Product Description
Polyethylene gas pipes have become the top choice for gas distribution systems. Their lightweight nature, resistance to corrosion, availability in convenient coil lengths, and ease of installation through heat fusion or mechanical fittings make them unparalleled in performance. Since their introduction in the 1960s, PE pipes have demonstrated exceptional reliability and durability, solidifying their status as the industry standard.
Shandong Donghong Pipe Industry Co., Ltd. proudly manufactures specialized PE pipes for mining applications using the advanced PE100-RC material, an enhanced version of PE100.This upgraded material boasts significant improvements, including high Minimum Required Strength (MRS), outstanding Slow Crack Growth (SCG), superior Rapid Crack Propagation (RCP) resistance, and exceptional melt strength LS. Ideal for gas transfer, these pipes offer anti-corrosion properties, remarkable flexibility, and minimal medium loss.

Anti-corrosion
Polyethylene (PE) is an exceptionally robust and inert material, offering resistance to a vast array of chemical media. Apart from a few oxidizing agents, it stands up effortlessly to both soil and water without succumbing to corrosive effects.
Secure Connection
Pipes are predominantly joined through heat fusion butt joints and electrofusion. This process seamlessly integrates the joints and pipe materials, ensuring that the interface strength surpasses the pipe body's own strength.
High Flexibility
Exhibiting a pipe elongation at break of ≥ 500%, our pipes boast exceptional flexibility. They adeptly manage uneven soil settlement and exhibit superior seismic performance.
Excellent Impact Resistance
Designed to perform in low-temperature environments (-20ºC to -40ºC), these pipes resist external impacts and are not prone to cracking or other damages.
Exceptional Cracking Resistance
Our pipes demonstrate outstanding resistance to rapid crack propagation (RCP) and slow crack growth (SCG). This effectively mitigates the risk of cracking and crack spreading, even in low-temperature conditions or if installation damage occurs.
Low Friction Coefficient
With a smooth inner wall and non-adhesive properties, our pipes maintain optimal conveying capacity and minimize pressure loss within the pipeline.
Product Description:
- Low density, lightweight, and easy to handle and install.
- Corrosion resistance to various chemical mediums.
- Smooth inner wall, ensuring strong circulation capacity.
- Long service life: up to 50 years.
- High toughness and excellent seismic resistance.
- Enhanced resistance to slow crack growth (SCG) and rapid crack propagation (RCP).
