I-JIS B2311 Carbon Steel Butt Weld Stub End Lap Joint Flanging

Isingeniso Somkhiqizo

I-JIS B2311 Stub end iyinsizakalo yokuxhuma amapayipi ehlangabezana ne-Japanese Industrial Standard (JIS) futhi ngokuvamile isetshenziselwa ukuxhuma i-carbon steel namapayipi ensimbi engagqwali.Iqukethe izingxenye ezimbili: eyodwa "umama" (noma main) ukuphela okufanayo nobubanzi obungaphandle bepayipi, kanti enye "ingane" (noma isigqila) isiphetho esihlukile kububanzi obungaphandle bepayipi. ipayipi, ngokuvamile lifushane kunokuphela komama.

Izinto zokwakha ze-JIS B2311 Stub end imvamisacarbon steel noma insimbi engagqwali, njenge-SUS304, SUS316, njll. Ingaphezulu layo lingelashwa ngezindlela ezinjengokwenza i-galvanizing, ukupenda, ukuqhunyiswa kwesihlabathi, njll. ukuthuthukisa ukumelana nokugqwala kanye nobuhle.
Indlela yokufaka ye-JIS B2311 Stub end ingaba i-welding, uxhumano lwentambo, uxhumano lwe-flange, njll. Phakathi kwazo, ukuxhuma kwe-welding kuyindlela evame ukusetshenziswa kakhulu, ngokuvamile kusetshenziswa i-butt welding ukuxhuma ukuphela kwe-Stub nepayipi, ngaleyo ndlela yakhe ipayipi eliphelele. uhlelo.

Kufanele kuqashelwe ukuthi impahla kanye nokucaciswa kwe-JIS B2311 Stub end kudingeka kukhethwe ngokusekelwe endaweni yangempela yokusetshenziswa kanye nezidingo zamapayipi ukuqinisekisa ukuphepha nokuthembeka kwesistimu yamapayipi.Ngaphezu kwalokho, ukuhlolwa nokuhlolwa okwanele kuyadingeka ngaphambi kokufakwa ukuze kuqinisekiswe ikhwalithi nokuzinza koxhumano.

Ubukhulu, isilinganiso sokucindezela, kanye nobubanzi bokusetshenziswa kwe-JIS B2311 Stub end bumi kanje:
Ubukhulu: Kusukela ku-DN15 (1/2 intshi) kuya ku-DN600 (24 intshi).
Izinga lokucindezela: kusuka ku-5K kuya ku-40K.
Ububanzi bokusebenza: Isetshenziswa kakhulu ezinhlelweni zamapayipi ahlukahlukene ezimbonini ezinjengamakhemikhali, i-petroleum, igesi yemvelo, ukwakhiwa, imishini, imithi, insimbi, ukudla, kanye nokwakhiwa kwemikhumbi.

Ukuqhathanisa

Uma kuqhathaniswa nezinye izesekeli zokuxhuma amapayipi, ukufana okuyinhloko nomehluko we-JIS B2311 Stub end imi kanje:
Ukufana:
Njengezinye izesekeli zokuxhuma amapayipi, i-JIS B2311 Stub end isetshenziselwa ukuxhuma amapayipi anosayizi abahlukene noma izinto zokwakha.
I-JIS B2311 Stub end, njengezinye izesekeli zokuxhuma amapayipi, inezindlela ezihlukene zokuxhuma ezifana nokushisela, ukucupha, kanyeama-flange.
Umehluko:
I-JIS B2311 Stub end yamukela izindinganiso zezimboni zase-Japan, futhi kungase kube khona umehluko ngosayizi, ukucaciswa, nezinto zokwakha uma kuqhathaniswa namanye amazinga afana ne-ASME, EN, DIN, njll.
Usayizi nebanga lokulinganisa ingcindezi le-JIS B2311Isiphetho se-stubincane uma kuqhathaniswa, isibonelo, ubukhulu bayo obukhulu yi-DN600 futhi isilinganiso sayo sokucindezela esiphezulu singu-40K.
Ububanzi bokusetshenziswa kokuphela kwe-JIS B2311 Stub nakho kulinganiselwe uma kuqhathaniswa, ikakhulukazi ezisebenza kumasistimu amapayipi ahlukahlukene ezimbonini ezifana namakhemikhali, uphethiloli, igesi yemvelo, ukwakhiwa, imishini, imithi, insimbi, ukudla, kanye nokwakhiwa kwemikhumbi.

Kafushane, i-JIS B2311 Stub end iwukulinganisa koxhumano lwepayipi oluhlangabezana nezindinganiso zezimboni zase-Japan, ezinemikhawulo ethile kusayizi walo, isilinganiso sokucindezela, nokusebenza.Uma kuqhathaniswa nezinye izesekeli zokuxhuma amapayipi, zinokufana okuthile kanye nomehluko odinga ukukhethwa ngokusekelwe endaweni yangempela yokusetshenziswa kanye nezidingo.
