DN200 swivel unions

DN200 high-speed rotary joint is an industrial fluid sealing device with a nominal diameter of 200 millimeters. Its core function is to continuously and leak free transport of fixed pipeline media (such as thermal oil, water, air, etc.) to rotating equipment under high-speed conditions. ‌‌

Product Features:
Welding, flanges, threads; The internal structure of DN type rotary joint is directly supported by high-precision bearings, which can rotate back and forth or at low speed, with high wear resistance, flexible rotation, and strong support ability. The sealing element adopts imported sealing element, which is used for the movable joint of guiding fluid medium between steel pipelines. The internal part is directly supported by ball bearings, with good rotation performance, strong support force, and good wear resistance. The reciprocating swing rotary joint has a long service life and is made of special rubber material, which is not only reliable in sealing but also able to withstand high temperatures. It is widely used in industrial fields such as metallurgy, petrochemicals, ships, and papermaking.

A rotary joint is a device used to connect fixed pipelines and rotating equipment, allowing fluid to transfer between the rotating and fixed parts without leakage. In steel plant converters, rotary joints are particularly important because they can be used to cool steel ladles, ensuring the safety and efficiency of the production process.
The following is an introduction to the DN200 rotary joint with dual channel one in one out cooling water dedicated rotary joint:
