How to choose the lining material of electromagnetic flow meter

Abstract: The information on how to choose the lining material of the electromagnetic flow meter is provided by the excellent manufacturers of flow meters and flow meters. Abstract: In the production of electromagnetic flowmeter, the lining material plays a crucial role. The choice of the lining material of the electromagnetic flowmeter should be selected according to the corrosiveness, wearability and temperature of the measured medium. This article lists the main points of various materials for everyone. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to choose lining materials for electromagnetic flowmeters. Abstract: In the production of electromagnetic flowmeter, the lining material plays a crucial role. The choice of the electromagnetic flowmeter lining material should be selected according to the corrosiveness, abrasion and temperature of the measured medium. Based on this, this article lists the main functions of various materials and their applicable scope for everyone to understand. The selection of the lining material of the electromagnetic flowmeter should be selected according to the corrosiveness, abrasion and temperature of the measured medium. Hard/soft rubber can resist general weak acid and alkali corrosion, temperature resistance 65℃, soft rubber oil wear resistance, PTFE can almost resist strong acid and alkali corrosion except phosphoric acid, medium temperature can reach 130℃, but not wear. Polyurethane rubber has good wear resistance, but it is not resistant to acid and alkali corrosion, and has poor temperature resistance. The temperature of the medium is less than 65°C. The reference table is as follows: The main function of the lining material is suitable for hard rubber 1. Acetic acid, oxalic acid, ammonia water, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide. 2. Avoid strong oxidants 1. Below 65℃ 2. General salt, alkali, salt solution Soft rubber 1. It has good elasticity and good wear resistance. 2. Resistant to the corrosion of general low-concentration acid, alkali and salt medium. 3. Not resistant to corrosion by oxidizing media. 1. Below 65℃ 2. Measure general water, sewage, mud and mineral pulp. PTFE-modified polytetrafluoroethylene (PEA) 1. The material with the most stable chemical properties among plastics, which is resistant to boiling hydrochloric acid , sulfuric acid, nitric acid. Also resistant to concentrated alkalis and organic solvents. 2. Poor wear resistance and adhesion. 1. -40℃～﹢130℃ (PYFE) -40℃～﹢200℃ (PFA) 2. Strong corrosive media such as acid and alkali The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. content.
