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.

At Shandong Donghong Pipe Industry Co., Ltd., we specialize in the manufacture of advanced PE pipes meticulously designed for demanding mining applications. Our pipes are crafted from the superior PE100-RC material, which is an enhanced version of the standard PE100, ensuring unmatched performance and reliability.The cutting-edge PE100-RC material incorporates significant advancements in several critical properties. It boasts high Minimum Required Strength (MRS), outstanding resistance to Slow Crack Growth (SCG), remarkable Rapid Crack Propagation (RCP) resistance, and superior melt strength LS. For gas transfer applications, these pipes offer unmatched anti-corrosion properties, superior flexibility, and minimal medium loss, making them the ideal 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 an exceptionally inert material, showcasing resistance to a vast array of chemical media. Save for a handful of oxidizing agents, it completely nullifies concerns about corrosive impacts from soil and water quality.

 

**Good Connection Security**
Our pipes utilize cutting-edge heat fusion butt joints and electrofusion for connections. This technique seamlessly integrates the joints with the pipe material, ensuring that the interface strength exceeds the strength of the pipe itself.

 

**High Flexibility**
With an impressive pipe elongation at break of ≥ 500%, our pipes demonstrate remarkable flexibility. They proficiently handle uneven soil settlement and offer outstanding seismic performance.

 

**Good Impact Resistance**

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

 

**Good Cracking Resistance**

Featuring exceptional rapid crack propagation (RCP) and slow crack growth (SCG) resistance, our pipes effectively prevent cracking and crack propagation in cold regions and during installation damages.

 

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

 

Product Advantages

**Product Description:**

• Low density, lightweight, and effortless to handle and install.
