Polyethylene (PE) pipes and fittings are widely used in buildings for water and gas distribution. Depending on the type of polyethylene, these pipes have different characteristics, including pressure and heat resistance, flexibility, light weight, corrosion resistance and thermal insulation.
PE pipes are divided into two types, double-layer and multi-layer. Double-layer pipes include the inner layer of polyethylene and the outer layer of polypropylene, which is considered to strengthen the structure of the pipe. Multi-layer pipes have 3 or 5 layers and can be used for water and gas distribution inside the building.
Polyethylene connections are also used in three types of couplings, elbow and tee. These fittings are easy to install and remove and are very resistant to corrosion and pressure.
The important applications of polyethylene pipes and fittings include hot and cold water distribution, natural gas and high pressure in natural gas distribution networks, irrigation and sewage systems in agriculture and animal husbandry, refinery distribution, petrochemical industries, dam construction and even in some industrial productions. They are used in the production of packaging and foam tubes.
It should be noted that due to its light weight and high flexibility, polyethylene pipes and fittings are used in environments that require the supply of water or gas to places with long distances. Also, these types of pipes are used in rural and semi-urban water and gas distribution systems, which are mostly underground. Due to high corrosion resistance, these pipes are also used in soil and underground conditions.
In general, polyethylene pipes and fittings are used in many industrial, construction and agricultural applications due to their high corrosion resistance, light weight and high flexibility. The use of these types of pipes reduces costs and increases efficiency in construction and industrial projects due to their lower cost and longer life compared to metal pipes.
