Paipu kila kila ASTM A335 42CRMO

Hoʻohana ʻia kahi Paipu Kila Alloy i nā noi e koi ana i nā waiwai kūpaʻa i ka palaho me ka lōʻihi maikaʻi a me ke kumukūʻai hoʻokele waiwai. I ka ʻōlelo maʻalahi, makemake ʻia nā paipu alloy ma kēlā mau wahi kahi e hāʻule ai nā paipu kila kalapona. ʻElua mau papa o nā kila alloy - nā alloys kiʻekiʻe a me nā kila alloy haʻahaʻa. ʻO nā paipu i hana i nā kila alloy haʻahaʻa he ʻike alloying ma lalo o 5%. ʻOiai ʻo ka ʻike alloying o ke kila alloy kiʻekiʻe e kū ana ma waena o 5% a i kahi 50%. E like me ka hapa nui o nā alloys, ʻo ka hiki ke kaomi hana o kahi Paipu Seamless Kila Alloy ma kahi o 20% kiʻekiʻe ma mua o ka paipu welded. No laila, i nā noi i loaʻa ke kaomi hana kiʻekiʻe ma ke ʻano he koi mua, ua kūpono ka hoʻohana ʻana i kahi paipu seamless. ʻOiai ʻoi aku ka ikaika ma mua o ka paipu welded, ʻoi aku ke kiʻekiʻe o ke kumukūʻai. Eia kekahi, ʻoi aku ka nui o ka pilikia o ka corrosion intergranular ma ka ʻāpana weld i hoʻopilikia ʻia e ka wela i kahi huahana welded. ʻO ka ʻokoʻa i ʻike ʻia ma waena o kahi Paipu Welded Kila Alloy a me kahi huahana seamless ʻo ia ka latitudinal seam ma ka lōʻihi o ka paipu. Eia nō naʻe, i kēia lā, me ka holomua o ka ʻenehana, hiki ke hoʻemi nui ʻia ke humuhumu i kau ʻia ma ka Alloy Steel ERW Pipe ma o ke ʻano o ka mālama ʻana i ka ʻili, i ʻike ʻole ʻia e nā maka kanaka.
