Kwintsimi yeimibhobho yentsimbi, imigangatho ye-arc edityanisiweyo yentsimbi yomthungo imibhobho ibalulekile.Omnye wemigangatho yi-GB/T3091-2008, equka iintlobo ezahlukeneyo zemibhobho yentsimbi yomthungo ethe tye, efana nokumelana nokuphakama okuphezulu.imibhobho yentsimbi edityanisiweyo (ERW)., i-arc emanziwelded (SAWL) imibhobho yentsimbikunye nemibhobho yentsimbi edityanisiweyo ye-arc edityanisiweyo (i-SAWH).)Umbhobho wentsimbi.
Ukuthuthwa koxinzelelo oluphantsi, i-GB/T3091-2008 ikwachaza ukusetyenziswaimibhobho yentsimbi edityanisiweyo.Le mibhobho yentsimbi edityanisiweyo yombane, eyaziwa njengemibhobho emhlophe, isetyenziselwa ukuthutha amanzi, igesi, umoya, ioyile, umphunga wokufudumeza, amanzi ashushu, njl. ubukhulu bathobele imimiselo GB/T21835.Ngaphezu koko, ubude bombhobho wensimbi bunokuvela kwi-300mm ukuya kwi-1200mm, kwaye inokulungiswa ubude okanye ubude obuphindwe kabini.
Xa kuziwa kwimiba esemgangathweni, ubushushu ngexesha lenkqubo yokubhoboza kunempembelelo enkulu.Imibhobho yentsimbi yokwandiswa kwe-Thermal ifikelela kumaqondo obushushu ajikeleze i-1200 ° C, nangona umxholo wekhabhoni kunye nezinto ezixutywayo zinokunciphisa amaqondo obushushu kancinci.Omnye umba ophambili omawuqwalaselwe kukunciphisa ubungakanani besikali ngexesha lokugoba okushushu, njengoko oku kunokuchaphazela ubomi besixhobo kunye nomgangatho womphezulu.
Umsebenzi wokufudumeza yinkqubo ebalulekileyo kwimveliso ye16Mn umbhobho wentsimbi yomthungo othe tye.Kuba uninzi lokusetyenzwa lwenzeka kwindawo eshushu, ulawulo oluchanekileyo lobushushu bobushushu lubalulekile ukuqinisekisa umgangatho wemveliso yokugqibela.
Ukugcina umgangatho kunye nemigangatho, ukulawula ubushushu ngexesha lokubhoboza kubalulekile.Umbhobho wentsimbi yomthungo othe tye umgangatho we-GB/T3091-2008 ucacisa ukutenxa okuvumelekileyo kubungakanani, imilo, ubunzima kunye nobukhulu bangaphandle kunye nobukhulu bodonga.Ukutenxa okuvumelekileyo komgangatho wodonga olusemgangathweni kuyahluka ngokwebakala lokutenxa, ukusuka kwi-S1 ukuya kwi-S5, kwaye ibakala ngalinye lichaza ipesenti ehambelanayo kunye nokutenxa okuncinci.
Ukongeza kokunyamezelwa kobunzima bodonga olusemgangathweni, ukunyamezelwa kobunzima bodonga obungalinganiyo kuyaqwalaselwa.Amanqanaba okutenxa (umzekelo, i-NS1 ukuya ku-NS4) abandakanya ukutenxa kwipesenti ethile ukuqinisekisa ulawulo lomgangatho.Kufuneka kuqatshelwe ukuba i-S imele ubukhulu bodonga olubizwa ngokuba ngumbhobho wensimbi, kwaye i-D imele i-dimeter yangaphandle ye-opharetha yensimbi.
Ukuqinisekisa ukuthotyelwa kwale migangatho kubaluleke kakhulu kwimveliso yomgangatho ophezulu we-arc we-arc we-welded steel pimples.Ngokugcina ulawulo oluchanekileyo lobushushu kunye nokunikela ingqalelo ekuphambukeni okuvumelekileyo, abavelisi banokuhlangabezana nokulindelwe ngabathengi kwaye babonelele ngeemveliso ezithembekileyo nezizinzileyo.
