RRL Reinforced Rubber Lined Hose Pipes: Unmatched Durability for Critical Applications

Engineered for Extreme Performance & Reliability

In demanding environments where every moment counts, the integrity of your equipment is paramount. Our RRL (Reinforced Rubber Lined) Hose Pipes are meticulously engineered to deliver superior performance, exceptional durability, and unwavering reliability in the most challenging conditions. Designed for firefighting, industrial, agricultural, and heavy-duty water transfer applications, these hoses are the ultimate solution for critical fluid conveyance.

What is RRL?

RRL stands for Reinforced Rubber Lined. This construction refers to a hose featuring an inner liner made of high-grade synthetic rubber, reinforced by multiple plies of high-tenacity synthetic yarn, all encased within a robust outer jacket. This multi-layered design provides unparalleled strength, longevity, and resistance to environmental factors.

Key Features & Benefits:

• Exceptional Durability:
  • High-Grade Synthetic Rubber Liner: Provides a smooth, seamless inner surface for optimal flow and superior resistance to abrasion, chemicals, and aging.
  • Multi-Ply Synthetic Yarn Reinforcement: Offers incredible burst strength and pressure resistance, ensuring reliability even under high operational demands.
  • Robust Synthetic Outer Jacket: Woven from high-tenacity polyester fibers, the outer jacket delivers outstanding resistance to cuts, snags, abrasion, UV exposure, and general wear and tear.
• Superior Performance:
  • High Working & Burst Pressure: Engineered to safely handle significant pressure, making them ideal for high-volume pumping and firefighting.
  • Optimized Flow Dynamics: The smooth rubber lining minimizes friction loss, ensuring maximum flow rate and efficient fluid transfer.
  • Wide Temperature Range: Maintains flexibility and performance across a broad spectrum of temperatures, from freezing cold to intense heat.
• Low Maintenance & Longevity:
  • Rot & Mildew Proof: The synthetic materials are inherently resistant to rot, mildew, and fungal growth, reducing maintenance needs and extending service life.
  • UV & Ozone Resistant: Designed to withstand prolonged exposure to sunlight and environmental elements without degradation.
  • Chemical & Oil Resistance: The specialized rubber lining offers protection against a variety of chemicals, oils, and hydrocarbons.
• Ease of Handling:
  • Flexible & Lightweight: Despite their heavy-duty construction, RRL hoses offer good flexibility, making them easier to deploy, retrieve, and store compared to traditional rubber hoses.
  • Compact Storage: Can be rolled flat for efficient storage, saving valuable space.

Construction Details:

1. Inner Liner: Made from a seamless, high-quality synthetic rubber compound (e.g., EPDM, Nitrile blend), ensuring a smooth bore and excellent resistance to water, many chemicals, and aging.
2. Reinforcement: Consists of multiple plies of high-strength, circularly woven synthetic yarn (typically polyester). This reinforcement is embedded between the inner liner and the outer jacket, providing the hose with its crucial pressure-bearing capability.
3. Outer Jacket: Constructed from high-tenacity synthetic polyester staple fiber, circularly woven for maximum strength. This jacket is treated to enhance resistance against abrasion, cuts, snags, UV radiation, and environmental degradation. The weave density contributes significantly to the hose's external durability.

Typical Applications:

• Firefighting: Municipal fire departments, industrial fire safety, marine firefighting.
• Industrial: Water transfer, dewatering, process lines, chemical transfer (check compatibility).
• Agricultural: Irrigation, water supply for livestock, slurry transfer.
• Construction: Dewatering of construction sites, transfer of water and mild slurries.
• Mining: Water management, dewatering operations.
• Marine & Offshore: Shipboard applications, dockside water transfer.
• Municipal: Emergency water supply, hydrant connections.
