Detail features

A： Electrode material and applicable scope

316L is used for measuring slightly corrosive media such as water, sewage, or inorganic or organic acids.

2 Hastelloy B (HB) has good corrosion resistance to all concentrations of hydrochloric acid below boiling point, as well as to non oxidizing acids, bases, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids.

3 Hastelloy C (HC) is resistant to corrosion by oxidizing acids such as nitric acid, mixed acids, or solutions, as well as mixed media of chromic acid and sulfuric acid; Also resistant to oxidation

Corrosion caused by factors such as Fe++, Cu++, or other oxidants, such as corrosion caused by hypochlorite seawater above room temperature.

4.Titanium (Ti) can withstand corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc; Not resistant to the corrosion of relatively pure reducing acids (such as sulfuric acid, hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fe+++, Cu++), the corrosion resistance is greatly reduced.

5.Tantalum (Ta) has excellent corrosion resistance, similar to glass. Except for hydrofluoric acid, fuming sulfuric acid, fuming nitric acid, and alkali, it can withstand corrosion from almost all chemical media (including boiling point hydrochloric acid, nitric acid, and sulfuric acid). Not resistant to corrosion in alkali.

Platinum iridium alloy is suitable for almost all chemical substances, but not for aqua regia and ammonium salts.

Tungsten carbide has good wear resistance and can be used for measuring high wear media, such as pulp, slurry, etc.

B: Lining material, performance, and scope of application

1. chloroprene rubber (CR) 1. Resistant to oil, solvents, oxidation, and general acidic, alkaline, and oxidizing media such as 1.0 ℃~80 ℃ non strong acid, strong alkali, and strong oxidizing media such as 1.0 ℃~80 ℃ non strong acid, strong alkali, and strong oxidizing media. 2. Can measure mud and water.

2. Silicone fluororubber (FVMQ) 2. It has excellent elasticity and wear resistance, but its cold resistance is higher than that of non abrasive and non corrosive media at -25 ℃~150 ℃ 2. It is suitable for high-temperature fluid working conditions.

3 Polyurethane rubber (PU) 1. Good low temperature resistance, can still work normally at -55 ℃

2. It has outstanding heat resistance and can work for a long time at 180 ℃. 1.-25℃~60℃
