Process Piping and Fabrication

 Process piping is the mainstay of DUBOIS Sheet Metal Works, LLC. Specifications which vary from company to company and combining ASME B31.3 rules with these specifications make this type of fabrication very demanding. DUBOIS meets this demand by having knowledgeable journeyman pipefitters and  certified welders on staff.  We maintain an AWS Certified Welding Inspector on staff to compliment our quality control system which ensures that the project we build is right the first time. 

 DUBOIS will meet all NDE, PWHT and Painting requirements.  We maintain our own delivery equipment plus contracts with several outside shipping companies to ensure delivery to you on your delivery date.  

 DUBOIS can fabricate from the most exotic alloys, including nickels, Duplex and 300/400 Stainless, and all standard Chrome Alloys.
