ppr25 tube yog 6-point raj.
1. 25 ntawm PPR txhais tau hais tias sab nraud txoj kab uas hla yog 25 hli, tseem hu ua 6 ceg. PPR yog ib qho random polypropylene, uas txhais tau hais tias methyl sab saw ntawm polypropylene yog tsis xwm yeem thiab randomly faib nyob rau hauv lub spatial faib kev taw qhia, thaum zoo tib yam Vim hais tias cov methyl sab saw ntawm polypropylene yog irregular thiab randomly faib nyob rau hauv lub spatial faib kev taw qhia, lub zog yog me ntsis. siab dua thiab toughness yog ntau poorer.
2. No. 20 ntawm cov yeeb nkab galvanized tiag tiag yog hais txog DN20, uas yog lub nominal txoj kab uas hla thiab qhov tseeb xov yog hais txog 25 hli. Cov yeeb nkab galvanized muab faib ua kub-dip galvanized thiab txias-galvanized. Lub matrix yog txheej txheej ntawm nws tus kheej, zinc txheej yog nyias nyias, thiab cov zinc txheej tsuas yog txuas rau steel yeeb nkab 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.
