PP-B pipe is a type of hot and cold water pipe, the price is relatively cheap, and its heat and pressure resistance performance is very different from that of PP-R. For example: using conditional grading 2, design pressure 0.6MPadn25mm pipe, PP-R pipe wall thickness 3.5mm, PP-B (PP-C) pipe wall thickness 5.1mm; design pressure 0.8MPadn25mm, PP-R pipe wall thickness 4.2mm PP-B (PP-C) cannot be used.
