Engineering Knowledge Base

Frequently Asked Technical Questions

What is the operational advantage of automated orbital welding over manual sanitary TIG?

Manual TIG welding relies on human hand speed and torch angle, which can result in inconsistent internal weld penetration, micro-crevices, and excess heat-tint oxidation. Automated closed-chamber orbital welding regulates current, pulse frequency, and travel speed with computerized precision. Under continuous argon purge (< 20 ppm O2), it delivers a perfectly flush, crevice-free internal weld bead that resists bacterial biofilm formation and ensures 100% cleanability during CIP sanitization.

Why does MBH strictly control sulfur content between 0.005% and 0.017% in sanitary 316L tubing?

Sulfur acts as a surface-active element in the molten weld pool. If sulfur is below 0.005%, Marangoni fluid flow causes the molten metal to spread outward, resulting in wide, shallow penetration. If sulfur exceeds 0.017%, fluid flows deeply downward, causing burn-through. Controlling sulfur tightly between 0.005% and 0.017% guarantees symmetrical, uniform weld pool penetration across all orbital joints.

How does modular off-site skid fabrication reduce overall CAPEX and installation downtime?

Building process equipment on an active plant floor requires hot-work permits, dust containment tents, temporary scaffolding, and prolonged plant shutdowns costing tens of thousands of dollars per day. With modular skid fabrication, 80% of assembly occurs in our clean facility while your plant continues running. The completed skid arrives pre-piped, pre-wired, and wet-tested. On-site installation is reduced to rigging into position, bolting down, and connecting primary utility tie-ins during a single 48-to-72-hour weekend shutdown.

What surface finish standards are maintained for food, beverage, and dairy contact?

For food, dairy, and beverage applications, internal surfaces receive uniform sanitary mechanical polishing and thorough passivation to eliminate crevices where residues can anchor, ensuring complete cleanability during CIP sanitization cycles without making unrealistic sub-micron claims.

How do you verify that Clean-in-Place (CIP) spray balls cover 100% of internal vessel surfaces?

We conduct a Riboflavin Spray Coverage Test compliant with EHEDG guidelines. The vessel interior is completely coated with a fluorescent riboflavin solution and inspected under UV blacklight. The automated CIP cycle is initiated for a timed wash. Post-wash UV inspection verifies that 100% of the riboflavin has been dissolved and removed, proving that there are zero spray shadows or blind spots behind agitator shafts and baffles.

What documents are included in the Turnover Package (TOP) for multinational audits?

Every project is accompanied by an audit-ready Turnover Package containing EN 10204 3.1 Mill Test Reports (chemical & mechanical properties), Welder Qualifications (WPQ/WPS), 3D isometric weld identification maps, digital video boroscopy recordings of internal joints, certified hydrostatic test chart logs, dimensional inspection sheets verifying 1 µm tolerance, and ASTM A967 Passivation Certificates.

MBH SOLUTIONS · MISSION STATEMENT
“To deliver end-to-end engineering solutions — spanning process systems, industrial automation, and mechanical fabrication — that enable manufacturers to build, modernise, and optimise their production operations with confidence, quality, and long-term reliability.”

The Single-Source Advantage: Mechanical Fabrication + Siemens Automation

Conventional projects require managing separate mechanical vessel builders and control system software integrators, leading to vendor finger-pointing during line commissioning. MBH Solutions fabricates the physical vessels, orbital piping skids, and conveyor lines while our in-house Siemens automation team programs the S7 PLCs, WinCC SCADA dashboards, and control panels under a single turnkey contract.
