Chuanhui Plastic Company, what is the quality of PPR pipes?

Chuanhui Plastic should be a brand in Sichuan, which is not well-known in China. 1999 is also an old brand, and its quality should be reliable. If you are from Sichuan, the ppr tube of Chuanhui should be much more cost-effective. Sichuan also has Sichuan Road, which is not bad. It mainly produces PERT pipes and floor heating pipes. By the way, PPR pipe and butterfly pipe are both good. Baidie is the drafting and revision unit of PPR pipe national standard, but Baidie is the Shanghai unit. I wonder if there is a distributor in your local area.
