 POLYETHYLENE PIPING FOR WATER CONDUCTION

Polyethylene is a polymer that is used extensively in the manufacture of containers, bags, to make containers and in pipes, among others. It is one of the most common plastics used worldwide, especially for the low cost it represents.
Polyethylene was first discovered in the late 19th century, in 1898, by the German chemist Hans von Pechmann, by accident. In the 1930s, two British scientists synthesized it in the way we know it today.

Physical properties
Polyethylene is a thermoplastic polymer consisting of long chains of hydrocarbons. Depending on crystallinity and molecular weight, a glass transition and melting point may or may not be observable. The temperature at which this occurs varies strongly with the type of polyethylene. For common commercial grades of medium and high density polyethylene, the melting point is typically in the range of 120 to 130 ° C (248 to 266 ° F). The commercial low density polyethylene melting point typically is 105 to 115 ° C (221 to 239 ° F).

Chemical properties
Most low, medium and high density polyethylene grades have excellent chemical resistance, which means that they are not attacked by strong acids or strong bases. It is also resistant to mild oxidants and reducing agents. The polyethylene is slowly burned with a blue flame that has a yellow tip and gives off a paraffin smell. The material continues to burn with the removal of the flame source and causes a drip. Polyethylene (other than cross-linked polyethylene) generally can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene.

Today all these concepts serve as a reference to know a little more about this polymer. In the manufacture of pipes also mixes with other compounds such as anticraking, which gives greater resistance to high and low temperatures, either high or low density polyethylene pipes are being used worldwide for driving Water, passing through the agricultural sector until reaching the industrial and residential sector.

In abcbricoten.com Drip Irrigation Shop, we sell low density and high density polyethylene pipes of different diameters.

PROPERTIES OF POLYETHYLENE TUBE

Polyethylene pipes present variable advantages compared to those made with other traditional materials. In general, they can be specified as:

* TOILETS

* INSIPIDAS

* ATOXICAS, complying with current sanitary regulations.

* INALTERABLES to the action of aggressive terrain, even of soils with high lime levels of dangerous infiltrations.

* INSOLUBLES

* RESISTANT to most chemical agents, such as alkalis, oils, alcohols, detergents, bleaches, ether, etc. However, in applications for driving these agents check their behavior in UNE Standards 53.390 and 53.405.

The tube walls can be considered hydraulically smooth and provide minimal resistance to fluid flow, resulting in lower head losses than traditional material piping.
