2. Amapayipi ensimbi angenamthungo ngezinhloso ezijwayelekile nawo ahlinzekwa ngokuya ngokwakheka kwamakhemikhali kanye nezakhiwo zemishini, futhi ngokusho kokuhlolwa kwe-hydraulic. Amapayipi ensimbi angenamthungo athwala umfutho we-fluid kumele aphumelele ukuhlolwa kwe-hydraulic pressure.
3. Amapayipi angenamthungo anenhloso ekhethekile asetshenziswa kumabhayela, ukuhlola umhlaba, ama-bearings, ukumelana ne-asidi, njll. Okufana namapayipi okumba i-petroleum geological,amapayipi okuqhumaembonini ye-petrochemical,amapayipi obhayela, amapayipi anamanzi kanye namapayipi ensimbi anesakhiwo esinembayo esiphezulu wezimoto, ogandaganda nokundiza.
Amapayipi ensimbi angenamthungo asetshenziselwa ikakhulukazi izakhiwo ezijwayelekile kanye nezakhiwo zemishini. Izinto zayo ezimele (amabanga): i-carbon steel No. 20, No. 45 steel; insimbi ye-alloyQ345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njll.
Amapayipi ensimbi angenamthungo okuthutha uketshezi ikakhulukazi asetshenziselwa ukuthutha amapayipi oketshezi kubunjiniyela kanye nemishini emikhulu. Izinto ezimele (amabanga) zingama-20, Q345, njll.
Amapayipi ensimbi angenamthungo ama-boiler anengcindezi ephansi naphakathi asetshenziselwa ikakhulukazi amapayipi athutha uketshezi lwengcindezi ephansi naphakathi kuma-boilers ezimboni kanye nama-boilers asekhaya. Izinto ezimele ziyi-No. 10 kanye ne-20 # yensimbi.
Amapayipi ensimbi angenamthungo amaboiler anengcindezi ephezulu asetshenziselwa ikakhulukazi izihloko zokuthutha uketshezi olunomfutho ophezulu kanye namapayipi esitshalweni samandla kanye namabhoyili ezitshalo zamandla enuzi. Izinto ezimele ziyi20G, 12Cr1MoVG, 15CrMoG, njll.
Amapayipi ensimbi angenamthungo emishini kamanyolo enengcindezi ephezulu asetshenziselwa ikakhulukazi ukuthutha amapayipi amanzi anokushisa okuphezulu kanye nomfutho ophezulu wezinto zokusebenza zikamanyolo. Izinto ezimele ziyi-20, 16Mn,12CrMo, 12Cr2Mo, njll.
Amapayipi ensimbi angenamthungo wokuqhekeka kwe-petroleum asetshenziswa kakhulu kuma-boilers, izinto zokushintsha ukushisa namapayipi okuthutha uketshezi ezitshalweni ezincibilikisa i-petroleum. Izinto zayo ezimele ziyi-20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, njll.
Amapayipi ensimbi angenamthungo amasilinda egesi asetshenziswa ngokuyinhloko ukwenza amasilinda egesi ahlukahlukene kanye ne-hydraulic gas. Izinto zayo ezimele ziyi-37Mn, 34Mn2V, 35CrMo, njll.
Amapayipi ensimbi angenamthungo afakwe emanzini ashisayo asetshenziselwa ama-hydraulic props, asetshenziswa kakhulu ukwenza izisekelo zama-hydraulic, amasilinda namakholomu ezimayini zamalahle, kanye namanye amasilinda namakholomu ama-hydraulic. Izinto zayo ezimele ziyi-20, 45, 27SiMn, njll.
Amapayipi ensimbi angenamthungo adonswa ngokubanda noma agoqeke ngokubanda asetshenziselwa ikakhulukazi izakhiwo zemishini kanye nemishini yokucindezela ikhabhoni, edinga ukunemba kobukhulu obuphezulu kanye nokuqedwa okuhle kwendawo. Izinto zayo ezimele zihlanganisa i-20, i-45 yensimbi, njll.
Amapayipi ensimbi adonswa ngokubanda angenamthungo kanye namapayipi ensimbi anomumo okhethekile asetshenziswa ngokuyinhloko ukwenza izingxenye nezingxenye ezihlukahlukene zesakhiwo. Zenziwe ngensimbi yesakhiwo sekhabhoni ephezulu kanye nensimbi yesakhiwo esine-alloy ephansi.
Amapayipi ensimbi angenamthungo anembile obubanzi bangaphakathi bamasilinda asebenza ngamanzi kanye nawomoya asetshenziswa ngokuyinhloko ukwenza amapayipi ensimbi adonswa ngokubanda noma agingqike ngokubanda angenamthungo anobubanzi obunemba bangaphakathi bamasilinda asebenza ngamanzi kanye nawomoya. Izinto zayo ezimele ziyi-20, 45 steel, njll.
