2. Amapayipi ensimbi angenamthungo ngezinjongo ezijwayelekile nawo ahlinzekwa ngokuya ngokwakheka kwamakhemikhali kanye nezakhiwo zemishini, kanye nangokuya ngokuhlolwa kwe-hydraulic. Amapayipi ensimbi angenamthungo athwala umfutho woketshezi kumele aphumelele ukuhlolwa komfutho we-hydraulic.
3. Amapayipi angenamthungo asetshenziswa ngokukhethekile kuma-boiler, ekuhlolweni kwe-geological, kuma-bearings, ekumelaneni ne-asidi, njll. Njengamapayipi okubhoboza i-geological kaphethiloli,amapayipi aqhekekayoembonini ye-petrochemical,amapayipi ebhoyila, amapayipi okuthwala kanye namapayipi ensimbi akhiwe ngendlela enembile kakhulu ezimotweni, ogandaganda kanye nezindiza.
Amapayipi ensimbi angenamthungo asetshenziswa kakhulu ezakhiweni ezijwayelekile kanye nezakhiwo zemishini. Izinto ezimele wona (amazinga): insimbi yekhabhoni No. 20, insimbi No. 45; insimbi ye-alloyQ345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, njll.
Amapayipi ensimbi angenamthungo okuthutha uketshezi asetshenziswa kakhulu ekuthuthweni kwamapayipi oketshezi kwezobunjiniyela kanye nemishini emikhulu. Izinto ezimele (amamaki) yi-20, Q345, njll.
Amapayipi ensimbi angenamthungo ama-boiler aphansi naphakathi nendawo asetshenziswa kakhulu kumapayipi athutha uketshezi oluphansi noluphakathi kuma-boiler ezimboni kanye nama-boiler asekhaya. Izinto ezimele ziyinsimbi enguNombolo 10 no-20#.
Amapayipi ensimbi angenamthungo ama-boiler anomfutho ophezulu asetshenziswa kakhulu kuma-header okuthutha uketshezi olushisa kakhulu nolunomfutho ophezulu kanye namapayipi ezitsheni zamandla kagesi kanye nasezitshalweni zamandla enuzi. Izinto ezimele yilezi20G, 12Cr1MoVG, 15CrMoG, njll.
Amapayipi ensimbi angenamthungo emishini yomanyolo enomfutho ophezulu asetshenziswa kakhulu ukuthutha amapayipi oketshezi anokushisa okuphezulu kanye nomfutho ophezulu emishinini yomanyolo. Izinto ezimele ziyi-20, 16Mn,12CrMo, 12Cr2Mo, njll.
Amapayipi ensimbi angenamthungo okuqhekeka uphethiloli asetshenziswa kakhulu kuma-boiler, kuma-heat exchanger kanye namapayipi okuthutha uketshezi ezitshalweni zokuncibilikisa uphethiloli. Izinto ezimele wona yi-20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, njll.
Amapayipi ensimbi angenamthungo amasilinda egesi asetshenziswa kakhulu ekwenzeni amasilinda egesi ahlukahlukene kanye negesi ye-hydraulic. Izinto ezimele wona yi-37Mn, 34Mn2V, 35CrMo, njll.
Amapayipi ensimbi angenamthungo ashiswayo asetshenziselwa izinto zokufaka amanzi, ezisetshenziswa kakhulu ekwenzeni izisekelo ze-hydraulic, amasilinda namakholomu ezimayini zamalahle, kanye namanye amasilinda namakholomu e-hydraulic. Izinto ezimele wona ziyi-20, 45, 27SiMn, njll.
Amapayipi ensimbi angenamthungo adonswa ngokubandayo noma aqiniswa ngokubandayo asetshenziswa kakhulu ezakhiweni zemishini kanye nemishini yokucindezela ikhabhoni, edinga ukunemba okuphezulu kanye nokuqedwa okuhle kwendawo. Izinto ezimele zihlanganisa insimbi engu-20, engu-45, njll.
Amapayipi ensimbi angenamthungo adonswa ngokubandayo kanye namapayipi ensimbi anomumo okhethekile asetshenziswa kakhulu ekwenzeni izingxenye nezingxenye ezahlukahlukene zesakhiwo. Enziwe ngensimbi yesakhiwo yekhabhoni esezingeni eliphezulu kanye nensimbi yesakhiwo engenangxubevange eningi.
Amapayipi ensimbi angenamthungo anobubanzi obuqondile bangaphakathi bamasilinda e-hydraulic kanye ne-pneumatic asetshenziswa kakhulu ukwenza amapayipi ensimbi angenamthungo adonswa ngokubandayo noma aqoqwe ngokubandayo anobubanzi obuqondile bangaphakathi bamasilinda e-hydraulic kanye ne-pneumatic. Izinto ezimele wona ziyinsimbi engu-20, engu-45, njll.
