Key Feature of Stainless Steel Rotary Union

1 High-Quality Material​

Stainless Steel Construction: The pipe manufactured from premium-grade stainless steel, such as 304 or 316 stainless steel. These materials known for their outstanding corrosion resistance, which is essential in environments where the pipe may be exposed to moisture, chemicals, or other corrosive substances. For example, in chemical processing plants, where various corrosive liquids and gases are handled, the stainless steel construction ensures the long-term durability of the joint pipe.​
Strength and Durability: Stainless steel has high tensile strength, allowing the joint pipe to withstand high-pressure conditions. Whether in a hydraulic system that operates at high pressures or a steam pipeline where pressure fluctuations are common, the pipe can maintain its structural integrity over an extended period. This reduces the need for frequent replacements, saving both time and money in maintenance and operational costs.​

2 Flange Design​

Easy Installation: The flange connection design of the rotary joint pipe makes installation and 拆卸 relatively simple. Flanges are commonly used in piping systems because they provide a standardized and reliable way to connect different pipe sections. With appropriate tools and following standard installation procedures, the joint pipe can be quickly attached to the existing piping network, minimizing downtime during system setup or maintenance.​
Secure Connection: The flanges are designed to form a tight seal when bolted together. This ensures that there is no leakage of the fluid or gas passing through the pipe. In applications where the fluid being transported is expensive, toxic, or flammable, a secure connection is of utmost importance to prevent environmental pollution, safety hazards, and material waste.​

3 Rotary Functionality​

Smooth Rotation: The rotary joint allows for 360-degree smooth rotation between the connected piping sections. This is particularly useful in applications where one part of the piping system needs to move relative to another, such as in rotating machinery, conveyors, or swivel joints in industrial equipment. For instance, in a rotary dryer, the rotating drum needs to connected to a stationary steam supply pipe, and the rotary joint enables the continuous supply of steam while allowing the drum to rotate freely.​
Reduced Wear and Tear: The design of the rotary joint minimizes friction between the rotating parts. It may incorporate bearings or other lubricated components to ensure smooth movement and reduce wear. This not only extends the service life of the joint pipe but also contributes to the overall reliability of the piping system. Less wear and tear means fewer breakdowns and less frequent maintenance, improving the efficiency of the industrial process.​

4 Versatile Applications​

Wide Range of Industries: The stainless steel flange rotary joint pipe can used in various industries, including chemical, petroleum, power generation, food and beverage, and manufacturing. In the food and beverage industry, where hygiene is of utmost importance, the stainless steel material is easy to clean and maintain, meeting the strict sanitary standards. In the power generation sector, it can used in steam turbine systems to handle high-temperature and high-pressure steam.​
Diverse Fluid Compatibility: It is compatible with a wide range of fluids, including water, steam, oil, chemicals, and gases. The choice of stainless steel grade (such as 304 or 316) can customize based on the specific fluid and environmental conditions to ensure optimal performance and compatibility. For example, 316 stainless steel often used in applications involving seawater or highly corrosive chemicals due to its superior corrosion resistance compared to 304 stainless steel.

Quality Assurance​ of Stainless Steel Rotary Union

1 Manufacturing Processes​

The production of the stainless steel flange rotary joint pipe involves a series of strict manufacturing processes. These include cutting the stainless steel pipes to the required length, machining the flanges to the precise dimensions and surface finishes, assembling the rotary joint components, and performing various tests to ensure the quality and functionality of the product.​

2 Testing Procedures​

2.1 Pressure Testing

Each joint pipe subjected to pressure testing to ensure that it can withstand the specified maximum working pressure without any leakage. This done by filling the pipe with a suitable fluid (such as water or air) and applying pressure up to the test pressure, which is usually higher than the maximum working pressure, and observing for any signs of leakage or deformation.​

2.2 Leakage Testing

In addition to pressure testing, leakage testing carried out using methods such as bubble testing (for air-filled pipes) or using sensitive leak detection instruments. This ensures that the seal between the flanges and the rotary joint is tight and that there is no leakage of the fluid or gas passing through the pipe.​

2.3 Rotation Testing

The rotary functionality of the joint pipe tested to ensure smooth rotation at the specified speed and without any abnormal noise or vibration. This is important to ensure that the joint pipe can operate efficiently in the intended applications.​

3 Quality Certifications​
