ʻO wai nā paipu kila e hiki ke wehewehe ʻia he mau paipu hao hao haʻahaʻa?

Ma waena o nā paipu kila kila, inā hiki ke hoʻohui ʻia nā mea hoʻohui e like me nickel, chromium a me ka nui o ka molybdenum alloy content mai ka 2.07% a hiki i nā pae ma lalo koke o nā kila kuhili ʻole, aia ka liʻiliʻi o 10% Cr, ua wehewehe ʻia lākou he mau kila haʻahaʻa.

• Chromium-molybdenum paipu kila

ʻO kēia pūʻulu o ke kila kila haʻahaʻa he 0.5% a 9% Cr a me 0.5% a 1% Mo. ʻO ka maʻamau kalapona ma lalo o 0.20%.Hoʻonui ka ʻike Cr i kāna mau anti-oxidation a me ka anti-corrosion hiki, a hoʻonui ʻo Mo i kona kūpaʻa ma lalo o nā kūlana wela kiʻekiʻe;Hoʻopau pinepine ʻia nā kūlana lako kila ma o ka annealing a i ʻole ka hoʻohālikelike a me nā kaʻina hana.Ua hoʻohana nui ʻia nā paipu kila kila Chromium-molybdenum i ka ʻoihana ʻaila a me ke kinoea, nā mea kanu mana a me nā noi wela kiʻekiʻe.
