Product Description

Corrugated Metal Hoses with Braided Stainless Steel Protection

Flexible metal hoses are essential for systems handling water, steam, hot oil, and gas. Designed for high-pressure resistance and structural flexibility, these hoses are ideal for conducting liquids, compensating for installation misalignments, and absorbing vibrations or thermal expansions.

Material Specifications:

  • Hose: SS304, SS316, SS321
  • Braid: SS304
  • Connection: Galvanized steel or Stainless Steel

Frequently Asked Questions

What are the main advantages of using flexible metal hoses?
They provide high pressure and temperature resistance, absorb vibration, and compensate for thermal expansion or installation misalignments while offering a longer service life compared to rigid piping.
What size ranges are available?
Our corrugated metal hoses range from DN8 up to DN400, and can reach up to DN600 for specific industrial applications.
Can the fittings be customized for specific requirements?
Yes, we supply various fittings including nuts, adapters, and nipples with BSP, NPT, or flange connections (ANSI, DIN, JIS) tailored to your technical requirements.
Which materials are used for the hose and braiding?
The inner core is typically made of SS304, SS321, or SS316L, while the outer braid is usually high-strength SS304.
What information is needed to get an accurate quotation?
To provide the best quote, we need the technical drawings, material type, fitting type, total length, diameter, and the expected working pressure and temperature.
Are these hoses suitable for high-temperature gas applications?
Yes, the stainless steel construction allows them to operate in environments ranging from cryogenic temperatures up to 1500°F (approx. 815°C).
