Technical Specifications and Construction

The structural integrity and performance of a hose are defined by its technical specifications and meticulous construction. The AIR-WATER hose 20 bar/300psi is engineered with a multi-layered design to ensure optimal performance and safety under its rated conditions.

Hose Construction:

• Inner Tube: Typically crafted from high-quality Synthetic Rubber, such as SBR (Styrene Butadiene Rubber) or a blend of SBR/NR (Natural Rubber). This choice provides excellent resistance to air, water, and mild chemicals, ensuring a smooth flow path and preventing material degradation from the conveyed media.
• Reinforcement: Comprised of high-strength textile braids or plies. This critical layer provides the structural integrity required to withstand the specified working pressure of 20 bar (300 psi) and protect against collapse under vacuum. The type and density of textile reinforcement are carefully calculated to balance pressure resistance with flexibility.
• Outer Cover: Made from a durable synthetic rubber compound, often EPDM (Ethylene Propylene Diene Monomer) or SBR/NR blend, engineered for superior resistance to external aggressors. This includes abrasion, ozone, weathering, UV radiation, and in some cases, oil mist or chemical splashes, thereby extending the hose's service life in demanding industrial environments.

Manufacturing Process of AIR-WATER hose 20 bar/300psi

The production of a high-performance industrial hose like the AIR-WATER hose 20 bar/300psi involves a series of meticulously controlled stages, integrating advanced material science with precision engineering. The process ensures durability, pressure resistance, and a consistent service life.

Schematic Process Flow:

1. Material Preparation & Compounding: Raw rubber polymers (e.g., SBR, NR, EPDM) are mixed with specific additives, fillers, vulcanizing agents, and accelerators. This compounding process is crucial for achieving desired properties like flexibility, chemical resistance, and high-temperature performance.
2. Inner Tube Extrusion: The compounded rubber is fed into an extruder, where it is heated and forced through a die to form the seamless inner tube. Precise control over temperature and die geometry ensures uniform wall thickness and a smooth inner surface, critical for flow efficiency and longevity.
3. Reinforcement Application (Braiding/Spiraling): After the inner tube cools, it moves to the braiding or spiraling machinery. High-strength textile cords (e.g., polyester, nylon) are applied in one or more layers, often in a crisscross pattern, to provide the necessary pressure bearing capability. The tension and angle of the reinforcement are carefully controlled to achieve optimal burst pressure and flexibility.
4. Outer Cover Extrusion: Another layer of compounded synthetic rubber (the cover) is extruded over the reinforced core. This outer layer is designed to protect the hose from external abrasion, ozone, UV radiation, and other environmental factors.
5. Vulcanization (Curing): The assembled hose is then subjected to a vulcanization process, typically in an autoclave with steam or through continuous vulcanization lines. This heat treatment chemically cross-links the rubber molecules, giving the hose its final elastic properties, strength, and permanent shape.
6. Testing & Quality Control: Post-vulcanization, each batch undergoes rigorous testing. This includes hydrostatic pressure tests to verify working and burst pressures (e.g., according to ISO 1307 and ISO 2398 standards), bend radius tests, adhesion tests between layers, and dimensional checks. Our products are also subjected to tests for ozone resistance and abrasion resistance, ensuring compliance with international quality benchmarks.
7. Finishing & Packaging: Once all tests are passed, the hose is cut to specified lengths, branded, and prepared for shipping.

This controlled manufacturing environment ensures that each hose meets the specified 20 bar/300 psi working pressure, offering an excellent service life of typically 5-10 years under normal operating conditions, depending on application severity and maintenance practices.

Key Technical Advantages

The engineering excellence behind our AIR-WATER hose 20 bar/300psi translates into several distinct advantages for industrial applications:

• Superior Pressure Management: Designed for a working pressure of 20 bar (300 psi) with a robust 3:1 safety factor, ensuring reliable operation in high-pressure air and water transfer systems, minimizing the risk of rupture.
• Enhanced Durability and Longevity: The synthetic rubber compounds used for the inner tube and outer cover, combined with high-strength textile reinforcement, provide exceptional resistance to abrasion, kinking, crushing, and environmental degradation (ozone, UV), leading to a longer operational lifespan.
• Wide Temperature Tolerance: Capable of performing reliably across a broad temperature range from -25°C to +80°C, making it suitable for diverse climates and demanding industrial processes without compromising flexibility or integrity.
• Corrosion Resistance: The specialized rubber compounds offer inherent resistance to water, air, and many common industrial chemicals, preventing internal and external corrosion that can degrade metal piping or lesser quality hoses. This significantly reduces maintenance and replacement frequency.
• Optimal Flow Characteristics: The smooth inner bore minimizes turbulence and friction loss, contributing to energy saving in pumping and compression systems by maintaining efficient fluid transfer and reducing the workload on equipment.
