Intsimbi yentsimbi yokuwelda iflange yentamo

steel stainless welding intamo flange Featured Umfanekiso

Inkcazelo emfutshane:

I-welding neck flange idla ngokubizwa ngokuba yi "high hup" flange. Yenzelwe ukudlulisa uxinzelelo kumbhobho, ngaloo ndlela ukunciphisa uxinzelelo oluphezulu kwisiseko seflange. I-welding neck flange yeyona flange eyilwe kakuhle enebutt-welded kwezo zikhoyo ngoku ngenxa yexabiso layo lendalo.

Iinkcukacha zeMveliso

I-butt welding flange ayikho lula ukuyikhubaza, itywinwe kakuhle, isetyenziswa ngokubanzi, ineemfuno ezihambelanayo zokuqina kunye nokunwebeka kunye nengqiqo ye-welding ye-butt, i-welding umgama ukusuka kumphezulu ohlangeneyo mkhulu, umphezulu odibeneyo ukusuka kwi-welding deformation yobushushu, kuthatha ngaphezulu Ulwakhiwo lomzimba wokhohlokhohlo oluntsonkothileyo, olulungele uxinzelelo okanye ukuguquguquka kobushushu bombhobho okanye ubushushu obuphezulu, uxinzelelo oluphezulu kunye nombhobho wobushushu obuphantsi, osetyenziswa ngokubanzi kwi-PN engaphezu kwe-2.5MPa yombhobho kunye noqhagamshelo lwevalvu; Ikwasetyenziselwa ukuthutha umbhobho ophakathi obiza imali eninzi, onokutsha, oqhumayo.

Umgangatho woyilo

I-butt welded flange yenziwa ngokubanzi ngenkqubo yokubunjwa okanye yokwenziwa. Xa isitya sentsimbi okanye intsimbi yecandelo isetyenzisiwe, ezi mfuno zilandelayo kufuneka zifezekiswe:
1.I-butt welding flange kufuneka ihlolwe nge-ultrasonic, ngaphandle kweziphene ze-delamination;
2.Ufanele unqunyulwe ube yimichilo ecaleni kwendlela yentsimbi, idityaniswe kwindandatho ngokugoba, kunye nomphezulu wentsimbi ukwenza i-cylinder yendandatho. Ipleyiti yentsimbi ayinakwenziwa ngokuthe ngqo kwiflange yentsimbi yentsimbi;
3.I-butt weld yeringi kufuneka yamkele i-weld yokungena ngokupheleleyo;
4. I-butt weld yendandatho iya kufumana unyango lwe-post-welding heat, kwaye ixhomekeke kwi-100% ray okanye ukuhlolwa kwe-ultrasonic, eya kuhlangabezana neemfuno ze-II ze-JB4730 kunye nokuhlolwa kwe-ultrasonic kuya kuhlangabezana neemfuno ze-I ze-JB4730.
Ukuthambeka kwentamo yangaphandle ye-butt welding flange akufanele ibe ngaphezu kwe-70 °. Iiparamitha zobugcisa ze-butt welding flange zilawulwa ngokungqongqo ngexesha lemveliso kunye ne-welding ukuqinisekisa ukuba inokudlala indima yayo kunye nexabiso elipheleleyo kwimveliso kunye nokusetyenziswa.
