Umbhobho odityanisiweyo, owaziwa ngokuba ngumbhobho wentsimbi odityanisiweyo, wenziwe ngepleyiti yentsimbi okanye umcu odityaniswe emva kokubola kunye nokwenza.Umbhobho wensimbi odityanisiweyo uneenzuzo zenkqubo yokuvelisa elula, ukusebenza kakuhle kwemveliso, iintlobo ezininzi kunye neenkcukacha, kunye notyalo-mali oluncinci lwezixhobo, kodwa amandla ayo ngokubanzi angaphantsi kunombhobho wensimbi ongenamthungo.Ukusukela ngeminyaka yoo-1930s, ngophuhliso olukhawulezayo lomgangatho ophezulu wemveliso yokuqengqeleka kunye nenkqubela phambili yetekhnoloji yokuwelda kunye nokuhlola itekhnoloji, umgangatho we-welded seam uye waphuculwa ngokuqhubekayo, iindidi kunye neenkcukacha zombhobho wentsimbi odityanisiweyo uye wanda, kunye nentsimbi engenamthungo. umbhobho utshintshwe kwiindawo ezininzi nangaphezulu.Imibhobho yentsimbi edityanisiweyo yahlulwe yaba ngumbhobho odityanisiweyo othe tye kunye nombhobho odityanisiweyo we-spiral ngokohlobo lwe-weld.

一.Ulwahlulo lweMibhobho e-Welded Iityhubhu ezidityanisiweyo

Imibhobho edityanisiweyo ihlelwa ngokwendlela ezisetyenziswa ngayo: ikwahlelwa ngokwemibhobho edityanisiweyo ngokubanzi, imibhobho edityanisiweyo, imibhobho edityanisiweyo yeoksijini, imibhobho edityanisiweyo, imibhobho yocingo, imibhobho edityanisiweyo yemetric, imibhobho edityanisiweyo, imibhobho yempompo enzulu, imibhobho yemoto, imibhobho yesiguquli, imibhobho edityanisiweyo. imibhobho edityanisiweyo, imibhobho edityanisiweyo engaqhelekanga kunye nemibhobho edityanisiweyo.

二.Uluhlu lweSicelo seMbhobho eWelded

Iimveliso zemibhobho edityanisiweyo zisetyenziswa kakhulu kwibhoyila, kwinqwelo-mafutha, kwisakhiwo seenqanawa, kwisakhiwo seengcango zobunzima obulula kunye neefestile zentsimbi, ifenitshala, oomatshini bezolimo abahlukeneyo, isikhafu, umbhobho wokuthunga intambo, iishelfu eziphezulu, izikhongozeli njalo njalo ezi zinto. inokuhlangabezana neemfuno zomthengi, umbhobho odityanisiweyo okhethekileyo ongaqhelekanga unokuveliswa ngokweemfuno zomsebenzisi.

三.INDLELA YOKUBALA NGOKUCINGA KOMbhobho OWELDIWEYO  

Kukho iifomula zokubala ubunzima bombhobho odibeneyo.

Ubunzima bethiyori ngemitha yombhobho wentsimbi (ubuninzi bentsimbi yi-7.85 kg / dm3)

Ifomula: W = 0.02466 (DS)S

Kwifomula yokubala, ubunzima bethiyori ye-W-steel pipe ngemitha, kg / m;

D - Ububanzi obuqhelekileyo bombhobho wensimbi, mm;

S - ubukhulu bodonga oluqhelekileyo lombhobho wensimbi, mm.

四.Inkcazo esemthethweni kunye nokuSetyenziswa kweShishini loMbhobho oDidiweyo

Izinto ezisetyenziswayo kwi-welded tube mill yintsimbi yentsimbi okanye umcu wentsimbi.Inokwahlulwa ibe ngumbhobho odityanisiweyo wesithando somlilo, umbhobho odityanisiweyo wombane kunye nombhobho odityanisiweyo we-arc ozenzekelayo ngenxa yetekhnoloji ye-welding eyahlukeneyo.Ngokweendlela ezahlukeneyo ze-welding, inokwahlulwa ibe ngumbhobho odityanisiweyo othe tye kunye ne-spiral welded pipe.per kwimilo yesiphelo, inokwahlulwa ibe ngumbhobho odityanisiweyo ojikelezileyo kunye nombhobho odityanisiweyo okhethekileyo (umbhobho wesikwere osicaba njl.) .Imibhobho edityanisiweyo inokwahlulwa ngokwezi ndidi zilandelayo ngokwezixhobo zabo ezahlukeneyo kunye nokusetyenziswa:
