Kutsanangura nemazvo saizi yechubhu yesimbi kunofanirwa kusanganisira ma parameter akati wandei akakosha:
Dhayamita Yekunze (OD)
Dhayamita yekunze yepombi yesimbi, inowanzo ratidzwa sedhayamita yezita (DN) kana saizi yepombi yezita (NPS).
Saizi yePombi Yemazita (NPS) vs. Dhayamita Yemazita (DN)
NPS ihukuru hwezita hunobva pamainchi, nepo DN iri dhayamita yezita mumamirimita. Hukama hwekushandura huri nyore: kukosha kweDN kwakaenzana neNPS yakawedzerwa ne25.4 (mm/inch) kutenderedza mhedzisiro.
Muchokwadi, kubatana pakati peNPS neDN standards kwakavakirwa zvakanyanya pamatafura ekuenzanisa akajairwa akaiswa.
Ukobvu hwemadziro (WT)
Ukobvu hwemadziro epombi. Pamapaipi akajairwa, ukobvu hwemadziro hunowanzobatanidzwa neSchedule yepombi, semuenzaniso Schedule 40 kana Schedule 80, apo kukosha kukuru kunoratidza madziro akakora.
Kureba
Kureba kwepombi yesimbi, iyo inogona kugadziriswa kana kusarongeka, zvichienderana nezvinodiwa pakugadzirwa uye kushandiswa. Kureba kwakajairika mamita matanhatu nemamita gumi nemaviri.
Zvinhu
Mipimo yezvinhu uye mamakisi emapaipi esimbi, akadai seASTM A106 Giredhi B, API 5L Giredhi B, nezvimwewo. Mipimo iyi inotsanangura kuumbwa kwemakemikari uye hunhu hwepombi.
Maitiro
Mipimo yemapaipi ekabhoni nesimbi isina ngura inonyanya kutevedzera ASME B36.10M (simbi yakakabhoni nesimbi yesimbi) uye B36.19M (pombi yesimbi isina ngura).
Matafura eSaizi yePombi uye Matafura eGiredhi reHuremu (WGT)
inopa nzira yakajairika yekutsanangura ukobvu hwemadziro epombi pasi peMapurogiramu akasiyana, pamwe nekupatsanurwa kwemhando dzehuremu dzakadai seSTD, XS, XXS, nezvimwe.
Ukobvu hwemadziro epombi hunokanganisa zvakananga saizi yemukati uye huremu hwepombi. Ukobvu hwemadziro hwakakosha nekuti hunosarudza huwandu hwekumanikidzwa kwemukati kunogona kutsungirira pombi.
Nhamba yechirongwa
Nzira yekuratidza ukobvu hwemadziro epombi, inowanzoita seChirongwa 40 ne80, inoreva ukobvu hwemadziro hwakajairika uye hwakasimbiswa hwepombi yedhayamita yekunze yakatarwa.
Kuverengerwa kwenhamba yechirongwa kunofungidzirwa ndekwekuti:
Nekuda kwekukwanisa kwavo kutsungirira kumanikidzwa kwakajairika, mapaipi esimbi eSchedule 40 neSchedule 80 anowanzo diwa mumaindasitiri akasiyana-siyana. Sezvo mapaipi aya akagadzirirwa kutsungirira kumanikidzwa kwakakwira, anowanzo diwa muhuwandu hwakawanda kuti agutse zvinodiwa nemaindasitiri akasiyana-siyana.

Saka, muenzaniso wakakwana wetsananguro yehukuru hwepombi yesimbi ungave "NPS 6 inch, Schedule 40, ASTM A106 Grade B, Kureba 6 metres". Izvi zvinomiririra pombi yesimbi ine dhayamita yepakati ye6 inches, Schedule 40, yakagadzirwa zvichienderana nezvinodiwa zveASTM A106 Grade B, uye yakareba mamita matanhatu.
