PP Compression Female Coupling Manufacturers

Sometimes consumers have no way to tell the quality of PPR water pipes. Just like adding calcium carbonate to PPR water pipes, there is no difference at all from the appearance of the water pipes. However, among small-scale manufacturers, doping calcium carbonate in the production of PPR water pipes is a common phenomenon.

Ningbo Sunplast Pipe Co., Ltd has been focusing on manufacturing of plastic piping systems for more than 15 years.
