Construction Hose

Construction hoses and heavy duty industrial hoses are specialized fluid/material transfer components designed for high-intensity, harsh-environment applications—unlike ordinary industrial hoses, they must withstand extreme pressure, heavy wear, impact, and exposure to construction debris, chemicals, or extreme temperatures.

• Construction hose: Focused on supporting construction site operations, it is mainly used for transferring concrete, sand, gravel, mud, water, and other construction materials, as well as connecting hydraulic systems of construction machinery (such as excavators, loaders, and concrete pumps).
• Heavy duty industrial hose: Wider in application, covering mining, metallurgy, port logistics, and heavy machinery industries, it is suitable for high-pressure oil transmission, bulk material suction/discharge (such as coal, ore), and high-temperature fluid transfer, requiring ultra-high durability and pressure resistance.

At Orientflex, we integrate 15+ years of industrial hose R&D experience into every construction and heavy-duty industrial hose, ensuring that each product can cope with the “high load, high frequency, high risk” challenges of worksites.

As a professional of heavy-duty fluid transfer solutions, Orientflex’s construction and heavy duty industrial hoses are built with “durability, safety, and efficiency” as the core, and have 5 key advantages that stand out in the industry:

1. Anti-Wear & Anti-Tear Heavy-Duty Material

• Inner tube: For concrete / sand transfer hoses, we use high-hardness natural rubber or polyurethane (PU) with ultra-low friction coefficient, which reduces material adhesion and wear—compared with ordinary rubber hoses, the wear resistance is increased by 30%.
• Reinforcement layer: Uses high-tensile polyester or spiral steel wire, which can withstand working pressures up to 30MPa (4350 psi) and burst pressures up to 120MPa, avoiding hose rupture caused by high-pressure material impact.
• Outer cover: Adopts weather-resistant, oil-resistant, and anti-aging synthetic rubber (EPDM or SBR), which can resist UV radiation, -40℃ low temperature to 120℃ high temperature, and chemical corrosion (such as alkaline concrete admixtures, mineral oil), ensuring long-term use in outdoor or harsh industrial environments.

2. Complex Worksite Scenarios Adapted Structure

• Flexible yet kink-resistant: The reinforcement layer is woven in a “cross spiral” way, which maintains flexibility (bending radius ≥ 5 times the hose diameter) while preventing kinking during equipment turning or dragging, avoiding material blockage.
• Anti-collision & anti-puncture: For hoses used in mining or road construction, an additional 1.5mm thick wear-resistant rubber layer is added to the outer cover, which can resist puncture by stones, steel bars, or sharp construction waste.
• Quick-connect compatibility: The hose ends are pre-processed with standard thread (BSP, NPT) or flange interfaces, which can be quickly connected to concrete pumps, excavator hydraulic ports, or material tanks, reducing installation time by 50% compared with ordinary hoses.

3. High-Pressure & High-Flow Performance

• High-pressure resistance: Orientflex heavy duty industrial hoses for hydraulic systems meet ISO 1436-1 standards, with a working pressure range of 10-30MPa, which can match the high-pressure hydraulic needs of large construction machinery (such as 200-ton excavators).
• Large flow design: The inner diameter of construction hoses (such as concrete transfer hoses) is available in 50-200mm specifications, and the smooth inner wall design reduces fluid resistance—for example, the 100mm diameter concrete hose can achieve a flow rate of 80m³/h, meeting the needs of high-rise building concrete pouring.
• Vacuum resistance: For sand, gravel, and ore suction hoses, the reinforcement layer is designed with “negative pressure resistance” to avoid hose collapse under -0.9bar vacuum, ensuring continuous suction of bulk materials.

4. Global Industrial Standards Compliant

• Construction hose compliance: Meets EN 853 (Europe) standards for hydraulic rubber hoses, and concrete transfer hoses comply with ASTM D1774 standards, ensuring no harmful substances are released and no pollution to construction materials.
• Heavy duty industrial hose compliance: Mining hoses meet ISO 3862 standards for oil-resistant hoses, and high-temperature hoses meet DIN 20024 standards, which are suitable for metallurgical industry high-temperature oil transmission (up to 120℃).
• Safety testing: Every hose undergoes 3 strict tests before leaving the factory:
  1. Hydrostatic pressure test: Maintain 1.5 times the working pressure for 5 minutes, no leakage or deformation.
  2. Air tightness test: Test under 0.8MPa air pressure, no air leakage.
  3. Wear test: Simulate 10,000 times of dragging on concrete ground, the outer cover wear is less than 0.5mm.

5. All Customizable for Your Unique Worksite Needs

• Specification customization: Inner diameter (25-300mm), length (1-100m), and wall thickness can be customized according to the size of construction machinery or material transmission distance.
• Material customization: For acid-base environments (such as chemical plant construction), we provide EPDM inner tube hoses with strong acid resistance; for low-temperature regions (such as northern winter construction), we use low-temperature resistant rubber (-40℃ non-brittle) to avoid hose cracking.
• Accessory matching: Provide customized fittings (such as quick connectors, check valves, and pressure gauges) to form a complete “hose + accessory” system, avoiding compatibility problems caused by mixed use of different brands.
