Ipayipi lensimbi lisetshenziselwa ukudlulisa uketshezi kanye nempuphu, ukushintshanisa ukushisa nokukhiqiza izingxenye zemishini kanye nezitsha, futhi futhi luhlobo lwensimbi engabizi. Ukusebenzisa amapayipi ensimbi ukukhiqiza amagridi esakhiwo sesakhiwo, izinsika kanye nezisekelo zemishini kunganciphisa isisindo futhi konge u-20-40% wensimbi, futhi kungenza ukwakhiwa komshini okufana nokwefektri. Yiziphi izinhlobo zamapayipi ensimbi ezivame ukutholakala? Ungakanani usayizi wepayipi lensimbi? Lesi sihloko sizethula ngasinye ngasinye.
Hlukanisa i-intshi eli-1 libe izingxenye ezilinganayo eziyi-8; 1/8 1/4 3/8 1/2 5/8 3/47/8 amayintshi. Lilingana nepayipi elijwayelekile elinamaphuzu angu-1 nepayipi elinamaphuzu angu-7, kanti osayizi abancane bamelelwa yi-1/16, 1/32, 1/64, futhi iyunithi isengama-intshi. Uma i-denominator kanye ne-numerator kungancishiswa (njengokuthi i-numerator ingu-2, 4, 8, 16, 32), kufanele kuncishiswe.
Isibonakaliso samasentimitha siphawulwe ngemivimbo emibili ekhoneni eliphezulu kwesokudla, njenge-1/2". Isibonelo, ipayipi lamanzi le-DN25 (25mm, elifanayo ngezansi) liyipayipi lamanzi elingu-1" eliyi-Imperial, futhi liyipayipi lamanzi elinamaphoyinti angu-8 ngaphambi kokukhululwa. Ipayipi lamanzi le-DN15 liyipayipi lamanzi elingu-1/2" eliyi-Imperial, eliphinde libe yipayipi lamanzi elinamaphoyinti angu-4 ngaphambi kokukhululwa. Isibonelo, ipayipi lamanzi le-DN20 liyipayipi lamanzi elingu-3/4" eliyi-Imperial, eliphinde libe yipayipi lamanzi elinamaphoyinti angu-6 ngaphambi kokukhululwa.
Usayizi DN15 (amashubhu angu-4), DN20 (amashubhu angu-6), DN25 (ishubhu elingu-1 intshi), DN32 (amashubhu angu-1 intshi angu-2), DN40 (ishubhu elingu-1 intshi nengxenye), DN50 (ishubhu elingu-2 intshi), DN65 (ishubhu elingu-2 intshi nengxenye), DN80 (ishubhu elingu-3 intshi), DN100 (ishubhu elingu-4 intshi), DN125 (ishubhu elingu-5 intshi), DN150 (ishubhu elingu-6 intshi), DN200 (ishubhu elingu-8 intshi), DN250 (ishubhu elingu-10 intshi), njll.
