What is the difference between a round flange and a square flange?
2025-03-10
In our daily work as flange manufacturers, round flanges and square flanges are two common product types. They each have unique designs, manufacturing processes and application scenarios. The following is our company's analysis and comparison of these two flanges.
1. Design and manufacturing process
(1) Round flangeThe round flange is simple and efficient in design. It is usually composed of a round metal plate with a pipe hole in the center and bolt holes evenly distributed around it. We use precision stamping, forging or welding processes to ensure its dimensional accuracy and strength. Due to the symmetry of the circular structure, the round flange can evenly disperse the pressure when it is stressed, thereby reducing stress concentration and improving the reliability of the connection.
(2) Square flange
The square flange has a square shape and is usually used for specific industrial equipment connections. When manufacturing square flanges, we need to customize the design according to the specific needs of the customer. During the processing process, the bolt hole position and size of the square flange need to be accurately calculated to ensure stability and sealing during installation.
2. Application scenarios
(1) Round flangeCircular flanges are widely used in various fluid transmission systems, such as water pipes, gas pipes, oil pipelines, etc. Its circular structure can effectively disperse pressure and ensure the stability and sealing of the connection. In addition, the standardized design of the circular flange makes it more convenient during installation and maintenance, and can be quickly replaced and repaired.
(2) Square flange
Square flanges are mainly used for the connection of some special equipment, such as hydraulic systems, ventilation ducts, wine brewing equipment, etc. In these application scenarios, square flanges can better adapt to the structural characteristics of the equipment and provide more stable support and connection.
3. Performance and advantages
(1) Round flangeThe biggest advantage of the round flange is that it is evenly stressed and can withstand higher pressure and temperature. The symmetry of the round flange also makes it easier to align and fix, reducing installation time and cost.
(2) Square flange
The advantage of the square flange is its compact structure and stability. In some equipment that needs to be closely arranged, the square flange can make better use of space and improve the overall layout efficiency of the equipment.
Conclusion
As a flange manufacturer, Qingdao Micro Precision Machinery Co., Ltd. is well aware that round flanges and square flanges each have their own unique characteristics and advantages. In actual production, we will carefully design and manufacture each hydraulic product according to customer needs and application scenarios to ensure that its quality and performance can meet customer expectations.
