Amapayipi ensimbi angenamthungo okuthutha uketshezi asetshenziswa kakhulu ekuthuthweni kwamapayipi oketshezi kwezobunjiniyela kanye nemishini emikhulu. Izinto ezimele (amamaki) yi-20, Q345, njll.

Amapayipi ensimbi angenamthungo okucindezela okuphansi nokuphakathiamabhoyilazisetshenziswa kakhulu kumapayipi athutha uketshezi oluphansi noluphakathi kuma-boiler ezimboni kanye nama-boiler asekhaya. Izinto ezimele ziyinsimbi engu-10 no-20.

Amapayipi ensimbi angenamthungoamabhoyila anomfutho ophezuluzisetshenziswa kakhulu kuma-header kanye namapayipi okuthutha uketshezi olushisa kakhulu nolunomfutho ophezulu ezitsheni zamandla kagesi kanye nasezitsheni zamandla enuzi. Izinto ezimele ziyi-20G, 12Cr1MoVG, 15CrMoG, njll.

Amapayipi ensimbi angenamthungoumanyolo ocindezela kakhuluimishini isetshenziswa kakhulu ukuthutha amapayipi oketshezi ashisa kakhulu futhi anomfutho ophezulu ngemishini kamanyolo. 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-15mog, 15CrMoG, 12crmog, 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.
