Application and reasons for selection of 04/316L stainless steel pipes and fittings in the municipal field
Application Scenarios in Municipal Field
304 Stainless Steel Pipes & Fittings: Municipal water supply network (main pipes, distribution pipes), secondary water supply facility renovation, fire-fighting pipelines in general areas (e.g., water mist fire suppression systems), siphonic roof rainwater drainage systems, water supply branches in urban underground utility tunnels.
316L Stainless Steel Pipes & Fittings: Municipal pipe networks in coastal areas (salt fog corrosion resistance), pipelines for conveying corrosive media in sewage treatment plants, supporting pipelines for seawater desalination, gas transmission pipelines (low-pressure distribution networks), municipal auxiliary pipelines around chemical parks.
Application of 04/316L stainless steel pipes and fittings in the municipal field
Core Reasons for Selection
1. Excellent Corrosion Resistance: 304 contains chromium to form a dense oxide film, resisting chloride ion erosion in tap water; 316L adds molybdenum to enhance acid-alkali and stress corrosion resistance, adapting to complex municipal environments.
2. Hygienic & Safe: Smooth inner wall with no impurity precipitation, antibacterial rate over 99%, complying with WHO drinking water standards, eliminating secondary pollution and ensuring domestic water safety.
3. Long Service Life & Low Maintenance: Service life of 50-70 years, far exceeding traditional pipes, reducing pipe network renovation frequency, lowering life-cycle costs, and meeting the needs of century-old municipal projects.
4. High Strength for Working Conditions: High tensile strength, able to withstand high pressure and geological settlement impact, adapting to complex municipal construction conditions; crimp connection is convenient and efficient, improving construction efficiency.
5. Green & Sustainable: 100% recyclable, no release of toxic and harmful substances, complying with the "dual carbon" goal and green municipal construction requirements.
