Our Process


Engineering /

At ASI, we are your project team — we form long-term relationships with our clients, often becoming their supplier of choice for all custom equipment applications. Our clients utilize our experience and expertise in multiple disciplines; from project management, application engineering, electrical engineering, PLC programming, CAD services, and 3D modeling. We work with you to size the system components in accordance with process application conditions (flow, pressure, temperature). We review the compatibility of materials with the process fluid, ensuring the right materials are selected for your application.


Manufacturing / Fabrication

After client approval of the drawings and documents, the project kicks-off with our experienced team of fabricators.  Code-certified welders, fabricators, electricians, and panel builders turn concepts into impeccable reality.  With in-process QC inspections throughout the fabrication stage, you can ensure that your custom-engineered system will be built in strict accordance with all drawings and industry standards.


Quality Assurance /

Our ultimate goal is dispatching “zero defect” projects from our facility. To ensure this, all fabricated equipment undergoes a strict course of quality control inspections including:

  • visual & dimensional checks
  • electrical continuity tests
  • hydrostatic leak testing
  • and full equipment functional testing.

Non-destructive examination (NDE) can also be provided in accordance with project requirements from:

  • positive material identification (PMI)
  • liquid penetrant testing (LP)
  • ultrasonic thickness testing (UT)
  • and radiographic examination (RT).

After completion and acceptance of all testing, the Client is provided with an equipment dossier, which includes:

  • material certifications
  • calibration certificates
  • test result documentation
  • component data sheets & manuals
  • and equipment photographs.
