Glass Fiber HDPE Tapes for HDPE Pipe Winding

These glass fiber HDPE tapes, precision-engineered for flexibility in pipeline systems, are a revolutionary material in the pipeline industry. They seamlessly marry the uncompromising strength of glass fiber reinforcement with the pliability of HDPE (high density polyethylene), resulting in a composite that is not only robust but also seamlessly integrates with pipe layers.

Product Specifications

Using our custom molds, we can produce Glass Fiber HDPE unidirectional tapes from 0.2mm to 0.45mm thick. For thicker tapes, we laminate multiple layers. The optimal thickness is 0.3mm, with a tolerance of +/- 0.02mm.

THICKNESS 0.2mm – 0.45mm as per customers’ particular requirements
WIDTH 50mm -600mm as per customers’ particular requirements
LENGTH ≤ 4000 meters per roll

Physical and Mechanical Properties

By adjusting the glass fiber content and selecting various grades of raw materials, we manufacture Glass Fiber HDPE unidirectional tapes with different strengths to cater to the diverse needs of our clients.

FIBER WEIGHT CONTENT 40% – 65%
TENSILE STRENGTH 600 – 1000 MPa
TENSILE MODULUS 28 – 30 GPa

Method of Winding

Depending on whether heating is applied, there are typically two winding methods.

Hot Melt Winding

  • It involves heating equipment to melt the Glass Fiber HDPE Tape and tightly adhere it to the pipe surface.
  • Common heating equipment includes electric hot air blowers and infrared heaters.
  • The resulting connection has high strength and excellent sealing properties, making it suitable for harsh environments such as high pressure and high temperature.

Cold Winding

  • It does not require heating equipment, making the construction process simpler and safer.
  • Although the strength of the resulting connection may be slightly inferior to hot melt winding, it has sufficient stability and durability in normal temperature and pressure environments.

The Reinforcement Middle Layer

Regardless of the winding method employed, glass fiber reinforced HDPE tapes are typically utilized as the middle layer in flexible pipes. These pipes generally consist of three layers: the innermost layer features the best sealing properties to prevent leakage of transported liquids or gases to the outer layers during conveyance; the middle layer primarily provides robust structural support to ensure the safety of the pipe under high-pressure conditions; and the outermost layer, which directly interfaces with the external environment, plays the most significant role in resisting corrosion and damage from external factors.
