Certified ASME BPE Metallurgy & Sanitary Skid Construction
To guarantee pyrogen-free water and steam, all contact surfaces conform strictly to ASME BPE standards and international pharmacopeias:
AISI 316L (EN 1.4435) Contact
Column tubes, condenser shells, and distribution headers fabricated strictly from low-carbon AISI 316L (EN 1.4435) with controlled delta ferrite content (< 1%).
Ra ≤ 0.4 μm Mirror Electropolish
All contact surfaces electro-polished to mirror finish Ra ≤ 0.4 μm (15 μ-in) to eliminate microscopic biofilm adhesion and rouging vulnerability.
Orbital TIG & Boroscopy
Automatic closed-head orbital TIG welding under 99.999% argon purge, backed by 100% video boroscopic weld inspection recordings and weld logs.
Continuous 80°C Loop & Valves
Zero dead-leg sanitary diaphragm valves (ASME BPE L/D < 2) with continuous hot recirculation (>80°C) ensuring self-sanitizing pyrogen-free operation.
BTI Direct Factory Indenting vs. Traditional Local Stockists
Comparing BTI's direct manufacturer indenting model against local water treatment assemblers and dealers.
| Evaluation Parameter | BTI Factory Direct Indenting | Traditional Local Stockists |
|---|---|---|
| 1. Capital Expenditure (Capex) | Direct Ex-Works (EXW) OEM price eliminating middleman markups (30%–50% savings) | Heavily marked up by domestic vendors with high commercial intermediary fees |
| 2. Custom Engineering & Tooling | Custom engineered column number (3–6 effects), tailored steam pressure, and loop capacity | Standard off-the-shelf single column boiler units unsuitable for high-capacity WFI |
| 3. Metallurgy & Sanitary Finish | Certified AISI 316L (EN 1.4435) with electro-polish Ra ≤ 0.4 μm, DTS heat exchangers | Single-tube-sheet designs with non-certified SS 304 causing cross-contamination |
| 4. Pre-Shipment Inspection (FAT) | Hydrostatic pressure test (1.5x working pressure), helium leak check, and live steam run | No pre-shipment testing; units assembled locally from unverified imported components |
| 5. Regulatory Compliance (DRAP / cGMP) | Complete turnkey DQ, IQ, OQ, PQ dossiers, TOC/conductivity logs, and passivation certificates | Generic pump manuals only; fails DRAP injectable licensing requirements |
| 6. Local SAT & Engineering Accountability | Full on-site SAT by certified local field engineers and OEM technical staff | Drop-off delivery only; plant owner left to hire local non-sanitary plumbing contractors |
