Rockwool Pipe
Rock wool pipes are made of natural basalt as the main raw material. After high-temperature melting, they are made into artificial inorganic fibers by high-speed centrifugal equipment, and special adhesives and dust-proof oils are added. They are then heated and cured to make rock wool insulation pipes of various specifications and different requirements.

Rockwool Pipe Insulation
Rockwool pipe is a high-performance insulation material widely used in industrial and construction applications. As part of our rock wool insulation materials, rockwool pipe offers excellent thermal insulation, fire resistance, and acoustic properties, making it an essential solution for a wide range of pipeline systems.

Types of Rockwool Pipe
1. Ordinary rockwool pipe
This is the most common type of rockwool pipe, usually made of a mixture of rockwool fiber and polyester fiber. It has good thermal insulation and noise reduction effects, and is suitable for the insulation and sound insulation of various pipes.
2. Aluminum foil rockwool pipe
On the basis of ordinary rockwool pipe, aluminum foil rockwool pipe adds a layer of aluminum foil protective layer. This layer of aluminum foil can effectively reflect thermal radiation and improve the insulation effect, so it is particularly suitable for the insulation of pipes and equipment with higher temperatures.
3. Non-combustible rockwool pipe
Non-combustible rockwool pipe is made of non-combustible rockwool fiber, which has the properties of high temperature resistance, heat insulation, and sound elimination. It is suitable for various places that require high temperature resistance and insulation, such as petrochemical, electric power, metallurgy and other industries.
4. High-density rockwool pipe
High-density rockwool pipe has higher density and strength, so it has better insulation performance. It is suitable for some places with high requirements for insulation performance, such as freezers, cold storage, etc.
5. Self-adhesive rock wool pipe
Self-adhesive rock wool pipe adds self-adhesive adhesive to ordinary rock wool pipe, so that it can be directly pasted on the surface of the pipe, which is convenient and quick to install. This kind of rock wool pipe is particularly suitable for some complex pipe structures.
6. Special Rockwool Pipe Types
Waterproof Rockwool Pipe: Moisture-repellent treatment makes it ideal for humid or rainy environments.
Flame-Retardant Rockwool Pipe: Maintains low combustion under extreme heat, reducing fire hazards significantly.

In addition, there are some special types of rock wool pipes, such as waterproof rock wool pipes and flame-retardant rock wool pipes. Waterproof rock wool pipes are specially added with water repellent during the production process to form a dense waterproof layer on their surface, which effectively prevents water penetration and is suitable for use in humid or rainy environments. Flame-retardant rock wool pipes use high flame-retardant materials as additives, which can maintain good thermal insulation performance and low combustion rate even under extreme conditions, greatly reducing the risk of fire.
Rock wool pipe is a kind of rock wool insulation material mainly used in pipelines, with many excellent properties and application fields. The following is a detailed introduction to rock wool pipe:

Material characteristics
1. Raw materials and production:
Rock wool pipe uses natural basalt as the main raw material. After high-temperature melting, it is made into artificial inorganic fibers by high-speed centrifugal equipment, and special adhesives and dust-proof oil are added. After heating and curing, it is made into rock wool insulation pipes of various specifications and different requirements. In addition, rock wool can also be compounded with glass wool and aluminum silicate wool to make rock wool composite insulation pipe shell.
2. Physical properties:
Rock wool pipe has the advantages of light weight, low thermal conductivity, good sound absorption, non-flammability, and good chemical stability. Its internal inorganic fiber structure can effectively reduce the heat exchange caused by the temperature difference on both sides of the material, thereby achieving insulation effect.
3. Special functions:
Waterproof rock wool pipe has the special functions of moisture-proof, heat dissipation, and water-repellent. It is particularly suitable for use in rainy and humid environments. The moisture absorption rate is less than 5%, and the water repellency is more than 98%.

Application fields
1. Industrial field:
Rock wool pipe shells are widely used in the insulation of industrial boilers and equipment pipelines in petroleum, chemical, metallurgy, shipbuilding, textile and other industries. Its good thermal insulation performance, machining performance and fire resistance make rock wool pipes widely used in these fields.
2. Construction field:
Rock wool pipes are also used for the insulation of partitions, ceilings and internal and external walls in the construction industry, as well as the insulation of various types of cold and hot pipes and hidden and exposed pipes. Rock wool pipes also perform well in the thermal insulation of pipes in the power, light industry and other industries.

Advantages and characteristics
1. Efficient insulation:
Rock wool pipes have excellent thermal insulation performance, which can effectively reduce heat loss and improve energy utilization efficiency.
2. Environmental protection and safety:
Rock wool pipes are non-combustible materials, do not contain harmful substances such as fluorine and chlorine, have no corrosive effect on equipment, and meet environmental protection and safety requirements.
3. Convenient construction:
Rock wool pipes are easy and quick to construct, especially suitable for the construction of small-mouth straight pipes, which can save construction time and cost.

In summary, s a high-quality thermal insulation material, rock wool pipe has a wide range of application prospects in the industrial and construction fields. Its excellent performance, environmental protection and safety characteristics, and convenient construction advantages make rock wool pipe an important member of the thermal insulation material market.

The conventional sizes of rock wool pipes vary depending on their use and specific needs, but generally include the following specifications:
1. Diameter: The diameter of rock wool pipes ranges widely, from a small 20mm to a large 2000mm. This range can meet the insulation needs of pipes of different diameters.
2. Length: The length of rock wool pipes is usually between 1 meter and 2.5 meters, but it can also be customized according to the specific needs of customers. This flexibility allows rock wool pipes to adapt to pipe insulation projects of various lengths.
3. Wall thickness: For certain types of rock wool pipes such as aluminum foil rock wool pipes, the wall thickness is also an important specification parameter. The wall thickness is generally between 20mm and 50mm, which helps to ensure the insulation effect and mechanical strength of the rock wool pipe.
4. Special specifications: In addition to the above conventional sizes, rock wool pipes can also be customized according to the needs of specific projects. For example, the elbow type rock wool pipe can be set with different elbow angles (such as between 15 degrees and 180 degrees), and the elbow radius can be freely adjusted according to needs. In addition, flange-type rock wool pipes can be used for a variety of nominal diameters, and the nominal pressure range can be customized as needed.
It should be noted that the size selection of rock wool pipes should be based on the specific pipe size, insulation requirements, installation conditions and other factors. When choosing rock wool pipes, it is recommended to consult a professional insulation material supplier or engineer for more accurate advice and solutions.
In addition, as an excellent insulation material, rock wool pipes have the advantages of low thermal conductivity, good insulation effect, high and low temperature resistance, and fire resistance. These characteristics make rock wool pipes widely used in the field of pipeline insulation.
