High Pressure Hose | Flexible Connection Core Component for Gas Fire Suppression Systems

High Pressure Hose | Flexible Connection Core Component for Gas Fire Suppression Systems

Product Overview

The high pressure hose is installed between the container valve of the agent storage cylinder and the liquid check valve on the manifold. Its main function is to safely and smoothly convey the extinguishing agent released from the cylinder to the manifold, while using its flexible structure to buffer the high-pressure impact during system activation, making cylinder installation, removal, and maintenance easier. Xingjin high pressure hoses feature a composite structure of stainless steel corrugated tube and stainless steel wire braid, offering strong pressure-bearing capacity, suitable for various piped fire suppression systems, meeting the high safety requirements of commercial and industrial facilities.


Applicable Places

Xingjin high pressure hoses are widely used in the following commercial and industrial applications:

  • Data Centers & Server Rooms – Long-term system reliability requires excellent fatigue resistance

  • Power Distribution & Transformer Rooms – Compact spaces benefit from flexible hose design for easy installation

  • Telecom Base Stations & 5G Rooms – Unattended sites require long-term stability and leak-free performance

  • Generator Rooms & Oil Storage Areas – High-risk areas require corrosion-resistant hoses for smooth agent delivery

  • Industrial & Chemical Plants – Multiple cylinder systems require individual hose connections as standard components

  • Libraries, Archives & Valuable Storage – High-reliability systems rely on hoses as core connection components

Installation & Maintenance Instructions

  1. Pre-installation Inspection: Check for external damage, intact threads, and presence of sealing gaskets

  2. Bending Requirements: Avoid sharp angle bends; bend radius should not be less than 5 times the hose outer diameter

  3. Tightening Connections: Use a wrench to secure connections with container valve and check valve

  4. Regular Inspection: Monthly visual inspection – check for deformation, corrosion, or leakage

  5. Replacement Cycle: Recommended replacement every 5-8 years or according to system maintenance schedule
