Materials for engineering systems: overview and selection

Materials for engineering systems play a key role in ensuring the reliable and efficient operation of water supply, heating, and sewage systems. The proper selection of pipes, fittings, pumps, and other components determines the lifespan of the entire system, its resistance to loads and external influences. This article examines various types of materials used for the installation and maintenance of engineering systems, their advantages, and disadvantages.

1. Pipes for Engineering Systems

Polypropylene (PPR) Pipes

Polypropylene pipes are widely used in water supply and heating due to their strength, durability, and resistance to corrosion. The main advantages of these pipes:

  • Corrosion resistance. Polypropylene does not corrode, making it an ideal choice for systems in contact with water.
  • Long service life. Polypropylene pipes can last up to 50 years with proper use.
  • Lightweight and easy to install. Thanks to their light weight, these pipes are easy to transport and install.

Copper Pipes

Copper is a classic material used in engineering systems due to its unique properties:

  • Resistance to high temperatures. Copper withstands high temperatures, making it ideal for heating systems.
  • Antibacterial properties. Copper pipes help prevent bacterial growth in water supply systems.
  • Durability. Although copper is more expensive than other materials, it has a long service life and is corrosion-resistant.

Metal-Plastic Pipes

Metal-plastic pipes consist of several layers, giving them the advantages of both plastic and metal pipes. Key features:

  • Flexibility and pressure resistance. These pipes are easy to install, especially in complex water supply system configurations.
  • No corrosion. Metal-plastic pipes are corrosion-resistant, making them durable and reliable.
  • Low thermal conductivity. This reduces heat loss in heating systems.

2. Fittings for Engineering Systems

Fittings are connecting elements used for the installation of pipelines. They can be made of various materials, including plastic, metal, or composite materials.

Polypropylene Fittings

  • Low cost. Polypropylene fittings are a budget-friendly option for engineering systems.
  • Lightweight. Eases installation and transportation.
  • Chemical resistance. Ideal for systems working with aggressive environments.

Brass Fittings

  • Strength. Brass fittings withstand high pressure and temperatures well.
  • Corrosion resistance. Brass does not rust, increasing the service life of connections.

Press Fittings

  • Reliable connections. Press fittings provide reliable pipe connections without threads or welding.
  • Easy installation. Installation is quick and requires minimal tools, which is especially convenient when working with metal-plastic or polyethylene pipes.

3. Pumps for Engineering Systems

Pumps are an essential part of water supply and heating systems. They ensure water circulation in systems, guaranteeing their efficient operation.

Circulation Pumps

  • Energy efficiency. Modern pump models are highly energy-efficient, reducing electricity consumption.
  • Low noise level. New pumps operate almost silently, which is important for residential buildings.
  • Automation. Many pumps are equipped with automatic pressure and temperature control systems.

Centrifugal Pumps

  • High performance. Centrifugal pumps can transport large volumes of water over long distances.
  • Versatility. Used in both domestic and industrial water supply systems.

Conclusion

The choice of materials for engineering systems depends on specific operating conditions, budget, and quality requirements. Polypropylene, copper, and metal-plastic each have unique advantages, making them ideal for various types of systems. Fittings and pumps also play an important role in ensuring the reliability and efficiency of engineering systems.
