Adjustable 3 4 Flex Conduit Metal Tube High Pressure Multi Layer Steel Braid Burst Safety

Adjustable Metal Tube High Pressure Multi Layer Steel Braid Burst Safety

Description

Designed for vibration damping and thermal expansion compensation, our flexible metal hose features precision-welded convolutions with low springback force, allowing tight-radius bending (3x OD) without kinking. The electropolished inner surface (Ra ≤ 0.8µm) ensures zero contamination for semiconductor, pharmaceutical, and ultra-high-purity (UHP) gas systems.

Specifications

Key Features

► Electropolished Interior: Ra ≤ 0.4μm surface finish prevents particulate adhesion (SEMI F57 compliant)

► Galvanic Isolation: Dielectric breaks prevent electrolytic corrosion in mixed-metal systems

► Abrasion-Resistant Liners: Alumina ceramic (90% Al₂O₃) or tungsten carbide coatings for slurry applications

► Chemical Compatibility: Resists 98% sulfuric acid (20°C) and 50% NaOH (93°C) per ASTM G31 testing

Applications

► Petrochemical refining

► Offshore oil gas production

► Slurry abrasive media handling

► Exhaust gas systems
