Ipayipi lensimbi le-centrifugally cast ductile iron lenziwe nge-spherical graphite cast iron by centrifugal spinning process.Amapayipi, angadlulisa izinto eziningi eziwuketshezi njengamanzi, uwoyela negesi, asetshenziswa kabanzi kumaphrojekthi ahlukahlukene wamapayipi okusansimbi, imayini, ukongiwa kwamanzi, uphethiloli. kanye nezinsiza zomphakathi zasemadolobheni.
1.Ukuba namandla aphezulu, ukuqina okuhle njengensimbi nokumelana nokugqwala okungcono kunensimbi, okungabasiza bamelane nokushaqeka abahlangabezane nakho ngesikhathi sokuthutha, ukufakwa, ukuphatha nokusebenzisa.
2.Ipayipi lensimbi elidonsa amanzi liyindawo ekahle yepayipi lensimbi elimpunga kanye nepayipi elivamile lensimbi.
3.Amapayipi e-DI akhiqizwa ngendlela eqondile eqondile, ngisho nokujiya kodonga, ukunemba kobukhulu obuphezulu, ukuqedwa okushelelayo kwendawo kanye nezakhiwo eziphawulekayo zokukhanda, kanye nongqimba olunamathelayo lwangaphakathi nolwangaphandle.
4.I-Flexible Push-in joint and rubber gasket isetshenziswa okuholela ekufakweni okukahle kwamapayipi.
5.Ziyisinqumo esimeme kakhudlwana, njengoba ngokuvamile enziwa ngezinto ezigaywe kabusha, okuyisici esigqamisayo ngokombono wemvelo.
I-6.I-diameter yangaphakathi inkulu kuneningi, ukugeleza okwandayo, okunciphisa ukusetshenziswa kwamandla kanye nezindleko zokupompa ngokuhamba kwesikhathi
I-7.Banamandla okuqhuma okuphezulu, okulungele izicelo zokucindezela okuphezulu.
