Izindlela Zokukhiqiza

(1)Indlela yokuncibilikisa insimbi
I-GB 5310 20MnG insimbi izoncibilika ngesithando somlilo sikagesi kanye nokucwengwa kwesithando somlilo, isiguquli se-oxygen kanye nokucwengisiswa kwesithando somlilo noma indlela yokuncibilikisa i-electroslag.

(2)Izindlela zokukhiqiza kanye nezidingo zezikhala zeshubhu
I-tube engenalutho ingakhiqizwa ngokusakazwa okuqhubekayo, i-die casting noma i-hot rolling (i-forging).

(3)Indlela yokukhiqiza yeshubhu lensimbi
I-GB 5310 20MnG Amashubhu ensimbi azokwenziwa ngokugoqeka okushisayo (ukunwetshwa, ukunwetshwa) noma umdwebo obandayo (ukugingqika).

Isicelo

Isetshenziswa Ikakhulukazi Ukwenza Insimbi Yesakhiwo Sekhabhoni Esezingeni Eliphezulu, Insimbi Yesakhiwo Esiyingxubevange kanye Nemibhobho Yensimbi Engangeni Kokushisa Engenamthungo Ngokucindezela Okuphezulu Nangaphezulu Kwamapayipi Okushisa Okushisayo.

Isetshenziselwa Isevisi Yokucindezela Okuphezulu Kanye Nezinga Lokushisa Eliphezulu (I-Superheater Tube, Ishubhu ye-Reheater, Ishubhu yomhlahlandlela womoya, i-Main Steam Tube yamaBoilers aphezulu kanye ne-Ultra High Pressure).Ngaphansi Kwesenzo Segesi Yokushisa Ephakeme Ye-Flue Kanye Nomusi Wamanzi, Ishubhu Lizokhipha I-Oxidize Futhi Ligqwale.Kudingeka Ukuthi Ipayipi Lensimbi Linokuqina Okuphakeme, Ukumelana Okuphakeme Ne-oxidation kanye Nokugqwala, Nokuzinza Kwesakhiwo Okuhle.

Ibanga Eliyinhloko

Ibanga Lensimbi Yesakhiwo Sekhabhoni Esezingeni Eliphezulu: 20g, 20mng, 25mng
I-Grade Of Alloy Structural Steel: 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, 12cr3movsitib, Etc
Ibanga Lensimbi Emelana Nokushisa Okungagqwali: 1cr18ni9 1cr18ni11nb

Ubude:
Ubude Obujwayelekile Bamapayipi Ensimbi Bungu-4 000 Mm ~ 12 000 Mm.Ngemva Kokubonisana Phakathi Komhlinzeki Nomthengi, Futhi Ugcwalise Inkontileka, Ingalethwa Amapayipi Ensimbi Ngobude Obukhulu Kakhulu Kuno-12 000 Mm Noma Bufushane Kunami 000 Mm Kodwa Hhayi Mfishane Kuno-3 000 Mm;Ubude Obufushane Inombolo Yamapayipi Ensimbi Angaphansi Ko-4,000 Mm Kodwa Hhayi Ngaphansi Ko-3,000 Mm Angeke Adlule U-5% Wesamba Senombolo Yamapayipi Ensimbi Alethiwe

Isisindo Sokulethwa:
Lapho Ipayipi Lensimbi Lilethwa Ngokuhambisana Nobubanzi Bendawo Bangaphandle Kanye Nokuqina Kodonga Lwezibizo Noma Ububanzi Bendawo Begama Nokuqina Kodonga Lwegama, Ipayipi Lensimbi Lilethwa Ngokuhambisana Nesisindo Sangempela.Ingabuye Ilethwe Ngokuvumelana Nesisindo Sethiyori.
Lapho Ipayipi Lensimbi Ilethwa Ngokuhambisana Nobubanzi Ongaphandle Okuzisholo Kanye Nobukhulu Obuncane Bodonga, Ipayipi Lensimbi Ilethwa Ngokuhambisana Nesisindo Sangempela;I-Supply And Demand Parties iyaxoxisana.Futhi Ikhonjisiwe Kunkontileka.Ipayipi Lensimbi Lingabuye Lilethwe Ngokuvumelana Nesisindo Sokucabanga.

Ukubekezelela Isisindo:
Ngokwezimfuneko Zomthengi, Ngemva Kokubonisana Phakathi Komhlinzeki Nomthengi, Futhi Nenkontileka, Ukuchezuka Phakathi Kwesisindo Sangempela Nesisindo Esicatshangwayo Sepayipi Lensimbi Lokulethwa Kuzohlangabezana Nezimfuneko Ezilandelayo:
A) Ipayipi Lensimbi Elilodwa: ± 10%;

Isidingo Sokuhlola

Ukuhlolwa kwe-Hydraustatic:
Ipayipi Lensimbi Kufanele Lihlolwe Ngamanzi Ngalinye Ngalinye.Ingcindezi Yokuhlola Ephezulu Ingama-20 MPa.Ngaphansi Kwengcindezi Yokuhlola, Isikhathi Sokuzinza Akufanele Sibe Ngaphansi Ko-10 S, Futhi Ipayipi Lensimbi Akufanele Livuze.
Ngemuva kokuthi Umsebenzisi Evumile, Ukuhlolwa Kwe-Hydraulic Kungashintshwa Ukuhlola Kwamanje kuka-Eddy Noma Ukuhlola Ukuvuza KweMagnetic Flux.

Ukuhlola Okungonakali:
Amapayipi Adinga Ukuhlolwa Okuningi Kufanele Ahlolwe Ngomshini Ngalinye Ngalinye.Ngemuva kokuthi Ingxoxo Idinga Imvume Yeqembu Futhi Icaciswe Kunkontileka, Okunye Ukuhlola Okungabhidli Kungangezwa.

Ukuhlolwa kokucaba:
Amashubhu Anobubanzi Bangaphandle Omkhulu Kuno-22 Mm Azofakwa Ukuhlolwa Kokucaba.Akukho Ukuwohloka Okubonakalayo, Amachashazi Amhlophe, Noma Ukungcola Okufanele Kuvele Phakathi Naso sonke Isilingo.

Ukuhlolwa kwe-Flaring:
Ngokwezimfuneko Zomthengi Futhi Okushiwo Kunkontileka, Ipayipi Lensimbi Elinobubanzi Ongaphandle ≤76mm Nokuqina Kwezindonga ≤8mm Kungenziwa Ukuhlola Ukuvutha .Ukuhlolwa Kwenziwa Emazingeni Okushisa Egumbi Nge-taper engu-60 °.Ngemva Kokuvutha, Izinga Lokuvutha Kodayamitha Wangaphandle Kufanele Lihlangabezane Nezimfuneko Zethebula Elilandelayo, Futhi Izinto Zokuhlola Akumele Zibonise Imifantu Noma Iziklebhu.
