How a job runs

The same sequence on every job, from the first drawing to the data package.

  1. 01

    Consult

    Send a drawing, datasheet or a problem on site. An engineer reviews every request and confirms scope, code and schedule.

  2. 02

    Engineer

    Material selection, design calculations and drawings, with welding procedures qualified to ASME Section IX.

  3. 03

    Fabricate

    Fabricated by certified welders under our ASME quality program, with materials and procedures matched to your specification.

  4. 04

    Inspect & test

    NDE and pressure testing coordinated to the inspection plan, with material traceability and weld records kept throughout.

  5. 05

    Deliver or install

    Shipped with a complete manufacturing data package, or installed on site by our mobile crews.
