Advantages of using in heating systems polypropylene
Consider the advantages of a pipeline made of polypropylene in comparison with systems made from other materials:
- Reduction to the minimum value of heat loss due to high heat conductivity.
- Relatively not high cost of materials.
- Simplicity and reliability of welding connection materials, as well as ease of operation with them during installation and repair.
When using polypropylene materials for heating systems, it should immediately be understood that a simple polypropylene pipeline, subject to high temperatures, can deform or change its dimensions.
In this regard, it is necessary to use reinforced polypropylene pipes for heating, rather than a conventional pipeline made of polypropylene.
Varieties of polypropylene reinforced pipelines
The production of reinforced pipelines divides them into five main varieties. In order to understand what better use of polypropylene pipelines for heating, consider the types:
- Polypropylene systems, which are reinforced with a continuous aluminum sheet. In fact, the material is a one-piece aluminum sheet, which is applied to the outer surface of a polypropylene pipeline. When installing the system with this reinforcement method, this layer is cut at a distance of 1 mm from the edge.
- Pipelines reinforced with aluminum sheet. Aluminum sheet produces reinforcement, in the middle or closer to the inner diameter, if viewed in section section. This type of pipeline during installation does not require preliminary preparation.
- With perforated aluminum sheet reinforcement. The reinforcement process takes place on the outer surface of the polypropylene with a perforated sheet of aluminum. When installing these materials, it is necessary to cut 1 mm of reinforcement material.
- Polypropylene pipelines with composite reinforcement. This method is based on the reinforcement of the polypropylene system due to the composite material, a mixture of glass fiber and polypropylene( polypropylene-composite material( a mixture of fiberglass with polypropylene) - polypropylene).
- Reinforcement of polypropylene pipe with fiberglass. The type of pipeline in which the outer and inner surfaces are made of polypropylene with an inner interlayer of fiberglass, this type of pipe does not require pre-treatment during installation.
On which reinforced polypropylene pipes to stop the selection?
When using a pipeline with external reinforcement, pretreatment is a disadvantage, as labor and material inputs are required. Therefore, the use of polypropylene pipes for heating reinforced with fiberglass is optimal. Since no additional labor is required in the form of pretreatment, it is also not an unimportant factor, is the maximum strength indicators that are associated with the minimum indices of linear expansion.
The photographs show the consequences of neglect when selecting and installing heating pipes that are not suitable for this purpose.
