Why pharma plants demand a different contractor
Pharmaceutical manufacturing operates under regulatory frameworks — US FDA, WHO GMP, EU GMP, Indian Schedule M — that impose fabrication and installation standards far beyond what general mechanical contractors deliver. A single rough weld bead inside a WFI loop creates a biofilm trap that contaminates an entire batch. A surface finish reading above Ra 0.8 microns on a reactor interior fails audit. HAIL understands that in pharmaceutical construction, the quality of the metal surface is the quality of the product. Our fabrication workshop is set up for controlled-environment SS 316L work with dedicated tooling (no carbon steel cross-contamination), calibrated surface-finish measurement, orbital welding machines for tube-to-tube and tube-to-fitting joints, and bore-scope inspection capability for every weld.

GMP fabrication standards and surface finish
Pharmaceutical equipment fabrication is governed by surface finish, weld quality and material traceability requirements that are non-negotiable during regulatory audits. HAIL's fabrication approach for pharma projects follows these standards:
| Parameter | HAIL standard | Applicable guideline |
|---|---|---|
| Material | SS 316L (UNS S31603), 2B or No. 4 finish plate/pipe | ASME BPE, ASTM A240/A312 |
| Internal surface finish (product contact) | Ra 0.4–0.8 microns (mechanical polish + electropolish) | ASME BPE SF-4 / SF-3 |
| External surface finish | Ra 0.8–1.6 microns (mechanical polish or bead-blast) | ASME BPE |
| Welding (vessels) | Full-penetration TIG, argon purge, no discolouration | ASME Section IX, ASME BPE |
| Welding (tubing) | Automatic orbital welding, bore-scope 100% | ASME BPE |
| Passivation | Citric acid or nitric acid passivation post-fabrication | ASTM A967 |
| Documentation | MTR, WPS/PQR, weld log, bore-scope report, surface finish report, passivation certificate, IQ protocol support | cGMP, ISPE |

HAIL's workshop capability for pharma fabrication
HAIL operates a 33,000 sq.ft. fabrication workshop in Vadodara — strategically located in Gujarat's pharma manufacturing corridor. For pharmaceutical projects, we maintain dedicated fabrication protocols:
- Segregated SS work area — no carbon steel fabrication in the same bay. Dedicated SS grinding discs, wire brushes and tools to prevent iron contamination.
- Orbital welding capability — automatic orbital welding machines for SS 316L tubing (1/2" to 4" OD) with programmable weld parameters, coupon-qualified per ASME BPE, and bore-scope verification of every production weld.
- Surface finish measurement — calibrated surface roughness tester for Ra measurement on polished surfaces. Pre- and post-electropolish readings documented.
- Plate rolling and forming — SS 316L plate rolling up to 25 mm thickness for vessel shells, dished ends and cones.
- PWHT and stress relief — controlled post-weld heat treatment for thick-section SS vessels per code requirements.
- Full PMI traceability — every plate, pipe, fitting and weld in SS 316L is PMI-verified with XRF analyser. Heat number traceability maintained from mill certificate through finished equipment.
