Now, in line with the evolving needs of our daily lives, PE gas pipes are no longer confined to urban areas—most rural regions across provinces and cities have also begun adopting PE gas piping systems. First, when we see the term “PE gas pipe,” we naturally assume it’s used for transporting natural gas. But how exactly does its performance differ from that of ordinary PE water pipes? Let’s take a closer look and find out.

Product Features: Natural gas PE pipes must be able to withstand a certain level of pressure; therefore, PE resins with high molecular weights and excellent mechanical properties are typically selected. A high-quality pipeline should not only offer good economic performance but also exhibit a series of advantages, including stable and reliable joints, as well as materials that are impact-resistant, crack-resistant, age-resistant, and corrosion-resistant. Compared with traditional piping materials, polyethylene pipes containing 2-2.5% uniformly distributed carbon black have a specified service life of 50 years and must be buried when used as gas pipelines. These pipes are significantly affected by temperature: if the ambient temperature exceeds their operating range, the pipes may experience premature aging, reduced strength, and eventual failure under the internal gas pressure, leading to natural gas leaks that pose serious hazards.

Connection Methods: For PE gas pipes, there are two primary connection methods: Electrofusion Welding—This method uses a dedicated electrofusion welding machine to join straight pipes to straight pipes or straight pipes to fittings. It is commonly used for pipes with diameters of 160 mm or less. Fusion Butt Welding—This method employs a specialized butt-welding machine to join pipes together and is typically used for pipes with diameters of 160 mm or greater. Steel-Plastic Connections—These can be made using flanges, threaded connections, or other similar methods.

Appearance color: The one we commonly see PE gas pipe The color is black with yellow vertical stripes on top. PE water supply pipe It’s the black pipe with blue stripes—why are different colors used to mark them? Clearly, it’s to distinguish between the two. But some might argue that apart from the color, everything else is the same. Well, you’d be dead wrong! Let’s continue reading: PE gas pipes, being designed for transporting gases, can pose a serious risk of combustion and explosion due to gas friction. Therefore... PE gas pipe The materials used include an antistatic additive. Relatively speaking, the raw material cost of PE gas pipes is significantly higher than that of PE water pipes.
