Umbhobho ojikelezayo (SSAW)umzi-mveliso uncamathela ukubaluleka okukhulu ekulahlekeni kombhobho ojikelezayo. Ukususela kwintsimbi yentsimbi ukuya kwisantya semveliso egqityiweyo yombhobho ojikelezayo, izinga lokulahleka komenzi wepayipi ye-spiral ngexesha le-welding lichaphazela ngokuthe ngqo ixabiso leendleko zombhobho ojikelezayo.

Ifomula yokubala isivuno sombhobho ojikelezayo:
b=Q/G*100

b lixabiso lemveliso egqityiweyo, %; Q bubunzima beemveliso ezifanelekileyo, ngeetoni; U-G bubunzima bemathiriyeli ekrwada kwiitoni.

Isivuno sinobudlelwane obulinganayo kunye ne-coefficient yokusetyenziswa kwentsimbi K.

b=(GW)/G*100=1/K

Into ephambili echaphazela ukuveliswa kwezinto yilahleko eyahlukeneyo yesinyithi eyenziwa ngexesha lenkqubo yokuvelisa. Ngoko ke, indlela yokuphucula imveliso yezinto eziphathekayo ikakhulu ukunciphisa ilahleko ezahlukeneyo zetsimbi.

Ekubeni izinto ezisetyenziswayo kwi-workshop yentsimbi nganye zihluke kwiimveliso ezigqityiweyo, umzekelo, ezinye ii-workshops zensimbi zisebenzisa i-ingots zetsimbi njengezinto ezibonakalayo, ezivulekileyo ezivulekileyo phakathi, kwaye ziqhube kwizinto eziphathekayo; ezinye iiworkshops zisebenzisa ngokuthe ngqo iingots zentsimbi njengezinto ezikrwada kwaye ziqengqeleke zibe yimathiriyeli; Iibhilithi zetsimbi zisetyenziswa njengezinto eziluhlaza ukuqengqeleka kwizinto; kukwakho nezinye iindibano zocweyo ezisebenzisa intsimbi njengezinto ezikrwada ukusetyenzwa kweemveliso ezahlukeneyo zentsimbi ezigqityiweyo. Ngoko ke, kunzima ukusebenzisa indlela yokubala isivuno ukuvakalisa kunye nokuthelekisa imeko yokuvuna isinyithi kwinkqubo yokuvelisa, kwaye kunzima ukubonakalisa ukungafani kwinqanaba leteknoloji yokuvelisa kunye nenqanaba lolawulo lweworkshop. I-HSCO spiral pipe factory yathi kukho iindlela ezahlukeneyo zokubala isivuno, ezifana nemveliso yeengots zentsimbi, imveliso yeengots zentsimbi, kunye nemveliso yeebhilidi zangaphandle. Ivenkile eqengqelekayo nganye kufuneka ibalwe ngokwemeko ethile.

Umbhobho ojikelezayo ubalo lolahleko:

Izinga lelahleko yokwenziwa kombhobho we-Spiral libhekisa kumlinganiselo wenkunkuma wezinto ezikrwada kwinkqubo yokwenziwa kombhobho ojikelezayo. Ngokohlalutyo lweenkcukacha-manani lwabasebenzi abaqeqeshiweyo kunye nobugcisa iminyaka emininzi, izinga lelahleko yokwenziwa kwemibhobho ejikelezayo iphakathi kwe-2% kunye ne-3%.
phakathi. Kwinkqubo yokuvelisa i-spiral tube, amacandelo aphambili enkunkuma ngala: inxalenye engaphambili ye-spiral tube eyenza, umsila, i-milling edge ye-raw material, kunye namanyathelo ayimfuneko kwinkqubo yokuvelisa i-spiral tube. Ukuba umbhobho ojikelezayo awukwazi ukuxutywa kunye nomsila ngokwemigangatho eqhelekileyo ngexesha lenkqubo yokuvelisa, umbhobho wentsimbi oveliswayo unomlinganiselo ophantsi kakhulu wegridi.

Indlela yokulawula izinga lokulahleka kombhobho ojikelezayo?
1. Emva kokuba ipayipi yensimbi ye-spiral yenziwe, kuyimfuneko ukusika isiqwenga sokuqala kwaye ususe umsila ukukhusela ukungahambi kakuhle kombhobho wensimbi. Le yinkqubo ebalulekileyo yokuqinisekisa ukucaciswa kunye nokubonakala kwemibhobho yensimbi, kwaye inkunkuma iya kuveliswa ngeli xesha.

2. Ukusetyenzwa kwemathiriyeli ekrwada, intsimbi yomtya kufuneka igalelwe kunye nolunye unyango phambi kokuba i-welding. Kule nkqubo, imathiriyeli yenkunkuma nayo iya kuveliswa.
