**Introduction**

The **High-Speed Multi-Layer Steel Wire Mesh Skeleton Reinforced Polyethylene Composite Pipe Production Line** represents a cutting-edge advancement in the manufacturing of durable and versatile composite piping systems. Developed by **Anhui Dongchai Machinery Technology Co., Ltd.**, this production line integrates advanced automation, multi-layer extrusion technology, and high-strength steel wire reinforcement to produce pipes that combine the best properties of polyethylene and steel. This article explores the product's features, technical specifications, applications, and the company's expertise in the field.

**Core Introduction**

The production line consists of critical components including a **high-speed extruder**, **precision die**, **vacuum setting table**, **traction unit**, **cutting machine**, and **tipping frame**. These elements work in harmony to create **steel wire mesh skeleton reinforced polyethylene composite pipes** that leverage the high strength of steel and the corrosion resistance of polyethylene. This innovative design ensures the pipes are suitable for demanding applications across industries such as petroleum, natural gas, chemical processing, and more.

Key Highlights:

• High Speed and High Efficiency: Advanced automation technology enables continuous, high-speed production, significantly boosting output and reducing labor costs.
• Multi-Layer Structure: The multi-layer extrusion process allows for customization to meet diverse application requirements.
• Steel Wire Reinforcement: The steel wire mesh skeleton enhances the pipe's compressive, bending, and tensile strength, ensuring stability under extreme conditions.
• Corrosion Resistance: Polyethylene's inherent resistance to chemical corrosion extends the pipe's lifespan in harsh environments.
• Good Flexibility: Despite its strength, the composite pipe retains flexibility, making it adaptable to complex terrains and installation challenges.

**Science Popularization**

Multi-layer steel wire mesh skeleton reinforced polyethylene composite pipes are engineered using a **left-right spiral-wound steel wire mesh** as the reinforcement core. This mesh is embedded within **high-density polyethylene (HDPE)**, with **high-performance HDPE modified adhesive resin** acting as a bonding agent. This structure ensures the steel wire and polyethylene layers are tightly integrated, creating a material that balances mechanical strength with chemical resilience.

The design is particularly effective in applications requiring **high-pressure resistance** and **long-term durability**. For instance, the steel wire mesh prevents plastic deformation under sustained loads, while the polyethylene layer shields against environmental degradation.

**Performance Advantages**

**High Strength and Durability**

• The steel wire mesh skeleton significantly enhances the pipe's **compressive, bending, and tensile strength**. This makes it ideal for high-pressure systems, with a **nominal pressure range of 0.6MPa to 3.5MPa**.
• The composite structure ensures the pipe maintains its integrity over time, even in environments with fluctuating temperatures and mechanical stress.

**Excellent Flexibility**

• The steel wire mesh itself is flexible, allowing the composite pipe to **adapt to complex terrains** without compromising structural integrity.
• This flexibility reduces the need for additional pipe fittings, lowering installation costs and minimizing potential leak points.

**Good Dimensional Stability**

• The steel wire mesh acts as a constraint, reducing the **linear expansion coefficient** of the pipe. This is crucial in environments with extreme temperature variations.
• By minimizing thermal expansion and contraction, the pipe avoids issues like deformation and stress concentration, ensuring long-term reliability.

**Corrosion and Wear Resistance**

• Polyethylene's **chemical inertness** protects the pipe from corrosion caused by acids, alkalis, and other aggressive substances.
• The steel wire mesh also prevents **plastic creep** (slow deformation under stress), further enhancing the pipe's durability under low-temperature or persistent hoop stress conditions.

**Superiority in Installation and Maintenance**

The composite pipes are designed for **easy installation and maintenance**. They can be connected using **electrothermal fusion** or **flange connections**, both of which are well-established techniques in the industry. This ensures **fast and reliable installation**, reducing downtime and labor costs.

During use, the pipes require minimal upkeep. Regular checks for **connection integrity** and **surface damage** are sufficient to maintain optimal performance. These features have made the product a preferred choice in sectors like **oil and gas, agriculture, and marine engineering**.
