Advantages of HDPE Pipes

HDPE pipes with a history of 60 years of technological developments that have positively influenced and until today has become one of today's most preferred tube.
• HDPE pipes; It maintains the general properties of the fluid inside.
• HDPE pipes; moss on hold due to the inner surface can be used in drinking water systems.
• HDPE pipes; Due to its chemical nature, it has a high resistance to chemicals.
• HDPE pipes; To take shape and slope of the sloping terrain by laying is very simple due to be flexible.
• HDPE pipes; Due to its high elasticity properties, for use in areas where a lot of seismic activity is very comfortable. It can orient itself according to the direction of movement of ground motion and does not break.
• HDPE pipes; Other types of pipes
• HDPE pipes; welding and assembly methods are very simple.
HDPE pipes; Easy to carry because of the weight and thus shipping is cheap.
• HDPE pipes; It is highly resistant to acids and alkalis. Only damaged by nitric acid.
• HDPE pipes; Environmentally Friendly.
• HDPE pipes; Are not affected by underground, there is no refractive properties.
• HDPE pipes; it do Not conduct electricity.
• HDPE pipes; a good level of friction, wear and has a rustproof.
• HDPE pipes; It is strong against microorganisms.

Thermal Expansion

One of the difference of the expansion coefficient of the metal pipe to the metal pipe P is it is 10 times larger . That means more expansion and contraction will occur.
Long-term use would be by limiting the temperature in the pressure pipe. This is usually 60 ° C t. Use of pressure for different temperatures are listed in the following table;

Thermal Expansion / Contraction Effects

Due to the change pipe and welded seams temperature stresses can easily meet. Totally it is not necessary to use a system expansion or expansion in PE.
PE 100 pipe expansion coefficient is higher than other materials need to be aware of the following;
* PE 100 Pipes that will be exposed to a certain temperature to be rejuvenated, will make snake like movements or will put pressure on the fixed point.
* Joints in the HDPE pipe connection is required to connect a methanic playing against it.
