Izizathu zokugqwala kwepayipi elingenasisekelo lensimbi

Enye ipayipi elingenacala le-welded ngemuva kokuphothulwa kokukhiqizwa, ngemuva kwesikhathi lapho kunokugqwala ebusweni, ngisho nokuqhekeka, kungani kunjalo?

Ngoba kwinqubo yokukhiqiza yamapayipi we-welded, isinyathelo esibaluleke kakhulu asinakwa, okungukuthi, ''. Enqubweni yokubhema insimbi nokukhiqiza, sizolungisa ifomula yento yokwenza insimbi ifinyelele izici esizidingayo, enjenge, nk, i-mo, MN, MO, i-SI kanye nezinye izinto zensimbi. Ukusebenza okudingeka sikuthuthukise ukumelana nokuqina okuphezulu kwensimbi, okuyinto esiyibiza ngensimbi engagqwali. Ukumelana nokugqwala kwensimbi engenasici kuvela entweni equkethwe kufomula - Cr. Lapho okuqukethwe kweTaipa kufinyelela inani eliphakeme, ukumelana nokugqwala kwensimbi kuzothuthukiswa kakhulu. Okuqukethwe okujwayelekile kwensimbi engagqwali kufanele kufinyelele okungenani i-10,5%.

Izinhlobo Ezivamile Zokugqwala: Ukugqwala okujwayelekile, ukugcwala kwengcindezelo

Ukugqwala okuhlanganyele, into yayo yokugqwala kwezinhlangano zenqubo ye-welding yepayipi elinenkani, ngenxa yokushisa okuphezulu okuholela ekuthini i-chromium compact (CR23C6 into ye-chromium i-chomium

Ukugqwala kwengcindezi kuvela kumandla okuphendula akhiqizwa lapho umucu wensimbi ukhubazeka yingcindezi yangaphandle ngesikhathi senqubo ye-welding esiteji esenzayo, futhi uzohlala ngaphakathi kwepayipi elibekiwe ngemuva kokushiswa. Uma kungaqediwe ngesikhathi, ubulukhuni bepayipi elinama-welded buzoba buphezulu kakhulu, futhi kunzima ukwenza ukucubungula okulandelayo.

Ngenxa yalezi zinkinga ezimbili ezisezingeni eliphakeme, imishini yethu ingafinyelela kanjani ikhambi eliphelele?

Izici zomshini okhanyayo we-Annealing yenkampani yeTechnology Company:

1, okusanhlamvu okuhle, ukwakheka kwensimbi efanayo nokwakheka.

2, Qeda ukucindezelwa kwangaphakathi kwensimbi nokuvimbela ukonakala nokuqhekeka.

3, yehlisa ubulukhuni bensimbi, ukuthuthukisa i-plastiki, ukuze kusebenze ukucubungula okulandelayo.

Izici ezinhlanu ezinemininingwane yemishini ekhanyayo:

1, umsebenzi wokufaka uphawu lomthwalo womlilo ulungile, ukusebenza kahle kokubekwa uphawu kuzovumela ukulahleka kwegesi emzimbeni wesithando, akunakudlala indima ekhanyayo.

2, igesi yamanzi emzimbeni wesithando somlilo izodala ukuthi igesi yokushisa yokushisa ibe yinhle, futhi igesi yamanzi evulekile izonamathiselwa ebusweni bepayipi lensimbi engenasici nangama-oxidized.

I-3, ingcindezi kagesi esidumelweni somlilo, ukuze igweme ukungena kwegesi kwangaphandle emzimbeni wesithando, ingcindezi esithandweni somlilo kufanele ibe nkulu kunengcindezi yangaphandle.

I-4, i-anneling lokushisa lokulawula lokushisa, noma ngabe uzuze izinga lokushisa elihle kakhulu lokushisa kwensimbi yensimbi.

I-5, igesi edingekayo kwinqubo yokungenisa izikhalazo, igesi yensimbi engenasici ingukukhethwa kokuqala kwe-hydrogen emsulwa, ngoba ubumsulwa begesi buhle kakhulu, bungagange ngo-100%, abakwazi ukuceba umoya-mpilo omningi, igesi yamanzi. Ngoba igesi yisizathu esiyinhloko sokuthinta ikhwalithi yamapayipi ensimbi engagqwali.
