composite pipe production line-Anhui Dongchai Machinery Technology Co., Ltd.|High-Speed Automation&Low Energy Consumption

Product Introduction

The composite pipe production line represents the latest advancements in industrial automation and material science. This high-speed production system integrates a high-speed extruder, precision die, vacuum setting table, traction unit, cutting machine, and a full-automatic sealing machine. The entire line is controlled by a PLC computer, ensuring high automation, safe operation, and humanized design. Key features include high-speed output, low energy consumption, ease of operation, and a long service life, making it ideal for producing steel wire mesh skeleton reinforced polyethylene composite pipes.

Key Highlights of the Production Line

Highlight 1: Advanced Main Engine and Heating System

The main engine utilizes international first-line brand electrical appliances, with 40Cr alloy structural steel for dies and screws. The ceramic heating ring is wrapped with an insulation layer for fast heating, and both inner and outer walls are equipped with incremental rings. The gear box features a condenser, ensuring stable and rapid discharging speeds.

Highlight 2: Precision Vacuum and Cooling System

The vacuum box is constructed from 304 stainless steel, bent and welded in one piece. Internal components are laser-cut, and the spray port is controlled by an intensive frequency converter. The system maintains constant water temperature, ensuring low noise and efficient cooling. A disc-type 304 ball valve allows electrically adjustable crossbars for optimal performance.

Highlight 3: Full-Intelligent Sealing Machine

The full-automatic sealing machine eliminates the need for on-line guards, enabling automatic tube unloading and a reliable sealing effect. This reduces labor costs and enhances production efficiency.

Science Popularization: Understanding the Composite Pipe

Polyethylene composite pipes with a steel wire mesh skeleton are a revolutionary material in modern engineering. They utilize high-strength steel wire, spirally wound left and right, as the reinforcement. The matrix is high-density polyethylene (HDPE), and high-performance HDPE modified adhesive resin ensures a strong bond between the steel wire skeleton and the inner/outer HDPE layers. This combination results in a pipe that is both durable and lightweight, suitable for demanding environments.

Material and Structural Characteristics

The steel wire mesh composite pipe is composed of high-strength steel wire and thermoplastic polyethylene. The steel wire mesh significantly enhances the pipe's structural integrity. High-performance HDPE modified bonding resin ensures a seamless connection between the steel wire skeleton and the HDPE layers, creating an excellent composite effect.

• High-strength steel wire: Provides exceptional tensile and impact resistance.
• HDPE matrix: Offers corrosion resistance, chemical stability, and smooth inner surfaces.
• Modified adhesive resin: Ensures strong adhesion between components, preventing delamination.

Performance Advantages

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

• Corrosion resistance: Resists chemical degradation in harsh environments.
• Smooth inner surface: Reduces flow resistance and prevents scaling.
• Thermal insulation: Maintains temperature stability for fluid transport.
• Wear resistance: Ensures long-term durability under high-pressure conditions.
• Lightweight: Simplifies installation and reduces construction costs.

Notably, the pipe's strength increases with temperature, and it exhibits minimal deformation compared to pure plastic pipes. It is also resistant to rapid cracking, especially in large-diameter applications.

Production Technology and Flexibility

The production line employs advanced technology to ensure stable product quality. By adjusting parameters such as steel wire diameter, mesh spacing, and plastic layer thickness, the system can tailor the pipe's properties to meet specific requirements. This flexibility allows the production of pipes with varying pressure, temperature, and corrosion resistance capabilities.

Installation and Maintenance

Steel wire mesh composite pipes are ideal for high-pressure transportation environments, such as liquid and gas conveyance. Their lightweight design simplifies installation, reducing construction costs. Electric welding joints ensure a mature and reliable connection, minimizing leakage risks. The system's durability and ease of maintenance further enhance its appeal in industrial and municipal applications.
