Pipe Fabrication Shop


When you need quality prefabricated piping delivered on time and to specification, rely on Ahern’s proven track record of success. All pipe spools must pass the stringent quality control audits of our highly trained and experienced QC professionals before leaving the pipe fabrication shop. We offer a wide range of capabilities from project management to drafting and material control. To discuss your prefabricated industrial piping needs, contact our experts.


Since 2012, our ASME Certified Welders have completed over 209,000 x-ray views with an average passing rate of 97.6%.

The workmanship that has been done is of high quality. It shows the degree of planning that went into the assembly of the modules, and each looks to be very good replicas of one another.

Quality ControlProcess



Ahern has provided piping systems to 49 U.S. states and 8 international countries.

Ahern was willing to work with us during the bid process using very little information to develop a budget price. Plus, we were comfortable with the size of Ahern's pipe fabrication shop to accommodate a project of this magnitude.
