Polypropylene Pipes and Its Features


Galvanized pipes, which were first used in the plumbing system in Europe in the 1830s, lost their dominance in the 1960s. As of the 70s, steel pipes began to be used in the supply of clean water, depending on the development in the industry. With the declining demand for steel and galvanized pipe systems, the need for pipes that are modified and diversified with modern technology has opened up the scope for polypropylene group pipes. Standing out by responding to the current needs of the consumer, polypropylene pipes have succeeded in leaving other pipe groups behind in time with their unique features. The use of plastic pipes in plumbing and heating systems has greatly increased in the 2000s due to its cost-effectiveness and reliability.

Ease of transport due to light weight, long service life, smooth structure that does not accumulate rust and limescale, as well as resistance to corrosion are other factors that have brought consumer preferences to the highest level. Polypropylene pipes, which are positioned in the first place with user experience, are divided into three groups based on their resistance to heat, pressure and chemicals:


1) Homopolymer

2) Copolymer

3) Random Copolymer


Homopolymer is used as a raw material in different production areas with its semi-hard, transparent and easily shaped structure. Due to its high chemical resistance, its usage area is quite wide.


Copolymer is softer but with higher impact resistance, it is more common to use than homopolymer raw materials. It is preferred in different production areas with its resistance to cracking and low temperature. It is highly resistant to chemicals and abrasion, but has a structure that is not resistant to heat.


Random Copolymer is preferred more than other pipe types in clean water installations. Compared with the homopolymer, the low melting point and the high resistance level come to the fore. In order to prevent the expansion that may occur as a result of the increase in the elongation coefficient of these pipes in the heating lines, glass fiber reinforced composite ones from the same pipe group should be preferred.


In this direction, EMIRPLAST includes the production of [glass fiber reinforced composite pipe] in its product range, as well as the production of [al foil pipe].
