Izinto ze-Metallic lapho amandla angaphandle edlula umkhawulo wesivuno, azokhiqiza ukuguquguquka kwepulasitiki unomphela, okuwumgomo oyisisekelo weukugoba kwe-tube.Ukugoba ishubhu, udonga lwangaphandle ngenxa yokwelula nokuncipha kwalo kokucindezelwa okuphakathi ngenxa yokuqina, njengoba umphumela wokunwebeka nokucindezelwa, futhi inqubo yokugoba, i-tube cross-section ishintshile, ushintsho kusiyingi singena endaweni. umkhuba we-ellipse.

Indlela yokugoba i-tube ihlukaniswe yaba izinhlobo ezimbili zokugoba nokugoba okubandayo, amakhaza asezingeni lokushisa elilingana nomshini wokugoba indololwane, ukugoba okumuncele ingxenye egobile yeshubhu ishisiswe ekushiseni okuthile, bese kuba ngumshini (umshini wepayipi ogobayo) noma indololwane ngesandla.Insimbi eyakhiwe ngokubandayo ayibhubhisi imvelo yasekuqaleni, ayikhiqizi ukuguquka kokushisa.Kodwa izindololwane ezakheke ngokubanda zidinga ukusebenzisa amandla engeziwe, futhi ingcindezi ephindiselayo kanye nensalela inokwenyuka okubaluleke kakhulu, kodwa hhayi i-radius egobile yokugoba kwamakhanda okujika abukhali awakheke ngokubanda.Ukuyigoba ngeke kuqhathaniswe nokuvumelana nezimo ezibandayo.

Ukugoba nokushisela ngokuhambisana ne-oda, inqubo yokugoba ingabuye ihlukaniswe ngokuthi "ukugoba kokuqala nokushisela" kanye "ngemuva kokugoba kwe-weld yokuqala" ezinqubweni ezimbili ezihlukene zokugoba.Okubizwa ngokuthi "ukugoba nokushisela kokuqala," kusekelwe kumingcele ehlukahlukene yepayipi yepayipi noma umdwebo wezingxenye ezinjengezinduku ezihlinzekiwe, ukugoba kwe-tube yokuqala.Futhi-ke endaweni yesikhulumi ye-SAMS noma ye-SAMS yokubeka izesekeli zokuxhuma i-tube flange, umsebenzi wokushisela.Nquma ubude bepayipi eliqondile lokusika izingxenye zemishini ngokusho komdwebo noma isampula yezinduku zeshubhu, iphutha lapho ucabangela indololwane, ukusika ubude benqubo yokubeka isibonelelo esijwayelekile.“I-weld bend yokuqala” isekelwe kubude beshubhu dweba usayizi wepayipi lomugqa inani eliphumayo lekhompyutha lomdwebo wezingxenye, isikulufu se-angle flange esihlobene K, i-angle yesikulufu se-flange nohlelo lwe-NC kanye nochungechunge lwedatha yokucubungula, usebenzisa i-no. imajini ngaphansi kwempahla, okokuqala emsamo noma umshini we-SAMS obekwe ama-flange amapayipi aqondile, ukushisela, bese kuba umsebenzi wokugoba.
