Rubber Lined Electromagnetic Flowmeter Corrosion Wear Resistant

Rubber-lined electromagnetic flowmeter refers to an electromagnetic flowmeter with the inner wall of the measuring tube lined with rubber material as insulation and anti-corrosion lining.

1. Exceptional cost-effectiveness: The combination of carbon steel measuring tubes and rubber linings achieves corrosion resistance comparable to that of all-stainless steel instruments at a significantly lower cost.
2. Excellent wear resistance (especially with polyurethane): For media containing particles, rubber linings are an economical and effective solution.
3. Good elasticity and sealing performance: Good installation adaptability and compensation for minor misalignment of pipelines.
4. Smooth inner surface, anti-adhesion: Resistant to fouling, beneficial for slurry measurement.

1. Municipal and industrial water treatment (the largest market): Raw water intake, tap water transportation, industrial circulating cooling water: Chloroprene rubber lining is commonly used, which is economical and durable.
2. Untreated sewage and rainwater: Chloroprene rubber or polyurethane lining is adopted, which is resistant to wear and corrosion.
3. Mining, metallurgy and power: Slurry, coal slurry, mud, flue gas desulfurization slurry, hydraulic ash transportation: Polyurethane rubber lining is preferred due to its excellent wear resistance, and its service life is much longer than that of other linings.
4. Oil-containing water medium: Oilfield produced water, oily wastewater from oil refineries: Nitrile rubber lining is selected for its good oil resistance.
5. Chemical and papermaking (specific media): Some neutral or weakly corrosive salt solutions, pulp: Chloroprene rubber or wear-resistant polyurethane can be selected according to the specific chemical properties of the medium.

Rubber-lined electromagnetic flowmeters are a prime example of achieving a balance between high performance and low cost in electromagnetic flowmeter technology. Through the ingenious structure of "carbon steel body + special rubber lining", they have transformed the expensive all-alloy instruments into high-precision solutions that are "affordable" for most conventional water, wastewater, and slurry measurement scenarios.
