Model classification of anticorrosive hot pair
2011-12-31 10:15:27

是专门为各种腐蚀性介质的温度测量生产制造的。 Corrosion-resistant thermocouples are specially manufactured for temperature measurement of various corrosive media. Depending on the corrosion characteristics of the medium, different anticorrosive materials can be selected. Some are special anticorrosive products specially developed for the special physical and chemical properties of a certain medium.

And according to the needs of users, the fixed installation device and the junction box can also have anti-corrosion performance, so as to achieve the full anti-corrosion performance requirements. It is suitable for high temperature and corrosive occasions in various production processes. It is widely used for temperature measurement in petroleum industry, glass smelting and ceramic industry.

分类: Anti-corrosion hot spot classification:


1, 304, 316L material protection tube


Suitable occasions: used for industrial, domestic water, sewage and other weakly corrosive media, suitable for petroleum, chemical, steel and other industries and municipal, environmental protection and other fields


2, Hastelloy C material protection tube


Use occasions: resistant to the corrosion of non-oxidizing acids, such as nitric acid, mixed acids, mixed media, and the corrosion of oxidizing salts under FE +++, CU ++ or containing other oxidants, such as hypochlorite solutions above normal temperature, seawater corrosion

3.Titanium protection tube


Use occasions: corrosion of 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, hydrochloric acid), but if the acid contains oxidants (such as nitric acid, FE +++,

CU ++), the corrosion is greatly reduced


4.Protective tube made of PTFE


Application: A kind of plastic with the most stable chemical properties. It is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia. It is also resistant to concentrated alkali and various organic solutions. Not resistant to the corrosion of chlorine trifluoride, high temperature chlorine trifluoride, high-speed liquid fluorine, and ozone.


型号: Anti-corrosion hot spot model:


Same as general thermocouple, please specify the material of protection tube when selecting
