1. Hurefu husingagumi (urefu huzhinji)
Mapaipi esimbi asina musono anowanzo siyana pakureba, anodaidzwa kunzi hurefu husingagumi mukati mechikamu chechiyero. Hurefu husingagumi hunonziwo hurefu hwemazuva ose (kuburikidza nemutongi). Somuenzaniso, kureba 159 * 4.5galvanized seamless simbi pombikazhinji i8 ~ 12.5

2. Yakagadziriswa urefu
Cheka kusvika kuhukuru hwakatarwa maererano nezvinodiwa zvekurongeka kunonzi fixed-length. Paunenge uchiendesa zvinoenderana nehurefu hwakatarwa-hurefu, iyo galvanized seamless simbi pombi inofanirwa kuve nehurefu hwakatsanangurwa nemutengi muchibvumirano chekuraira. Semuyenzaniso, kana kondirakiti ichitaura kuti kuendesa kunobva pakureba kwakatarwa kwe6m, zvinhu zvakaunzwa zvinofanirwa kureba 6m. Chero chinhu chipfupi pane 6m kana kureba kupfuura 6m hachikodzeri. Asi chaizvoizvo, hazvibviri kuti kutakura kuve kwese 6m kureba, saka zvinorehwa kuti kutsauka kwakanaka kunobvumirwa, asi kukanganisa kusina kunaka hakubvumirwi. (Kana kureba kwakagadziriswa kuri pasi pe6m, kutsauka kunobvumirwa kunowedzerwa kusvika +30mm; kana kureba kwakagadziriswa kwakakura kupfuura 6m, kutsauka kunobvumirwa kunowedzerwa kusvika +50mm)

3. Nguva
Iyo yakagadziriswa saizi yakachekwa kuita akakosha akawanda zvichienderana nehurongwa zvinodiwa inonzi kaviri mutongi. Kana uchiendesa muhurefu hwakawanda, kureba kwepombi yesimbi isina musono inounzwa kunofanirwa kunge iri nhamba yakakura yehurefu (inonzi kureba imwe chete) inotsanangurwa muchibvumirano cheodha nemutengi (pamwe nesaha yakachekwa). Semuenzaniso, mutengi anoda mutongi mumwechete kureba kwe2m muchibvumirano chekuraira, ipapo kureba i4m kana yakachekwa kuita mutongi kaviri, uye 6m kana yakachekwa kuita mutongi katatu, pamwe nekucheka kumwe kana maviri zvakateerana. .
Huwandu hwemasaha akachekwa hunotsanangurwa muyero. Kana mutongi wembiri akaendeswa, kutsauka kwakanaka chete kunobvumirwa, uye kukanganisa kusina kunaka hakubvumirwi.

4. Mutongi mupfupi
Kureba kwakaderera pane kuderera kwemuganho wehurefu husingaverengeki hunotsanangurwa nechiyero, asi kwete pasi pehurefu hunobvumirwa hupfupi hunonzi hurefu hupfupi. Semuenzaniso, iyo fluid yekutakura simbi pombi mwero inotaura kuti 10% (yakaverengerwa zvichienderana nenhamba) yemapombi esimbi mapfupi ane kureba kwe2-4m anobvumirwa pabatch. 4m ndiwo muganho wakaderera wehurefu husingaverengeki, uye hurefu hupfupi hunobvumidzwa i2m.
