Spiral Welded Steel Tube SSAW Carbon Steel Pipe Canghai Nuclear
Incazelo Yemikhiqizo
Ipayipi lensimbi elivunguzayo liyipayipi lensimbi elivunguzayo elenziwe ngekhoyili yensimbi eyi-strip njengempahla eluhlaza, evamise ukufudumala ekhishwe futhi eshiselwe inqubo yokushisela ye-arc enezinhlangothi ezimbili ezizenzakalelayo. Ipayipi lensimbi elivunguzayo lithumela insimbi ye-strip kuyunithi yepayipi yokushisela, futhi insimbi ye-strip igoqwe ngamaroll amaningi. Insimbi ye-strip igoqwa kancane kancane ukuze yakhe ishubhu eliyindilinga elingenalutho elinesikhala esivulekile. Lungisa ukuncishiswa kwe-extrusion roll ukuze ulawule igebe lokushisela ku-1~3mm, futhi wenze zombili iziphetho ze-weld crater ziguqe.

I-Summerged Arc Welding (SAW):
Ipayipi elishiselwe i-Spiral: Insimbi yesakhiwo sekhabhoni ephansi noma i-alloy structural steel strip igoqwa ibe yishubhu elingenalutho ngokwe-Angle ye-helix ethile (ebizwa ngokuthi i-Angle yokuma), bese umphetho wepayipi ushiselwa ndawonye, ongakhiqiza ipayipi elikhulu lensimbi elinobubanzi obunomugqa omncane. Ukucaciswa kuvezwa ubukhulu be-diameter * yangaphandle yodonga, futhi ipayipi elishiselwe kufanele liqinisekise ukuthi ukuhlolwa komfutho wamanzi, amandla aqinile we-weld nokusebenza kokugoba okubandayo kufanele kuhlangabezane nezidingo.
Ukukhiqizwa kwamapayipi ensimbi ane-spiral ashiselwe kungabonisa izinzuzo zekhwalithi ephezulu nokusebenza kahle okuphezulu. Umthamo wokukhiqiza weyunithi yepayipi elishiselwe okuvunguzayo ulingana namasethi angu-5-8 wemishini yamapayipi ashiselwe ngomthungo oqondile. Indlela yokwenza imigqa yokukhiqiza imishini yokugoqa yamapayipi amaningi ihlangabezane nezinga elifanayo lokukhiqiza, okungukuthi, ukukhiqiza ngokuvumelana nenqubo yokukhiqiza ehlanganisiwe kanye nesistimu yokuqinisekisa ikhwalithi ukuze kuhlangatshezwane nekhwalithi yokushisela Izidingo kanye nezigaba zokukhiqiza amapayipi kuzoba umsebenzi onzima.
Umkhiqizo Bonisa
1.Amandla okuqhuma kwe-static high pressure.
2.Ukuqina okuhle.
3.Amathuba aphansi okuphuka okungazinzile.
I-4.I-brittleness enhle ekushiseni okuphansi.
5.Low umjikelezo ukukhathala amandla aphezulu.
6.Ukumelana nokugqwala kwamakhemikhali okuhle kakhulu.
7.Izakhiwo eziphezulu zemishini.
I-8.Ukumelana nokugqoka okuqinile nokunamathela.
