Ia mautinoa e fai atu tolu, e tatau ona: PPR, PVC, PE
1. O paipa palasitika masani faʻaaogaina o: PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyethylene faʻafefe vevela), PE (polyethylene) \HDPE (faʻamalosia maualuga polyethylene) ethylene), ma isi.
Lona lua, o le tele o paipa palasitika e masani ona faʻaalia i tulaga o le lautele i fafo.E pei ole PPR tube: De63
3. Le soifua tautua oMF POLO VALVE X9011ua fuafuaina e tusa ai ma le GB / T18252-2000 "Faiga paipa palasitika - Fuafuaga o le malosi hydrostatic umi o paipa thermoplastic e ala i le extrapolation".Ole auala lea ole fa'avasegaina fa'afuainumera ma le vavalo o le malosi umi o meatotino o mea vevela po'o tala mai fa'ai'uga o su'ega o le malosi o le hydrostatic o paipa.*O le tele o mea o loʻo taʻua i luga e faʻaaoga ai lenei metotia e faʻatatau, i lalo o le tulaga vevela o le 20 ℃, o le paipa palasitika e masani ona i ai le umi o le 50 tausaga.
Lona fa, o mea faʻapipiʻi mo paipa palasitika o se masini faʻapipiʻi tui, lea e faʻapipiʻiina i paipa e le masini tui.
5. E masani ona lua auala e faʻafesoʻotaʻi ai paipa palasitika: liusua vevela ma kelu.
6. O tulaga masani mo paipa palasitika e aofia ai:
1. PPR (polypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3
2. PVC (polyvinyl chloride): GB/T10002.1-2006, GB/T10002.2-2003
3. PE (polyethylene): GB15558, GB/T13663
4. HDPE (Fa'asiliina High Density Polyethylene): GB/T19472.2-2004
O paipa palasitika e masani lava ona aofia ai le PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyethylene vevela), PE (polyethylene), HDPE (faʻaleleia le maualuga o le polyethylene), ma isi. polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE) ma isi polymers.
O paipa palasitika o se faaupuga lautele mo paipa e faia i mea palasitika.O paipa palasitika o loʻo i ai uiga o le mama mama, tumama ma le saogalemu, faʻafefe vai laiti, faʻasaoina o le malosi, faʻasaoina o uʻamea, faʻaleleia atili o le siosiomaga ola, ola umi o le auaunaga, saogalemu ma le faʻaogaina, ma isi, ma e faʻamanuiaina e le au faʻainisinia pipeline.I le 10 tausaga ua tuanaʻi, faʻamalosia e loʻu atunuʻu macroeconomic atinaʻe, o loʻu atunuu paipa palasitika ua oʻo i le atinaʻe vave i lalo o le talaaga o le atinaʻeina tele o mea faufale vailaʻau.I le 2010, o le gaosiga a le atunuʻu o paipa palasitika na sili atu i le 8 miliona tone, lea na maua ai e Guangdong, Zhejiang ma Shandong le 42% o le gaosiga.O paipa palasitika e tele mea lelei nai lo paipa uʻamea masani ma paipa sima i le tele o fanua, o lea ua faʻaaogaina lautele i le tele o eria.
