I-butt-welding flange yenye ye-flanges, ebhekisela kwi-flange enentamo kunye ne-round pipe transition kwaye idibaniswe nombhobho ngokudibanisa i-butt. Ngenxa yokuba ubude bentamo bunokwahlulwaintamo butt welding flangekwayeintamo flat welding flange.
I-butt-welding flanges isetyenziswa ngokubanzi ngenxa yokuba akukho lula ukuyikhubaza, itywinwe kakuhle, isetyenziswa ngokubanzi, ineemfuno ezihambelanayo zokuqina kunye ne-elasticity kunye nengqiqo ye-welding ye-welding thinning transition.
Ngophuhliso lolwakhiwo lwemibhobho emide, i-butt-welded flange ibe yinxalenye ebalulekileyo yovavanyo loxinzelelo lombhobho. Ngaphambi nangemva kovavanyo loxinzelelo, icandelo ngalinye lombhobho kufuneka litshayelwe ngebhola, ngokuphindaphindiweyo ngamaxesha angama-4-5. Ngokukodwa emva kovavanyo loxinzelelo, kunzima ukucoca amanzi kwipayipi, kwaye amaxesha okucoca aya kwanda.
I-flat welding flange yolunye uhloboiflange. Isetyenziswa kakhulu kwaye ikhuthazwa kwishishini loomatshini, kwaye ifumene indumiso kunye nenkoliseko kubasebenzisi abaninzi.
Indawo yokusetyenziswa kwe-flange ye-flange ye-welding ifanelekile, kwaye ixabiso elithile lokusetyenziswa kunye nokusebenza kwe-flange ye-welding flange kufuneka imiselwe ngokwemeko ethile. Imveliso yeFlange ilula kwaye iphantsi kweendleko, kodwa umsebenzi we-welding mkhulu, ukusetyenziswa kwe-electrode kukhulu, kwaye ayikwazi ukumelana nobushushu obuphezulu, uxinzelelo oluphezulu, ukugoba ngokuphindaphindiweyo kunye nokuguquguquka kweqondo lokushisa. Ngokuqhelekileyo isetyenziselwa imibhobho ene-PN ≤ 2.5MPa, ubushushu obuqhelekileyo, kunye nobushushu obusebenzayo t ≤ 0 ℃.
Enye i-weld i-weld yangaphandle phakathi kwe-flange kunye nombhobho, kunye nokuthungatha umbhobho ofakwe kwi-flange. Umbhobho kunye nobuso be-flange buya kuxutywa ngokweemfuno zendibano yomzobo. Qaphela ukuba ubuso be-flange abukwazi ukonakala ngexesha le-welding, ngaphandle koko ukutywinwa akulungile. Indlela ye-welding yi-arc welding manual, kwaye i-welding efunwa yinkqubo ye-welding ingasetyenziswa.
Inzuzo
I-butt-welding flange inesakhiwo esinengqiqo, amandla aphezulu kunye nokuqina, inokumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu, ukugoba ngokuphindaphindiweyo kunye nokuguquguquka kweqondo lokushisa, ukusebenza kakuhle kokutywinwa, kwaye akukho lula ukukhubaza. Isebenza ngokubanzi kwimibhobho enoxinzelelo olukhulu okanye ukuguquka kweqondo lokushisa okanye ukushisa okuphezulu, uxinzelelo oluphezulu kunye nemibhobho yokushisa ephantsi. Kwiintsapho, ububanzi bombhobho buncinci, kwaye luxinzelelo oluphantsi, kwaye ukudibanisa kwe-flange ye-welding flange kungabonakali. Kwigumbi lebhoyila okanye indawo yokuvelisa, kukho imibhobho kunye nezixhobo ezidityaniswe ngeeflange ze-butt welding kuyo yonke indawo.
Ithini indlela yokusetyenzwa kwe-butt welding flange?
1. Ukubumba indawo engenanto kwi-square billet, emva koko ukugoba okubandayo kwicandelo le-arc, i-annealing emva kokunyangwa kobushushu, kwaye emva koko ihlanganiselwe kwisangqa esipheleleyo kwi-lathe ethe nkqo ukuya kwimilo eyilelwe kunye nobukhulu;
2. Isinyathelo sokuqala kukuthutha ukuya kwindawo yokwakha, kwaye emva koko uhlanganise kwaye udibanise amacandelo amaninzi e-arc kwiiflange ezipheleleyo ze-butt welding;
3. I-butt-welding flanges inemigangatho eyahlukeneyo yokuvelisa ekusetyenzisweni nasekuveliseni, kwaye inokuveliswa kwaye isetyenziswe ngokwemigangatho ehambelanayo, ukwenzela ukuba kuqondwe ixabiso lokusetyenziswa kunye nomsebenzi weeflange ezikhethekileyo ekusebenzeni.
