HDPE Zhejiang Petrochemical 23050
HDPE Zhejiang Petrochemical 23050 Resin
Material Introduction: HDPE Zhejiang Petrochemical 23050 is a PE100‑grade high‑density polyethylene pipe resin. Adopting multi‑modal molecular‑weight distribution design, it delivers excellent long‑term pressure resistance, environmental‑stress‑cracking resistance and favorable processability, widely used in demanding pressure piping systems.
Main Applications
Pressure piping systems
‑ Water‑supply pipes: urban and building potable‑water supply pipelines for safe and reliable drinking‑water transportation. ‑ Gas‑supply pipes: suitable for natural gas and liquefied‑gas transportation with good sealing performance and safety.
Non‑pressure piping systems
‑ Drainage pipes: municipal drainage and industrial wastewater discharge. ‑ Large‑diameter pipes: double‑wall corrugated pipes, solid‑wall conveyance pipes for water‑conservancy projects and seawater‑desalination key national projects.
Other fields
‑ Chemical pipes: resistant to various corrosive liquid and gas media for chemical plants. ‑ Agricultural irrigation pipes: water delivery for agricultural irrigation systems. ‑ Cable protection conduits: protect cables from mechanical damage and chemical corrosion.
