FAQ

Flange-Connected Stainless Steel Braided Metal Hose

Q1: What flange standards do you support?
A1: We offer ANSI B16.5, DIN 2501, JIS B2220, and GB/T 9119 standards. Custom flange dimensions are available upon request.

Q2: What's the maximum working pressure and temperature range?
A2: Max working pressure up to 40MPa (Class2500); Temperature range: -200℃ ~ 600℃ (cryogenic/high-temperature options available).

Q3: Can this hose be used for corrosive media like seawater or chemicals?
A3: Yes. Standard 316L stainless steel resists most acids/alkalis; Hastelloy/duplex steel options are recommended for extreme corrosion (e.g., seawater, strong acids).

Q4: What's the maximum diameter and length you can provide?
A4: Diameter range: DN50 ~ DN700 (2" ~ 28"); Length: 300mm ~ 10m+ (custom cut-to-length service available).

Q5: How does it compensate for pipeline displacement?
A5: The corrugated inner tube + multi-layer braid design absorbs axial/lateral angular displacement (max compensation: 10% of pipe diameter) and reduces vibration impact.

Q6: What certifications do you offer for export?
A6: ISO 9001, CE (CPR), ASME B31.3, DNV GL.Custom certifications can be provided.

Q7: What's the warranty period and quality control process?
A7: 12-month warranty. All hoses undergo 1.5× working pressure testing, leak detection, and corrosion resistance inspection before shipment.

Q8: What's the lead time for bulk orders and how are they packaged?
A8: Lead time: 7-15 working days (bulk); 3-5 days (samples). Packaging: Export wooden case + PE film + anti-rust oil (moisture-proof and shock-proof).
