Insimbi engagqwali welding neck flange

Insimbi engagqwali yokushisela intamo flange Isithombe esifakiwe

Incazelo emfushane:

I-welding neck flange ijwayele ukubizwa ngokuthi i-"high hup" flange. Idizayinelwe ukudlulisa izingcindezi epayipini, ngaleyo ndlela yehlise ukugxila okuphezulu kwengcindezi phansi kwe-flange. I-welding neck flange iyi-flange ene-butt-welded eklanywe kakhulu kunaleyo etholakalayo njengamanje ngenxa yenani layo lesakhiwo.

Imininingwane Yomkhiqizo

I-butt welding flange akulula ukuyishintsha, ivalwe kahle, isetshenziswa kabanzi, inezidingo ezihambisanayo zokuqina nokunwebeka kanye nenguquko enengqondo ye-butt welding thinning, ibanga le-welding ukusuka endaweni ehlangene likhulu, indawo ehlangene esuka ekushiseni kwe-welding deformation, idinga okwengeziwe. isakhiwo somzimba wokukhwehlela, esifanele ingcindezi noma izinga lokushisa elishintshashintshayo lepayipi noma izinga lokushisa eliphezulu, umfutho ophezulu kanye nepayipi lokushisa eliphansi, Ivamise ukusetshenziselwa i-PN engaphezu kuka-2.5MPa ipayipi noxhumo lwevalvu; Futhi esetshenziselwa ukuthutha amapayipi aphakathi nendawo abizayo, avuthayo, aqhumayo.

Idizayini ejwayelekile

I-butt welded flange ngokuvamile yenziwa ngenqubo yokufoja noma yokubumba. Lapho kusetshenziswa ipuleti lensimbi noma ingxenye yensimbi, lezi zidingo ezilandelayo kufanele zihlangatshezwe:
1.I-butt welding flange kufanele ihlolwe nge-ultrasonic, ngaphandle kwamaphutha e-delamination;
2.Kufanele inqunywe ibe yimichilo ngokulandela isiqondiso sokugoqa kwensimbi, ihlanganiswe ibe yindandatho ngokugoba, futhi ubuso bensimbi benze isilinda sendandatho. Ipuleti lensimbi akufanele lifakwe ngomshini ngqo kwi-flange yokushisela izinqe zentanyeni;
3.I-butt weld yeringi kufanele ifake i-weld yokungena ngokugcwele;
4. I-butt weld yeringi izokwenziwa ukwelashwa kokushisa kwangemuva kokushisela, futhi ihlolwe yi-ray engu-100% noma i-ultrasonic, okuzohlangabezana nezidingo ze-II ze-JB4730 futhi ukuhlolwa kwe-ultrasonic kuzohlangabezana nezidingo ze-I ze-JB4730.
Umthambeka wentamo yangaphandle ye-butt welding flange akufanele ibe mkhulu kuno-70°. Imingcele yezobuchwepheshe ye-butt welding flange ilawulwa ngokuqinile ngesikhathi sokukhiqiza kanye nokushisela ukuze kuqinisekiswe ukuthi ingadlala indima yayo kanye nenani ngokugcwele ekukhiqizeni nasekusetshenzisweni.
