1. He aha te pēhanga o te paipa PE?

E ai ki ngā whakaritenga paerewa ā-motu o GB/T13663-2000, ko te pēhanga oNgā paipa PEka taea te wehewehe ki ngā taumata e ono: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, me te 1.6MPa. Nā, he aha te tikanga o ēnei raraunga? He tino māmā: Hei tauira, 1.0 MPa, ko te tikanga ko te pēhanga mahi noa o tēnei momoNgā Hononga Hdpeko te 1.0 MPa, koinei te mea e kiia nei e tātou ko te pēhanga 10 kg. Ko te tikanga, i roto i te whakamātautau pēhanga o mua, e ai ki ngā whakaritenga o ngā paerewa ā-motu, me pēhanga 1.5 ngā wā. Puritia te pēhanga mō ngā hāora 24, arā, ka mahia te whakamātautau me te pēhanga wai o te 15 kg.

2. He aha te uara SDR o te paipa PE?

Ko te uara SDR, e mōhiotia ana ko te ōwehenga rahi paerewa, he ōwehenga o te diameter o waho ki te matotoru o te pakitara. I te nuinga o te wā ka whakamahia e mātou te uara SDR hei tohu i te whakatauranga pēhanga kirokaramu. Ko ngā uara SDR e rite ana o ngā taumata e ono o te 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, me te 1.6MPa ko: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Tuatoru, ko te pātai mō te diameter o te paipa PE

Ko te whānui o ngā paipa PE he 20mm-1200mm. Ko te whānui e kōrerohia ana i konei e pā ana ki te whānui o waho. Hei tauira, ko te paipa PE o De200 1.0MPa he paipa PE me te whānui o waho o 200, te pēhanga o 10 kg, me te matotoru o te pakitara o 11.9 mm.

Tuawhā, ko te tikanga tatau i te taumaha mita o te paipa PE

Ina tae mai te tini o ngā kaiwhakamahi ki te pātai mō te utu oNgā Hononga Paipa Hdpe, ka pātai mai ētahi e hia te utu o te kirokaramu, me whakamahi tātou i tētahi raraunga i konei - te taumaha mita.

Ka tuhia e mātou ētahi tātai hei tatau i te taumaha mita o ngā paipa PE. Ka maumahara pea ngā hoa e hiahia ana ki ēnei. He mea āwhina mō ngā mahi a meake nei:

Taumaha mita (kg/m)=(diameter o waho-matotoru pakitara)*matotoru pakitara*3.14*1.05/1000

Āe, koinā katoa ngā kōrero o te rā nei. Mō ētahi atu mōhiotanga e pā ana ki ngā paipa PE, tēnā koa whakarongo mai ki a mātou. Hono atu ki a Shentong ki te toa i te mākete, nau mai ki te uiui.
