General Properties of HDPE Polyethylene Pipes
The diameter of HDPE pipes, namely pipes of high-density polyethylene, ranges between 20mm and 800mm, and their pressure ranges between pn 4 (4 atm) and pn 32(32 atm).
HDPE is an abbreviation and stands for the English term High Density Poly Ethylenin; its Turkish equivalent is high-density polyethylene. HDPE is obtained when petroleum derivatives undergo various processes.
You can use drinking water with HDPE pipes. The HDPE pipe system passed many tests in 1950, especially regarding drinking water. As a result of these tests, after the reports showed positive results indicating that HDPE pipes did not harm human health, they were made available for use. Being one of the most widely used types of pipes nowadays, HDPE pipe systems stand out thanks to their economical features, ease of installation, performance efficiency, straightforward jointing method and practicality.
A PE100 pipe is a pipe produced with a raw material called PE100, which is a type of HDPE raw material. This type stands out with higher liquid transportation capacity, especially under high pressure conditions.
The prices of HDPE polyethylene pipes are rather affordable, and the minimum service life of an HDPE pipe is 50 years.
Having a history of 60 years, HDPE pipes have been positively affected by the technological developments the sector has undergone up to date, and they have become one of the most preferred types of pipes. HDPE pipes preserve the general properties of the flowing fluids. Since they prevent moss from forming on their surfaces, they can be easily used in drinking water systems. Due to their chemical properties, they have high resistance to chemicals. Thanks to their flexibility, it is quite easy to bend them on soft grounds and shape them according to the slope. Because of their high elasticity properties, they can be used quite conveniently in regions with frequent seismic activity. They can adapt to the direction of the movement, depending on the direction of the ground movement, and they do not break. The welding and jointing methods of HDPE pipes are very simple. Thanks to their lightness, they are easy to carry and therefore their transportation is affordable.
HDPE Polyethylene Pipe and Fitting Jointing Methods
To join polyethylene pipes or fittings, they are either melted to each other or connected using mechanical fittings. Polyethylene pipes that are left inside the ground can be connected using various fittings, flanges or purpose-developed transition adapters.
The known jointing methods for PE materials are;
- Electrofusion (EF)
- Butt-fusion (Butt Welding)
- Socket Welding
- Flange Connection
Usage Areas of HDPE Polyethylene Pipes
