Kusukela ngeminyaka yawo-1930s, ngokuthuthuka okusheshayo kokukhiqizwa kwe-strip eqhubekayo esezingeni eliphezulu kanye nokuthuthuka kobuchwepheshe bokushisela nokuhlola, ikhwalithi yama-welds ibilokhu ithuthukiswa ngokuqhubekayo, futhi izinhlobonhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuye kwanda.Mthungo ipayipi lensimbi.Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi ahlanganisiwe we-seam aqondile kanye namapayipi ashiselwe okuvunguza ngokwendlela yokushisela.Ukuhlukaniswa ngendlela yokukhiqiza: inqubo yokuhlukanisa-ipayipi elishiselwe i-arc, ipayipi elishiselwe ukumelana, (imvamisa ephezulu, imvamisa ephansi) ipayipi elishiselwe igesi, ipayipi elishiselwe esithandweni.
Amapayipi ashiselwe ububanzi obuncane ashiselwe ngomthungo oqondile, kuyilapho amapayipi amakhulu ashiselwe ubukhulu bawo ashiselwe ngokuzungeza.Ngokusho kokuma kokuphela kwepayipi lensimbi, lihlukaniswe libe yipayipi elihlanganisiwe eliyindilinga futhi elimise okukhethekile (isikwele, unxande, njll.) ipayipi elihlanganisiwe;ngokwezinto ezihlukene kanye nokusetshenziswa, ihlukaniswe yaba uketshezi lwezimayini Ukudlulisa amapayipi ensimbi ashiselwe, amapayipi ensimbi ashiselwe ukuhambisa uketshezi olunomfutho ophansi, amapayipi ensimbi ashiselwe kagesi ama-roller amabhande, njll. Ngokusho kwetafula losayizi ezingeni lamanje likazwelonke , hlunga ngobubanzi obungaphandle * ukujiya kodonga kusuka kokuncane kuye kokukhulu.
Izinto ezisetshenziswa kakhulu amapayipi ashiselwe yilezi: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Nir19Nir01Cr01, njll.
Izikhala ezisetshenziselwa amapayipi ensimbi ashiselwe amapuleti ensimbi noma ama-strip steels, ahlukaniswe abe amapayipi ashiselwe esithandweni, amapayipi kagesi ashiselwe (ukumelana okushiselwe) namapayipi a-arc ashiselwe ngokuzenzakalelayo ngenxa yezinqubo zawo zokushisela.Ngenxa yamafomu ayo ahlukene we-welding, ingahlukaniswa ngezinhlobo ezimbili:
umthungo oqondile ipayipi ashiselwe kanye Kuvunguza ashiselwe ipayipi.Ngenxa yokuma kwayo kokuphela, ihlukaniswe ipayipi elishiselwe eliyindilinga kanye nepayipi elishiselwe okukhethekile (isikwele, isicaba, njll.).Amapayipi ashiselwe ahlukaniswe ngezinhlobo ezilandelayo ngenxa yezinto zawo ezihlukene kanye nokusetshenziswa kwawo:
I-GB/T3091-2008 (Amapayipi ensimbi ashiselwe okuthutha uketshezi olunomfutho ophansi): Ikakhulukazi asetshenziselwa ukuthutha amanzi, igesi, umoya, uwoyela, ukushisisa amanzi noma isitimu kanye nezinye ngokuvamile uketshezi olunomfutho ophansi nezinye izinjongo.Into emele yona yile: Insimbi yezinga le-Q235A.
I-GB/T14291-2006 (Ipayipi Lensimbi Elishiselwe Lokuthutha Uketshezi Lwezimayini): Isetshenziselwa kakhulu amapayipi ensimbi ashiselwe ngomthungo oqondile wokucindezela komoya wasemayini, i-drainage, negesi yokukhipha i-shaft.Impahla emele i-Q235A, iBanga B lensimbi.
I-GB/T12770-2002 (Ipayipi lensimbi engagqwali elishiselwe isakhiwo sokusebenza): Isetshenziselwa kakhulu imishini, izimoto, amabhayisikili, ifenisha, umhlobiso wamahhotela nezindawo zokudlela kanye nezinye izingxenye zemishini nezingxenye zesakhiwo.Izinto zayo ezimele ziyi-0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, njll.
I-GB/T12771-1991 (Ipayipi lensimbi engagqwali elishiselwe ukuthutha uketshezi): Isetshenziselwa kakhulu ukuthutha imidiya egqwalayo enengcindezi ephansi.Izinto ezimele i-0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, njll.
Ngaphezu kwalokho, amapayipi ensimbi engagqwali ashiselwe umhlobiso (GB/T 18705-2002), insimbi engagqwali ashiselwe amapayipi umhlobiso yezakhiwo (JG/T 3030-1995), futhi ashiselwe amapayipi ensimbi for exchangers ukushisa (YB4103-2000).
Ipayipi elihlanganisiwe le-Longitudinal linenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi kanye nentuthuko esheshayo.Amandla amapayipi ashiselwe okuvunguzayo ngokuvamile aphezulu kunalawo amapayipi ashiselwe ngomthungo oqondile.Okungenalutho okuncane kungasetshenziswa ukukhiqiza amapayipi ashiselwe anamadayimitha amapayipi amakhulu, futhi i-billet enobubanzi obufanayo ingase isetshenziselwe ukukhiqiza amapayipi ashiselwe anobubanzi obuhlukahlukene bepayipi.Kodwa uma kuqhathaniswa nepayipi le-seam eliqondile lobude obufanayo, ubude be-weld bukhuphuka ngo-30-100%, futhi isivinini sokukhiqiza siphansi.
Amapayipi amakhulu ashiselwe ububanzi noma awugqinsi enziwa ngokuqondile ngezimbobo zensimbi, kuyilapho amapayipi amancane ashiselwe namapayipi ashiselwe ngodonga oluncane adinga kuphela ukushiselwa ngokuqondile ngemicu yensimbi.Khona-ke ngemva kokupholisha okulula, umdwebo ulungile.
Isengezo: Ipayipi elishiselwe lishiselwe nge-strip steel, ngakho aliphakeme njengepayipi elingenamthungo.
Imikhiqizo isetshenziswa kabanzi kwezobunjiniyela bokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla, ukuchelela ngenkasa kwezolimo, kanye nokwakhiwa kwamadolobha.Ingenye yemikhiqizo engu-20 ebalulekile eyenziwe ezweni lami.
Isetshenziselwa ukuthuthwa kwamanzi: ukuhlinzekwa kwamanzi kanye nokukhipha amanzi.Isetshenziselwa ukuthuthwa kwegesi: igesi yamalahle, umusi, igesi ye-petroleum ewuketshezi.
Ngezinhloso zesakhiwo: njengamapayipi okunqwabelanisa namabhuloho;amapayipi amadokhu, imigwaqo, nezakhiwo zokwakha.
