Polyethylene Pipes For Gas Supply

Polyethylene pipes of PEKPIPE DMCC are suitable for gas supply since they reduce cost and time of running projects all over the country.

The very first usages of plastic pipes return to 1950 years. They are now applied in different fields like: water & chemical transmission, heating and cooling fluid transmission, fire systems, gas and compressed air transmission under/on the ground. One of the first applications of polyethylene (average density) has been gas transmission since 1960. Currently over 90% of gas pipelines of the U.S and Canada are made of plastic which 99% of that is made of PE. Today Gas transmission Polyethylene pipelines are widespread all over the world and not only in northern America.

Advantages :

Easy connecting :

Polyethylene pipes can be welded together so that the joins are as strong as the pipes and in some cases even stronger. Since the common drawback of under pressure pipelines is the fitting place, it can be concluded that polyethylene has stronger fittings in comparison with other materials.

Flexibility:

Polyethylene Pipes are bendable up to 25 times the pipes diameter. This property permits reduction in number of fittings and justifies its applications in earthquake prone areas.

Installation advantages:

Being flexible and leak proof leads to unique installation methods which technically and economically explain polyethylene pipes replacement with steel pipes. it also remarkably saves a lot of time and cost.

Resistance to corrosion and chemicals: Polyethylene pipes are significantly resistant to chemicals and active compounds of gas and chemicals.

Longer Lifetime Potentials, Durability And Cost Reduction:
Service life of PE pipes is estimated between 50 to 100 years. it implies reduction in long-term replacement cost. On the other hand installation and maintenance costs of this product are much less than others.

Standards And Tests:

Tests for the quality control of gas transmission pipes are categorized in 3 sections:

Before Release Tests (BRT) :

Tests done on each batch of products before they are released to the market to ensure their excellence. Process Verification Tests (PVT): Tests done on materials or components of production in certain intervals to evaluate quality and integrity of production line.

Typical tests (TT):

Tests done on materials, components of product and system capability to approve achievement of desired standards.
