High-Temperature Resistant Polyethylene HVAC Plastic Pipe Production Line

High-Temperature Resistant Polyethylene HVAC Plastic Pipe Production Line

— Professional Pipe Extrusion Solutions from Qingdao Huashida Machinery

 Introduction

Over the course of two years, Huashida Machinery has overcome 30 major technical challenges to successfully develop and launch a one-step PERT insulated pipe production line with independent intellectual property rights!  

The High-Temperature Resistant Polyethylene HVAC Plastic Pipe Production Line from Qingdao Huashida Machinery is engineered to produce premium-quality polyethylene pipes for heating, ventilation, and air conditioning systems.
These pipes are designed for long-term high-temperature operation (up to 95°C), with excellent pressure resistance, chemical stability, and durability — making them the preferred choice for modern central heating and hot water supply networks worldwide.

Whether for residential, commercial, or industrial applications, our equipment ensures consistent pipe quality, high production efficiency, and reliable performance.

Advantages of the One-Step PERT Insulated Pipe Production Line

• Significantly Reduces Production Costs

• High Level of Automation for stable, efficient operation

• Continuous Production without restrictions on pipe length

• Soft Foam Insulated Pipes can be directly buried underground, requiring smaller trenches

• Excellent Mechanical Performance

• Pipes are waterproof, chemical-resistant, and the inner pipe is oxidation-free

• Pipes can be coiled and transported in rolls, greatly reducing the need for pipe joints

• Lower Construction Costs

• 
  

  Product Applications

  The soft insulated pipes produced by this equipment are lightweight, flexible, and can be coiled, making transportation and installation convenient.
  With fewer joints, excellent toughness, and high durability, they are particularly suitable for secondary network pipelines in central heating systems and serve as an ideal replacement for underground secondary steel insulated pipes.
