【Product Overview】

Composite hose is a special flexible pipeline designed for conveying corrosive fluids and flammable/explosive media, formed by multi-layer composite technology, combining the strength of metal pipes with the flexibility of rubber/plastic pipes. Its core advantages include zero leakage, corrosion resistance and anti-static properties, replacing traditional metal and rubber hoses to solve common issues like corrosion, leakage and difficult installation in chemical media transportation. Different inner and outer materials can be selected according to conveyed media, adapting to acids, alkalis, solvents, oils, gases and other media, widely used in petrochemical, port loading/unloading, pharmaceutical manufacturing and sewage treatment industries.

【Structure & Core Materials】

The composite hose adopts a multi-layer composite structure with clear functions for each layer to ensure safe conveying:

1. Inner Layer: Made of chemical-resistant materials (PTFE, polyolefin, special rubber) according to media characteristics, resisting acids, alkalis and solvents, preventing penetration, with smooth inner wall reducing media residue and contamination.
2. Reinforcement Layer: Braided or wound with high-strength stainless steel wire, galvanized steel wire or synthetic fiber, enhancing tensile and burst resistance for both positive and negative pressure conveying conditions.
3. Outer Layer: Weather-resistant and aging-resistant materials (PVC, TPU, neoprene), anti-UV, wear-resistant and corrosion-resistant, protecting against outdoor and harsh environmental erosion.
4. Connections: Standard flanges, quick couplings, threaded connections and customized options, adapting to different equipment interfaces for easy installation and reliable sealing.

【Core Performance Advantages】

1. Excellent Corrosion Resistance: The inner layer adapts to strong acids, alkalis and organic solvents, with better chemical resistance than ordinary rubber and metal pipes, no corrosion or leakage during long-term conveying.
2. High Flexibility & Easy Installation: The hose can be bent arbitrarily, adapting to complex pipeline layouts without special tools, reducing installation costs and difficulty.
3. Leak-proof & Zero Leakage: Multi-layer composite structure and special connection design eliminate media leakage, especially suitable for flammable, explosive and toxic media with high safety factor.
4. High/Low Temperature & Weather Resistance: Stable operation from -40℃ to +120℃ (extended to higher temperatures for special models), anti-aging and anti-UV, no cracking or hardening after long-term outdoor use.
5. Anti-static Safety: Some models have built-in conductive layers to discharge static electricity, avoiding sparks during flammable media conveying, meeting chemical safety standards.
6. Complete Specifications & Customization: Caliber range DN15~DN200, customizable length, connection type and material for personalized design to match various equipment and scenarios.

【Application Scenarios】

• Petrochemical Industry: Conveying crude oil, refined oil, acid-base solutions, organic solvents and chemical gases for reactors, storage tanks and loading/unloading equipment.
• Port Terminal Loading/Unloading: Media loading/unloading for oil tankers and chemical ships, replacing traditional hard pipes to reduce leakage risks.
• Pharmaceutical & Food Industry: Conveying food-grade solvents and pharmaceutical intermediates with food-grade materials, non-toxic and odorless, meeting hygiene standards.
• Environmental Protection & Sewage Treatment: Conveying sewage, corrosive waste liquids and acid-base neutralization solutions with long service life.
• Other Industrial Scenarios: Conveying paints and solvents in mechanical processing and coating industries, and flexible conveying of various industrial fluids.
