PE plastic municipal water supply and drainage pipe manufacturer PE underground irrigation water supply pipe

Product Description

1. Product introduction

PE water supply pipe and drainage pipe: PE (polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance, non-toxicity and other characteristics. Because it does not rust, it is an ideal pipe material to replace ordinary iron water supply pipes.

PE water supply pipes comply with national product standards: GB/T13663,1-2017, GBI 13663,2-2018 "Polyethylene (PE) Pipeline System for Water Supply Part 2: Pipe Materials". Polyethylene is an inert material. Except for a small amount of strong oxidants, it is resistant to a variety of chemicals and is not prone to bacterial growth.

As we all know, the reason why steel pipes and cast iron pipes are replaced by plastic pipes is not only because plastic pipes have lower water transportation energy consumption, lower living energy consumption, light weight, small flow resistance, easy and quick installation, low cost, long life, and thermal insulation function, but also because plastic pipes are corrosion-resistant,

It is less likely to breed microorganisms and has better properties than steel pipes and cast iron pipes. The service life of polyethylene pipes is more than 50 years. This has not only been confirmed by international standards and some advanced foreign standards, but also polyethylene has very outstanding low-temperature resistance.

Plastic pipes in my country are developing rapidly and their quality is constantly improving. Among them, polyethylene PE pipes are widely used in building drainage, buried drainage pipes, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly used in urban water supply, urban gas supply and farmland irrigation.

2. PE drainage pipe has characteristics

1. Long service life: Under rated temperature and pressure conditions, PE pipes can be used safely for more than 50 years.

2. Good impact resistance: PE pipe has good toughness and high impact resistance. Heavy objects can directly press through the pipe without causing it to rupture.

3. Reliable connection performance: The strength of the PE pipe hot-melt or electro-fusion interface is higher than that of the pipe body, and the joints will not be disconnected due to soil movement or live load.

4. Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the overall project cost is low.

5. Excellent corrosion resistance: Except for a few strong oxidants, it can withstand the erosion of a variety of chemical media; no electrochemical corrosion.

3. Core performance characteristics

1. Corrosion resistance & long life

Resistant to acid, alkali, salt spray, and chemical corrosion, it is suitable for high-corrosion environments such as chemical industry areas and coastal areas.

The service life is more than 50 years, which is much higher than that of steel pipes and cement pipes (easy to rust and scale).

2. High strength & impact resistance

High ring stiffness, strong underground pressure resistance, and not easy to deform.

It has good flexibility, can adapt to foundation settlement or earthquakes, and has excellent earthquake resistance.

3. Health, Safety & Environmental Protection

It is non-toxic and odorless, complies with GB/T13663,1-2017 and GBI 13663,2-2018 drinking water hygiene standards, and does not breed bacteria.

The inner wall is smooth, the water flow resistance is small, it is not easy to scale, and the water delivery efficiency is high.

100% recyclable, green and environmentally friendly.

4. Low temperature resistance & anti-freeze cracking

Working temperature range: -40°C ~ 60°C, suitable for cold areas (such as northern permafrost zones).

5. Convenient & economical construction

Light weight (only 1/8 of steel pipe), easy to transport and install.

Various connection methods

Hot melt butt joint (large diameter, high strength sealing).

Electrofusion connection (small diameter or complex environment).

Socket connection (commonly used for drain pipes).

Low overall cost: maintenance-free, high construction efficiency and long life.

4. Application fields

1. PE water supply pipe

Municipal water supply: urban tap water main pipes and community pipe networks.

Rural drinking water: safe drinking water project.

Agricultural irrigation: drip irrigation, sprinkler irrigation systems.

Industrial water: fluid transportation in chemical industry, power plants, mines, etc.

2. PE drain pipe

Municipal drainage: rainwater and sewage pipe network.

Building drainage: indoor and outdoor sewage discharge.

Industrial wastewater: treatment of highly corrosive wastewater from chemical industry, pharmaceutical industry, etc.

Road drainage: drainage systems along highways and railways.

5. Installation and maintenance

1. Installation method

Water supply pipe: Priority is given to hot-melt butt joints or electrofusion connections to ensure tightness.

Drainage pipe: commonly used socket connection (rubber ring seal) or hot melt welding.

2. Construction precautions

The trench must be smooth to prevent sharp stones from scratching the pipe.

When backfilling, compact it in layers to prevent the pipeline from deforming under pressure.

Pay attention to the flexibility of the material during low-temperature construction (PE pipe is still better than PVC).

3. Maintenance requirements

Basically maintenance-free, just check the interface regularly.

If damaged by external force, it can be partially replaced and the maintenance cost is low.
