ʻO TP316L ʻO ke kila kila kila he ʻano mea kila kuhili ʻole austenitic, aia ia i ka moʻo 316, kahi i hōʻike ʻia ai ka "L" i ke kalapona haʻahaʻa (Low Carbon). He kūpono loa kēia mea no ka hoʻohana ʻana i nā kūlana e koi ʻia ai ka wili ma muli o kāna mau waiwai wili maikaʻi a me ke kūpaʻa corrosion. Hoʻohana nui ʻia ʻo TP316L Stainless steel welded pipe i ka ʻoihana kemika, ka ʻaila, ka hana meaʻai, ka lāʻau lapaʻau, ka hana pepa, ka ʻenehana moana a me nā ʻoihana ʻē aʻe.

ʻO TP316Ti Stainless steel welded pipe he mea austenitic stainless steel, nona ka 316 series, aia ka titanium ma ke ʻano he mea hoʻokū. He mea kūpono loa kēia mea no ka hoʻohana ʻana i nā kaiapuni kiʻekiʻe a me nā corrosive, e like me ke kemika, ka ʻaila, ka hoʻoili ʻana i ka meaʻai, ka lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe. TP316Ti ʻO ka titanium stabilization o ke kila kila welded paipu e kōkua i ka pale ʻana i ka intercrystalline corrosion, ʻo ia ke kumu o ka pilina ikaika o ka titanium a me ke kalapona, a me ka hui pū ʻana me ke kalapona e hana i ka titanium carbide paʻa, i mea e pale ai i ke kūkulu ʻia ʻana o ka chromium carbide ma ka palena o ka palaoa a pale i ka pale ʻana o ka mea.

ʻO 15X25T he kila kila, "15" kahi kalapona ma kahi o 0.15%, "X" e hōʻike ana i ka ʻike o nā mea hoʻohuihui, a ʻo "25 T" e hōʻike ana he 25% o nā mea hoʻohuihui. Ma ke kūlana Lūkini, pili kēia ʻano kila i ka ʻāpana o ke kila structural alloy a hoʻohana maʻamau ʻia e hana i nā ʻāpana mechanical e kū i nā ukana kiʻekiʻe a me nā hopena.

Anti-intercrystalline corrosion: Ma muli o ka hoʻohui ʻana o ka titanium, hiki i ka TP 321 stainless steel welded pipe ke pale aku i ka corrosion intercrystalline, ma muli o ka pili ikaika o ka titanium a me ke kalapona, i hui pū ʻia me ke kalapona e hana i kahi carbide titanium paʻa, pēlā e pale ai i ka hoʻokumu ʻia ʻana o ka chromium carbide, a me ka pale ʻana i ka mea aniani.

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.
