The developed flat flange is a kind of flange product with good process characteristics and performance. Cast steel flange can show good use value and function in use, and overcome the shortcomings of traditional butt welding flange. The compact flange has many advantages: the standard flange not only saves space and weight, but also ensures that the joint will not leak. The size of the butt welding flange will be reduced in use. The reason why the size of the butt welding flange is reduced is that the diameter of the seal is reduced, which will reduce the section of the sealing surface. Secondly, the gasket of the butt welding flange has been replaced by the sealing ring to ensure the matching of the sealing face. As the required pressure decreases, the size and number of bolts can be reduced accordingly. *Finally, a new product with small volume and light weight (70% – 80% less than the weight of the traditional counter flange) is designed. The plate flange has good use value and function in use. Use it according to the corresponding way and method to avoid certain quality and function problems in use.

The flat flange connection is easy to use and can bear large pressure. Flange connection is widely used in industrial pipeline. In the home, the diameter of the pipe is small, and it is low pressure, and the flange connection is invisible. If in a boiler room or production site, there are flange connected pipes and equipment everywhere. The rolling flange is made by cutting the middle plate into battens, then rolling it into circular welded joints, and then flattening it. There are two kinds of coiling: cold coiling and hot coiling. After machining into a circle, the water line, bolt hole, stop and other processes shall be processed. This is generally a large flange, a molding can be done 7 meters. Plate type flat welding flange is the most common, and the connection mode is welding. If the production process of segmented production is used, the specification of 12m-15m or larger can be achieved. This kind of flange has good quality assurance. Because the raw material is medium plate with good density. The welding process at the joint of the rolling flange is the most important, and X-ray or ultrasonic film detection shall be carried out. If the joint is finished, there will be no problem with the material of the whole flange.
