Introduction
PE pipes and HDPE pipes both contain PE, but are they the same type of pipes? Are there any differences between PE pipes and HDPE pipes? In fact, HDPE pipes are a type of PE pipe, but there are still some distinctions between them. Let’s delve into the specific differences.
Differences between HDPE Pipes and Regular PE Pipes
When comparing HDPE pipes and PE pipes for strength, consider factors like manufacturing materials, thickness, and general quality. The strength of polyethylene pipes depends on the type of PE pipes, as highlighted earlier. HDPE pipes, with flexibility and the ability to bend into any shape, exhibit considerable durability. Properly connected, they demonstrate excellent impact resistance, making them robust.
Additionally, HDPE pipes have low thermal conductivity, maintaining normal operating temperatures even when influenced by external factors. They aid in controlling condensation, requiring adequate insulation for certain fluids. Unlike regular PE pipes, HDPE pipes resist rust and withstand internal pressure, ensuring reliable use. Regardless of environmental conditions, HDPE pipes maintain initial flow rates with minimal financial effort.
Differences in Material between HDPE Pipes and PE Pipes
Polyethylene (PE) pipes, a general term for thermoplastic pipes made from ethylene gas, come in various types. These include ultra-low density, low density, cross-linked, ultra-low molecular weight, high molecular weight, medium density, ultra-high molecular weight, chlorinated, and linear low density.
HDPE pipes, representing a type with higher density than basic pipes, are less flexible due to higher melting and impact points. During manufacturing, companies may add carbon black or other colors to resist UV radiation.
HDPE pipes with three bends, two bends, or a single bend can be obtained based on project design. The structure of received HDPE pipes varies based on slope direction and field length.
Understanding HDPE
HDPE is a high-crystallinity, non-polar thermoplastic resin. Non-toxic, tasteless, and odorless, HDPE is a white granular material with a melting point around 130℃ and a relative density of 0.941 to 0.960. It exhibits good heat and cold resistance, excellent chemical stability, high rigidity, toughness, and good mechanical strength. Dielectric properties and resistance to environmental stress cracking are also good. The melting temperature ranges from 120 to 160℃. For larger molecular materials, the recommended melting temperature range is between 200 and 250℃.
High-density polyethylene, a white powder granular product, is non-toxic, tasteless, with a density ranging from 0.940 to 0.976 g/cm3. It has a crystallinity of 80% to 90%, a softening point of 125 to 135℃, and can be used at temperatures up to 100℃. Hardness, tensile strength, and creep resistance are superior to low-density polyethylene. It has good abrasion resistance, electrical insulation, toughness, and cold resistance. However, its insulation is slightly inferior compared to low-density polyethylene. It exhibits good chemical stability, insolubility in organic solvents, and resistance to corrosion. The film has low permeability to water vapor and air, with low water absorption. Aging resistance is poor, and environmental cracking resistance is not as good as low-density polyethylene, necessitating additives for improvement.
