1. Vinthu vya Imperial
Paipi ya chisulo cha imperial yikulongosoreka na msumba ukuru wa "DN." Kukura kukusazgapo DN15 (chiŵiya cha 4-inch), DN20 (chiŵiya cha 6-inch), DN25 (chitoliro cha 1-inch), DN32 (1-inch 2-inch chitoliro), DN40 (chiŵiya cha 1.5-inch), DN50 (chiŵiya cha 2-inch), DN65 (chiŵiya cha 2.5-inch), DN80 (chiŵiya cha masentimita 3), DN100 (chiŵiya cha 3-inch), DN125 (chitoliro cha masentimita 5), DN150 (chitoliro cha masentimita 6), DN200 (chitoliro cha masentimita 8), na DN250 (chitoliro cha masentimita 10). Mwachiyelezgero, chitoliro cha maji cha DN25 (25 mm) chikuyana waka na chitoliro cha 1-inch cha 1-inch, icho chikuchemekaso kuti chitoliro cha 8-inch pambere ŵasilikari ŵa Liberation Army ŵandafike. Payipi ya maji ya DN15 yikuyana na chitoliro cha 1/2-inch, icho chikuchemekaso kuti chitoliro cha masentimita 4 pambere ŵasilikari ŵa kufwatulika ŵandambe. Mwachiyelezgero, chitoliro cha maji cha DN20 ni 3/4 "British standard, iyo yikumanyikwaso kuti chitoliro cha masentimita 6 pambere Kufwatulika Kufwatulika.
2. Miyezo ya Pachanya
Chitoliro cha chisulo cha pa charu chose chikukhazikika pa kugaŵa inchi mu vigaŵa vichokovichoko. Viyezgelero vikusazgapo 1/8, 1/4, na 3/8 inches, vyakuyana na mapaipi gha 1-inch na 7-inch agho ghakumanyikwa chomene. Makuliro ghachoko ghakulongosoreka nga ni 1/16, 1/32, na 1/64, ghachali mu masentimita. Usange denominator na numerator yingacepeskeka (mwaciyelezgero, nambara ni 2, 4, 8, 16, panji 32), yikwenera kucepeskeka.
3. Kupenda Kwakupindika kwa Steel
Mafomula ghakupenda kulemera kwa mitundu yakupambanapambana ya chitoliro cha chisulo chikupambana. Pansi, MIAGOO yizamulongosora mwachidule nthowa zinandi zakumanyikwa zakupimika:
Kulemera kwa Steel (gg)=0.00617 x Diameter x Utali wa x;
Square Steel Kulema (kg)= 0.00785 x Mzere wa Side x Side x Utali;
Flat Steel Kulemera (gg)=0.00785 x Kutesi x Kutali.
