The development direction of PVC pipe production line

The PVC pipe production line has a history of nearly 70 years. Due to the characteristics of high strength and low cost, PVC pipes have been widely used worldwide. However, for a period of time, the performance level of PVC pipe systems has not improved significantly, and the growth rate has slowed down in some countries and application fields.

The domestic PVC piping system has formed a huge scale, with an annual output of more than one million tons, but it still stays within the scope of traditional PVC-U. Many companies do not know much about the international innovation trend and progress of PVC piping technology, and the slow technological progress restricts Its further promotion and application.

PVC pipe

In recent years, domestic and foreign continuously explore to improve the performance level of PVC piping system, expand the scope of application of PVC piping system, and have achieved remarkable results. Main direction:

Improve the toughness through modification, develop a variety of modified PVC pipes with good impact and crack resistance while maintaining high strength, usually called PVC-M, PVC-A or PVC-HI.

In the process of pipe processing, through biaxial stretching, the molecular orientation can be greatly improved while increasing the toughness. It is generally called PVC-O or PVC.

Expand the scope of application, such as: through improvement and modification, the PVC pipe can be bent, bendable, and even welded. Used for trenchless repair of the lining of old pipes.

The changes and development of the international situation in recent years have provided unprecedented historical opportunities for the development of my country's PVC piping system. PVC piping systems have been severely affected by the skyrocketing oil prices in many application fields and in the PVC piping system competition market. PVC can use coal as the raw material because it is kept at a low price to obtain raw materials, thereby increasing its competitiveness. Facing new market opportunities, if we can accelerate innovation and development and keep up with the international development of PVC piping system technology, we can create a new situation. We recommend Zhangjiagang Wellman Machinery Equipment Co., Ltd.: PE pipe production line, pp-r pipe production line, and three-layer PE co-extrusion pipe production line.

After December, as the main PVC contract was transferred to the 1003 contract, the enthusiasm for market participation gradually increased. Throughout the day on the 8th, the main PVC contract 1003 increased by more than 40,000 lots, and the futures price strongly broke through the previous round of 7,500 yuan/ton. The increase on the day was more than 4%, laying the foundation for the market outlook. In the next few trading days, the futures price basically fluctuated in the range of 7,500-7,700 yuan/ton, and the transaction also remained high. This situation reminds investors of the trend of the domestic PVC futures market at the end of July and early August this year. At that time, due to the exchange's storage capacity restrictions, the longs used a large amount of funds. However, as the exchange's storage capacity expanded, the 909 contract was successfully delivered, and the PVC futures price finally changed from The high level fell sharply. Therefore, will the future price of PVC futures repeat the same mistakes and fall sharply from the high level? The author believes that the possibility is unlikely, and the domestic PVC still has further upward momentum in the later period.
