General Properties of HDPE Polyethylene Pipes
HDPE pipes, or High-Density Polyethylene pipes, have diameters ranging from 20mm to 800mm and pressure ratings ranging from pn 4 (4 atm) to pn 32 (32 atm).
HDPE is an abbreviation for High-Density Polyethylene, which is obtained through various processes involving petroleum products.
HDPE pipes can be used for conveying drinking water. HDPE pipe systems underwent numerous tests, especially for drinking water conveyance, since 1950. Following positive results in all tests confirming that HDPE pipes pose no harm to human health, they were made available for use. Today, HDPE pipe systems are among the most widely used due to their economic feasibility, ease of transportation, performance efficiency, easy assembly, and practicality.
PE100 pipes are a derivative of high-density polyethylene raw materials, produced with PE100 raw material. This product stands out particularly in higher pressure classes due to its increased liquid conveying capacity.
HDPE polyethylene pipes are also very cost-effective, with a minimum lifespan of 50 years.
With a history spanning 60 years, HDPE pipes have benefited from technological advancements and have become one of the most preferred pipes today. HDPE pipes maintain the general characteristics of the fluids flowing through them. Due to their non-adhesive inner surfaces, they can easily be used in drinking water systems. They exhibit high resistance to chemicals due to their chemical properties. Installation on sloped terrains and adapting to the slope is simple due to their flexibility. Thanks to their high elasticity, they are comfortable to use in areas with frequent seismic movements. They can orient themselves according to the direction of movement during ground movements and do not break. The welding and joining methods of HDPE pipes are very simple. Their lightweight makes them easy to transport, thus making transportation inexpensive.
Joining Methods for HDPE Polyethylene Pipes and Fittings
Polyethylene pipes or fittings are connected by either melting them together or using mechanical fittings. Various fittings, flanges, or transition adapters developed for purposes other than polyethylene can be used for pipes other than polyethylene.
Known joining methods for PE materials include:
Electrofusion (EF) Butt Fusion (Socket Fusion) Socket Welding Flanged Connection
Applications of HDPE Polyethylene Pipes
In clean water (drinking water) pipelines In pressurized water pipelines In natural gas pipelines In drinking water treatment plants For the conveyance of solid materials For the transportation of solid wastes For the transportation of chemicals In water cooling pipelines In marine discharge In connecting lines between main trunk lines and distribution networks.
