Product Description

Polyethylene gas pipes stand as the pinnacle of choice for advanced gas distribution systems. Celebrated for their lightweight construction, corrosion-resistant nature, and the ease of coil lengths, these pipes revolutionize installation, which can be effortlessly accomplished through heat fusion or mechanical fittings. Since their introduction in the 1960s, PE pipes have consistently demonstrated their reliability and durability, cementing their status as a trusted industry staple.

At Shandong Donghong Pipe Industry Co., Ltd., we excel in manufacturing state-of-the-art PE pipes designed to meet the stringent demands of mining applications. Our pipes are crafted from the innovative PE100-RC material, an enhanced variant of standard PE100, ensuring unmatched performance and reliability under the most challenging conditions.The groundbreaking PE100-RC material boasts significant advancements in several critical properties. It offers remarkable 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 shine with their excellent anti-corrosion attributes, exceptional flexibility, and minimal medium loss, making them the top choice for long-term reliability and operational 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 *** propagation (RCP) and slow *** growth (SCG) resistance, 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 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.
