1, the application
3, the main technical parameters
Nominal pressure: generally refers to the room temperature, protect tube can withstand the static pressure and not burst. Allows working pressure not only with protecting tube material, diameter, wall thickness, and its structure, installation method, and the measured medium velocity, species.
Water pressure experiment: to protect the pipe pressure and leak check when required, must be tested for protecting tube. Test pressure to protect the pipe pressure levels of 15 times. X-ray flaw detection test: to protect the pipe wall thickness, eccentricity and so on project inspection requirements, shall be checked according to the requirements of customers.
