ASME code pipe welding for Louisiana's refineries, chemical plants, power stations, and industrial facilities. Carbon steel, stainless, chrome-moly, and exotic alloys. Every weld X-ray certified when required.
Louisiana's Chemical Corridor — 85 miles of refineries and chemical plants between Baton Rouge and New Orleans — is the densest concentration of industrial facilities in North America. ExxonMobil Baton Rouge, Sasol Lake Charles, Cameron LNG, and 19 petroleum refineries processing over 3 million barrels per day require world-class welding contractors.
Pipe welding pricing depends on material, diameter, wall thickness, and code requirements. Here's what real work costs in Louisiana.
| Service Type | Typical Cost Range | What's Included |
|---|---|---|
| Carbon Steel Process Piping | $35 – $75/diameter inch | Fit-up, weld, visual inspection |
| Stainless Steel Piping | $55 – $120/diameter inch | Purge welding, passivation |
| Chrome-Moly (P91, P22) | $85 – $200/diameter inch | Preheat, PWHT, RT examination |
| Orbital/Sanitary Piping | $75 – $150/joint | Automatic orbital weld, borescope inspection |
| Pipe Spool Fabrication | $500 – $5,000/spool | Shop fab, fit, weld, hydro test |
