Iimfuno zobuchwephesha kwimibhobho edityanisiweyo ethe tye: Iimfuno zobugcisa kunye nokuhlolwa kwemibhobho edityanisiweyo ethe tye isekelwe kumgangatho we-GB3092 "welded Steel Pipes for Low-Pressure Fluid Fluid Transport". Ububanzi obuqhelekileyo bombhobho odibeneyo ngu-6 ~ 150mm, ubukhulu bodonga oluyi-2.0 ~ 6.0mm, kunye nobude bombhobho odibeneyo Ngokuqhelekileyo i-4 ~ 10 yeemitha, inokuthunyelwa ukusuka kumzi-mveliso ubude obusisigxina okanye ubude obuninzi. Umphezulu wombhobho wensimbi kufuneka ugudiswe, kwaye iziphene ezinjengokusonga, ukuqhekeka, i-delamination, kunye ne-lap welding ayivumelekanga. Umphezulu wombhobho wensimbi uvumelekile ukuba ube neziphene ezincinci ezifana nokukrazula, ukukrazula, ukuchithwa kwe-weld, ukutshisa, kunye nezibazi ezingagqithisi ukuphambuka okungalunganga kodonga lodonga. Ukuqina kodonga lwe-weld kunye nobukho bemivalo ye-weld yangaphakathi ivumelekile. Imibhobho yentsimbi edityanisiweyo kufuneka ihlole ukusebenza ngoomatshini, iimvavanyo zokuthambisa, kunye novavanyo lokwandisa, kwaye kufuneka ihlangabezane neemfuno ezibalulwe kumgangatho. Umbhobho wensimbi kufuneka ukwazi ukumelana noxinzelelo lwangaphakathi lwe-2.5Mpa kwaye ugcine ukungabikho ukuvuza ngomzuzu omnye. Kuvunyelwe ukusebenzisa indlela ye-eddy yangoku yokufumanisa impazamo endaweni yovavanyo lwe-hydrostatic. Ukufunyaniswa kwesiphene kwangoku kwe-Eddy kuqhutywa ngumgangatho we-GB7735 "Indlela yokuHlola i-Eddy yangoku ye-Flaw yeMibhobho yentsimbi". Indlela yokufumanisa impazamo yangoku kukulungisa i-probe kwisakhelo, gcina umgama we-3 ~ 5mm phakathi kokubona impazamo kunye ne-weld, kwaye uthembele ekuhambeni ngokukhawuleza kombhobho wensimbi ukuqhuba ukuskena okubanzi kwe-weld. Isignali yokufumanisa impazamo icutshungulwa ngokuzenzekelayo kwaye ihlelwe ngokuzenzekelayo yi-eddy yangoku ye-flaw detector. Ukufezekisa injongo yokufumanisa isiphene. Emva kokubona impazamo, umbhobho odityanisiweyo unqunyulwa ubude obuchaziweyo ngesarha ephaphazelayo kwaye uqengqiwe ngaphandle komgca wokuvelisa ngeflip frame. Zombini iziphelo zombhobho wentsimbi kufuneka zibe tyaba-chamfere kwaye ziphawulwe, kwaye imibhobho egqityiweyo kufuneka ifakwe kwimiqulu engama-hexagonal ngaphambi kokushiya umzi-mveliso.

Indlela yokulungisa umbhobho wentsimbi yomthungo othe tye: Umbhobho wentsimbi womthungo othe tye ngumbhobho wentsimbi onomthungo we-weld ongqamene nolwalathiso lwelongitudinal lombhobho wentsimbi. Amandla ombhobho wentsimbi ngokuqhelekileyo aphezulu kunombhobho odityanisiweyo othe tye. Ingasebenzisa iibhilidi ezincinci ukuvelisa imibhobho edityanisiweyo enkulu, kwaye ingasebenzisa iibhilidi ezinobubanzi obufanayo ukuvelisa iidamitha zemibhobho. Imibhobho edityanisiweyo eyahlukeneyo. Nangona kunjalo, xa kuthelekiswa nemibhobho eqondileyo yobude obufanayo, ubude be-weld bunyuswe nge-30 ~ 100%, kwaye isantya sokuvelisa siphantsi. Ngoko ke zithini iindlela zayo zokusetyenzwa?

1. Intsimbi yokubumba: Indlela yokucutshungulwa koxinzelelo esebenzisa impembelelo yokubuyisela isando sokubumba okanye ukunyanzeliswa komshicileli ukutshintsha into engenanto ibe yimo kunye nobukhulu esiyifunayo.
2. I-Extrusion: Yindlela yokucubungula insimbi apho isinyithi sifakwe kwi-cylinder evaliweyo ye-extrusion kwaye uxinzelelo lufakwe kwelinye icala ukuze lukhuphe isinyithi ukusuka kumngxuma wokufa omiselweyo ukufumana umkhiqizo ogqityiweyo wesimo esifanayo kunye nobukhulu. Isetyenziselwa kakhulu ukuveliswa kweentsimbi ezingenayo i-ferrous. Izinto zentsimbi.
3. Ukuqengqeleka: Indlela yokucutshungulwa koxinzelelo apho intsimbi yentsimbi engenanto idlula kwi-gap (yemilo eyahlukeneyo) phakathi kwee-roller ezijikelezayo. Ngenxa yokunyanzeliswa kwee-roller, icandelo lezinto eziphathekayo liyancitshiswa kwaye ubude bunyuswa.
4. Intsimbi yokudweba: Yindlela yokucubungula eyenza intsimbi edibeneyo (emilo, ityhubhu, imveliso, njl.) ngokusebenzisa umngxuma wokufa ukunciphisa i-cross-section kunye nokwandisa ubude. Uninzi lwazo lusetyenziselwa ukucubungula okubandayo.
