Product Description

Polyethylene gas pipes are the ultimate choice for sophisticated gas distribution systems. Renowned for their lightweight construction, non-corrosive nature, and the convenience of coil lengths, these pipes make installation a seamless process, accomplished either through heat fusion or mechanical fittings. Introduced in the 1960s, PE pipes have consistently proven to be reliable and durable solutions, earning their place as a trusted option in the industry.

At Shandong Donghong Pipe Industry Co., Ltd., we specialize in the production of cutting-edge PE pipes engineered to meet the rigorous demands of mining applications. Our pipes are constructed from the advanced PE100-RC material, an enhanced version of standard PE100, which guarantees unparalleled performance and reliability across various challenging conditions.The innovative PE100-RC material features substantial improvements in several vital properties. It offers exceptional Minimum Required Strength (MRS), superior resistance to Slow *** Growth (SCG), impressive Rapid *** Propagation (RCP) resistance, and outstanding melt strength LS. In gas transfer applications, these pipes excel with their exceptional anti-corrosion properties, superior flexibility, and minimal medium loss, making them the premier 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 resistance to rapid *** propagation (RCP) and slow *** growth (SCG), our pipes effectively prevent cracking 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.
• Corrosion resistance against a variety of chemical media.
• A smooth inner wall ensures robust circulation capability.
• Long service life, extending up to an impressive 50 years.
