Polyethylene (PE) Insulated Steel Pipe Production Line

Benefits and Advantages of PE Insulated Steel Pipe Production Line

1. Enhanced Insulation: The PE insulated steel pipe production line enables the creation of pipes with a polyethylene insulation layer. This layer enhances the thermal insulation properties of the pipes, reducing heat loss and improving energy efficiency in various applications.

2. Corrosion Resistance: The combination of polyethylene insulation and steel pipe provides excellent resistance against corrosion. This helps to extend the lifespan of the pipes and reduces the need for frequent maintenance or replacements.

3. Versatility: PE insulated steel pipes can be used in a wide range of applications, including district heating systems, underground pipelines, and industrial processes. The production line allows for customization of pipe dimensions and insulation thickness to meet specific project requirements.

4. High Durability: The production line ensures a strong adhesion between the polyethylene insulation layer and the steel pipe. This results in pipes that are highly durable and resistant to mechanical stress, impacts, and environmental conditions.

5. Cost Savings: PE insulated steel pipes offer long-term cost savings by minimizing heat loss, reducing energy consumption, and avoiding corrosion-related repairs or replacements. Additionally, the efficient production process of the line helps to optimize productivity and minimize production costs.

6. Environmental Friendly: PE insulated steel pipes are considered environmentally friendly due to their energy-saving properties and recyclability of both the steel and polyethylene materials used in their production.

7. Compliance with Standards: The PE insulated steel pipe production line ensures compliance with industry standards and regulations, guaranteeing the production of pipes that meet quality and performance requirements.

Product Description of Polyethylene (PE) Insulated Steel Pipe Production Line

The insulation pipes produced by polyethylene insulation pipe equipment are divided into three layers from the inside out: 

The first layer: working steel pipe layer

Seamless steel pipes, spiral steel pipes, and straight seam steel pipes are selected according to the design and customer requirements. After the steel pipe surface is treated by advanced shot blasting technology, the rust removal grade of the steel pipe can reach Sa2 in GB8923-1988 standard, and the surface roughness can reach R=12.5 microns in GB6060.5-88 standard. 

The second layer: polyurethane insulation layer

It is made by injecting hard polyurethane foam liquid into the cavity formed between the steel pipe and the outer protective layer at one time with a high-pressure foaming machine, Commonly known as "pipe in pipe foaming".

The third layer: high-density polyethylene protective layer

Black or yellow polyethylene plastic pipes prefabricated into a certain wall thickness. 

Its function is to protect the polyurethane insulation layer from mechanical damage, and to prevent corrosion and waterproofing. The insulation layer and anti-corrosion layer are simultaneously coated on the steel pipe, allowing for continuous operation, high efficiency, and low cost. Online shot blasting and rust removal, online spray rust prevention treatment, online fully automatic hydraulic automatic deviation correction machine, high accuracy, stability, and reliability. The pipeline transportation adopts multi roller rubber wheel compression transmission, and the steel pipe transmission is stable and straight. 

Wide range of pipeline production: 448-01000mm.
