Isishwankathelo soMbhobho weIron weDuctile
Imibhobho ye-Iron ye-Ductile yimibhobho eyenziwe nge-ductile iron. Intsimbi yentsimbi yintsimbi etyhidiweyo yegraphite. Izinga eliphezulu lokuthembeka kwentsimbi ye-ductile ngokuyinhloko ngenxa yamandla ayo aphezulu, ukuqina, kunye nempembelelo kunye nokuxhathisa ukubola. Imibhobho yentsimbi erhuqwayo idla ngokusetyenziselwa ukuhanjiswa kwamanzi aselwayo kunye nokumpompa udaka, ugutyulo kunye neekhemikhali ezilungiswayo. Le mibhobho yentsimbi luphuhliso oluthe ngqo lwemibhobho yentsimbi yangaphambili ephantse yayitshintsha. Inqanaba eliphezulu lokuxhomekeka kwimibhobho yensimbi ye-ductile ngenxa yeempawu zayo ezahlukeneyo eziphezulu. Le mibhobho yeyona mibhobho ifunwa kakhulu kwizicelo ezininzi.

Amabanga amaThathu aPhambili oMbhobho wentsimbi oCaliweyo
I-V-2 (iklasi 40) i-Grey Iron, i-V-3 (65-45-12) i-Ductile Iron, kunye ne-V-4 (80-55-06) i-Ductile Iron. Banika amandla abalaseleyo oxinzelelo kunye nokukwazi ukudambisa ukungcangcazela okuphezulu.
I-V-2 (iklasi 40) i-Grey Iron, i-ASTM B48:
Eli bakala linamandla aphezulu e-40,000 PSI kunye namandla oxinzelelo lwe-150,000 PSI. Ubunzima bayo buvela kwi-187 - 269 BHN. I-V-2 ifaneleka ngokufanelekileyo kwizicelo zokunxiba ezithe ngqo kwaye inamandla aphezulu, ubulukhuni, ukuxhathisa ukunxiba kunye nokuphendula ubushushu kwintsimbi engwevu engafakwanga. Isetyenziswa ngokubanzi ekuthwaleni nasekusebenziseni ibhulorho kwishishini le-hydraulics.
I-V-3 (65-45-12) i-Ductile Iron, i-ASTM A536:
Eli bakala linamandla okuqina kwe-65,000 PSI, amandla esivuno se-45,000 PSI, kunye ne-12% elongation. Ubunzima buvela kwi-131-220 BHN. Ulwakhiwo lwayo oluhle lwe-ferritic lwenza i-V-3 ibe yeyona ndlela ilula yokucoca amabakala amathathu entsimbi iyenza ibe yenye yomgangatho ophezulu wobuchule obulinganiswe kwezinye izixhobo ze-ferrous; ngokukodwa zidibaniswe nempembelelo efanelekileyo, ukukhathala, ukuhanjiswa kombane kunye neempawu zokungena kwamandla kazibuthe. I-Ductile Iron, ngakumbi imibhobho, isetyenziswa ikakhulu kwimibhobho yamanzi neyogutyulo. Le ntsimbi ifumaneka ngokuqhelekileyo kumacandelo eemoto kunye nezicelo zoshishino.
I-V-4 (80-55-06) i-Ductile Iron, i-ASTM A536:
Eli bakala linamandla e-tensile ye-80,000 PSI, amandla esivuno se-55,000 PSI kunye nobude be-6%. Ngowona mandla aphakamileyo kula mabanga mathathu, njengoko kusenziwa. Eli bakala lingaphathwa ubushushu ukuya kwi-100,000 PSI yamandla okuqina. Inomlinganiselo we-10-15% ophantsi we-machiniability kune-V-3 ngenxa yesakhiwo sayo se-pearlitic. Idlalwa kakhulu xa kufuneka i-steel physicals.
Imibhobho ye-DI ingcono kunemibhobho yentsimbi / yePVC / HDPE
• Imibhobho ye-DI ikwasindisa iindleko zokusebenza ngeendlela ezininzi eziquka iindleko zokumpompa, iindleko zokucofa, kunye nomonakalo onokwenzeka kolunye ulwakhiwo, okubangela ukusilela kunye neendleko zokuyilungisa ngokubanzi.
• Iindleko ze-Lifecycle ze-DI Pipes yenye yeenzuzo zayo ezinkulu. Ekubeni ihlala kwizizukulwana, inoqoqosho ukuba isebenze, kwaye ngokulula nangokufanelekileyo ifakwe kwaye iqhutywe, iindleko zayo zexesha elide okanye ze-lifecycle ziphantsi ngokulula kunezinye izinto.
• Umbhobho wentsimbi odityanisiweyo ngokwawo yi-100% yemathiriyeli enokuphinda isetyenziswe.
• Yomelele ngokwaneleyo ukumelana neemeko ezinzima kakhulu, ukusuka kwizicelo zoxinzelelo oluphezulu, emhlabeni onzima kunye nemithwalo yezithuthi, ukuya kwiimeko ezingazinzanga zomhlaba.
• Ukufakela kulula kwaye kukhuselekile kubasebenzi abanokusika nokucofa iDuctile Iron Pipe kwisiza.
• Ubume benkcenkce boMbhobho we-Iron weNsimbi buthetha ukuba umbhobho unokubekwa lula phantsi komhlaba kunye neendawo zokukhangela imibhobho eqhelekileyo.
•Imibhobho ye-DI inika amandla aphezulu okubamba kunentsimbi ethambileyo kwaye igcina uxhathiso lwendalo lwentsimbi.
