Nā Māhele Huahana

ʻO ka haku mele: 22% chromium, 5% nickel, 3% molybdenum, a me 0.18% nitrogen. Mechanical waiwai: Tensile ikaika: 620MPa, Hua ikaika: 450MPa, Elongation: 25%.

He kūpono loa ka 310S stainless steel no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe, no ka laʻana i nā noi e like me nā kapuahi hoʻomaʻamaʻa wela, nā keʻena puhi, nā paila, nā mea kemika, nā mea hoʻololi wela, a me nā paipu umu.

Hoʻohui: 409 stainless steel he austenitic stainless steel me ka chromium kiʻekiʻe (e pili ana i 10.5-11.7%) a me ka haʻahaʻa kalapona.

ʻO 904L he kila kila kila nui loa me ka pale ʻana i ka corrosion kiʻekiʻe loa, ʻoi aku hoʻi ma nā wahi i loaʻa nā ion chloride. Aia kēia mea i ka nickel kiʻekiʻe a me ka molybdenum maʻiʻo, a me ka liʻiliʻi o ke keleawe, e hāʻawi iā ia i ka maikaʻi o ka corrosion kū'ē i ka acidic, alkaline, a me ka paʻakai.

ʻO Hastelloy C-276 kahi mea hao i hoʻokumu ʻia i ka nickel i loaʻa nā mea e like me ka molybdenum, chromium a me tungsten, e hāʻawi ana iā ia i ka pale ʻana i ka corrosion maikaʻi loa i nā ʻano pōʻino kino, kūpono loa no ka hoʻohana ʻana i nā kaiapuni i loaʻa ka chloride. ʻO S32760 (Ai ʻike ʻia ʻo Super Dual-phase Steel 2507) he kila kila ʻelua-phase e hoʻohui i nā pono o ka austenite a me ka ferric body stainless steel, me ka ikaika kiʻekiʻe a ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion a me ka pale corrosion.

ʻO ka hui kemika: ʻO Incoloy 800 he nickel-iron-chromium alloy i loaʻa i kahi kiʻekiʻe o ka nickel (e pili ana i 30-35%), chromium (e pili ana i 19-23%) a me ka hao (e pili ana i 39-45%).

TP304L ʻO ka paipu paipu o 304L stainless steel, he haʻahaʻa-carbon austenitic stainless steel, nona ka maʻamau ASTM A312. ʻO ka 304L stainless steel he haʻahaʻa haʻahaʻa haʻahaʻa o ka 304 stainless steel, a ua hoʻomaluʻia kona kinona kalapona ma lalo o 0.03%, e hāʻawi ana i ka maikaʻi o ke kū'ēʻana o ka corrosion intercrystalline i ka wā welding.304L stainless steel ka mea i hoʻohana nuiʻia i nā noi e koi ana i ke kū'ēʻana a me ke kiʻekiʻe o ka wela, e like me ke kemika, ka aila, ka meaʻai a me ka ikehu lāʻau.

TP304 he austenitic stainless steel nona ka 300 series stainless steel a hoʻohana nui ʻia i nā ʻoihana ʻoihana, ʻoi aku hoʻi i nā noi e koi ana i ke kūpaʻa corrosion a me ke kūpaʻa wela kiʻekiʻe. Loaʻa i ka TP 304 stainless steel ka 18% chromium a me 8% nickel, e hāʻawi iā ia i ka pale corrosion maikaʻi a me nā waiwai mechanical maikaʻi. Hoʻohana nui ʻia ka paipu welded o TP 304 stainless steel i ka ʻoihana e lawe i ka wai, ke kinoea a me ka mahu, a me nā mea hana i loko o ke kemika, ka aila, ka hoʻoili ʻana i nā meaʻai, nā lāʻau lapaʻau a me nā ʻoihana nuklea.

TP317H ʻO ke kaʻina hana o nā paipu wiliwili kila kila e pili ana i nā ʻanuʻu he nui e hōʻoia i ka maikaʻi o ka huahana hope e hoʻokō i nā kūlana ʻoihana kūikawā a me nā koi noi.

ʻO TP347H ʻO ke kila kila kila he mea kila austenitic kūikawā, aia ia i ka pūʻulu kila ikaika wela, me ke kūpaʻa wela maikaʻi a me ke kūpaʻa intercrystalline corrosion. He mea kūpono loa kēia mea no ka hoʻohana ʻana i nā wela kiʻekiʻe, e like me nā paipu superheater boiler, nā paipu hoʻoheheʻe hou, nā paipu mahu, a me nā mea hoʻololi wela petrochemical. TP347H ʻO ka hana kuʻi ʻana maikaʻi o ka paipu welded stainless steel, hiki iā ia ke mālama i ka pono o ka waiwai a me ka pale ʻana i ka corrosion i ka wā o ke kaʻina hana.

He ʻano paipu hoʻohana ʻia i nā mea hoʻololi wela. Hanaʻia ia me ke kila kila a he maikaʻi ke kū'ēʻana i ka corrosion, ke kiʻekiʻe o ka mahana wela a me ka ikaika mechanical.Stainless steel heat transfer pipes ua hoʻohana nuiʻia i ka kemika, ka aila, ka meaʻai, ka lāʻau lapaʻau, ka ikehu, ka mīkini, ka aerospace a me nāʻoihana'ē aʻe e hoʻololi i ka wela a hoʻonui i ka maikaʻi o ka hoʻololi wela.

ʻO nā paipu kila kila e pili ana i nā paipu paipu likeʻole i hanaʻia i nā mea kila kila, i hoʻohana nuiʻia i nāʻoihanaʻoihana a me nā kīvila.
