About HDPE pipes, and raw materials
HDPE- High Density Polythylene - High pressure polyethylene pipes are the most widely used type of clean water pipes.
HDPE pipes can be used in the temperature range of -40 C to +60 C and the working pressure varies depends from usage. Typical standard values are measured in PN (Nominal Pressure) and can be up to PN20 or 20bars. HDPE pipes are classified into PE100 and PE80 depending on the material used.
Comparison of HDPE, MDPE and LDPE
Of polyethylene
- High density polyethylene (HDPE),
- Medium density polyethylene (MDPE)
- Low density polyethylene (LDPE). The scope of application varies depending on the density.
The density designation used to describe these types of plastics is a way for polymer molecules to interact with each other. Polymers have a tighter density than HDPE, which makes them more resistant to compression. The density of HDPE can range from 0.93 to 0.97 g / cm³. HDPE material is resistant to chemicals and UV rays.
Therefore, it is widely used in water, gas and urban water supply canals.
MDPE is a type of polyethylene whose density varies from 0.926 to 0.940 g / cm³. It is less sensitive than HDPE. Resistance cracking is better than HDPE. MDPE is commonly used in gas pipelines, fittings, sacks, film strips, packaging and bags.
LDPE has a density range of 0.91 to 0.94 g / cm³ and is softer and has a softer texture than HDPE. It is widely used in the manufacture of various packaging, pipes, pipes, plastic parts, plastic bags and nets, and various laboratory equipment. Its most common uses are plastic bags and nets.
What is the SDR scale?
Advantages of HDPE pipes
- Can be used for drinking water.
- High chemical resistance
- Due to its high frequency characteristics, it is suitable for use in areas with high seismic loads. It does not crack depending on the direction of traffic.
- Easy to weld and assemble
- Easy to transportv. Environmentally friendly.
- Does not corrode
- Do not multiply microorganisms
