Pombi yesimbi inoshandiswa kutamisa mvura nehupfu, kuchinjana kupisa uye kugadzira zvikamu zvemakanika nemagaba, uye zvakare imhando yesimbi isingadhuri. Kushandisa mapaipi esimbi kugadzira magrid ekuvaka, mbiru uye zvinotsigira zvemakanika kunogona kuderedza huremu nekuchengetedza 20-40% yesimbi, uye kunogona kuita kuti pave nekuvaka kwakafanana nefekitori. Ndeapi marudzi emapaipi esimbi anowanzo kuwanikwa? Pombi yesimbi yakakura sei? Chinyorwa chino chinoazivisa rimwe nerimwe.
Govanisa inchi imwe kuita zvikamu zvisere zvakaenzana; 1/8 1/4 3/8 1/2 5/8 3/47/8 inches. Yakaenzana nechubhu ye1-point yakajairika kune chubhu ye7-point, uye saizi diki dzinomiririrwa ne1/16, 1/32, 1/64, uye yuniti ichiri mainji. Kana denominator nenumerator zvichigona kuderedzwa (sekuti numerator iri 2, 4, 8, 16, 32), inofanira kuderedzwa.
Chiratidzo chemasendimita chinoratidzwa nematanho maviri mukona yepamusoro yekurudyi, senge 1/2". Semuenzaniso, pombi yemvura yeDN25 (25mm, yakafanana neiri pazasi) ndiyo pombi yemvura yeImperial 1" , uye zvakare ndiyo pombi yemvura ye8-point isati yasunungurwa. Pombi yemvura yeDN15 ndiyo pombi yemvura yeImperial 1/2" , iyo zvakare ndiyo pombi yemvura ye4-point isati yasunungurwa. Semuenzaniso, pombi yemvura yeDN20 ndiyo pombi yemvura yeImperial 3/4" , iyo zvakare ndiyo pombi yemvura ye6-point isati yasunungurwa.
Saizi DN15 (machubhu mana), DN20 (machubhu matanhatu), DN25 (chubhu imwe yeinch), DN32 (machubhu maviri einch imwe), DN40 (chubhu imwe yeinch imwe nehafu), DN50 (chubhu imwe yeinch imwe), DN65 (chubhu imwe yeinch imwe nehafu), DN80 (chubhu ine inch imwe), DN100 (chubhu ine inch imwe), DN125 (chubhu ine inch imwe 5), DN150 (chubhu ine inch imwe 6), DN200 (chubhu ine inch imwe 8), DN250 (chubhu ine inch imwe 10), nezvimwewo.
