Ipayipi lensimbi ye-alloy ubude obulungisiwe
Incazelo emfushane:
Ipayipi lensimbi elingenamthungo liwuhlobo lwensimbi eyindilinga, eyisikwele kanye nonxande enengxenye engenalutho futhi awekho amajoyinti azungeze ipayipi lensimbi engenamthungo elenziwe ngensimbi yensimbi noma ishubhu eliqinile elingenalutho ngokubhobozwa, bese ligoqwa elishisayo, eligoqiwe elibandayo noma elibandayo elidonswa ipayipi lensimbi engenamthungo line ingxenye yokulawula emaphakathi futhi isetshenziswa kabanzi njengepayipi lokudlulisa uketshezi.Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi linamandla okugoba kanye namandla okugoqa futhi lilula.Kuyinsimbi yesigaba sezomnotho.Isetshenziswa kabanzi ekwenzeni izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhola likawoyela, umshini wokuhambisa imoto, uhlaka lwebhayisikili kanye nepayipi lensimbi elisetshenziswa ekwakheni.
Isethulo esifushane sokusetshenziswa kwamapayipi angenamthungo
I-Seamless Steel Tube ihlukaniswe yaba ishubhu lensimbi eligoqelwe elishisayo (elikhishiwe) elingenamthungo kanye ne-cold-draw.
n (egoqiwe) ithubhu lensimbi engenamthungo.Ishubhu elibandayo (eligoqiwe) lihlukaniswe libe yishubhu eliyindilinga kanye neshubhu elimise okukhethekile izinhlobo ezimbili.Ipayipi lensimbi engenamthungo futhi ngenxa yokusetshenziswa kwayo okuhlukene ihlukaniswe ngezinhlobo eziningana ezilandelayo: 1. Amashubhu ensimbi angenamthungo okusetshenziswa kwesakhiwo (GBT8162-2008).Isetshenziselwa ikakhulukazi isakhiwo esijwayelekile kanye nesakhiwo semishini.Izinto zayo ezimele (uphawu) : I-Carbon Steel, insimbi engu-20,45;I-alloy Steel Q345,20CR, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njll.2. Amashubhu ensimbi angenamthungo okudlulisela uketshezi (GBT8163-2008).Imodeli yokusetshenziswa isetshenziswa kakhulu ukudlulisa ipayipi lamanzi kubunjiniyela nemishini emikhulu.Imele Okubalulekile (umkhiqizo) we-20, Q345, njll.3. AMATHUBU EZINSIMBA ANGENAMTHUNGO AMA-boiler anengcindezi ephansi noma emaphakathi (GB3087-2008) angamashubhu ensimbi angenamthungo adonswa ngokubanda enziwe ngensimbi yekhwalithi ephezulu yekhabhoni yezakhiwo ezahlukahlukene zamashubhu esimusi esishisayo naphakathi nendawo, amashubhu amanzi abilayo. kanye namashubhu e-locomotive boiler ashisa kakhulu, amashubhu amakhulu entuthu, amashubhu amancane entuthu namashubhu ezitini ezikhothame.Izinto ezimele insimbi engu-10,20.
Amashubhu ensimbi angenamthungo (i-GB6479-2000) emishini kamanyolo yamakhemikhali anomfutho ophezulu ayinsimbi esezingeni eliphakeme ye-carbon structural steel kanye namashubhu ensimbi angenamthungo afanele imishini yamakhemikhali namapayipi anokushisa okusebenzayo okungu-40 ~ 400 °C nokucindezela kokusebenza okungu-10 ~ 30 ma. .Okumele okubalulekile kwe-20,16MN, 12CrMo, 12Cr2Mo nokunye.6. AMATHUBU EZINSIMBA ANGENAMTHUNGO OKUQHUKA KAPHETHROLE (GB9948-2006).Imodeli yensiza isetshenziselwa ikakhulukazi ama-boilers, izishintshisi zokushisa namapayipi ahambisa uketshezi ezincibilikweni ze-petroleum.Into emele yona yi-20,12CRMO, 1Cr5Mo, 1Cr19Ni11Nb nokunye.Bulala.Ipayipi lensimbi lokumba i-geological drilling (YB235-70) iwuhlobo lwepayipi lensimbi lokubhola eliwumgogodla, elingahlukaniswa libe yipayipi lokubhoboza, ikhola yokubhola, ipayipi eliwumgogodla, i-casing kanye nepayipi lokumisa.8. Ipayipi lensimbi elingenamthungo (i-GB3423-82) lokumba umnyombo wedayimane liyipayipi lensimbi elingenamthungo lepayipi lokubhoboza, i-core rod kanye ne-casing.9. Ipayipi lokumba uwoyela (YB528-65) ipayipi lensimbi elingenamthungo elisetshenziselwa ukujiya ngaphakathi noma ngaphandle kwamaphethelo amabili epayipi lokumba uwoyela.Ipayipi lensimbi lihlukaniswe ngezinhlobo ezimbili: ucingo oluphendukayo kanye nocingo olungajiki.Ipayipi locingo oluphendukayo lixhunywe nejoyinti, futhi ipayipi lentambo elingajiki lixhunywe ngokuhlanganyela kwethuluzi ngokushisela izinqe.10. Amashubhu ensimbi ekhabhoni nekhabhoni manganese ensimbi engenamthungo emikhumbi (GB/t 5312-2009) alungele ukwakhiwa kwamashubhu ensimbi angenamthungo we-marine grade I, II, ibhoyili ne-superheater carbon kanye nensimbi ye-carbon manganese.Amashubhu ensimbi angenamthungo ohlelo lwamapayipi okucindezela ahlukaniswe amamaki ama-3 ngokuya ngengcindezi yokuklama kanye nezinga lokushisa lokuklama.Izinga lokushisa elisebenzayo lodonga lweshubhu yensimbi engenamthungo kubhayela ne-superheater akufanele lidlule ku-450 °C.526/2000
Bulala.Ishubhu Lensimbi Engenamthungo (i-GB3088-82) yomkhono we-axle shaft yemoto iwuhlobo lwensimbi yekhwalithi ephezulu ye-carbon structural kanye neshubhu yensimbi eshisayo egingqike engenamthungo yomkhono we-axle shaft yemoto kanye neshubhu ye-axle yendlu ye-axle shaft.12. Ipayipi likawoyela elinomfutho ophezulu wenjini yedizili (GB3093-86) liyipayipi lensimbi elidonswa ngokubanda elingenamthungo lokukhiqiza ipayipi elinomfutho ophezulu wesistimu yomjovo wenjini kadizili.13. Amashubhu ensimbi angenamthungo angaphakathi obubanzi obunembile (GB8713-88) amasilinda asebenza ngamanzi kanye nawomoya angamashubhu ensimbi angenamthungo adonswa ngokubanda noma aginqike ngokubandayo anobukhulu obunembile obungaphakathi bobubanzi bokwenziwa kwamasilinda omoya kanye ne-pneumatic.14. Amashubhu ensimbi angenamthungo adonswa ngokubanda noma agingqike ngokubanda (GB3639-83) angamashubhu ensimbi angenamthungo adonswa ngokubanda noma aginqike ngokubandayo anobude obuphakeme bokunemba kanye nokuqedwa okuhle kweSurface yezakhiwo zemishini, okokusebenza kwamanzi.Ukukhetha okunembayo kwepayipi lensimbi elingenamthungo lokukhiqiza ukwakheka komshini noma okokusebenza okudonsa amanzi, kungasindisa kakhulu isikhathi somshini, kuthuthukise ukusetshenziswa kwezinto, futhi kusize ukuthuthukisa ikhwalithi yomkhiqizo.
