Ishintsha ezenziwe ngensimbi: izinhlobo kanye Ububanzi yabo

Phakathi kudvweba nekwakhiwa iphayiphi izinhlelo ukunakekelwa okukhethekile ikhokhelwa elinemininingwane futhi umphetho amalunga amapayipi nge diameters ezahlukene. Etigabeni ukuqinisa esetshenziswa enkompolo, othiwa steel ushintsho futhi sivumele kophuzo imvelo ukusebenza zombili izinkomba. Lokhu okokusebenza Ezimweni eziningi zithandwa kakhulu. abakhiqizi Russian ukukhiqiza ejwayelekile ukuhwebelana steel ngokuhambisana GOST 17378-2001 kanye ukuhwebelana ezikhethekile bakubheka at emalungeni, akuyona efanele Standardization nemingcele. Zimbili izinhlobo valve ngayo nefunda ngayo amapayipi efakwe: le ome njengeqanda futhi eyindilinga.

Esimweni sokuqala, kunechweba shift bese yokuveza uketshezi ukugeleza-eksisi by esincane, ezingasetshenziswa namanje nomthelela ukuhamba kwezimoto. Lapha, i-ephansi iba indawo uxhumano.

Esimeni sesibili, uhlelo steel inguqulelo amashubhu eyindilinga kusiza nokunamathisela ngomthofu amalunga omzimba ngaphandle ukufuduka kanye eksisi ukugeleza ukusebenza.

Flow edabula indawo evulekile iphayiphi ngesikhathi sokuphumula, inyuka noma lehla, kanjalo ukucindezela zokusebenza. Le nqubo kuxhomeke ukwedlulela steel.

Indaba womshini valve ihlukile amamaki steel. Ngomsebenzi wokugqokwa e ongaphakeme ingcindezi imvelo futhi okungezona ezonakalisayo steel ukuhwebelana zenziwa kusukela carbon steel St3, St10, St20. Le mikhiqizo bephume amamaki steel ezifana 12X18H10T, 15X5M isicelo nalapho bethutha nolaka uketshezi ukugeleza, e ekhethekile izingoma steel engezwa ngcono ukumelana ukugqwala futhi ihlala isikhathi eside. Of steel nge ukugqwala ongaphakeme ukumelana ukuhwebelana ukukhiqiza steel nge enamathela zinc kwelinye ungqimba.

Isici esivelele kakhulu ukuqinisa esiphezulu ukusebenza ingcindezi kuncike impahla kanye nemingcele yejeyomethri ukumelana yokusebenza ingcindezi ku ezahlukene 4 kuya 160 MPA, elihambisana ovumelekile esiphezulu.

Izinguquko steel ashiselwe yakhelwe ukusebenza ngesikhathi ingcindezi 16 MPA nokuxhashazwa okushisa kusuka -70 kuya + 450 ° C, futhi amelana izinga lokushisa nokucindezelwa umehluko.
Ukukhiqizwa yobuchwepheshe obukhona ungaveza indlela rebar of nginyathela noma ekubunjweni electroslag centrifugal, kokuthola it ngaphandle komzamo, okwandisa nokwethenjelwa ukuphila service.

Izidingo zezinto ezibonakalayo imiyalelo singesifanele futhi inhlangano:

- i-steel kufanele ibe ductility okusezingeni eliphezulu, isakhiwo svarimostyu futhi ubunzima ;

- izimbobo ukuhambisana proportionality inguqulelo nogwali roundness futhi indiza ekupheleni ubuso.

Ukukhetha ukuhwebelana steel, kumele zithobele nalezi zidingo ezilandelayo:

- itheku futhi esidayisa ipayipi ububanzi;

- uhlobo impahla kanye namandla ayo izakhiwo;

- Ukuhlola medium ukusebenza kanye nomehluko lokushisa;

- Operating ingcindezi.
