The Technical Challenge: Mitigating the Risk of Contamination & Failure

For engineers in the Food, Beverage, and Pharmaceutical sectors, procuring sanitary equipment is an exercise in managing catastrophic risk. Failure can lead to product recalls and brand destruction, making it critical to prevent contamination and ensure equipment integrity through expert fabrication and documentation.

Microbial Contamination

Fabrication flaws like microscopic crevices, poor welds, or improper surface finishes create breeding grounds for bacteria. This can lead to the growth of resilient biofilms that standard cleaning (CIP) cycles cannot remove, creating a major contamination risk.

Material Degradation

Aggressive cleaning agents can cause corrosion and pitting on incorrect alloys, which compromises the hygienic surface and leads to premature equipment failure. This risk increases when fabricators lack material selection expertise.

The Audit & Documentation Gauntlet

Without meticulous, verifiable documentation from a fabricator (like MTRs and weld maps), companies face failed regulatory audits and costly production delays. Buyers require this documented proof of compliance to operate safely.

Our Solution: Verifiable Quality & Fabrication Discipline

We directly address sanitary challenges by blending old-world craftsmanship with modern technology and a disciplined, ISO 9001:2015 certified quality system. Our approach provides the verifiable assurance required for the most demanding applications.

  • Welding & Fabrication Mastery: Our AWS and ASME-certified welders use the gold-standard GTAW/TIG process for sanitary applications. For high-purity needs, we use automated orbital welding and perform borescope inspections to ensure every product-contact weld has 100% penetration and a flawless, crevice-free surface.
  • Material Expertise & Surface Treatment: While masters of 304L and 316L stainless steel, we also guide clients on when to upgrade to superior alloys like AL-6XN or Hastelloy to combat corrosion. After fabrication, we perform meticulous pickling and passivation to maximize corrosion resistance and ensure a truly hygienic surface.
  • Guaranteed Proof & Documentation: Most importantly, we deliver proof. Every project comes with a comprehensive turnover package, including MTRs for full material traceability, weld maps, surface finish (Ra) reports, and passivation certificates. This gives our clients the audit-ready assurance they need to operate with confidence.

Examples of Fabricated Sanitary Equipment

Our capabilities in sanitary fabrication cover a wide range of custom equipment, designed to meet the strictest standards for purity and cleanability.

Mixing Tanks, Vessels, and Bioreactors

Custom-fabricated containers engineered with smooth, crevice-free surfaces for hygienic mixing, holding, or cultivating sensitive biological products.

Skid-Mounted Process Systems (e.g., CIP Skids)

Fully integrated, pre-assembled modules on a portable frame, such as Clean-in-Place (CIP) systems, designed for easy installation and validated performance.

Hygienic Conveyors and Augers

Material handling equipment, like screw conveyors, designed and built with cleanability in mind to safely transport bulk solids while preventing contamination.

Sanitary Process Piping, Tubing, and Valve Manifolds

The essential plumbing of a hygienic system, including orbital-welded pipes and complex valve clusters, engineered for sterile fluid transfer and zero contamination.

Key Industries for Sanitary Fabrication

The principles of hygienic design and sanitary fabrication are critical in any industry where product purity and safety are non-negotiable. We provide expert solutions for:

  • Food & Beverage
  • Pharmaceutical & Biotechnology
  • Water & Wastewater
  • Cosmetics & Personal Care
  • Power, Energy & Chemical

Frequently Asked Questions

Sanitary fabrication is focused on hygienic design for microbiological cleanability. This requires specific techniques not found in standard fabrication, including crevice-free welds, certified surface finishes (Ra), fully drainable designs, and complete material traceability (MTRs).

Every project includes a comprehensive turnover package for your validation and compliance needs. It contains Material Test Reports (MTRs), weld maps, and certificates for surface finish and passivation, ensuring a fully auditable product.

Use 316L for most standard applications. Upgrade to a higher alloy like AL-6XN when your process or cleaning chemicals involve high concentrations of chlorides. The superior alloy is necessary to prevent pitting and crevice corrosion, which mitigates long-term contamination risk.
