High Density Polyethylene Pipe -Hualin Pipe Technology

High Density Polyethylene Pipe

Our high-density polyethylene pipes are easy and quick to install and can be connected by hot-melt or electric-melt connection. They also have good negative pressure resistance. The negative pressure resistance of S12.5 series pipes exceeds -0.09MPa. They have a long service life of up to 50 years.

High Density Polyethylene Pipe Manufacturer in China

High density polyethylene pipe is a high-performance thermoplastic pipe made of HDPE resin by extrusion. With its excellent mechanical properties, corrosion resistance and long-term stability, it is widely used in municipal, energy, industrial and other fields. It is an ideal choice to replace traditional metal pipes and concrete pipes.

Key Features of HUALIN High Density Polyethylene Pipe

High density polyethylene Pipe is connected by hot-melt welding and completed in the workshop. Parts that are difficult to connect on the construction site are welded with special electric welding pipe clamps and electric welding packs to ensure welding quality and prevent leakage. If the construction space conditions allow, the whole section can be prefabricated to save construction time. Resistant to chemical corrosion and acid rain; strong flexibility, no damage, impact resistance; can be buried in concrete; earthquake-resistant; suitable for -200℃~800℃ temperature range; wear-resistant, effectively resisting the friction of stones and sand on the pipeline; smooth surface, not easy to clog.

Why Choose Our High Density Polyethylene Pipe?

High-density polyethylene pipes are highly resistant to corrosion against acids, alkalis, salt solutions and various chemical media (such as sulfates and chlorides). No additional anti-corrosion treatment is required when laying underground, which can reduce corrosion maintenance costs by more than 90% compared to steel pipes. By adding antioxidants and ultraviolet absorbers, high-density polyethylene pipes have stable performance in an environment of -40℃ to 60℃ and are not prone to brittle cracking during long-term outdoor use. For example, buried water supply pipes in cold areas use high-density polyethylene pipes to avoid the risk of freezing and cracking at low temperatures.

HUALIN High Density Polyethylene Pipe Applications Explored

HUALIN High Density Polyethylene Pipe are widely used in various industries and play an important role in multiple scenarios. Some common applications include:

1、Municipal engineering field: The core carrier of urban infrastructure, replacing traditional concrete pipes for rainwater and sewage discharge. The smooth inner wall reduces water flow resistance and is resistant to acid and alkali corrosion (such as industrial wastewater discharge).

‌2. Water Conservancy and Agriculture: The preferred choice for efficient irrigation and water conservancy construction, large-diameter high-density polyethylene pipes (such as DN800) are used for reservoir water diversion or irrigation area main canals. They are resistant to water pressure and silt wear, and can reduce leakage losses by 15%-20% compared to concrete channels.

‌3. Industrial field: Corrosion-resistant and highly reliable engineering solutions for transporting solvents and drugs in pharmaceutical factories, resisting corrosion from chemical media, and avoiding contamination of raw materials.

4. Power and communications: Cable protection and underground pipe network construction. The porous high-density polyethylene communication pipe can lay multiple optical cables at the same time. The smooth inner wall reduces threading resistance and is suitable for municipal communication pipe networks and community broadband wiring.

5. Construction and civil use: Flexible application of indoor and outdoor projects. In rural water improvement projects, high-density polyethylene pipes are used as household water supply pipes, which are corrosion-resistant and have safe water quality. In courtyard irrigation systems, high-density polyethylene micro-sprinklers can achieve automatic watering and save manpower.

FAQ

What is the service life of High Density Polyethylene Pipe?

1.Basic life span range
‌ Conventional life span: Under standard working conditions (underground laying, no strong corrosive media), the life span of HDPE drainage pipes is ≥50 years, far exceeding concrete pipes (20-30 years) and metal pipes (15-25 years).

‌ 2.Theoretical limit ‌: Some studies have shown that under ideal conditions (constant temperature, no mechanical damage, and standardized maintenance), the life span can reach ‌70-100 years ‌.
