The procedure for installing a forged flange is as follows: Preparations: Before installing the forged flange, check the quality of the forged flange and related hydraulic components, and prepare required materials and tools, such as bolts, gaskets, and sealants. Cleaning work: First, clean the surface of the flange and pipe connection to ensure that it is clean and dust-free. You can use a cleaner or a tool such as a scraper to remove dirt and grease from the surface. Arrange flanges: Place the flanges flat on the work table, and determine the position and direction of the flanges according to the size and shape of the connecting port. Make sure that the connection holes of the flange match the corresponding connection holes of the pipe. Install gaskets and sealants: Apply a layer of sealants to the surface of the flange connection holes to increase sealing performance. Then, place the spacer over the connecting hole, making sure that the spacer is perfectly aligned with the connecting hole. Connect the pipe: Align the pipe with the connecting hole of the flange and hold it with your hand to keep it in position. Then, insert the bolts into the connecting holes one by one and tighten them gradually with a wrench or wrench socket. Evenly tighten the bolt: In the process of connecting the bolt, pay attention to maintain the uniform strength of the bolt to avoid deformation or damage to the flange due to local too tight. After bolts are tightened, check whether the bolts are even and adjust them if necessary. Check the sealing performance: After the installation is complete, touch the flange joint to ensure that the bolts are tight and not loose, and check the sealing performance of the flange and whether the connection is firm through visual and pressure tests. Please note that when installing forged flanges, appropriate sealing materials, bolt specifications and torque values should be selected according to the actual situation to ensure a safe and reliable connection. If necessary, you can refer to the installation manual of the hydraulic system equipment or consult a professional for guidance.
