HPDE, PVC and PP: Key materials for piping systems

Plastic pipelines are widely used in both industrial and domestic applications due to their strength, durability and ease of installation. The three most popular materials used in modern piping systems are HPDE (high density polyethylene), PVC (polyvinyl chloride) and PP (polypropylene). Each of these materials has unique properties that make them suitable for different applications.

HPDE (High Density Polyethylene)

HPDE (High-Density Polyethylene) is a highly resistant, flexible and durable material widely used in water, wastewater and gas piping systems.

Key benefits of HPDE:

• Resistance to chemicals - not afraid of corrosion and aggressive materials.
• Flexibility - allows the installation of long sections of pipe without joints, reducing the risk of leaks.
• Resistance to impact and temperature variations - works well in both cold and heat.
• Environmentally friendly - easily recyclable and environmentally friendly.

Adaptation:

• Water supply and wastewater systems
• Gas pipelines
• Industrial pipelines
• Irrigation and drainage systems

PVC

PVC is one of the oldest plastic piping materials, with a high resistance to chemical compounds and mechanical stress.

The main advantages of PVC are:

• Resistance to chemicals - does not degrade when exposed to acids and salts.
• Strength and rigidity - low deformation, making it suitable for high-pressure systems.
• Low weight - facilitates transport and installation.
• Cost-effectiveness - A cheaper alternative to metal pipes.

Adaptation:

• Sewage and storm water drainage
• Drinking water supply systems
• Cable protection tubes
• Industrial piping systems

PP (Polypropylene)

PP (Polypropylene) is a versatile plastic material with high temperature and chemical resistance. It is often used in both cold and hot water.

Key benefits of PP:

• High temperature resistance - can be used in hot water supply systems.
• Chemical stability - not afraid of acids, alkalis and other aggressive chemicals.
• Low weight and easy installation - Ideal for a wide range of piping applications.
• Greening - low environmental impact and recyclable.

Adaptation:

• Cold and hot water supply
• Industrial pipelines
• Chemical industry
• Food and pharmaceutical industry

Which material to choose?

Each of these materials has its own advantages, so the choice depends on the requirements of the specific project:

• For flexibility and high impact resistance, choose HPDE.
• For cost-effectiveness and rigidity - PVC will be the best option.
• For resistance to high temperatures and chemical compounds - PP is the most appropriate choice.

Taking these features into account, you can choose the most suitable solution for your infrastructure or domestic piping project.
