2.5" stainless steel flexible conduite pipe 1/2" exhaust piping

Our 2.5" Stainless Steel Flexible Conduit Pipe and 1/2" Exhaust Piping are premium-grade solutions engineered for demanding applications requiring flexibility, corrosion resistance, and high-temperature performance. These products combine advanced materials with precision manufacturing to ensure reliability in automotive, industrial, and architectural environments.

1. 2.5" Stainless Steel Flexible Conduit Pipe

Designed for mechanical protection and fluid/gas transfer, this flexible conduit is ideal for environments with vibration, thermal expansion, or misalignment. Constructed from 304 stainless steel (ASTM A554/EN 10088-2 compliant), it offers exceptional durability and resistance to corrosion, abrasion, and high temperatures.

Key Features:

• Material & Construction:
  • 304 Stainless Steel: Contains 18-20% chromium and 8-10.5% nickel for superior corrosion resistance in harsh environments.
  • Double-Braided Structure: Reinforced with two layers of interwoven stainless steel wires for enhanced flexibility and pressure resistance.
  • Seamless Welds: Full-penetration TIG welding ensures leak-free performance and structural integrity.
• Technical Parameters:
