316Ti Stainless Steel Pipe To Europe - Supplied by KCM SPECIAL STEEL for Low-Pressure Air Transport in a European Sewage Treatment Plant Customer Case Study:
——A Cost-Effective, Corrosion-Resistant Solution Compliant with EN 1.4571 Standards.
316Ti Stainless Steel Pipe to European Project Overview
A European municipal sewage treatment plant required a reliable, low-maintenance piping system for its low-pressure air network (≤2 bar gauge pressure). Existing carbon steel pipes deteriorated rapidly due to moisture, chlorides, and hydrogen sulfide (H₂S), causing frequent leaks and operational downtime. KCM SPECIAL STEEL, a leading 316Ti stainless steel pipe manufacturer and supplier, delivered EN 1.4571 (1.4571 stainless steel pipe) solutions with 2% density optimization, ensuring superior corrosion resistance and lifecycle cost savings.
Comparison of Corroded Carbon Steel vs. New 316Ti Stainless Steel Pipes
| Parameter | Carbon Steel Pipes | 316Ti Stainless Steel Pipes |
|---|---|---|
| Corrosion Resistance | Severe pitting and uniform corrosion in moist, chloride-rich, and H₂S environments. | Excellent resistance to pitting, crevice, and stress corrosion cracking (SCC). |
| Material Composition | Primarily iron (Fe) with trace carbon (C) and manganese (Mn). | Fe-Cr-Ni-Mo alloy stabilized with titanium (Ti ≥0.5%) to prevent sensitization during welding. |
| Service Environment | Unsuitable for pH <6 or >8, chloride >50 ppm, or H₂S exposure. | Stable in pH 2–12, chloride-rich (≤5,000 ppm), and H₂S-containing environments. |
| Lifespan | 3–5 years in aggressive sewage treatment conditions. | >30 years with minimal degradation under similar conditions. |
| Maintenance Costs | High (€20,000–€50,000/year for repairs and replacements). | Negligible (€0/year after installation; 25–30% lower lifecycle costs). |
| Third-Party Certification | Limited compliance; frequent leaks reported. | Passed PMI, hydrostatic testing (15 bar), and dimensional checks per EN 1.4571 standards. |
| Sustainability | Non-recyclable due to heavy corrosion; high carbon footprint. | 100% recyclable; aligns with EU Green Deal circular economy goals. |
