Introduction to Corrosion-Resistant Liners, Rubber Liners, and Equipment Liners

Corrosion-resistant lining is a type of lining where the outer layer is a steel pipe structure, and the inner lining is made of wear-resistant, corrosion-resistant, and high-temperature-resistant rubber. The physical and chemical properties of the rubber reduce the impact of the transported material on the outer structure, such as impact and corrosion. Due to the buffering effect of the rubber, the service life of the pipeline is greatly extended, and the user's cost is reduced.

Product Characteristics of Corrosion-Resistant Liners, Rubber Liners, and Equipment Liners

It mainly utilizes the unique properties of rubber: high elasticity, high airtightness, impact resistance, wear resistance, weather resistance, radiation resistance, chemical resistance, and vibration absorption. Rubber also has good bonding strength with metals, making it suitable for lining chemical equipment. Therefore, it is widely used in pipelines, pipe bodies, and containers for handling acids, alkalis, and salts, as well as in reactors, pumps, valves, and mixers, solving corrosion problems in pipeline equipment.

Application Range of Corrosion-Resistant Liners, Rubber Liners, and Equipment Liners

This lining product is divided into three categories: vulcanization in vulcanization tanks, room temperature vulcanization, and pre-vulcanization. It is available in three series: hard rubber, soft-hard composite rubber, and five types of rubber (natural rubber, butyl rubber, chloroprene rubber, chlorinated butyl rubber), totaling more than 30 varieties to meet the corrosion prevention needs of various equipment. It is mainly used in power desulfurization, metallurgy, petroleum, chemical, food, medical, pharmaceutical, mining, building materials, textile, papermaking, and urban construction industries. It is an ideal environmentally friendly product that can withstand high and low temperatures.

Working Principle of Rubber-Lined Pipelines

Using the "soft overcomes the hard" principle of rubber, it solves the problem of pipeline lining, mainly focusing on wear resistance. The wear resistance, corrosion resistance, and high-temperature resistance of rubber provide good protection for the pipeline.

Advantages of Rubber Linings

1. Excellent Structure: The reinforced steel pipe and rubber layer of the pipe are combined into one using a high-performance adhesive, overcoming the shortcomings of steel pipes being pressure-resistant but not wear-resistant, and rubber being wear-resistant but not pressure-resistant. It combines the advantages of steel pipes and wear-resistant rubber, with excellent comprehensive cost performance.

2. Excellent Corrosion Resistance: Except for concentrated sulfuric acid, chromic acid, and other strong oxidizing acids and aromatic alkanes, it has good corrosion resistance to almost all media.

3. Excellent Wear Resistance: The elastic soft lining not only absorbs mechanical vibrations but also absorbs the corrosion caused by the stirring of materials with strong frictional properties.

4. High Strength and Impact Resistance: The density of the rubber elastomer is low, the weight is light, it has good vibration absorption performance and excellent resistance to mechanical impact. It has high strength, good rigidity, no creep, strong impact resistance, shock resistance, and water hammer resistance, making it easy to transport, install, and maintain.

5. Strong Adaptability: Before vulcanization, the rubber lining can be freely deformed into any shape, so it can be lined on complex equipment. The bonding strength between the rubber and the metal substrate is high, and the rubber is bonded together. After vulcanization, it becomes one body.

6. Wide Temperature Adaptability: Rubber-lined pipelines can be used for a long time in the range of -50°C to +150°C, and the rubber lining will not separate from the steel frame due to temperature changes.

7. Excellent Anti-aging Performance and Long Service Life: Under normal pressure, temperature, and medium use, the general service life is more than 15 years (theoretical value). After 6-8 years of use, the pipeline is rotated 90° once, and the service life will be longer; rubber-lined pipelines can be relined repeatedly, reducing costs.
