Product Description

Polyethylene gas pipes are the ultimate choice for modern gas distribution systems. These distinguished pipes are renowned for their lightweight nature, non-corrosive properties, and availability in convenient coil lengths. Installation is effortlessly accomplished through either heat fusion or mechanical fittings. Owing to these exceptional qualities, PE pipes have earned their reputation as reliable and enduring solutions since their inception in the 1960s.

At Shandong Donghong Pipe Industry Co., Ltd., we excel in the production of cutting-edge PE pipes, meticulously engineered for the rigorous demands of mining applications. Our pipes are manufactured from the superior PE100-RC material, an advanced version of standard PE100, guaranteeing unparalleled performance and dependability.The state-of-the-art PE100-RC material integrates significant advancements in several critical attributes. It features high Minimum Required Strength (MRS), exceptional resistance to Slow *** Growth (SCG), remarkable Rapid *** Propagation (RCP) resistance, and superior melt strength LS. For gas transfer applications, these pipes deliver unrivaled anti-corrosion properties, exceptional flexibility, and minimal medium loss, making them the quintessential choice for long-term reliability and efficiency.

Connection Method

 

1. Elctric fusion connection.

2. Butt fusion Connection.

3. Flange Buckle Connection

 

Product Features

 

**Anti-corrosion**

Polyethylene (PE) is renowned for its exceptional inertness, demonstrating formidable resistance to a wide spectrum of chemical substances. Except for a select few oxidizing agents, it completely eliminates concerns about corrosive effects from soil and water quality.

 

**Good Connection Security**
Our pipes employ state-of-the-art heat fusion butt joints and electrofusion techniques for connections. This method seamlessly merges the joints with the pipe material, ensuring the interface strength surpasses that of the pipe itself.

 

**High Flexibility**
Boasting an impressive pipe elongation at break of ≥ 500%, our pipes offer remarkable flexibility. They adeptly manage uneven soil settlement and deliver exceptional seismic performance.

 

**Good Impact Resistance**

In low-temperature environments ranging from -20ºC to -40ºC, our pipes exhibit outstanding performance. They endure external impacts, effectively preventing cracks and other damages.

 

**Good Cracking Resistance**

With exceptional resistance to rapid *** propagation (RCP) and slow *** growth (SCG), our pipes effectively prevent cracking and *** propagation in cold regions 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 a broad range of chemical media.
• A smooth inner wall guarantees robust circulation capability.
• Long service life, extending up to an impressive 50 years.
• High toughness combined with superior seismic resistance.
• Enhanced resistance to slow *** growth (SCG) and rapid *** propagation (RCP).
