PE PIPE

Product

PE PIPE

PE pipes can be constructed and applied in various fields such as waterwork, agriculture,
leisure industry, industry, wire piping, dirty/waste water treatment, seawater, mining.

PE PIPE

Features of PE pipes

Features 01

Chemically stable

Polyethylene is resistant to corrosion by acids, alkalies, and salts and PE pipes are not covered with marine algae or germs such as bacteria.

Features 02

Lightweight

The light weight of the PE pipe enables convenient delivery and handling, while also making installation easy.

Features 03

Sanitary

Because the PE pipe does not contain iron or other materials that are easily released, the purity of the content is maintained. The PE pipe does not cause a change in the taste of water. It's the best pipe to use as a drinking water supply pipe.

Features 04

Joint characteristics

Screws or thermal fusion methods are used for rapid and superior piping installation.

Features 05

Corrosion-resistant

Polyethylene is resistant to corrosion by seawater, wetlands or electrical currents.

Features 06

Flow Characteristics

The PE pipe has slick inner walls, which help to minimize the loss of head of fluid and prevent pipe blockage.

Features 07

Impact-resistant

The PE pipe has high resistance to external impact due to its material properties.

Features 08

Flexible

Curved pipes do not need to be used at curves with smaller angles, and the flexibility of the PE pipe is maintained even at low temperatures, which makes jobs easier.

Features 09

Cold-resistant

The physical properties of PE pipes stay the same even when exposed to temperatures as low as - 80°C, and PE pipes will never freeze and burst.

Features 10

Cost-efficient

The material costs and maintenance costs (e.g.,defect repair cots) are low.

PE PIPE

Use of PE pipes

Waterwork use

Water and drainage pipes, water feed pipes, fire hydrants
Agricultural use

Irrigation, agricultural waterways for reclaimed land, cultivated land, etc.
Leisure industry use

Water and drainage pipes, sprinklers at golf courses and pools, etc.
Industrial use

Water and drainage pipes with chemical resistance, which is required at chemical, food, petrochemical, alkali, steel and pulp manufacturers and hospitals, etc.
Wire pipe use

Wire protection tubes in buildings for underground line protection.
Dirty/waste water (sewage) treatment use

Wastewater-intercepting drains at terminal disposal plants dealing with domestic sewage, human excreta treatment plants, livestock wastewater treatment plants, landfills and places that treat other domestic sewage
Seawater use

Pipes for seawater lead-in and discharge in fish and shellfish aquaculture on land
Mining use

Air duct pipes and groundwater outflow pipes in the mines, pipes for transporting lumber, aggregate, and ore
