Product Description

Polyethylene gas pipes represent the pinnacle of excellence for gas distribution systems. Distinguished by their lightweight design, resistance to corrosion, and the convenience of being available in coiled lengths, these pipes are engineered for ease of installation through heat fusion or mechanical fittings. Since their debut in the 1960s, PE gas pipes have become synonymous with reliability and durability, setting the industry standard.

At Shandong Donghong Pipe Industry Co., Ltd., we are proud to produce highly specialized PE pipes, crafted explicitly for mining applications. Our pipes are engineered using the advanced PE100-RC material, an enhanced version of the well-regarded PE100. This material ensures exceptional performance and superior longevity.The advanced PE100-RC material offers remarkable enhancements in critical attributes. It features high Minimum Required Strength (MRS), outstanding resistance to Slow Crack Growth (SCG), impressive Rapid Crack Propagation (RCP) resistance, and superior melt strength LS. Ideal for gas transfer applications, these pipes demonstrate exceptional anti-corrosion properties, high flexibility, and negligible medium loss, delivering unmatched performance and reliability.

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, offering resistance to an extensive range of chemical media. Save for a few oxidizing agents, it entirely mitigates concerns about corrosion from soil and water quality.

 

Good Connection Security
Our pipes are primarily connected through heat fusion butt joints and electrofusion. This method seamlessly integrates the joints with the pipe material, ensuring the interface strength exceeds the strength of the pipe body itself.

 

High Flexibility
With a pipe elongation at break of ≥ 500%, our pipes demonstrate exceptional flexibility. They effectively accommodate uneven soil settlement and offer outstanding seismic performance.

 

Good Impact Resistance

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

 

Good Cracking Resistance

Boasting excellent rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively prevent 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.
• Smooth inner wall ensures strong circulation capability.
• Long service life, extending up to 50 years.
• High toughness with superior seismic resistance.
• Enhanced resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
