Product Description
In heavy industries such as cement, steel, mining, and chemicals,
the wear and tear of material conveying pipelines is the main
problem leading to a decrease in production efficiency and a surge
in maintenance costs. Rubber-lined pipes, as an efficient and
economical solution, are increasingly becoming the preferred choice
for global industrial enterprises.
Pipeline rubber lining is a composite pipe with a high-performance,
wear-resistant rubber lining firmly bonded to the interior of a
steel pipe. It cleverly combines the mechanical strength of steel
pipe with the superior wear, impact, and corrosion resistance of
high-toughness rubber. Designed specifically for conveying highly
abrasive materials (such as ore, coal powder, cement, and ash), it
significantly reduces pipe wear and extends its service life
several times.


Product Features and Advantages
Extreme Wear Resistance:
Features: Utilizing a specially formulated, highly wear-resistant rubber,
its wear resistance surpasses that of ordinary steel pipes by
dozens of times.
Advantages: Significantly extends pipe replacement cycles, reduces downtime,
and lowers overall maintenance costs.
Excellent impact resistance and cushioning:
Features: The rubber lining has excellent elasticity, effectively absorbing
material impact energy.
Advantages: It prevents large pieces of material from directly impacting the
pipeline, reducing the risk of pipeline rupture. It is particularly
suitable for conveying points with large drop heights.
Excellent anti-clogging and noise reduction:
Features: The rubber surface is smooth, has a low coefficient of
friction, and offers sound-absorbing properties.
Benefits: Ensures smooth material flow and prevents adhesion and
blockage; significantly reduces noise generated during material
conveying, improving the working environment.
Strong corrosion resistance:
Features: The rubber layer effectively resists corrosion from
various chemicals and humid environments.
Benefits: Suitable for conveying corrosive materials or in
high-humidity environments, protecting the steel pipe from
corrosion.
Lightweight and easy installation:
Features: Lighter than solid alloy steel pipes.
Benefits: Easily transported and installed on-site, saving labor
and installation costs.
Applications
This product is widely used in industries with stringent wear
resistance requirements and is an ideal choice for the following
applications:
Mineral processing industry: Tailings conveying, concentrate piping, and mill feed/discharge
pipes.
Coal industry: Coal slurry conveying in coal washeries and coal-water slurry
piping.
Thermal power generation industry: Ash removal systems and fly ash conveying pipelines.
Cement industry: Pneumatic conveying pipelines for raw meal, clinker, and cement
powder.
Steel and iron smelting industry: Dust removal system piping and ore powder conveying.
Chemical industry: Conveying granular raw materials and waste slag.
Ports and terminals: Bulk cargo handling and conveying systems.
Packaging and Shipping
We understand the critical importance of safety during
international transportation. All wear-resistant rubber pipes are
packaged in the following standard packaging:
End Protection: Both ends of the pipe are sealed with flange caps or plastic
sleeves to prevent impact and moisture intrusion.
Rust-Proofing: The outer surface of the steel pipe is treated with anti-rust
paint or epoxy asphalt paint according to customer requirements.
Stable Packaging: Reinforced packaging using wooden crates or iron frames ensures
integrity during long-distance sea and land transport.
Clear Labeling: Each package is clearly labeled with product information,
specifications, dimensions, and destination.
We can provide the most cost-effective and efficient shipping
solutions based on customer needs.


Production Technology and Quality Assurance
Our strength lies not only in our products but also in the
manufacturing expertise behind them.
Advanced Production Technology: Utilizing a high-temperature, high-pressure vulcanization process,
the rubber lining achieves a strong bond with the steel pipe wall,
ensuring it will never fall off during use.
Precision Production Equipment: Equipped with large autoclaves, CNC lathes, and shot blasting
equipment, we ensure precise product dimensions and consistent
quality.
Strict Quality Inspection: From raw material storage to finished product shipment, every
process is subject to rigorous quality inspection. We conduct 100%
testing for key indicators such as bond strength, rubber hardness,
and thickness.

What is a rubber-lined steel pipe?
A rubber-lined steel pipe is a composite pipe where a standard
steel pipe is internally bonded with a layer of wear-resistant
rubber. This combination utilizes the strength of the steel shell
to withstand pressure, while the rubber lining provides exceptional
protection against abrasion, corrosion, and impact, significantly
extending the pipe's service life in harsh industrial applications.
FAQ
Q1: What is the applicable temperature range for rubber-lined
pipes?
A1: Standard models are suitable for temperatures from -20°C to
80°C, meeting the needs of most industrial conveying scenarios. For
customers with high-temperature requirements (such as
high-temperature fly ash conveying in the thermal power industry),
custom high-temperature models can be customized, with an
applicable temperature of up to 120°C.
Q2: What are the pipe connection methods? Are they compatible with
existing pipes?
A2: Flange and quick-connect connections are supported. Flange
standards comply with international standards such as GB, ANSI, and
DIN, making them directly compatible with existing steel pipes,
valves, and other equipment, eliminating the need to modify
existing conveying systems.
Q3: How can I determine if a pipe needs to be replaced? What are
the warning signs before its service life expires?
A3: It is recommended to regularly (every 3-6 months) inspect the
appearance of the pipeline. If any of the following situations
occur, they should be replaced promptly: ① obvious corrosion or
bulging on the outer wall of the pipeline; ② Frequent water leakage
at the interface, which cannot be resolved even after repair; ③ The
conveying pressure has significantly decreased, or the amount of
medium conveyed has decreased (possibly due to the wear of the
lining rubber causing the inner wall to become rough and the
resistance to increase).
Q4: Does this product come with a warranty? How long is the
warranty period?
A4: The rubber lining of steel pipes comes with a one-year
warranty. During the warranty period, if the pipe becomes
inoperable due to quality issues (such as separation of the rubber
from the steel pipe or cracking of the lining), we will repair or
replace it free of charge. We also provide lifetime technical
support. If you encounter any problems during use, please contact
our technical team at any time for solutions.
