ppr25 tube is a few points

The ppr25 tube is a 6-point tube.

1. 25 of PPR means that the outer diameter is 25mm, also known as 6 branches. PPR is a random polypropylene, which means that the methyl side chain of polypropylene is irregular and randomly distributed in the spatial distribution direction, while ordinary Because the methyl side chain of polypropylene is irregular and randomly distributed in the spatial distribution direction, the strength is slightly higher and the toughness is much poorer.

2. No. 20 of the galvanized pipe actually refers to DN20, which is the nominal diameter and the actual thread is about 25 mm. The galvanized pipe is divided into hot-dip galvanized and cold-galvanized. The matrix is independently layered, the zinc layer is relatively thin, and the zinc layer is simply attached to the steel pipe matrix.

3. Ppr pipe φ20 is equivalent to the specification connection of galvanized pipe dn15. The specification outer diameter of dn15 is 21.3mm. PP-R has good weldability. The pipe fittings can be connected by hot melt and electrofusion, which is easy to install and the strength of the connecting part is greater than The strength of the pipe itself, the interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together.
