FAQ

FAQ for Threaded Stainless Steel Braided Metal Hose

Q1: What's the maximum customizable diameter and length?
A1: The maximum diameter is DN1200 (48"), and the length can be customized up to 50m. Standard range covers DN50~DN1200, with cut-to-length service available.

Q2: Which flange standards do you support for customization?
A2: We offer ANSI (B16.5), DN (GB/T 9119), JIS, and ASME standards. Non-standard flange dimensions are also acceptable with provided drawings.

Q3: What material options are available, and how to choose?
A3: Options include 304/316L stainless steel (general corrosion), duplex steel (seawater/high chlorine media), and Hastelloy (extreme corrosion/high temp). We recommend materials based on your medium, pressure, and temperature.

Q4: What's the working pressure and temperature range?
A4: Working pressure reaches up to 42MPa (with multi-layer braiding); temperature range is -270℃~1000℃. Specific parameters can be tailored to your operating conditions.

Q5: How long is the lead time for custom orders?
A5: For standard specifications (DN50~DN500), lead time is 15~25 days; for large-diameter (DN600+) or special materials , it's 30~45 days.

Q6: Do you provide quality testing and certifications?
A6: Yes. Each hose undergoes 1.5× working pressure hydrostatic testing and helium leak detection. Certifications like ISO 9001, CE, and ATEX are available.

Q7: Can it be used for high-temperature steam or corrosive chemicals?
A7: Absolutely. 316L/duplex steel models suit corrosive media (acids, seawater), while Hastelloy models handle high-temperature steam (up to 1000℃) and harsh chemicals.

Q8: What's the MOQ and packaging for custom orders?
A8: MOQ is 1 unit for standard materials. Packaging uses moisture-proof PE bags + export cartons with wooden frames for large-diameter products to prevent damage during shipping.
