Flange is divided into flat welding flange and butt welding flange. Flat welding flange is the most common, among which flat plate flange is the most common. The flat welding flange with high sales volume of Shanxi Haokun flanges Group Co., Ltd. is also a flat flange.
Features of flat welding flange:
The flat welding flange not only saves space and reduces weight, but also ensures that the joint will not leak and has good sealing performance. The reduction in the size of the compact flange is due to the reduction in the diameter of the seal, which flat welding flangewill reduce the section of the sealing surface. Second, make sure that the sealing ring is matched with the sealing face of the flat welding flange. In this way, only a small pressure is required to compress the sealing surface. With the decrease of the required pressure, the size and quantity of flat welding flange bolts can be reduced accordingly. Therefore, a new product with small volume and light weight (70% ~ 80% less than the weight of traditional flange) is finally designed. Therefore, flat welding flange is a relatively high-quality flange product, which reduces the quality and space and plays an important role in flat welding flange industrial use. However, the main design disadvantage of flat welding flange is that it can not guarantee no leakage. This is the deficiency of flat welding flange’s design: the connection is dynamic, and such as thermal expansion and fluctuating periodic load will cause the movement between flange faces and affect the function of flat welding flange, so as to damage the integrity of flange and eventually lead to leakage. No product can be free of defects, but try to control the deficiency of the product to the minimum. Therefore, the company tries to improve the performance
