ʻO nā lepa hao kalapona VS nā lepa kila kila

ʻO ke kila kalapona he mea hao-carbon i loaʻa ka ʻoi aku ka nui o ke kalapona a me ka helu heheʻe haʻahaʻa ma mua o ke kila kila. Ua like ke kila kalapona i ka helehelena a me ka waiwai i ke kila kuhiliʻole, akā ʻoi aku ka nui o ke kalapona.

Hoʻohana pinepine ʻia ka ʻenekinia a me nā mea hana e like me ke kila kalapona i nā kaʻina hana ʻoihana nui, e like me ke kelepona, ka lawe ʻana, ka hana kemika, a me ka ʻili a me ka hoʻomaʻemaʻe ʻana.

Nui nā ʻano kila i hiki ke kapa ʻia ʻo 304 stainless steel flanges, akā ʻo nā ʻano kila āpau i hana maoli ʻia mai ka hao a me ke kalapona me ka hoʻohana ʻana i kahi kaʻina hana ʻelua. Ke hoʻohui ʻia ka chromium a me ka nickel i ke kila kila, loaʻa ke kūpaʻa corrosion.

KA ʻOkoʻa ma waena o nā ʻaʻa hao kalapona a me nā ʻala hao ʻole.
ʻO nā mea hoʻoheheʻe i hana ʻia mai nā māka A-105 ka mea mua a maʻamau i hoʻohana ʻia e hana i nā flanges paipu. No nā noi e koi ana i nā mahana haʻahaʻa, hoʻohana ʻia nā māka A-350 LF2, aʻo nā māka A-694, F42-F70, ua hoʻolālā ʻia no nā hua kiʻekiʻe. Ma muli o ka hoʻonui ʻana i ka ikaika o nā flanges kila kalapona, hoʻohana nui ʻia nā mea kiʻekiʻe i nā noi pipeline.

Ma waho aʻe o ka loaʻa ʻana o ka chromium a me ka molybdenum ma mua o nā flanges kila kalapona, ua hoʻolālā ʻia nā flanges kila kila e kū i ka wela kiʻekiʻe a me nā kaiapuni kiʻekiʻe. Ma muli o ka hoʻonui ʻia ʻana o ka chromium, ʻoi aku ka ikaika o ka pale corrosion ma mua o nā flanges carbon steel maʻamau.

ʻO ke kila kila i loaʻa ka nickel, chromium a me ka molybdenum ka lua o ka hoʻohana pinepine ʻana i nā mea forging i ka hana flange. Loaʻa ka mea maʻamau ASTM A182-F304 / F304L a me A182-F316 / F316L forgings ma ka moʻo A182-F300/F400. Hiki ke hoʻohui ʻia nā mea trace i ka wā o ka hoʻoheheʻe ʻana e hoʻokō i nā pono lawelawe o kēia mau papa forging. Eia kekahi, ʻaʻole magnetik ka moʻo 300 aʻo ka moʻo 400 he mau waiwai magnetic a ʻoi aku ka liʻiliʻi o ka corrosion.
