Ka moralo oa pele oaPipe ea PPR, lintlha tse tharo tsa bohlokoa ka ho fetisisa li nkoa, e leng bophelo ba tšebeletso ea pipe, mocheso o sebetsang le khatello ea ho sebetsa. Lintlha tsena tse tharo li tla ama tse ling, kahoo li-parameter li tlameha ho finyella litlhoko tse boletsoeng.

Boleng ba khatello ea horePipe ea PPRe ka mamella litlhoko tsa ho ipapisa le bophelo ba moralo oa phala le mocheso sebakeng sa ho sebetsa e le ntho e hlokahalang.

Ho itšetlehile ka likarolo tse tharo tse ka holimo tsa bophelo ba tšebeletso, mocheso oa tšebeliso le khatello ea tšebeliso, re ka etsa qeto ea melao e 'meli:

1. Haeba bophelo bo tloaelehileng ba tšebeletso ea pipe ea PPR bo behiloe hoo e ka bang lilemo tse 50, mocheso o phahameng oa tikoloho ea ho sebetsa oa pipe e entsoeng, o fokotsa khatello e tsoelang pele ea ho sebetsa eo PPR e ka e mamellang, le ka tsela e fapaneng.

2. Haeba mocheso oa moralo oa pipe ea PPR o feta 70 ℃, nako ea ho sebetsa le khatello e tsoelang pele ea ho sebetsa ea pipe ea PPR e tla fokotseha haholo. Ke ka lebaka la ts'ebetso e ntle ea liphaephe tsa PPR tse ka tlase ho 70 ° C moo lipeipi tsa PPR li fetohang tse chesang haholo le tse batang.lipeipi tsa metsi, hobane mocheso o akaretsang oa metsi a chesang a lapeng o ka tlase ho 70°C.

Ho na le mefuta e 'meli ea lipeipi tsa PPR: pipe ea metsi a batang le pipe ea metsi a chesang. Phapano ke efe?

Lipeipi tsa metsi a batang li batla li le tšesaane. Ha e le hantle, ho kgothaletswa ho reka liphaephe tsohle tsa metsi a chesang, hobane lerako la liphaephe tsa metsi a chesang le batla le le teteaneng 'me khatello ea khatello e ntle. Ho na le mefuta e 'meli ea malapa a tloaelehileng: 6 e ikarabellang (bophara bo ka ntle ba 25 mm) le 4 e ikarabellang (bophara bo ka ntle ba 20 mm).

Haeba u lula mokatong o tlaase, khatello ea metsi e phahame, u ka sebelisa phala e teteaneng ea lintlha tse 6, e le hore metsi a phallo e be a maholo 'me a se ke a potlaka haholo. Haeba u lula mokatong o phahameng, joalo ka mong'a ea boletsoeng ka holimo, ea lulang mokatong oa 32, o tlameha ho kopanya liphaephe tse teteaneng le tse tšesaane. Ho khothalletsoa ho sebelisa 6 bakeng sa phala e kholo le 4 bakeng sa pipe ea lekala ho qoba khatello e sa lekaneng ea metsi lapeng.
