Kumklamo wokuqala we-Ipayipi le-PPR, izici ezintathu ezibucayi kakhulu zicatshangelwa, okungukuthi impilo yesevisi yepayipi, izinga lokushisa lokusebenza kanye nokucindezela kokusebenza. Lezi zici ezintathu zizothintana, ngakho amapharamitha kufanele ahlangabezane nezidingo ezicacisiwe.

Inani lokucindezela ukuthiIpayipi le-PPRingamelana nezidingo ezisekelwe empilweni yokuklama yepayipi kanye nezinga lokushisa endaweni yokusebenza njengemfuneko.

Ngokusekelwe kumingcele emithathu engenhla yokuphila kwesevisi, izinga lokushisa lokusetshenziswa nengcindezi yokusebenzisa, singaphetha imithetho emibili:

1. Uma isilinganiso sempilo yesevisi yepayipi le-PPR sihlelwe ukuthi sibe yiminyaka engaba ngu-50, izinga lokushisa lendawo yokusebenza yepayipi eliklanyelwe liphezulu, liyancipha ingcindezi yokusebenza eqhubekayo i-PPR engakwazi ukumelana nayo, futhi ngokuphambene nalokho.

2. Uma izinga lokushisa lomklamo wepayipi le-PPR lidlula i-70 ℃, isikhathi sokusebenza nokucindezela okuqhubekayo kokusebenza kwepayipi le-PPR kuzoncishiswa kakhulu. Kungenxa kanye nokusebenza kahle kwamapayipi e-PPR angaphansi kuka-70°C okwenza amapayipi e-PPR abe iwona ajwayelekile ashisayo futhi abandayo.amapayipi amanzi, ngoba izinga lokushisa elivamile lamanzi ashisayo asekhaya lingaphansi kuka-70°C.

Kunezinhlobo ezimbili zamapayipi we-PPR: ipayipi lamanzi abandayo kanye nepayipi lamanzi ashisayo. Uyini umehluko?

Amapayipi amanzi abandayo mancane kakhulu. Eqinisweni, kunconywa ukuthenga wonke amapayipi amanzi ashisayo, ngoba udonga lwamapayipi amanzi ashisayo luningi futhi ukumelana nokucindezela kuhle. Kunezinhlobo ezimbili zemizi ejwayelekile: 6 ophethe (ububanzi bangaphandle 25 mm) kanye 4 ophethe (ububanzi bangaphandle 20 mm).

Uma uhlala endaweni ephansi, ukucindezela kwamanzi kuphezulu, ungasebenzisa ipayipi enamaphuzu angu-6, ukuze ukugeleza kwamanzi kukhulu futhi kungasheshi kakhulu. Uma uhlala endaweni ephakeme, njengomnikazi oshiwo ngenhla, ohlala esitezi sama-32, kufanele uhlanganise amapayipi awugqinsi namancane. Kunconywa ukusebenzisa i-6 yepayipi eyinhloko kanye ne-4 yepayipi yegatsha ukugwema ukucindezela kwamanzi okwanele ekhaya.
