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.

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.
