Main Applications of Borouge HDPE HE3490-LS-H

1. Pressure pipeline system

Drinking water transportation. Due to its good hygienic properties, Borouge HE3490-LS-H will not pollute the water quality and fully meets the strict standards for drinking water transportation. At the same time, it has excellent corrosion resistance and environmental stress cracking resistance, which can maintain the integrity and safety of the pipeline during long-term drinking water transportation and ensure stable water supply.
Natural gas transportation. In the field of natural gas transportation, the strength, sealing and aging resistance of pipeline materials are extremely high. Borouge HE3490-LS-H can withstand the high pressure during natural gas transportation with its high strength, good resistance to rapid crack propagation (RCP) and resistance to slow crack growth (SCG), effectively prevent pipeline rupture and leakage, and ensure the safety and stability of natural gas transportation.
Pressure sewage pipeline. Sewage usually contains various corrosive substances, which is a huge test for the corrosion resistance of pipeline materials. The material can resist the erosion of chemicals such as acids and alkalis in sewage, ensure the normal operation of pressure sewage pipelines, and reduce maintenance and replacement costs.

2. Industrial applications. In the industrial field, it is often necessary to transport various corrosive or high-temperature media. The HDPE HE3490-LS-H resin can be used to manufacture industrial pipelines with its good chemical stability and thermal stability, and transport media such as chemical raw materials and industrial wastewater to meet the special needs of industrial production processes.

3. Pipeline repair and lining. In pipeline repair projects, this material can be used as a lining material. HE3490-LS-H has good flexibility and processability, and can be easily installed inside the old pipeline to form a new protective layer, improve the pressure resistance and corrosion resistance of the old pipeline, extend the service life of the old pipeline, and reduce the construction difficulty and cost.

4. Marine drainage pipelines. The marine environment is complex and harsh, with many unfavorable factors such as high salinity, seawater scouring, and wave impact. Borouge HDPE HE3490-LS-H resin has excellent seawater corrosion resistance and impact resistance, and can be used stably for a long time in the marine environment. It is suitable for marine engineering fields such as marine drainage pipelines and seawater desalination plant pipelines.

Performance Advantages

Excellent pressure resistance. As a PE100 grade material, HDPE HE3490-LS-H has extremely high pressure resistance and can withstand a nominal pressure of up to 10MPa. It is suitable for various high-pressure pipeline systems and effectively ensures the safe operation of pipelines under high-pressure conditions.
Excellent crack resistance. It has good resistance to slow crack growth (SCG) and rapid crack propagation (RCP). During the long-term use of the pipeline, even if small cracks are generated due to external stress or environmental factors, the material can prevent the further expansion of the cracks and avoid sudden rupture of the pipeline, greatly improving the reliability and safety of the pipeline system.
Good processing performance. The moderate melt flow rate and bimodal molecular weight distribution make it have excellent processing performance. In common processing technologies such as extrusion, injection molding, and blow molding, it can be easily processed into products of various shapes and specifications, and the processing process is stable and the production efficiency is high, which can meet the needs of large-scale industrial production.
Long service life. With its stable chemical structure, good weather resistance and anti-aging properties, under normal use conditions, pipes and other products made of this material can have a service life of up to 50 years or even longer, greatly reducing long-term use costs and maintenance costs.
Sanitary and environmentally friendly. Borouge HE3490-LS-H HDPE complies with relevant health standards and will not release harmful substances in application scenarios involving human health such as drinking water transportation, which is harmless to the environment and human body. At the same time, the material is recyclable, which conforms to modern environmental protection concepts and helps reduce environmental pollution and resource waste.
