Product Description

Polyethylene gas pipes have emerged as the top choice for gas distribution networks. These pipes, made from advanced polyethylene materials, offer unparalleled advantages: they are lightweight, resistant to corrosion, available in convenient coil lengths, and can be effortlessly installed using heat fusion or mechanical fittings. Since their introduction in the 1960s, PE pipes have consistently demonstrated their reliability and durability.


Donghong Pipe Industry has meticulously engineered a specialized PE pipe tailored for mining applications, crafted from the advanced PE100-RC material. This material represents an evolution of the conventional PE100, offering superior properties.The PE100-RC material enhances critical features such as Minimum Required Strength (MRS), Slow Crack Growth (SCG), Rapid Crack Propagation (RCP), and high melt strength LS. For gas transfer applications, it boasts exceptional anti-corrosion properties, remarkable flexibility, and minimal medium loss, ensuring superior performance in demanding environments.

Connection Method

 

 

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

 

Product Features

 

Anti-corrosion

Polyethylene (PE) is an exceptionally inert material, making it highly resistant to a broad array of chemical media. With a few exceptions for oxidizing agents, there is no need to worry about the corrosive effects of soil and water quality.

 

Good Connection Security
Our pipes are primarily connected through heat fusion butt joints and electrofusion techniques, ensuring joint and pipe material integration. The interface strength surpasses that of the pipe body itself.

 

High Flexibility
With an elongation at break of ≥ 500%, our pipes exhibit exceptional flexibility. This affords them the ability to handle uneven soil settlements and superior seismic performance.

 

Good Impact Resistance

Performing reliably even in low-temperature environments of -20ºC to -40ºC, our pipes resist external impacts effectively, preventing cracks and other damages.

 

Good Cracking Resistance

Our pipes boast excellent resistance to rapid crack propagation (RCP) and slow crack growth (SCG), effectively preventing cracking and crack propagation in low-temperature areas and during installation.

 

Low Friction Coefficient
The smooth inner wall and non-adhesive properties of our pipes ensure high pipeline conveying capacity and reduce pressure loss within the pipeline.

 

Product Advantages
