Difference Between HDPE pipe And Steel Mesh Skeleton Pipe

HDPE pipes are similar in appearance to steel mesh skeleton pipes and have similar uses. Many people still have doubts about how to choose the above two pipelines in actual engineering and how to choose. Today I will introduce the difference between HDPE pipe and Steel Mesh Skeleton Pipe

HDPE Pipe (High-Density Polyethylene)

HDPE pipe is a type of thermoplastic pipe made from high-density polyethylene resin. It is widely used in various industries and is known for its toughness, flexibility, and chemical resistance.

Advantages of HDPE Pipe:

🔹 Excellent flexibility, allowing for easy installation around obstacles and curves.

🔹 High resistance to corrosion, chemicals, and abrasion.

🔹 Lightweight, making it easy to transport and handle.

🔹 Long service life with low maintenance requirements.

🔹 Smooth inner surface, promoting efficient flow and reducing the risk of clogs.

🔹 Resistant to biological growth and scale formation.

🔹 Environmentally friendly, as HDPE is recyclable.

Disadvantages of HDPE Pipe:

🔸 Lower stiffness compared to some other pipe materials, which may require additional support in certain applications.

🔸 Vulnerable to UV radiation, so it needs to be protected or treated for outdoor applications.

🔸 Thermal expansion/contraction can be a concern in extreme temperature conditions.

Steel Mesh Skeleton Pipe

Steel mesh skeleton pipe, also known as reinforced thermoplastic pipe (RTP), is a type of pipe that features an inner thermoplastic liner reinforced with a high-strength steel mesh. The steel mesh provides structural integrity and improves the pipe’s resistance to external loads and pressures. Usually, the thermoplastic liner is made of materials like polyethylene (PE) or polypropylene (PP).

Advantages of Steel Mesh Skeleton Pipe:

🔹 Excellent strength and durability due to the reinforcement provided by the steel mesh.

🔹 High resistance to external forces, such as earth and traffic loads.

🔹 Good corrosion resistance, making it suitable for various environments.

🔹 Lightweight compared to traditional metallic pipes.

🔹 Ease of installation and handling.

🔹 Smooth inner surface, reducing friction and allowing for efficient flow.

Disadvantages of Steel Mesh Skeleton Pipe:

🔸 Higher cost compared to some other pipe materials.

🔸 Limited flexibility due to the rigid steel reinforcement.

🔸 Thermal expansion/contraction can be a concern in extreme temperature conditions.

HDPE Pipe Vs Steel Mesh Skeleton Pipe

1. Manufacturing process

HDPE pipes are produced from PE100 raw materials and extruded through an extruder. The steel mesh skeleton pipe uses high-performance HDPE modified bonding resin to tightly connect the steel mesh skeleton with the inner and outer layers of high-density polyethylene (HDPE). Compared with HDPE pipe, it has higher strength and better flexibility.

2. Construction technology

HDPE pipes can be connected in two ways: thermal fusion and electric fusion.

The pipe fittings used in the steel mesh skeleton pipe are polyethylene electrofusion pipe fittings. When connecting, mainly use equipment electrofusion connection, and the steel wire of the cut section should be sealed with HDPE material to avoid exposure to oxidation and corrosion.
