Characteristics
1. Anti corrosionthermocoupleAdopting multi-layer anti-corrosion (anti-corrosion)thermal resistanceThe anti-corrosion layer protection pipe is usually a thick walled 316L or 304L steel pipe with an overall sintered polytetrafluoroethylene layer and wear-resistant anti-corrosion layer. The anti-corrosion effect and service life have been verified by many domestic enterprises through long-term use.
2. Anti corrosionthermocoupleOur company adopts the most advanced overall sintering process in China to sinter the polytetrafluoroethylene anti-corrosion layer, which solves the problem of joint leakage that cannot be avoided by other manufacturing processes. The application of this technology enables our company to prevent corrosionthermal resistanceThe average service life of other anti-corrosion products (in an environment without significant wear and tear) exceeds one year.
3. There are often high velocity particles in the measured medium present at the site of usethermal resistanceSevere erosion of the anti-corrosion layer, our company's anti-corrosion measuresthermocoupleThere is also a layer of wear-resistant material outside the anti-corrosion layer, which can effectively extend the service life of the anti-corrosion layer by 8-10 times in environments with erosion, different from other similar anti-corrosion materials in Chinathermocouple.
3. Selection of protective tubes and corrosion resistance performance
1. Stainless steel (0Cr18Ni12Mo2Ti) protective pipe: used for weakly corrosive media such as industrial water, domestic water, sewage, etc., suitable for industrial sectors such as petroleum, chemical, steel, as well as municipal and environmental protection fields.
2. Hastelloy B protective tube: It has good corrosion resistance to all concentrations of hydrochloric acid below boiling point, as well as to non chlorinated acids, bases, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids.
3. Hastelloy C protective tube: It can withstand corrosion from non oxidizing acids such as nitric acid, mixed acids, or mixed media of chromic acid and sulfuric acid, as well as corrosion from oxidizing salts Fe++, Cu++, or other oxidants such as hypochlorite solutions above room temperature and seawater.
4. Titanium protective tube: capable of withstanding corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including fuming sulfuric acid), organic acids, and alkalis. Not resistant to the corrosion of relatively pure reducing acids (such as quicksand and hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fe+++, Cu++), the corrosion is greatly reduced.
5. Polytetrafluoroethylene protective tube: It is the most chemically stable plastic, capable of withstanding boiling hydrochloric acid, sulfuric acid, nitric acid, and aqua regia, as well as concentrated alkali and various organic solvents. Not resistant to corrosion from chlorine trifluoride, high-temperature chlorine trifluoride, high-speed liquid fluorine, liquid oxygen, and ozone.
