Description

Technical Field

[0001] The utility model relates to the technical field of flange installation, in particular to an auxiliary device for flange installation. Background Art

[0002] Flange installation is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange gaskets between the two flange plates, and fasten them together with bolts to complete the installation.

[0003] A flange auxiliary installation device is disclosed in the Chinese utility model patent application disclosure CN217899156U. Although the device moves the second flange plate, fits the blade of the second flange plate with the other end face of the sealing gasket, connects the two flange plates by bolts and nuts, and finally separates the two positioning blocks, and respectively takes out the two positioning support parts from the gap to complete the installation of the flange, the operation is more convenient, and the installation efficiency can be improved, but the existing device does not solve the problem that the pipeline surface cannot be directly welded to the flange after rusting. During the welding process of the flange and the pipeline, the residual rust debris on the surface is easy to cause the welding strength to decrease and the welding part is prone to cracks, thereby affecting the welding quality. After the pipeline flange is installed, the two pipeline ports cannot be aligned, resulting in the inability to connect the two flanges by bolts. The old flange is not convenient to be disassembled from the pipeline and the new threaded flange is not convenient to be installed on the pipeline. Therefore, we propose a new device to solve the above problems. Utility Model Content
