1、application Used in conjunction with a two-section thermocouple / RTD and bimetal thermometer to protect the thermocouple / RTD and bimetal thermometer from working properly. It can also be used in high pressure and high flow applications. 2、characteristics
Full reference to IEC international standard design Blind hole processing, high pressure resistance Manufactured and installed at the same time as the equipment Different pressure levels can meet different needs.
3、the main technical parameters Nominal pressure: generally refers to the static external pressure that can be withstood by the protective tube at normal temperature without breaking. The allowable working pressure is related not only to the material, diameter, and wall thickness of the protective tube, but also to its structural form, installation method, and flow rate and type of the measured medium. Water pressure test: When the pressure resistance and leakage inspection of the protection pipe are required, the protection pipe shall be tested. The test pressure is 15 times the pressure rating of the protection tube. X-ray flaw detection test: When there is a requirement for the inspection of the wall thickness and eccentricity of the protection pipe, it shall be inspected according to the requirements of the user.4、model naming method: T H 02 A B | Hot Installation Casing | Connection Form | Serial number | Casing Material | 01 Threaded connection 02 Flanged connection 03 Welding type | A | No (unlabeled) 1Cr18Ni9Ti A 304 B 316 C 316L D Other |
