Amagqabantshintshi omdaka wentsimbi ye-ductile
Imibhobho yentsimbi ye-ductile yimibhobho eyenziwe ngentsimbi ye-ductile. Intsimbi ye-ductile yigrafu yegrafikhi ephosakeleyo. Inqanaba eliphezulu lokuxhomekeka kwentsimbi ye-ductile ngokuyintloko ngenxa yamandla alo aphakamileyo, ukuqina, kunye nefuthe kunye nokunganyangeki. Imibhobho yentsimbi ye-ductile idla ngokusetyenziswa kokusasazwa kwamanzi okuyingwa kunye nokumpompa, ukuntywila kunye neekhemikhali zekhemikhali. Imibhobho yentsimbi iphuhliswa ngokuthe ngqo kwemibhobho yentsimbi eyandulelayo ngoku ephantse yathatha indawo. Inqanaba eliphezulu lokuxhomekeka kwimibhobho yentsimbi yentsimbi kungenxa yepropathi yayo eyahlukeneyo. Le mibhobho yeyona ifunwayo emva kwemibhobho kwizicelo ezininzi.

Amanqanaba amathathu aphambili ombhobho wensimbi ebhalwe
V-2 (iklasi 40) Intsimbi ye-Grey, v-3 (65- 4- 4- 4- 4)) Intsimbi yentsimbi, kunye ne-V-4 (80-55) intsimbi ye-ductile. Banikezela ngamandla apheleleyo oxinzelelo kunye nesakhono esiphezulu sokuhambisa umvuzo.
V-2 (iklasi 40) intsimbi ye-Grey, i-ASTM B48:
Eli nqanaba linamandla aphezulu angamanye ama-40,000 psi ngokunyanzelwa kwe-150,000 ye-PSI. Ubunzima bayo bususela ngo-187 - 269 Bhn. I-V-2 ilungele ukusetyenziswa ngokuthe tye kwaye inamandla aphezulu, ubukhali, ukumelana nokunxiba kunye nobushushu banyanga impendulo yentsimbi engwevu engathandwayo. Isetyenziselwa ngokubanzi ukukhupha kunye nokusetyenziswa kwe-tyhudi kwishishini le-hydraulics.
V-3 (65- 44)
Eli nqanaba linamandla e-thensile angama-65,000 psi, ukuvelisa amandla angama-45,000 eeNdu, ene-12% ye-12%. Ubunzima buba ngamaqhinga ukusuka kwi-131-20 Bhn. Isakhiwo sayo esihle se-Ferrictic senza i-V-3 ilula yoomatshini olula kumabakala amathathu amabakala awenze ukuba abe nolunye lonxibelelwano oluphakamileyo zezinye izinto ezinzima; Idityaniswe ngqo nefuthe eliphezulu, ukudinwa, ukuqhubela phambili kombane kunye neepropathi zobungqina bemagnethi. I-ductile yentsimbi, ngakumbi imibhobho, ngokuyintloko isetyenziselwa imigca yamanzi kunye ne-wibage. Esi sinyithi sikwisiqhelo sifumaneka kwizinto ezizenzekelayo nakwizicelo zemveliso.
V-4 (80-55) Intsimbi ye-ductile, i-Astm A536:
Eli nqanaba linabanamandla angama-80,000 psi, ukuvelisa i-55,000 ye-PSI kunye ne-elongiya ye-6%. Ngamandla aphezulu kumabakala amathathu, njengoko kuphoswa. Eli nqanaba linokuba ngumtshijoli ukuba linyangwe kangange-100 000 lamandla e-PSI. Inomgangatho we-10-16% ye-scocniniailiailiaimailiaimailiaimailiaimailiaimailiaimainiam kune-V-3 ngenxa yesakhiwo sayo se-Pearlicac. Ihlala ikhethwe xa imizimba yentsimbi iyafuneka.
Imibhobho ye-D ibhetele kunentsimbi / i-pvc / pipes ye-HDPE
Imibhobho ye-IND ikwandisa iindleko zomsebenzi ngeendlela ezininzi kubandakanya iindleko zokupeyinta, iindleko, kunye nomonakalo onokwenzeka obakho kwakhiwa, ukusilela ukulungisa ngokubanzi.
Iindleko zempilo yobomi zenye yezona zibonelelo zibalaseleyo. Kuba ihleli kwizizukulwana, inoqoqosho isebenza, kwaye ifakwe ngokulula kwaye isebenza ngokufanelekileyo kwaye isebenza ngokufanelekileyo, isebenza ngokufanelekileyo, iindleko zayo zexesha elide okanye indleko zexesha elide ziphantsi kunezinye izinto.
• Umbhobho wentsimbi ye-ductile ngokwayo yi-100% yezinto ezinokuphinda zisebenzise.
• Yomelele ngokwaneleyo ukumelana neemeko eziqatha, ukusuka kwizicelo zoxinzelelo oluphezulu, ukuya kuMhlaba onzima kunye nemithwalo yezithuthi, kwiimeko zomhlaba ezingazinzanga.
• Ufakelo lulula kwaye lukhuselekile kubasebenzi abanokusika kunye nokucofa umbhobho wentsimbi ye-ductile kwisiza.
• Uhlobo lwensimbi yombhobho wentsimbi ye-ductile uthetha ukuba umbhobho unokufumaneka ngokulula phantsi komhlaba kunye neendawo eziqhelekileyo zombhobho.
•Imibhobho ye-D inika amandla amanye amanye amanye kunentsimbi ethobekileyo kwaye igcine ukunganyangeki kwendalo yentsimbi.
