HDPE Hollow Bar: Material Properties, Applications, and Custom Machining
An HDPE hollow bar is a semi-finished polyethylene product widely used for machining custom HDPE components. It is typically produced from high-quality PE100 material, offering excellent mechanical strength, chemical resistance, and long service life.
HDPE hollow bars are commonly used to manufacture flanges, bushings, sleeves, reducers, and other custom HDPE fittings for industrial and pipeline applications.
What Is an HDPE 厚壁管?
An HDPE hollow bar is a thick-walled cylindrical polyethylene product with a central bore. Unlike standard HDPE pipes, hollow bars are designed specifically for CNC machining and custom fabrication, rather than direct pipeline installation.
The controlled dimensions and uniform material structure make HDPE hollow bars ideal for precision processing.
Material Properties of HDPE Hollow Bar
HDPE hollow bars made from PE100 material offer excellent physical and chemical performance:
-
High tensile strength and impact resistance
-
Excellent corrosion and chemical resistance
-
Low moisture absorption
-
Smooth internal structure for machining
-
Long-term stability under pressure and load
These properties make HDPE hollow bars suitable for demanding industrial environments.
Common Sizes and Specifications
HDPE hollow bars are available in various dimensions to meet different machining needs.
Typical specifications include:
-
Material: PE100
-
Outer diameter: Customized
-
Inner diameter: Customized
-
