Rubber Hose Weather And UV Resistant Lightweight And Easy To
Install
Description
The slurry suction hose is an essential solution for industrial
waste and sludge handling, designed to transport abrasive, viscous,
or chemically active slurries from treatment tanks, basins, or
processing areas to treatment plants, disposal sites, or recycling
systems. These hoses must endure abrasive particles, corrosive
chemicals, high solids content, and continuous suction while
maintaining structural integrity, flexibility, and long-term
operational reliability.
Industrial waste streams, such as paper mill sludge, chemical plant
residues, or mining wastewater, often present significant
challenges due to high abrasiveness, corrosiveness, and
unpredictable flow characteristics. Standard hoses typically fail
prematurely from liner wear, vacuum collapse, or chemical
degradation, resulting in downtime and increased operational costs.
Hongruntong Marine slurry suction hoses are engineered to address
these issues, offering high wear resistance, chemical
compatibility, vacuum stability, and flexible handling suitable for
industrial applications.
Case Study: Chemical Processing Plant Sludge Transfer
A chemical plant needed to transport waste slurries containing fine
solids and mild acidic compounds from processing basins to
treatment tanks over 200 meters. Previous hoses failed after a few
hundred hours due to liner abrasion and chemical degradation.
Hongruntong supplied 300 mm ID slurry suction hoses with a thick
chemical- and abrasion-resistant liner, dual steel wire helix
reinforcement, synthetic textile plies, and external protective
covers. Over 1,000 operational hours, the hoses maintained
integrity, resisted chemical attack, and allowed continuous sludge
transfer without leaks or vacuum failure. The client reported a 40%
reduction in maintenance interventions and significant operational
cost savings.

Key Features
Chemical and Abrasion-Resistant Inner Liner
The inner liner is formulated with specialized rubber compounds
combining natural rubber, SBR, and chemical-resistant additives to
withstand abrasive and corrosive slurries. Its thick construction
ensures uniform wear and long service life, even when transporting
fibrous, solid-laden, or chemically aggressive industrial waste.
This feature reduces maintenance frequency and ensures consistent
operational efficiency.
Robust Multi Layer Reinforcement
The hose includes a dual steel wire helix combined with synthetic
textile plies for structural stability. The steel helix provides
resistance to vacuum collapse, while the textile plies distribute
tensile and bending loads. This design ensures hoses can handle
continuous suction, frequent flexing, and mechanical stress typical
in industrial environments without structural failure.
Durable External Cover
The outer cover protects against abrasion, chemical exposure,
mechanical impact, UV, and ozone degradation. Industrial settings
often involve contact with machinery, floors, and corrosive
liquids. Optional reinforced overlays or scuff strips enhance
protection in high-wear areas, ensuring long-term reliability and
operational safety.
Optimized Flexibility and Vacuum Performance
Hongruntong hoses balance flexibility and structural rigidity,
allowing them to navigate complex plant layouts while maintaining
vacuum stability under high suction. The optimized bend radius and
wall thickness transitions prevent kinking, reduce stress
concentrations, and maintain consistent flow rates, essential for
continuous sludge transfer operations.
Applications
Chemical and Process Industry Waste
Slurry suction hoses transfer waste streams containing chemical
residues, fine solids, or abrasive particles from processing tanks
to treatment facilities. Hoses must resist chemical attack,
abrasion, and vacuum collapse while maintaining flexible routing in
plant layouts.
Pulp, Paper, and Fibrous Sludge Handling
Industrial hoses transport fibrous slurries from holding tanks to
dewatering units. Hoses require high abrasion resistance and
flexibility to prevent clogging, ensure continuous flow, and
withstand repeated flexing during plant operation.
Mining and Mineral Waste Slurries
In industrial settings handling tailings or mineral waste, hoses
transport abrasive and dense slurries to storage, treatment, or
disposal sites. They must withstand heavy solids, maintain vacuum
integrity, and resist wear, providing reliable, continuous service.

FAQ
1. What is the expected lifespan of industrial waste hoses?
Lifespan depends on abrasiveness, chemical composition, suction
pressure, and operation schedule. Typically, Hongruntong hoses last
1,000–2,000 operational hours in industrial sludge handling before
significant liner wear occurs.
2. Can the hose handle negative pressure without collapsing?
Yes. Dual steel wire helix reinforcement and synthetic plies ensure
vacuum stability even under high suction conditions. Hoses are
tested with safety margins above design pressure.
3. Are hoses suitable for chemically aggressive slurries?
Yes. Hoses can be supplied with chemical-resistant inner liners
(EPDM, neoprene, or custom compounds) based on slurry composition,
ensuring compatibility and longevity.
4. What end fittings are available for industrial applications?
Flanged ends (ANSI, DIN, JIS), quick-connect couplings, cam-lock
systems, and swivel joints are available. Fittings are designed for
smooth flow and minimal stress concentration.
5. What maintenance practices are recommended?
Regularly inspect liner thickness, flush hoses after use, avoid
sharp bends, secure hoses to prevent external abrasion, monitor for
leaks or distortion, and maintain spare hose segments for quick
replacement.
