Specialty Piping Services

Not all piping is equal... Specialty piping spools, including flow meter runs, welded jacketed piping systems, and alloy piping spools, can take a little extra care and attention. Principal Technology's fabrication group is experienced in meeting these challenges.

Our fabricators and welders have the experience and credentials to tackle almost any specialty piping system. Stainless steel, piping meter runs, and jacketed piping are just a few of the projects in our portfolio.

Fabricating specialty piping systems goes beyond just “cut, fit, and weld” our team has developed the processes and techniques to fabricate even the most complex specialty and jacketed piping spools.

Our welders are qualified in ASME Section IX and AWS D1.1 and D1.6 using SMAW, GTAW, GMAW, FCAW process, 6G positions, for piping to 24″ NPS, and metal thickness up to 1″. We are ready to tackle the most challenging pipe fabrication project.

our work

stainless steel pipeline valve risers

Stainless Steel Pipeline Valve Risers

Our shop fabricated multiple 10″ and 12″ pipeline valve risers for a client in West Texas.   This project included the SS pipe fabrication, preassembly, and pressure testing of the bolted assemblies before shipping them West.

steam jacketed molten sulfur piping system

Steam Jacketed Molten Sulfur Piping System

Our fabrication group built this modular molten sulfur rundown skid in our Plano, Texas shop.   The jacketed piping was installed on a small structural steel skid complete with sulfur seals, steam and condensate manifolds, tubing, and insulation before shipping it to our client’s sulfur recovery unit expansion project.
