Kuburitsa Tube:
Mukuita uku, zvinhu zve polyethylene zvinoburitswa zvakananga muchimiro chechubhu chinoenderera mberi, icho chinozoiswa papombi yesimbi.
Nzira iyi inowanzo shandiswa pamapaipi madiki ane dhayamita uye inoita kuti chifukidzo chienderane uye chirambe chichienderera mberi.
Kuburitsa mhepo:
Mukuita uku, polyethylene inoburitswa muchimiro chechidimbu yozosungirirwa pamusoro pepombi yesimbi.
Nzira iyi yakakodzera mapaipi ane dhayamita yakakura kana kuti isiri yakajairika uye inobvumira kuti pave nekuputira kunochinjika pamapaipi akaomarara kana makuru.

Ukobvu Hwose Hwekuputira
Zvichienderana nedhayamita yesimbi, ukobvu hwechikamu chekudzivirira ngura huchasiyana.
Pakukora kwese kwe3LPE layer, DIN 30670-1 inokamura makirasi matatu kuti ikwanise kugadzirisa zvinodiwa zvakasiyana zvekuvaka.n,v, uye s.
Giredhi nhamba: Kune mamiriro ezvinhu akajairwa, ukobvu hwegiredhi n hunowanzo kukwana.
Pakuputira polyethylene, ukobvu hwe1 mm hunoshandiswa zvakanyanya kudzivirira ngura, nepo ukobvu hwasara hunoshandiswa kuwedzera kugona kwemuchina wekudzivirira mutoro.
Giredhi v: Kana mutoro wemakanika ukawedzera (kutakura, kuchengetera, kuisa, mhando chaiyo, zvinodiwa zvakanyanya), ukobvu hwepurasitiki hunofanira kuwedzerwa ne0.7 mm, kureva v = n + 0.7 mm.
Giredhi: Hukobvu hwakasiyana hwekuputira hwakareba kupfuura v hunogonawo kubvumirana kuti huenderane nezvinodiwa neprojekiti chaiyo, uye ukobvu hwakadaro hwekuputira hwakagadziriswa hunonzi Grade s.
