Kukho iishedyuli ezahlukeneyo kule mibhobho njengoko ibamba amanqanaba ahlukeneyo oxinzelelo.Ngokuqhelekileyo kukho i-sch 80, 100, 120, 140 kunye ne-160 eneendonga ezinzima.Umbhobho obunzima bodonga olungenamthungo ngamanye amaxesha unokuphinda ube namandla ngakumbi kwaye uchazwe njenge XXS okanye XXS.Izinto zinokwahluka njengoko kukho amabanga ahlukeneyo entsimbi yekhabhoni ezisetyenziselwa ukwenza iintlobo ezahlukeneyo zemibhobho yentsimbi yodonga lwekhabhoni.Umthamo ophezulu, ukuhamba okuphezulu, iinkqubo zoxinzelelo oluphezulu ezifana nemigca yokuhambisa ioli kunye negesi, imigca yamanzi, kunye neenkqubo zokupholisa zeplanti yamandla zonke ezisetyenzisiweyo iintlobo ezahlukeneyo.
Imibhobho yentsimbi eshinyeneyo engenamthungo isetyenziswa ikakhulu kwindawo yokugcina amanzi, i-petrochemical, ikhemikhali, amandla ombane, ukunkcenkceshela kwezolimo, ukwakhiwa kwedolophu kunye namanye amashishini.Kuthutho lwamanzi: unikezelo lwamanzi kunye nokukhupha amanzi.Ukuthuthwa kwerhasi: irhasi yendalo, umphunga, igesi yepetroleum engamanzi.Ukusetyenziswa kolwakhiwo: isetyenziswa njengebhulorho yokugobela imibhobho;amadokhi, iindlela, izakhiwo kunye nezinye izakhiwo.
Isitshixo kumgangatho wemibhobho yentsimbi enodonga olungqingqwa kufuneka ibe ukufana kobukhulu.Ubukhulu bodonga olungalawulekiyo lwemibhobho yentsimbi enodonga olungqindilili buchaphazela ngokuthe ngqo umgangatho kunye nokusebenza kwemibhobho yentsimbi, imibhobho yentsimbi enodonga olungqingqwa, kunye nemibhobho yentsimbi enomthungo emikhulu enobubanzi.Ngokuqhelekileyo isetyenziselwa ukusetyenzwa okuhlukeneyo kunye nokulungiswa kweengxenye ezishinyeneyo.,, Ubukhulu bodonga obufanayo bombhobho wensimbi buya kuchaphazela ngokuthe ngqo umgangatho wamacandelo asemva kokulungiswa, udonga lombhobho wensimbi ongqingqwa alulawulwa, kwaye umgangatho wentsimbi awungqongqo.
Imibhobho yentsimbi enodonga olungqingqwa ibhekiselele kwimibhobho yentsimbi enobubanzi bombhobho nomlinganiselo wobukhulu bodonga obungaphantsi kwama-20. Isetyenziswa kakhulu kwimibhobho yokomba yepetroleum yejoloji, imibhobho eqhekekileyo yepetrochemical, imibhobho yebhoyila, imibhobho ethwele imibhobho kunye nemibhobho yolwakhiwo oluchanekileyo kakhulu yeemoto, iiteletele uphapho.Umgangatho wemibhobho yentsimbi engenamthungo etyebileyo ixhomekeke ekufanisweni kobukhulu bodonga.
Ityhubhu engqukuva billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhulisa → ukuhluba → ukulinganisa (okanye ukunciphisa ubukhulu) → ukupholisa → ukolula → uvavanyo lolwelo loxinzelelo lwehydraulic (okanye ukubhaqwa kwempazamo) → ukumakisha → ukugcina.
Iimpawu mechanical imibhobho enzima wallthickness isalathiso ebalulekileyo ukuqinisekisa ukusebenza yokugqibela ukusetyenziswa (iipropati mechanical) of enzima wallthickness imibhobho yentsimbi imibhobho yentsimbi, kwaye kuxhomekeke ukwakheka imichiza kunye nenkqubo yonyango ubushushu umbhobho yentsimbi.Ke ngoko, ngokweemfuno ezahlukeneyo zesicelo, iipropathi zoomatshini zemibhobho yentsimbi engqindilili eludongeni yaziswa ngokukodwa ukusuka kwimiba yamandla okuqina, indawo yesivuno, kunye nobude.
1. Amandla okuqina
Kwinkqubo yokuqina, awona mandla aphezulu (Fb) athwalwa yisampulu xa iqhekezwa luxinzelelo (σ) olufunyenwe kwindawo yokuqala enqamlezileyo (Ngoko) yesampulu, ebizwa ngokuba ngamandla okuqina (σb), kunye iyunithi yi-N/mm2 (MPa).Imele amandla aphezulu ezinto zetsimbi ukuxhathisa umonakalo phantsi kwamandla obunzima.
2. Inqaku lesivuno
Kwizinto zetsimbi kunye nesiganeko sokuvunwa, uxinzelelo apho isampuli inokuqhubeka ixesha elide ngaphandle kokunyuka kwamandla ngexesha lenkqubo yokwelula (ihlala ihleli) ibizwa ngokuba yinqanaba lesivuno.Ukuba amandla ehla, amanqaku aphezulu kunye nasezantsi kufuneka ahlulwe.Iyunithi yenqaku lesivuno yi-N/mm2 (MPa).
3. Ubude emva kokuqhekeka
Kuvavanyo lwe-tensile, ipesenteji yobude bobude begeyiji yonyuka emva kokuba isampulu yaphulwe ukuya kubude begeyiji yoqobo ibizwa ngokuba lubude.Ichazwe ngu σ, iyunithi yi%.
