1/4-12" SS304 316 Corrugated Stainless Steel Braided Flexible Metal Hoses for Chemical Industry

Product Description

Corrugated metal hose

Corrugated metal hose is a critical flexible component in modern industrial pipeline systems, defined by its thin-walled, wave-shaped tube structure. Composed of three core parts—corrugated tube (the flexible main body), braid sleeve (for pressure reinforcement and abrasion protection), and fittings (for stable connections)—it balances flexibility, durability, and performance.

Typically crafted from 304/316 stainless steel (or 321 for high-temperature use), this hose boasts exceptional corrosion resistance (ideal for chemical, marine, and food-grade applications) and a broad temperature range of -196°C to 600°C, handling both cryogenic media and high-temperature steam. Its small minimum bending radius (3–5 times its outer diameter) allows seamless installation in tight spaces, while single/double braid sleeves enable working pressures from 0.6MPa to 32MPa (custom models reach 42MPa).

Beyond media transfer, it excels at absorbing pipeline displacement (from thermal expansion or building settlement) and isolating equipment vibration (e.g., pumps, compressors). This versatility makes it a staple in industries like chemical processing, power generation, construction HVAC, automotive manufacturing, and marine engineering—delivering reliable performance in complex operating environments.
