Product Description
Flexible Ceramic-Lined Hose is a composite conveying hose designed
for harsh industrial environments. The inner layer is lined with
high-purity 95% alumina ceramic and the outer layer is a
weather-resistant rubber composite layer. It achieves
"rigid-flexible combination" through an integrated vulcanization
process. It has both the excellent wear resistance of ceramics and
the flexibility of rubber, providing an efficient solution for the
transportation of particles, slurries, and corrosive media.

Production process
Ceramic lining molding:
High-purity alumina powder is isostatically pressed (maximum
pressure 200MPa) and fired in a high-temperature sintering kiln at
1650℃ to form a seamless ceramic tube with a density ≥3.85g/cm³.
Preparation of rubber composite layer:
After the customized formula rubber is mixed, the ceramic layer is
coated by CNC winding/molding process to form a 3-5mm elastic
buffer layer, which fits evenly without gaps.
Overall vulcanization process:
Continuously pressurize in a 180℃ intelligent vulcanization tank
for 4 hours to ensure that the interface bonding strength between
ceramic and rubber meets the standard and achieve "rigidity and
flexibility".
Full process quality inspection:
Hydraulic pressure test (1.5 times the working pressure), wear
resistance test (ASTM G65 standard), airtightness test (helium mass
spectrometry leak detection), and 100% of unqualified products are
eliminated.
Production equipment
Fully automatic isostatic pressing machine: high-precision pressure control to ensure uniform and dense
ceramic lining.
Tunnel-type ceramic sintering kiln: temperature control accuracy ±2℃ to ensure stable performance of
the ceramic layer.
CNC rubber winding production line: accuracy ±0.1mm to achieve uniform coating of the rubber layer.
Intelligent vulcanization tank group: PLC automatic control system, vulcanization process parameters are
precisely controllable.
Three-coordinate measuring machine: dimensional detection accuracy ±0.05mm to ensure product
consistency.

FAQ
Q1: Can you make non-standard sizes?
A: Yes. Provide drawings or working parameters, lead time 15-30
days.
Q2: How to prevent leakage?
A: Use matched clamps and inspect sealing rings regularly.
Q3: How to deal with complex installation space constraints?
A: Provide three-dimensional flexible design services: the minimum
bending radius is reduced to 3 times the pipe diameter, supporting
30°-90° prefabricated elbows
Q4: Will the conveyed material containing sharp metal chips damage
the hose?
A: Using the "gradient ceramic layer" design: Inner layer: high-hardness aluminum oxide (Mohs hardness level 9)/Transition layer: tough zirconium oxide toughened ceramic (fracture
toughness 8MPa·m¹/²)
Q5: What is the minimum order quantity?
A: The minimum order quantity for standard size is 50 meters, and
the minimum order quantity for customized products is adjusted
according to the specifications. Please consult customer service
for details.
Q6: How long is the delivery time for bulk orders?
A: After confirming the technical drawings and payment, the
delivery time for regular orders is 25-35 days, and expedited
production is supported (need to communicate in advance).
Q7: Do you provide samples?
A: Qualified customers can apply for 1 meter long samples for free
(freight to be paid).
