PE100 gas pipe

PE100 gas pipe

characteristic: Society is accelerating its development, and people's living conditions are constantly improving. The use of household gas stoves and kitchens is gradually changing to natural gas pipelines that deliver gas into the household kitchen. Plastic materials have a new field in pipeline transportation, which has completely changed the concept of pipeline engineering and brought tremendous technological progress to the pipeline field. More importantly, it has brought enormous economic and social benefits to human society. In this revolution, polyethylene (PE) pipes stand out due to their more stable chemical properties and superior physical and mechanical properties.
In the mid-1950s, the world began using polyethylene pipelines to transport gas. A large number of experiments and engineering practices have confirmed that polyethylene pipes are the most ideal gas pipelines, with good safety performance and higher reliability than steel pipes. They are widely used in many fields to resist natural disasters such as earthquakes and ground subsidence. The excellent performance of polyethylene gas pipelines is manifested in:
1. Long service life - can be safely used for at least 50 years under rated temperature and pressure conditions.
2. Corrosion resistance - Polyethylene is chemically inert, and natural substances in soil do not cause any corrosion. It is suitable for various soil environments and requires minimal maintenance during operation.
3. Good flexibility and impact resistance - The inherent elasticity and flexibility of polyethylene make the pipe bendable, capable of absorbing impact pressure, water hammer, vibration, and pressure generated by soil movement. Therefore, it can be laid in a snake shape, easily bypassing obstacles, and has been proven to resist natural disasters such as earthquakes and ground subsidence.
4. Good safety - Polyethylene pipes have high air tightness, firm connection joints, extremely low gas permeability and leakage rate, and reliable safety inspections.
5. Good anti-aging performance - the pipeline is black and yellow, which can effectively resist the ultraviolet rays in the sun and enhance the anti-aging performance of the pipeline.
6. Simple construction - polyethylene pipes are lightweight and easy to transport; The pipeline system adopts hot melt, electric melt, steel plastic transition and flange connection. The construction equipment has a small volume, light weight, simple operation, and is particularly suitable for field operations. It is safe, reliable, convenient and fast.
7. Low comprehensive engineering cost - Compared with traditional steel pipelines, polyethylene pipelines greatly save installation labor costs and equipment material investment. It also reduces operation and maintenance costs and extends service life, so it has a lower comprehensive engineering cost. According to calculations, it is only 2/3 of steel pipes within a certain diameter range.

After decades of development, the production, processing, construction, and use technology of gas polyethylene pipelines has been very advanced and has been widely promoted and applied in economically developed Western countries. The United States is the world's largest producer of plastic pipes, with 95% of gas pipelines using polyethylene pipes. The penetration rate of polyethylene gas pipelines in countries such as Europe, Japan, and South Korea is also as high as 80% -90%. In the announcement on chemical building materials technology and products issued by the Ministry of Construction on July 4, 2001, it has become a consensus that polyethylene pipes have excellent performance and outstanding economic benefits.
