Product Description

Polyethylene gas pipes are the ultimate solution for gas distribution systems. These pipes stand out for their exceptional lightweight construction, non-corrosive qualities, and the convenience of coil lengths. Installation is remarkably simple, facilitated through either heat fusion or mechanical fittings. These unique characteristics have cemented PE pipes as dependable and long-lasting options since their debut in the 1960s.

Shandong Donghong Pipe Industry Co., Ltd. expertly crafts specialized PE pipes designed specifically for the rigorous demands of mining applications. By employing the state-of-the-art PE100-RC material, an advanced variant of PE100, these pipes deliver unmatched performance.The advanced PE100-RC material offers substantial enhancements in critical attributes such as high Minimum Required Strength (MRS), outstanding resistance to Slow Crack Growth (SCG), exceptional Rapid Crack Propagation (RCP) resistance, and superior melt strength LS. For gas transfer applications, these pipes provide extraordinary anti-corrosion properties, high flexibility, and minimal medium loss, setting a new benchmark in the industry.

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 a vast range of chemical media. Except for a few oxidizing agents, it effectively eliminates concerns about corrosion from both soil and water quality.

 

Good Connection Security
Our pipes are primarily connected using heat fusion butt joints and electrofusion. This technique ensures seamless integration of the joints with the pipe material, making the interface strength surpass the strength of the pipe body itself.

 

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

 

Good Impact Resistance

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

 

Good Cracking Resistance

Featuring 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 minimizing pressure loss within the pipeline.
