Product Description

Polyethylene gas pipes are the premium choice for gas distribution systems. These exceptional pipes are celebrated for their light weight, non-corrosive nature, and availability in convenient coil lengths. Installation is a breeze, achieved through heat fusion or mechanical fittings. Thanks to these outstanding attributes, PE pipes have established themselves as reliable and durable solutions since their introduction in the 1960s.

Shandong Donghong Pipe Industry Co., Ltd. proudly manufactures specialized PE pipes specifically tailored for mining applications. Utilizing the advanced PE100-RC material, an enhanced version of PE100, these pipes offer superior performance.The upgraded PE100-RC material boasts significant improvements in key properties, including high Minimum Required Strength (MRS), exceptional Slow Crack Growth (SCG) resistance, remarkable Rapid Crack Propagation (RCP) resistance, and superior melt strength LS. For gas transfer applications, these pipes offer unparalleled anti-corrosion properties, high flexibility, and minimal medium loss.

Connection Method

 

 

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

 

Product Features

 

Anti-corrosion

Polyethylene (PE) is a remarkably inert material, boasting resistance to a broad spectrum of chemical media. Except for a few oxidizing agents, it completely mitigates concerns about corrosive effects from soil and water quality.

 

Good Connection Security
Our pipes are predominantly connected via heat fusion butt joints and electrofusion. This technique integrates the joints seamlessly with the pipe material, ensuring that the interface strength surpasses the strength of the pipe body itself.

 

High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes exhibit remarkable flexibility. They adeptly handle uneven soil settlement and offer superior seismic performance.

 

Good Impact Resistance

In low-temperature environments ranging from -20ºC to -40ºC, our pipes perform flawlessly. They resist external impacts, preventing cracks and other damages.

 

Good Cracking Resistance

Possessing excellent rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively avert cracking and crack propagation in low-temperature areas and during installation damages.

 

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

 

Product Advantages

Product Description:

• Low density, lightweight, and easy to handle and install.
• Corrosion resistance against various chemical media.
