The lining material should be selected based on the aggressiveness, abrasion and temperature of the medium being measured.
How to accurately choose the lining material. The lining material should be selected based on the aggressiveness, abrasion and temperature of the medium being measured.
1. Rubber. It has good elasticity, high tearing force, good wear resistance, and is resistant to erosion by general weak acids and alkalis. It can measure water, sewage, mud and mineral slurry, etc.
2. Polyurethane. It has good wear resistance, poor acid and alkali resistance, and can measure coal slurry, mud and mineral slurry with neutral and strong wear.
3. Polytetrafluoroethylene. It is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali and various organic solvents. It has good wear resistance but poor bonding performance.
The electromagnetic flowmeter grounding ring is connected to both ends of the flow sensor in a plastic pipe or an insulating-lined metal pipe. Their corrosion resistance requirements are lower than those of electricity. Certain corrosion is allowed and must be replaced regularly. Acid-resistant steel or Hastelloy is usually used. Due to large size and economic considerations, precious metals such as tantalum and platinum are rarely used. If the metal process pipe is in direct contact with the fluid, a grounding ring is not required.
