AZCO has 83,000 square feet of enclosed shop space dedicated to carbon steel, stainless steel, chrome-moly, and exotic alloy pipe and metal fabrication.

Our fabricated spools are inspected to ensure accuracy, weld quality, and conformance to the design and specifications of each customer or per code requirements. The finished product then undergoes testing as specified by the customer per code. Non-destructive examination (NDE) including positive material identification (PMI), magnetic particle, dye penetrant, hydro, ultrasound, and radiographic testing can all be performed at our facilities. To ensure our customers the finest welded product, our quality control personnel are Certified Welding Inspectors in accordance with AWS QC1.
