These pipes are an appealing alternative for homeowners wishing to upgrade their heating systems because they provide a number of special features and advantages. We’ll go into the details of stitched polyethylene pipes in this post and examine their merits for your house.

Due to its adaptability and durability, stitched polyethylene pipes, or PEX pipes, are a kind of flexible plastic piping that has grown in popularity recently. PEX pipes, in contrast to conventional metal pipes, are not susceptible to corrosion and can endure high temperatures without breaking or leaking. Because of this, they are perfect for use in heating systems, where temperature swings are frequent.

Stitched polyethylene pipes are characterized by their flexibility, which makes installation in confined areas and around corners simple. This adaptability minimizes the chance of leaks and boosts overall system efficiency by making installation easier and requiring fewer extra fittings and connections.

Stitched polyethylene pipes are flexible and incredibly resistant to abrasion and chemicals, which makes them ideal for use in a range of conditions, such as corrosive soils and high-traffic areas. This longevity saves you time and money on maintenance and repairs by guaranteeing that your heating system will continue to operate dependably and efficiently for many years to come.

The ability of stitched polyethylene pipes to expand and contract in response to temperature changes is another crucial characteristic that helps keep cold climates free from freezing and bursts. Because of their adaptability, they are the best option for homes in areas with severe winters, where traditional metal pipes might be more vulnerable to damage.

All things considered, stitched polyethylene pipe installation provides homeowners with an economical and effective way to heat their homes. Long-term energy savings and lower heating costs can be achieved by using PEX pipes instead of conventional metal piping systems because of their strength, flexibility, and corrosion resistance.

When it comes to heating and insulating your home, one key aspect to consider is the installation of stitched polyethylene pipes. These pipes offer unique features that can enhance the efficiency and effectiveness of your heating system. Unlike traditional rigid pipes, stitched polyethylene pipes are flexible and versatile, making them easier to install in various spaces and around obstacles. Their flexibility also reduces the risk of leaks and damage, ensuring a reliable heating system for your home. Additionally, these pipes are resistant to corrosion and chemicals, prolonging their lifespan and minimizing maintenance costs. With their lightweight design and durability, stitched polyethylene pipes provide a cost-effective solution for improving the heating and insulation of your house.

About pipes

Masters actively utilize PEX pipe, which is based on stitched polyethylene, to set up a range of low-temperature heating systems and with coolant maximum heating indicators up to 80–85 °C. The following are the main variations in these products:

  • length;
  • diameter;
  • The thickness of the walls.

Installing heating pipes, as well as networks for water supply and a warm floor system, is less expensive when using this worthy and reasonably priced alternative to plastic pipes that can be quickly and simply installed with your hands and no fancy equipment.

The technology for molecular stitching polyethylene is applied in the production of reach pipes. With the presence of the so-called "form memory" effect, the formation of transverse connections in chains of hydrocarbon molecules guarantees high rates of rigidity, heat resistance, and strength. The stitches percent indicators can vary greatly depending on the production technology used.

  • "A"-peroxidal catalyst at 85-90%;
  • “B” – silanic polymers within 70%;
  • “C” – radiation exposure at 60%;
  • "D" is a nitrogen catalyst within 70%.

Modern stitched polyethylene pipes for water supply and heating systems not only withstand blows and sharply negative temperature exposure, but they also bend without showing creases and retain their original shape even after extensive stretching.

Ways to join the elements

Since PEX pipes are now installed in dedicated bays, it should be easy for you to determine the ideal length on your own and carry out high-quality pipe installation from stitched polyethylene with the fewest possible seams and junctions. The primary typical characteristics of the mounted system and the kind of components used to carry out the connection are taken into consideration when choosing the diameter of the pipeline elements (measured in inches or millimeters).

The installation of the water supply systems and the butt of the heating pipes can be done by hand, without the need for a sophisticated professional tool. Special fittings, corner products, and cranes are used in this process. While there aren’t many different types of fittings, each one has unique qualities that need to be considered when making a decision.

Clothing fittings

Although it falls under the mechanical connection category, the compression type method is not the same as the compression option. Press fitting and squeezing couplings differ in that press fitting creates an insoluble kind of connection with a zang expander. Workplace technology

  • installation of the ring on the pipe;
  • expansion of the bell -shaped part;
  • the fitting is inserted to the extensor;
  • installation of a ring with its clue using the press.

Although the coupling installation on the pipe’s end and the direct pressing method will yield fairly good indications of the connection, the degree of tightness and dependability cannot be guaranteed in the event of a technology breach.

Electric welding

It will be necessary to use special fittings made of PE-80 and PE-100 brand polyethylene for installation work on heating and water supply systems equipped with stitched polyethylene. They have two connecting locations for electrical contacts on the outside, and heating spiral elements inside. Workplace technology

  • stripping the external section of the pipe;
  • the coupling of the coupling to the restrictive part;
  • installation of welding contacts;
  • Welding events.

The type of PEX tube and its diameter and thickness indicators are considered when selecting an operating mode for the welding equipment in order to achieve a long-lasting electric welding connection. This is particularly crucial for the primary system. These days, one of the simplest and most practical options that doesn’t require specialized knowledge is the welded connection type.


This option can be used to connect various types of pipeline systems without the need for welding or threading, and it can withstand the required pressure and vibrational effects. Workplace technology

  • installation of a compressive wrap element;
  • installation of a split ring;
  • dense insert of the fitting;
  • Wrap the nut.

Compression fittings offer exceptional durability and dependability, and they are symbolized by a split ring, a fitting, and a nut. Typically, these fittings are composed of regular food brass, which does not leach zinc. When performing hidden installation, connectors based on a polyphenyl sulfund (PPSU) are a worthy substitute.

Which is better?

It should be mentioned that fittings made of stitched polyethylene should ideally be bought from the same manufacturer as the pipes. The discrepancy between the diameter indicators of products from different manufacturers, even under the same declared sizes, is frequently about 0.5 mm, which significantly complicates the installation of stitched polyethylene pipe. Typically, highly efficient heating networks or water supply systems are organized in an open environment using specialized compression couplings.

The requirement for regular twisting to preserve a high degree of dependability distinguishes the serviced compounds from one another. Temporary mains are organized using an installation technique similar to this.

For the covert installation of systems serving various functions, a compensation mechanism may be employed. Concurrently, all connections of the mounted system are tested for integrity and tightness under maximum pressure, and pipeline networks are finalized in terms of styling and concealment. Electric welding fittings will need to be used for trunk layers with significant diameter.

Installation rules

The least amount of tools will be needed for the self-installation of stitched polyethylene pipes, but the process still requires planning ahead, acquiring the required parts, and considering the characteristics of the material. Significant efforts are made in the formation of any mechanical connection of reasonable quality when pipe made of stitched polyethylene is installed with a very large pipeline diameter and a fairly high system pressure (by hand, without the assistance of professional masters).

A tight connection is achieved through pressure testing and is maintained for the duration of the pipeline’s operation. The pipe must be trimmed at right angles, cleaned, and a chamfer must form according to the installation guidelines. A press-fingering fitting is then placed into the channel itself, and with the aid of a press, the maximum degree of coupling complexity is generated. A criminal special coupling is placed on the lifting area. Today’s most dependable press technology for stitched polyethylene pipes is thought to be reasonably priced and utilized in the installation of water supply and heating systems. This process involves the use of specific, basic devices.

Planting a sleeve and stretching the holes with a dilate that has handy sliding handles is the first iteration of this technique. The fitting is brought to the required diameter and covered in lubricant at the input opening. You can attract a sleeve free of pillage to the fitting with stretch presses by leaving a small gap created by the movement of the press gils to the challenge’s edges.

The usage of fittings provided by a body with a fitting and ring is necessary for the second installation option. A specialized expansion tool is used during the installation process to manipulate the pipe and ring that are installed on the discharge, making it possible to insert the fitting fitting into the bell that is produced. An extra seal ensures that the "form memory" REC effect is present in the pipes.

The installation of stitched polyethylene pipes can significantly improve a home’s insulation and heating system’s efficacy. Many homeowners prefer these pipes because of their many distinctive features.

Let me start by saying that stitched polyethylene pipes are renowned for their longevity and strength. These pipes, which are made of premium materials, resist rust, corrosion, and deterioration over time. This guarantees that, once installed, they will last a long time and require little maintenance, offering dependable insulation and heating for many years to come.

In addition, compared to other piping systems, stitched polyethylene pipe installation is a reasonably simple procedure. Because of their flexibility, existing structures don’t require as many extensive modifications to be maneuvered around obstacles. This reduces disturbances to the home environment and speeds up the installation process.

The superior heat conductivity of stitched polyethylene pipes is one of their main advantages. With their effective heat-transfer capabilities, these pipes guarantee even heating throughout the house. As a result, comfort levels are increased and energy use is decreased because different rooms and floors have more consistent temperatures.

Stitched polyethylene pipes are also very adaptable and can be used for a variety of insulation and heating purposes. These pipes provide dependable performance in a variety of environments, whether they are used for hot water distribution, radiator systems, or underfloor heating. They are a well-liked option for both new construction projects and home renovations because of their adaptability.

To sum up, installing stitched polyethylene pipes offers a lot of advantages to homeowners who want to upgrade their insulation and heating systems. Owing to their robustness, simplicity of installation, effective heat conductivity, and adaptability, these pipes provide a dependable way to attain maximum comfort and energy economy in any house.
