How much do you know about the installation of stainless steel instrument pipes?
1. Stainless steel instrument tubes should not be installed in environments that are prone to vibration, mechanical damage, strong magnetic field interference, humidity, high temperature, severe temperature changes, and corrosive gases.
2. The height of the instrument center from the ground is 1.2~1.5m.
3. If the instrument is installed locally, it should be installed at a position where it is convenient to observe the indicated value of the instrument when operating the valve manually.
4. Before installation, the appearance of the instrument tube should be complete, and the accessories should be complete, and the model, specification and material should be checked according to the regulations.
5. During installation, it is forbidden to knock or vibrate the equipment, and ensure that the equipment after installation is firm and flat.
6. After passing the degreasing test, the equipment for degreasing according to the design rules must be installed.
7. The instrument tubes installed directly on the process pipeline should be installed before the pressure test after the process pipeline is purged. If it must be installed together with the process pipeline, the instrument should be removed when the process pipeline is purged.
8. The direction of the arrow on the instrument casing should be consistent with the flow direction of the measured medium.
9. When the instrument is connected to the process pipeline, the axis of the flange on the instrument should be consistent with the axis of the process pipeline, and it should be evenly stressed when fixed.
10. For instruments directly installed on process equipment or pipelines, pressure tests should be carried out together with the process system after installation.
11. The inlet of the junction box on the instrument tube and electrical equipment cannot face upwards to prevent oil, water and dust from entering the box. If unavoidable, sealing measures should be taken.
12. The words and terminal numbers on the instrument tubes and electrical equipment signs should be written correctly and clearly.
