1. Umbhobho wentsimbi ongenamthungo ngumcu omde wentsimbi ongenazithungo eziwujikelezileyo kwaye unombhobho onqamlezileyo. Isetyenziswa ngokubanzi njengombhobho wentsimbi yokuthutha ulwelo. Xa kuthelekiswa nentsimbi eqinileyo, ilula ngobunzima xa ukugoba kunye namandla e-torsion afanayo. Intsimbi enqamlezileyo eyongayo esetyenziswa kakhulu ekwenziweni kwezakhiwo kunye nezahlulo zoomatshini, ezifana neeshafti zokuqhuba iimoto, imibhobho yokomba ioyile, iifreyimu zebhayisekile, kunye nesikafula sentsimbi esisetyenziswa ekwakheni.

2. Umbhobho wensimbi odibeneyo ngumbhobho wensimbi owenziwe nge-welding steel plates okanye i-strips strips emva kokuba igobile kwaye yenziwe. Inkqubo yokuvelisa imibhobho yentsimbi edityanisiweyo ilula, ineentlobo ezininzi kunye neenkcukacha, utyalo-mali oluncinci lwezixhobo, kunye nokusebenza kakuhle kwemveliso, kodwa amandla ayo ngokubanzi angaphantsi kunemibhobho yensimbi engenamthungo. Ngophuhliso olukhawulezayo lwemveliso eqhubekayo yokuqengqeleka yentsimbi ekumgangatho ophezulu kunye nokuqhubela phambili kwetekhnoloji yokuwelda kunye nokuhlola, umgangatho we-welds uyaqhubeka uphucuka, iintlobo kunye neenkcukacha zemibhobho yentsimbi edityanisiweyo ziyanda imihla ngemihla, kwaye zithathe indawo engenamthungo. imibhobho yentsimbi kwiindawo ezininzi nangakumbi. Imibhobho yentsimbi edityanisiweyo yahlulwe yaba yimibhobho yentsimbi ejikelezileyo kunye nemibhobho yentsimbi edityanisiweyo ethe ngqo ngokwendlela yentsimbi. ​

Inkqubo yokuvelisa i-straight seam welded steel pipe ilula, ixabiso eliphantsi, uphuhliso olukhawulezayo, kunye nokusebenza kakuhle kwemveliso. Ukomelela kwemibhobho yentsimbi edityanisiweyo iphezulu ngokubanzi kunomthungo othe ngqo wemibhobho yentsimbi edityanisiweyo. Iibhobho zetsimbi ezidibeneyo ezinobubanzi obukhulu zinokuveliswa kwiibhilithi ezincinci, kwaye iibhobho zetsimbi ezidibeneyo ezinobubanzi obuhlukeneyo nazo zinokuveliswa kwiibhilithi zobubanzi obufanayo. Nangona kunjalo, xa kuthelekiswa nemibhobho yentsimbi yomthungo yobude obufanayo, ubude be-weld bunyuswe ngama-30 ~ 100%, kwaye isantya sokuvelisa siphantsi. Ke ngoko, imibhobho yentsimbi edityanisiweyo encinci ubukhulu becala isebenzisa ukuwelda komthungo othe tye, ngelixa imibhobho yentsimbi edityanisiweyo enkulu isebenzisa ubukhulu becala i-spiral welding.
