site installation.

What precision alignment tools do you deploy for rotating machinery?

We utilize dual-laser shaft alignment systems with thermal growth compensation, capable of achieving angular and parallel offsets under 0.01mm to drastically extend seal and bearing lifespans.
