Material Handling Hose for Bulk Solids Transfer
These hoses handle abrasive dry bulk—powders, pellets, sand, gravel, cement, and fly ash—under suction and discharge, including pneumatic conveying and vacuum truck service. They balance wear resistance, flexibility, and static control for continuous use in mining, construction, concrete placement, blasting, and plant maintenance.

Applications and Conveyed Media
- Dry bulk powders and pellets: Smooth-bore or low-drag liners support pneumatic systems. A steel helix enables full vacuum, with conductive or static-dissipative options for dusty zones.
- Sandblasting and shot peening: Thick, abrasion-resistant tubes deliver consistent service life with garnet, steel shot, or silica alternatives. Tight bend radius suits portable and cabinet blasting.
- Concrete placement and grout: Multi-ply reinforcement resists kinking and pump pulsation. Stable IDs help maintain flow and secure coupling retention.
- Vacuum truck and industrial cleanup: Embedded helix provides crush resistance and near-full vacuum capability for dry solids and slurries. Durable covers protect against abrasion.
Key Construction and Features
- Tube compounds and anti-static options: NR/SBR, BR, or wear-optimized blends targeting ≤50–70 mm³ abrasion (DIN-indicative). Static-dissipative and fully conductive constructions available. See the Anti-Static Industrial Rubber Hose for Explosive Areas for hazardous dust zones.
- Electrical continuity and safety: Conductive tube-and-cover designs (typical R < 10^6 Ω), grounding wires, and marked continuity paths support safe installation and on-site checks.
- Reinforcement and safety factor: High‑tensile textile plies with optional steel helix provide vacuum stability and crush resistance. Concrete variants add plies for higher pulsation. Typical safety factor is 3:1; higher on request.
- Cover durability: Thick, cut- and ozone-resistant covers withstand dragging and curb rub. Wrapped or smooth finishes suit handling and cleaning needs.
- Temperature, pressure, and vacuum: Standard operation from -40°C to +80°C; selected blends up to +120°C. Typical working pressures are 10–20 bar for bulk transfer and higher for concrete placement. Vacuum ratings to -0.9 bar vary by ID and construction.
Specifications and Size Range
- Sizes and bend radius: Common IDs from 1–12 in (25–300 mm); larger bores on request. Wall design and helix geometry help maintain a low bend radius without collapse under vacuum.
- Working pressure and pulsation: Bulk transfer hose handles steady flow and intermittent surges. Concrete pump variants tolerate elevated pulsation.
- Abrasion performance: Wear-optimized liners targeting ≤50–70 mm³ (DIN-based) extend service intervals with sharp or angular media.
Product Range
- Bulk material suction and discharge hose: Textile-reinforced with steel helix; anti-static options for plant or field use.
- Sandblast hose (high abrasion): Standard and heavy-wall profiles for portable and fixed systems.
- Concrete placement hose: Multi-ply, high-pulsation designs with precise ID control to support secure coupling fit.
- Grout delivery hose: Flexible options for fine aggregates and admixtures; non-marking covers available.
- Lightweight PU reinforced corrugated hose: PU construction for dust and light powder extraction lines.
- Food-grade powder transfer hose: Smooth-bore designs for sugar, flour, starch, and dairy powders; wire-reinforced suction options.
Quality, Testing, and Documentation
- Traceable materials and controlled processes with in‑line inspection from compounding to cure.
- Recorded pressure, vacuum, and abrasion testing; third‑party validation available to specified standards.
- Assemblies with camlocks, flanges, or nozzles can be factory-crimped and verified hydrostatically and electrically, with serialized traceability. Conformance packs and inspection reports are provided to project needs.
Delivery and Support
- Short lead times with milestone updates, export-ready packaging, and global logistics. After‑sales support responds promptly from startup onward.
Selection Guide for Bulk Solids Hose
- Match media and abrasion level: Consider hardness, angularity, and particle size; select liner and wall thickness accordingly.
- Suction vs. discharge and routing: Suction lines need helix reinforcement and higher wall stiffness. Verify bend radius to prevent kinking.
- Electrical continuity and site safety: Specify conductive or static‑dissipative designs. Bond and ground couplings, and confirm continuity at commissioning.
- Couplings and assembly fit: Match coupling type and ferrule to hose ID and wall. Factory‑crimped assemblies reduce leak paths and installation time.
FAQ
- Q: What is a material handling hose?
A: It is a flexible hose for abrasive dry bulk under suction or pressure, designed with wear‑resistant liners and reinforcements for vacuum control and durability.
- Q: Can it be used for pneumatic conveying?
A: Yes. Choose smooth‑bore, static‑controlled constructions with suitable vacuum rating and bend radius.
- Q: How do I ground a conductive hose?
A: Use a conductive tube-and-cover with a grounding wire. Bond couplings to plant ground and verify continuity with a multimeter.
- Q: What sizes are available?
A: Standard IDs are 1–12 in, with larger sizes on request. Cut lengths and tested assemblies can be supplied for your layout.
