In pipeline engineering, flanged pipe expander is a common accessory, which is mainly used to connect pipes and equipment, and allow them to expand and contract freely under conditions such as temperature changes, vibration, and mechanical displacement, thereby reducing stress and strain, and extending the service life of equipment.
The sleeve type telescopic device consists of two sleeves and a sealing ring, which are bolted together. This kind of telescopic device has a simple structure, easy installation, and is suitable for small pipe diameters. The bellows expander consists of a bellows and a fixed bracket that absorbs the displacement of the pipe through the elastic deformation of the bellows. This type of retractor is suitable for situations where the pipe diameter is large and the displacement is small.
When installing the flanged pipe expander, it should be ensured that its connection with the pipe and equipment is firm and reliable to avoid loosening or leakage. The appropriate type and specification of the expander should be selected according to the displacement amount and displacement direction of the pipeline. In the process of use, the sealing performance and bolt tightening of the flange pipe expander should be checked regularly, and the abnormalities should be dealt with in time. For corrosive media, wearing parts such as seals and bolts should be replaced regularly.
