Flexible Metal Hose for Pipeline Vibration Absorption & Compensation
Stainless steel flexible metal hose is a high‑performance industrial pipeline accessory composed of corrugated tube body and stainless steel braided reinforcement layer. It solves pipeline problems such as rigid connection stress, vibration transmission, thermal expansion and installation deviation. Featuring excellent pressure resistance, temperature resistance and corrosion resistance, it is widely used in petroleum, chemical, power, metallurgy, heating, water treatment and mechanical equipment piping systems. Custom sizes and end fittings are available for different working conditions.
1. Product Structure & Material Features
The metal hose adopts three‑layer structure: inner corrugated tube, stainless steel braided reinforcement layer and metal end fitting. Main materials are 304 and 316L stainless steel; 321 is optional for high‑temperature conditions. Inner corrugated tube provides good flexibility and telescopic performance. Dense wire braided layer improves pressure capacity and structural stability. Integral welding avoids leakage and fracture risks. Raw materials have stable chemical properties for long‑time continuous operation.
2. Core Product Advantages
It delivers outstanding vibration absorption and noise reduction to prevent pipeline resonance damage. It compensates displacement caused by thermal expansion‑contraction and installation misalignment to release pipeline stress. It performs well under high‑temperature, high‑pressure and corrosive harsh environments. Multiple connection types and customizable lengths simplify field installation and cut maintenance cost. Integral welding ensures zero‑leakage and good fatigue resistance for long‑cycle service.
