Product details
characteristic
- All designed in accordance with IEC international standards
- Blind hole processing, high pressure resistance
- Manufacturing and installation simultaneously with the equipment
- Different pressure levels can meet different needs.
Main technical parameters
Nominal pressure: generally refers to the static external pressure that the protective tube can withstand at room temperature without breaking. The allowable working pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to its structural form, installation method, and the flow rate and type of the measured medium.
Water pressure test: When there are requirements for the pressure resistance and leakage inspection of the protective tube, the protective tube must be tested. The test pressure is 15 times the pressure resistance level of the protective tube. X-ray flaw detection test: When there are requirements for checking the wall thickness, eccentricity, and other items of the protective tube, the inspection must be carried out according to the user's requirements.
