Rotary joint has been widely used in industrial production, the flange convergence and the sealing areas, mainly for transporting water, oil, steam and other media, its field of application covering almost metallurgy, petroleum, pharmaceutical, power generation, and all other manufacturing industries. Here the main view of the development process of the rotary joint.

Rotary joint appeared in 1933, before the packing gland, etc. mainly as a means of water or steam sealing, medium sealing effect not only poor, but also a media leak. Until 1933 the first rotary joint was born, to be effective to improve the situation. The key of the first-generation rotary joint seal that the seal ring and spring-loaded mechanical seal design, the medium to circulate in a completely sealed environment, effectively reducing the damage rate of the seal device.

After World War II, with the rotary joints become the preferred way to seal each medium flows, a broader scope of innovation and joint design, as well as its resistance and flexibility greatly increased, better able to meet the different needs of the various sectors of the rotary joint. In 50's, the key development is the application of the siphon technology and pressure requirements, temperature adaptability, size design, material selection and so on are innovation, continuous improvement and innovation rotary union for the development of the industry has made great contributions.

Looking back on the development process of the rotary joint, can be found there is a market demand have innovation, innovation is the development. For rotary joint production enterprises, how to make their products always walk in the forefront of the industry to maintain their own unique advantages is the top priority. The manufacturing sector is also inseparable from the scientific and technological innovation, no doubt, only to better meet market demand, strengthen scientific and technological innovation, is the decisive factor in the development of enterprises.
