Products Description
This series of flanged metal hoses is precisely corrugated and formed of 304/316 high-quality stainless steel, with regular and tough corrugations, excellent fatigue resistance and stable performance under repeated bending, stretching and long-term high-frequency vibration. The smooth inner wall reduces fluid resistance and prevents scaling and blockage to ensure stable medium transmission. Both-end flanges adopt forged integral welding technology with flat surfaces, high verticality and accurate bolt holes for tight fitting and uniform stress. The dense and full welds greatly enhance overall structural strength, enabling long-term resistance to alternating temperature, high-pressure pulse and medium corrosion. Featuring convenient assembly and disassembly with high installation tolerance, the flanged structure meets the flexible buffering needs of rigid connection for large equipment, fixed pipelines and heavy-duty projects. Custom non-standard caliber, pressure and flange specifications are available with strong universality and adaptability.
Product Advantages
High-pressure Flange Sealing & Zero Leakage
Adopting flat flange docking structure with large and uniform sealing contact area and high-quality gaskets, the hose avoids loosening and medium leakage under high pressure. Compared with traditional threaded joints, it completely eliminates leakage and thread slipping risks under high-pressure and large-flow conditions, delivering stronger sealing stability for long-term operation of heavy-duty industrial pipelines.
Tough Vibration & Displacement Compensation
The flexible stainless steel corrugated body effectively absorbs high-frequency vibration from pumps and units, buffers fluid pulse pressure and reduces pipeline noise. It accurately compensates for pipeline thermal expansion and contraction, foundation settlement and installation misalignment, avoiding stress concentration, cracking and equipment loosening of rigid pipelines to fully protect the pipeline system.
Corrosion & Weather Resistance for Wide Applications
304/316 stainless steel features excellent rust prevention, acid and alkali resistance, temperature resistance and aging resistance, resisting long-term scouring of steam, oil, water and weak corrosive chemical media. It adapts to complex and harsh conditions such as indoor heavy equipment, outdoor open-air pipelines, humid salt fog and alternating cold and heat, with a far longer service life than ordinary pipe fittings.
Easy Installation & High Tolerance
With accurate bolt holes and high universality, flanges enable simple alignment and easy assembly and maintenance without precise thread matching. It adapts well to on-site pipeline deviation, equipment displacement and limited installation space, greatly reducing engineering installation and later maintenance costs.
Stable Explosion-proof & Pressure-resistant Structure
With precise corrugated structure, uniform wall thickness, integrally forged flanges and full welding technology, the hose has high structural strength with strong deformation and burst resistance. It stably withstands industrial high pressure and fluid impact without bulging, cracking or welding detachment during long-term continuous industrial operation.

Product Q&A
Q: What are the advantages of flanged metal hoses over threaded metal hoses?
A: Flanged type adopts large-area flat sealing with higher pressure resistance and more stable sealing performance, suitable for high-pressure, large-flow and heavy-duty industrial conditions; threaded type has small sealing area and only adapts to conventional low-pressure conditions. Flanged metal hoses feature uniform stress, vibration resistance, no loose leakage and convenient maintenance, with far better service life and operational safety than ordinary threaded metal hoses.
Q: Are flanged metal hoses suitable for high-pressure steam conditions?
A: Yes. With high-temperature resistant stainless steel body and integrally welded flange structure, the hose has excellent temperature and pressure resistance, suitable for high-pressure steam transmission, boiler pipelines and high-temperature thermal pipelines. It provides reliable thermal deformation compensation to solve thermal stretching and vibration leakage problems of high-temperature pipelines.
Q: Can flange specifications be customized?
A: Full non-standard customization is available. We can customize products with different flange standards, hole distances, pressure levels and pipe lengths according to customer drawings, equipment interface standards and on-site conditions, compatible with GB, ANSI, DIN and other standards to meet differentiated assembly needs of different countries and projects.
