Related Introduction

Mechanical seals and static seals have been used by human society for a long time, such as the sealing of wine barrels in food manufacturing. However, it was not until the industrial revolution (the end of the 18th century) that the use of steam required steam engines and boiler pressure vessels to achieve rapid development. The development of chemical and petrochemical industries further accelerated the technological progress of static sealing. The current static sealing technology has been able to solve most of the static sealing problems. The pressure ranges from vacuum 300MPa, the temperature ranges from -180 to 1,201, and the diameter to 12m. However, because the influencing factors of static sealing technology are very complicated, theoretical research is difficult, and the experimental cost is high, the important performance index of static sealing, leakage rate, still cannot be quantitatively determined, and the reliability still cannot meet engineering requirements.

We provide customers with quality products and services that are most suitable for the market, and are committed to becoming one of the high-quality suppliers in the global UR Rod Seal field. We continuously improve the quality of our products, always surpass the needs of customers and meet the changes of the market. Win-win is the inevitable trend of modern market economy and the basic value orientation of our innovative future.
