Nānā o ka paipu kila kila
Hoʻohana ʻia kahi Alloy Steel Pipe i nā noi e koi ana i nā waiwai kūpaʻa corrosion me ka paʻa maikaʻi a me ke kumu kūʻai. No ka ʻōlelo maʻalahi, ʻoi aku ka maikaʻi o nā paipu huila ma kēlā mau wahi kahi e hāʻule ai nā paipu kila kalapona. ʻElua mau papa o nā kila kila - nā kila kiʻekiʻe a me nā kila haʻahaʻa. ʻO nā paipu i hoʻokumu ʻia i nā mea hao hao haʻahaʻa loaʻa kahi mea hoʻohuihui ma lalo o 5%. ʻOiai ʻo ka mea i hoʻohuihui ʻia o ke kila kila kiʻekiʻe ma waena o 5% a ma kahi o 50%. E like me ka hapa nui o nā alloys, ʻoi aku ka kiʻekiʻe o ka puʻe hana o kahi Alloy Steel Seamless Pipe ma kahi o 20% kiʻekiʻe ma mua o kahi paipu welded. No laila, i nā noi i ʻoi aku ka kiʻekiʻe o ka hana ma ke ʻano he koi, ʻae ʻia ka hoʻohana ʻana i kahi paipu seamless. ʻOiai ʻoi aku ka ikaika ma mua o ka paipu welded, ʻoi aku ka kiʻekiʻe o ke kumukūʻai. Eia kekahi, ʻoi aku ka nui o ka hopena o ka corrosion intergranular ma ka weld zone i hoʻopili ʻia i loko o kahi huahana welded. ʻO ka ʻokoʻa i ʻike ʻia ma waena o kahi Alloy Steel Welded Pipe 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 kuʻina i loaʻa ma ka Alloy Steel ERW Pipe ma ke ʻano o ka mālama ʻana i ka ʻili, i ʻike ʻole ʻia e nā maka kanaka.
