3 Inch Corrugated Suction Hose

Built with a rugged corrugated exterior and a smooth-flow interior, this 3 inch suction hose ensures minimal friction loss while maximizing flow efficiency. Whether you’re draining muddy construction pits, irrigating vast farmland, or handling heavy-duty industrial pumping, this hose delivers—day in, day out.

Basic Characteristics of 3 Inch Corrugated Suction Hose

Corrugated Suction Hose is a flexible pipe made from polyvinyl chloride (PVC) and reinforced with polyester fiber layers, designed for suction applications involving water, air, and non-corrosive granular materials (e.g., sand). The outer wall features spiral PVC reinforcement ribs (plastic ribs) to enhance pressure resistance while maintaining flexibility. Common colors include orange (industrial use), yellow, and black (UV-resistant). Standard lengths are 20/30 meters, with diameters customizable from 25-150mm.

Advantages over rubber hoses:

• 35%-40% lighter weight, allowing for easy handling and deployment

• Smooth inner wall (friction coefficient: 0.008) reduces water flow resistance

• Approximately 25% lower cost

Limitations:

• Becomes stiff in low temperatures (< -5°C); recommended to coil for winter storage

• For prolonged sun exposure, choose UV-resistant models

Typical applications: Agricultural irrigation, construction site dewatering, municipal emergency water pumping, etc.

Key Performance Parameters

• Pressure Resistance: Working pressure 4-10bar, burst pressure up to 2x working pressure

• Flow Efficiency: 100mm diameter achieves ~80m³/h flow rate at 6bar

• Abrasion Resistance: Reinforced ribs improve wear resistance by 3x compared to standard PVC hoses

• Temperature Range: -5°C to +60°C

Selection & Installation Guidelines (Bullet Points)

1. Diameter Matching:

   25-50mm: Suitable for low-flow pumping (<30m³/h)

   65-100mm: Ideal for medium drainage (50-100m³/h)

   150mm: Used for high-flow emergency pumping

2. Pressure Compatibility: Select a working pressure ≥1.5x the pump’s max output

3. Installation Best Practices:

   Lay with ribs facing outward for better abrasion resistance

   Secure joints with stainless steel clamps (torque ≥2.5N·m)

   Support suspended sections every 1.5 meters

4. Terrain Adaptability:

   Flat surfaces: Direct laying

   Rocky terrain: Use protective sleeves

This image features a 3 - Inch Corrugated Suction Hose. The hose is green and corrugated, providing flexibility for various suction tasks. It is equipped with a metallic coupling, which is securely fastened with metal clamps. This setup ensures a tight seal and reliable connection, making the hose suitable for applications that require efficient suction, such as in industrial fluid transfer or agricultural irrigation.

Maintenance & Troubleshooting

Routine Maintenance:

• Flush inner walls after use to prevent sediment buildup

• Coil storage diameter ≥15x hose diameter

Common Issues & Solutions:

• Deformation: Soak in 60°C hot water to restore shape

• Leaky Fittings: Replace O-rings (ensure size matches hose diameter)

• Cracked Ribs: Temporarily wrap with PVC repair tape

Typical Use Cases

• Agriculture: 50mm transparent hose with centrifugal pumps for visible water flow

• Construction Sites: 80mm blue hose for dewatering excavations 

• Pond Management: 100mm black hose for algae-filled water (UV-resistant)

• Municipal Drainage: 150mm reinforced hose for short-term silt pumping (requires filters)
