The flat welding flange not only saves space and weight but also ensures that joints do not leak, boasting excellent sealing performance. By reducing the sealing diameter, the size of the compact flange is minimized, thereby decreasing the cross-sectional area of the sealing surface.

2. Replacing flange gaskets with sealing rings ensures a proper match between the sealing surface and the mating surface. As a result, the sealing surface can be compressed with minimal pressure, and with the reduction in required pressure, the size and quantity of bolts are also decreased. To address this, a new product with a small volume and light weight has been designed.

Therefore, a flat welding flange is a relatively superior type of flange product, reducing both its weight and space, and playing a crucial role in industrial applications.
