1. Good heat insulation: due to the low data thermal conductivity of carbon steel flange, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W/MK, far less than the steel pipe and purple steel pipe, so PP-R pipe has good heat insulation.
 

2. High impact resistance: Due to the common impact strength of the butt carbon steel flange, compared with other solid wall pipes, its ring stiffness is 1.3 times that of the solid wall.

3. Good corrosion resistance: in addition to a few hydrogenation agent, it can also withstand the corrosion of various chemical media.Carbon steel welded flange has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacterial growth, no electrochemical corrosion.

4. Long service life: carbon steel butt welded flange pipe can be used for more than 50 years under additional working temperature and pressure, with ultraviolet protection and radiation protection function, so that the goods will never fade.
