Polytetrafluoroethylene (F4) |
It is a plastic with stable chemical properties. It can withstand boiling hydrochloric acid, sulfuric acid, concentrated alkali and various organic solvents. |
70℃ |
100℃ 150℃ (special order required) |
1. Strongly corrosive media such as concentrated acid and alkali. 2. Sanitary media. |
|
Fluorinated ethylene propylene (F46) |
Same as F4, but with higher wear resistance and negative pressure resistance than F4. |
Same as above |
|
|
|
Polyvinyl fluoride (Fs) |
The upper limit of applicable temperature is lower than that of polytetrafluoroethylene, but the cost is also lower. |
80℃ |
|
|
|
Neoprene |
1. Excellent elasticity, high tearing force, good wear resistance. 2. Resistant to corrosion by general low-concentration acid, alkali, and salt media, but not resistant to corrosion by oxidizing media. |
80℃ 120℃ (special order required) |
Water, sewage, slightly abrasive mud and slurry. |
|
|
Polyurethane rubber |
1. Excellent wear resistance. 2. Poor corrosion resistance. |
80℃ |
Neutral and highly abrasive ore slurry, coal slurry, mud |
|

Orchid species |
Scope of application |
|
Grounding flange (or grounding ring) |
Suitable for non-conductive pipes such as plastic pipes, but not required for sensors with ground electrodes. |
|
Imported protective flange |
It is used when the medium is highly abrasive. |
Electrode selection

Electrode Materials |
Corrosion and wear resistance |
|
Stainless steel 0Crl8Nil2M02Ti |
Used for weakly corrosive media such as industrial water, domestic water, sewage, etc., suitable for industrial sectors such as petroleum, chemical industry, steel, as well as municipal administration, environmental protection and other fields. |
|
Hastelloy B |
It has good corrosion resistance to hydrochloric acid of all concentrations below the boiling point, and is also resistant to corrosion by non-chlorinated acids, alkalis, and non-oxidizing salt solutions such as sulfuric acid, phosphoric acid, and organic acids. |
|
Hastelloy C |
It can resist corrosion from non-oxidizing acids such as nitric acid, mixed acid, or mixed medium of chromic acid and sulfuric acid, as well as corrosion from oxidizing salts such as Fe, Zn, Cu, or other oxidants such as hypochlorite solution above room temperature and seawater. |
|
titanium |
It is resistant to corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including fuming sulfuric acid), organic acids, and alkalis. It is not resistant to corrosion from purer reducing acids (such as sulfuric acid and hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fc++, Cu++), the corrosion is greatly reduced. |
|
Tantalum |
It has excellent corrosion resistance and is very similar to glass. It can resist corrosion from almost all chemical media (including boiling hydrochloric acid, nitric acid and sulfuric acid below 150°C) except fuming sulfuric acid and alkali. It is corrosion-resistant in alkali. |
|
Platinum/Titanium Alloy |
It is resistant to almost all chemical media, but is not suitable for aqua regia and ammonium salts. |
|
Stainless steel coated with tungsten carbide |
Used for non-corrosive and highly abrasive media. |
|
Note: Due to the wide variety of media, their corrosiveness is affected by complex factors such as temperature, concentration, flow rate, etc., so this table is for reference only. Users should make their own choices based on actual conditions, and if necessary, corrosion resistance tests should be conducted on the selected materials, such as hanging plate tests. |
