POLYETHILENE PIPES FOR GAS AND WATER

POLYETHYLENE WATER PIPES PE 100

Polyethylene tubes are produced from high density polyethylene PE 100 to SRPS and meet all the requirements of European standard EN 12201. This part SRPS EN 12201 specifies the characteristics of polyethylene pipes (PE 100) for underground applications intended for the transfer of water for human consumption, raw water before processing, drainage and sewage under pressure, sewage systems under vacuum, and water passage for other purposes. Polyethylene pipes are characterized by high flexibility and low specific weight, which makes it easy to transport and easy to install. The long life of these pipes guarantees corrosion resistance, chemical resistance, wear resistance with high internal hydrostatic resistance. Good resistance to crack propagation material guarantees great safety when designing high pressure pipelines.

POLYETHYLENE PIPES FOR GAS PE 100

The gas pipes used in the construction of the pipeline are produced from high density polyethylene PE80 or PE100 (MRS ≥ 8 MPa or MRS ≥ 10 MPa), which guarantees that after 50 years the pipes will suffer the same strain. Production and quality control complies with the applicable domestic standard: SRPS EN 1555. The material is non-toxic, easy to transport and handle. Pipes are flexible and resistant to vibration, seismic impacts and soil movement. A permanent heat load is allowed up to + 60ºC, and at the moment up to + 80ºC. Low pressure losses because the friction coefficient is small. The connection of the pipe is performed (depending on the diameter) by coupling or by welding: electrofusion or insulation. Polyethylene pipes for the supply of gaseous fuels can be laid over and into the ground and under water.

ADVANTAGES OF PE PIPES

– High reliability and proven performance performances make PE an excellent choice, especially with buried pipe systems;

– Resistance to low temperatures – due to its high extensibility, toughness and elasticity, “IZOLIR” PE pipes do not create problems when installing and operating at low temperatures;

– High impact resistance – high resistance to hydraulic shock, fatigue and wear eliminates the need for greater nominal pressures and reduces the value of the investment;

– Comparisons have shown that polyethylene pipes have a higher resistance to abrasion than other materials, making PEs the most desirable material for the transport of soluble materials;

– Excellent hydraulic characteristics (low absolute roughness) – smooth surface and visibility to turbulent fluid flow allow for greater flow;

– Excellent chemical resistance – resistance to a large number of chemical agents; – Weldability – due to good weldability and elasticity, PE pipelines of long length can be connected outside the trench and then laid (which reduces the required width of the trench) and the welded joints will be strong and reliable. A wide range of embedding methods, PE pipes offer installers a number of installation solutions that can provide significant time and cost savings, for example PE pipes are preferred for installations without trench or narrow

– A long life span of min 50 years

– Resistance to UV radiation

– Resistance to the formation of deposits

– Healthyness in contact with food products

– Permissible heat load up to + 60oC, and up to + 80oC at the moment. They are also resistant to low temperatures.

– Pipe color: black, with blue lines Advantages of PE gas pipes

– The use of PE pipes for gas is increasing worldwide. Light weight allows them easy handling, simple, fast and reliable connection. They are flexible. They are extremely chemically resistant and they can also be placed in aggressive soil. They are very resistant to impact even at low temperatures. These tubes do not corrode and have a lifetime of over 50 years. The pipes fully correspond to the SRPS-EN1555, ISO 4437 (DIN8074). The marking of the pipe corresponds to the European norms.
