The double wall corrugated pipe equipment has undergone three generations of updates, each with its own unique technical characteristics.

The first generation of double wall corrugated pipe technology was manufactured in the form of air cooling. The two layers of casing were independently manufactured and then combined with heat treatment to form the first generation of double wall corrugated pipe equipment through air cooling. The first generation corrugated pipe equipment has a simple manufacturing process, long production time, low hardness, poor resistance to impact, easy deformation, and short service life. The quality is guaranteed in the short term, and regular inspection and replacement are required for quality problems in long-term use.

The second generation double wall corrugated pipes are processed using a water cooling method for heat treatment. The first layer of casing is processed and combined with the second layer of casing through a heat treatment process, and then subjected to water cooling treatment before finally forming. The technology of the second-generation double wall corrugated pipe equipment has been improved, the production time has been greatly reduced, and the manufacturing cost has remained almost unchanged. However, the quality of the equipment produced by different processes has been greatly improved, the hardness of the product has been greatly increased, the toughness has also increased, and the service life has been significantly extended. It is suitable for short-term and long-term use, with guaranteed quality, low replacement frequency, and low damage rate.

The third-generation double wall corrugated pipe has different heat treatment processes from the previous two generations. The third-generation double wall corrugated pipe equipment adopts an air cooling and water cooling method for processing. In the initial stage, it is cooled in the air for a period of time to meet certain requirements for product performance. During water cooling, the hardness and toughness are improved, and various properties are also synchronously improved. The first generation of double walled corrugated pipe equipment had many prominent problems and poor quality, while the second generation also had some well-known defects. In order to improve the shortcomings of the previous two generations, the third generation of double walled corrugated pipe equipment comprehensively analyzed and studied the previous shortcomings, and developed a heat treatment process processing method that combines the two. This has led to unprecedented levels of physical properties, chemical properties, aerodynamics, weather resistance, corrosion resistance, and other aspects of the double walled corrugated pipe equipment, ensuring complete quality assurance.

The double wall corrugated pipe equipment has gone through the development of three generations of products, and currently has a solid market share, winning the love of the masses, using it with ease and peace of mind. I believe that in the context of social progress and increasing demand for products, double wall corrugated pipe equipment will develop more outstanding products. Keep it invincible.
