Ipayipi lensimbi elingenamthungoI-ASTM A335 P5iyipayipi elinamandla, elinamandla okushisa aphezulu elisetshenziswa kakhulu kuma-boilers anengcindezi ephezulu, ama-ultra-high-pressure kanye nezinhlelo zamapayipi ku-petroleum, amakhemikhali, amandla kagesi nakwezinye izimboni. Ipayipi lensimbi linezici ezinhle kakhulu zemishini nokumelana nokushisa, lingasebenza ngokuzinzile ngaphansi kwezinga lokushisa eliphezulu kanye nezindawo zokucindezela okukhulu, futhi ingenye yezinto ezibalulekile ezibalulekile emkhakheni wezimboni.

I-ASTM A335 P5ipayipi lensimbi lamukela ubuchwepheshe bokukhiqiza obungenamthungo ukuze kuqinisekiswe ukufana nokuvumelana kwepayipi, linokumelana nokugqwala okuhle nokumelana ne-oxidation, futhi lingasetshenziswa ezindaweni ezinokhahlo isikhathi eside ngaphandle kokwehluleka. Izakhi zayo eziyinhloko ze-alloying zihlanganisa i-chromium, i-molybdenum ne-tungsten, ehlinzeka ngokumelana nokushisa okuhle kakhulu kanye nokumelana ne-oxidation, okwenza ukuthi yenze kahle ngaphansi kwezimo zokushisa eziphezulu.

Izindawo zokufaka izicelo zimboza izikhungo ezisezingeni eliphezulu nezinomfutho ophezulu njengokukhipha uwoyela, okokusebenza kwamakhemikhali, amabhayela eziteshi zikagesi, nezimboni zamandla enuzi. Ipayipi lensimbi elingenamthungoI-ASTM A335 P5ayisetshenziswa kabanzi kuphela kumaphrojekthi amasha, kodwa futhi ivame ukusetshenziswa ekugcinweni nasekuvuselelweni kwezindawo ezikhona, okuhlinzeka ngesiqinisekiso esinokwethenjelwa sokuzinza okuqhubekayo kokukhiqizwa kwezimboni.
