Description

Technical Field

[0001] The invention relates to a support and hanger in the field of pipelines, and in particular to an installation method of a TXZDPI type support and hanger. Background Art

[0002] During the shipbuilding process, the piping system is an important component of the ship. Most of the pipes installed on the ship are installed on the ship through supports and hangers. The vibration and noise generated by the pumps, accessories and other devices in the piping system are transmitted along the pipe wall and the fluid medium in the pipe, and then transmitted to the hull through the pipe supports and hangers. After a long period of strong vibration, the pipeline will cause fatigue damage to the pipeline and pipe fittings, resulting in pipeline rupture, economic losses and major safety accidents. The vibration of the pipeline will also consume the energy of the system, causing unnecessary energy loss and reducing mechanical efficiency. In order to reduce the vibration transmission of the pump in the ship's engine room, elastic supports and hangers should be used in the piping system to support the weight of the pipeline and its internal liquid to reduce vibration transmission.

[0003] At present, the research and development of supports and hangers in my country is relatively fast, and a series of TXZDPI supports and hangers with good vibration reduction effect and excellent impact resistance have been developed.

[0004] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application: TXZDPI type supports and hangers are mainly used for the support, fixation and vibration isolation of normal temperature pipelines, and can be used in the whole process of system operation. The traditional installation method is to select TXZDC type supports and hangers that meet the technical requirements and install them directly on the system pipelines. There is a lack of pipeline pre-installation process, which can easily cause damage to equipment, accessories, pipelines and supports and hangers during the installation process. Therefore, correctly installing supports and hangers to fix pipelines and reduce the transmission of pipeline vibration has great theoretical value and practical engineering significance for the safety of the hull. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the embodiment of the present application provides a method for installing TXZDPI type supports and hangers to avoid damage to equipment, accessories, pipelines and supports and hangers and ensure that TXZDPI type supports and hangers can fully exert their vibration reduction effects. The method first sets a temporary rigid support for the pipeline, and then completes the connection between the pipe section and the pipeline accessories and the vibration reduction pipe under the rigid support state, and finally realizes the installation and adjustment of the TXZDPI type supports and hangers; installing the TXZDPI type supports and hangers under the rigid support state can effectively avoid deformation and installation tolerance of the TXZDPI type supports and hangers, improve the qualified rate of the XZDPI type supports and hangers, ensure the service life of the TXZDPI type supports and hangers, so that the TXZDPI type supports and hangers can fully exert their vibration reduction effects and solve the technical problems of the installation of the TXZDPI type supports and hangers.

[0006] The solution adopted by the embodiment of the present application to solve the technical problem is: A method for installing a TXZDPI type support and hanger, firstly, temporarily setting a rigid support for the pipeline, secondly, completing the connection between the pipe section and the pipeline accessories and the vibration reduction pipe under the rigid support state, and finally, installing and adjusting the TXZDPI type support and hanger; comprising the following steps: (1) Select TXZDPI type supports and hangers that meet the rated load of the piping system, and whose static deformation does not exceed 2mm±0.6mm; (2) Check whether there are any damage or cracks on the surface of the elastic element of the TXZDPI type support and hanger. The surface of the metal parts should be flat and smooth, without burrs, cracks or defects that affect its performance and safety, and meet the installation and use requirements; (3) Preload the TXZDPI type support and hanger with rated load for 48 hours to eliminate creep; (4) Connect the equipment, pipelines, and accessories according to the pipeline system installation diagram, and use temporary rigid support 1 to fix the pipeline system to complete the pipeline preinstallation; (5) Buckle the upper and lower hinges of the TXZDPI type support and hanger to the pipeline, tighten the fastening bolts to complete the connection with the pipeline. The installation coordinates of the TXZDPI type support and hanger are based on the center line of the pipe; (6) After the pipeline is positioned and pre-installed, measure the installation surface and structure height of the TXZDPI type support and hanger to confirm the length of the support base; (7) The length of the support base should be adjusted. The influence of welding deformation should be considered when adjusting the length of the support base. (8) Fix the support base by welding. Remove the TXZDPI type support bracket before welding the support base and keep it away from the welding part to prevent the ozone generated by welding from affecting the life of the TXZDPI type support bracket; (9) Measure the thickness of the required pad, process the pad, and determine the mounting holes of the pad and the support base panel; (10) Install and tighten the TXZDPI type support and hanger according to the position of the support base and the pipeline. The connection should ensure that the bottom surface of the TXZDPI type support and hanger is parallel to the pipeline axis, and the axis of the TXZDPI type support and hanger clamp is parallel to the pipeline axis; (11) Remove the temporary rigid support of the pipeline; (12) Check the deformation of the TXZDPI type supports and hangers of the pipeline section. The deformation of the supports and hangers after installation should be within the rated range; (13) Adjust the TXZDPI type support bracket to meet the installation process requirements.

[0007] Positive effects: The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages: Since the embodiment of the present application adopts the technical means of first setting a temporary rigid support frame for the pipeline, and then completing the connection between the pipe section and the pipeline accessories and the vibration-damping pipe under the rigid support state, and finally realizing the installation and adjustment of the TXZDPI type support and hanger, installing the TXZDPI type support and hanger under the rigid support state can effectively avoid the installation deformation and installation tolerance of the TXZDPI type support and hanger, improve the installation qualification rate of the XZDPI type support and hanger, ensure the service life of the TXZDPI type support and hanger, and enable the TXZDPI type support and hanger to give full play to its vibration reduction effect. Setting a temporary rigid support frame when installing the pipeline can also effectively reduce the stress and deformation of the pipeline for equipment and accessories with larger mass, avoid damage to the equipment and accessories, and effectively solve the technical problems of the installation of the TXZDPI type support and hanger in the prior art, thereby achieving the technical effect of improving the installation qualification rate and service life of the TXZDPI type support and hanger.
