How to install asbestos rubber mats:
1. Remove all gasket fragments on the flange surface. For best results, 1. Assemble the old gasket. Use a metal flange scraper, some spray strip remover and a wire brush, then check the flange for damage. Ensure that the appearance and smoothness of the appearance meet the requirements.
2. Use the thinnest gasket possible. However, for some warped bows or severely dented flanges, a slightly thicker gasket is required.
A larger compressive load needs to be applied to the shim. 3. Try to use a ring gasket. Because the full planar gasket has a larger surface area.
Do not use wet anti-adhesive agents. Talc is the best choice. 4. Use a dry anti-adhesive. Graphite and mica are also possible. Metal-based anti-adherents cannot be used because the particles may accumulate in the seal's exterior defects, causing the flange surface to be too smooth and fail.
Device
This is very important. Note: Properly cut the annular gasket according to the specification ANSI, 1 Place the gasket on the flange and center it with the flange. When the flange is a convex flange. When the bolt is placed, it will be centered automatically.
Hard flat washers and fasteners that are well lubricated. 2. Use a torque wrench. To ensure the correct initial load.
The bolts must be tightened in the correct order. 3. To evenly press the gasket when tightening the bolt.
When tightening for the first time, 4. Follow the correct bolt tightening sequence. All bolts shall only apply one-third of the torque of the recommended bolt torque.
All safety regulations should be observed during this process. 5. Tighten in the correct tightening sequence within 1224 hours after the first tightening. Includes locking and locking procedures.
These can cause the gasket to fail to seal. Asbestos rubber mat installation, 6. Never use liquid or metal based anti-adhesives or lubricants on the gasket. Rubber pad mounting method, PTFE pad mounting
