Heavy Duty Composite Hose

The JIDONGDA Heavy Duty Composite Hose is a reinforced, flexible hose specifically designed for demanding industrial fluid transfer and material handling operations. Unlike standard composite hoses, this model features additional multi-layer reinforcement, enabling it to withstand high flow rates, frequent usage cycles, and the rigors of continuous, long-term operation. Offering excellent flexibility, the hose withstands repeated bending and dragging, as well as rapid installation and dismantling. It is an essential component of fluid transport systems in heavy industry, suitable for applications such as high-volume fluid transfer, intensive port loading and unloading operations, and use in stationary industrial transport systems.

Product Construction

The product features a four-layer composite modular structure, with each layer performing a specific reinforcing function to ensure performance under heavy-duty and challenging conditions:

1. Multi-layer chemically resistant inner layer

A composite polymer film structure that significantly reduces the risk of working fluid permeation. The material is compatible with various industrial media (including oils, chemical fluids, and slurries), preventing corrosion of the inner walls and contamination of the pumped product.

2. Reinforced spiral framework

A support layer consisting of a heavy-gauge stainless steel spiral; this significantly enhances resistance to internal pressure and external vacuum compression, effectively preventing structural deformation or collapse during vacuum pumping or dredging operations.

3. High-strength textile layer

A braiding layer made of high-strength industrial fiber that increases the hose's overall tensile strength and impact resistance, while also providing protection against mechanical damage during lifting, dragging, or impacts.

4. Protective outer coating

An abrasion-resistant PVC or rubber outer layer designed to withstand weather conditions, seawater corrosion, and mechanical wear, making it suitable for long-term outdoor and marine use.

Frequently Asked Questions

Q1: Can the JIDONGDA reinforced Heavy Duty Composite Hose handle negative-pressure suction conditions for mine slurry?

A1: Yes. The product features a reinforced stainless steel helix that provides excellent negative-pressure resistance; this allows for stable operation under full vacuum conditions and prevents the hose from collapsing. It is suitable for suctioning slurry, sludge, and industrial wastewater; reinforced versions are available for applications requiring large diameters and high vacuum levels.

Q2: Can this Heavy Duty Composite Hose be used to transport highly aggressive media, such as strong acids and alkalis? What specifications are required?

A2: Yes, the product is suitable for transporting aggressive media. For handling highly aggressive substances (such as acids, alkalis, and organic solvents), we offer a special corrosion-resistant PTFE inner liner combined with a 316L stainless steel helix and an explosion-proof, anti-static design. This configuration prevents media permeation and corrosion while eliminating static electricity risks, making it an ideal solution for transporting aggressive fluids at chemical plants and bulk liquid terminals.

Q3: Which international connection standards does this product support to ensure integration with overseas equipment?

A3: The product is compatible with the three major international flange standards—ANSI, DIN, and JIS—and can also be equipped with universal quick-connect systems. This ensures seamless integration with loading arms, tanker trucks, and ship piping systems worldwide without the need for modifications, making it suitable for a wide range of international engineering projects.
