Introduction

The composite pipe production line represents a cutting-edge solution in modern pipe manufacturing technology. Designed for high-efficiency production of polyethylene composite pipes with steel wire mesh skeletons, this equipment combines advanced engineering with user-centric design. The system integrates a high-speed extruder, precision die, vacuum setting table, traction unit, cutting machine, and full-automatic sealing machine, all controlled by a PLC computer for seamless automation.

Key Highlights of the Production Line

1. Advanced Electrical Components and Heating System

The main engine utilizes international first-line brand electrical appliances, ensuring reliability and performance. The dies and screws are crafted from 40Cr alloy structural steel, offering exceptional durability. The ceramic heating ring features an insulation layer for rapid heating, while incremental rings on the inner and outer walls enhance thermal efficiency. The gear box is equipped with a condenser, ensuring stable and fast discharging speeds.

2. Precision Vacuum System

The vacuum box is constructed from 304 stainless steel, bent and welded in a single process. All internal components are laser-cut, and the spray port is controlled by an intensive frequency converter. The system maintains constant water temperature for optimal cooling, minimizing noise and ensuring a smooth production environment. The disc-type 304 ball valve allows for electrically adjustable crossbars, providing precise control over the manufacturing process.

3. Intelligent Sealing Mechanism

The full-intelligent automatic sealing machine eliminates the need for on-line guards, offering automatic tube unloading and a secure sealing effect. This feature reduces labor costs and enhances operational safety, making it ideal for high-volume production environments.

Scientific Background of the Composite Pipe

The polyethylene composite pipe with steel wire mesh skeleton is a revolutionary material that combines the strengths of high-strength steel wire and high-density polyethylene (HDPE). The steel wire is spirally wound to form a mesh skeleton, which is then bonded with HDPE using high-performance modified adhesive resin. This composite structure provides exceptional mechanical strength, corrosion resistance, and flexibility.

Material and Structural Characteristics

The steel wire mesh composite pipe is composed of high-strength steel wire and thermoplastic polyethylene. The steel wire mesh acts as a reinforcement, significantly enhancing the pipe's structural integrity. The use of high-performance HDPE modified bonding resin ensures a strong bond between the steel skeleton and the polyethylene layers, resulting in a durable and reliable product.

• High-Strength Steel Wire: Provides the necessary tensile strength and load-bearing capacity.
• HDPE Matrix: Offers corrosion resistance, chemical stability, and smooth inner surfaces.
• Modified Adhesive Resin: Ensures a strong composite effect, preventing delamination under stress.

Performance Advantages

This composite pipe overcomes the limitations of traditional steel and plastic pipes while retaining their advantages. Key benefits include:

• Corrosion Resistance: HDPE's chemical inertness prevents rust and degradation in harsh environments.
• Smooth Inner Surface: Reduces friction and enhances flow efficiency for liquids and gases.
• Thermal Insulation: Minimizes heat loss in heating applications.
• Wear Resistance: The steel mesh skeleton prevents abrasion from particulate matter.
• Lightweight: Facilitates easier transportation and installation.

One of the most notable features is the pipe's ability to maintain strength even at elevated temperatures. Unlike pure plastic pipes, which may deform under heat, this composite material exhibits minimal thermal reduction. Additionally, it is resistant to rapid cracking, particularly in large-diameter applications, ensuring long-term reliability.

Production Technology and Flexibility

The production line employs advanced technology to ensure consistent quality. By adjusting parameters such as steel wire diameter, mesh spacing, plastic layer thickness, and resin type, manufacturers can tailor the pipe's properties to meet specific requirements. This adaptability allows the system to produce pipes for diverse applications, including:

• High-Pressure Environments: Suitable for transporting liquids and gases under extreme conditions.
• Corrosive Settings: Ideal for chemical and wastewater treatment facilities.
• Temperature-Extremes: Resistant to both high and low temperatures.

Installation and Maintenance

The steel wire mesh composite pipe is designed for easy installation and maintenance. Its lightweight nature reduces the need for heavy machinery, lowering construction costs. The electric welding joint technology ensures a secure connection, minimizing the risk of leaks. This makes the system ideal for municipal projects, industrial engineering, and infrastructure development.
