Paipu paila
ʻO nā paipu paila kekahi o ka paipu ʻole.ʻO nā ʻano hana hana like me ka seamless tube, akā aia nā koi koʻikoʻi no ka hana ʻana i nā paipu kila.E like me ka pae wela, ua māhele ʻia ka pahu boiler i nā paipu paila maʻamau a me nā paipu paila kiʻekiʻe.
Nā hana hana:
① ma lalo o 450 ℃ ka mahana wela o ka paila paila, me ka hoʻohana ʻana i ka paipu wela a i ʻole ka paipu hao huki ʻia.
② hoʻohana pinepine ʻia ka paipu paila kiʻekiʻe i nā kūlana o ka wela kiʻekiʻe a me ka paipu kiʻekiʻe kiʻekiʻe, ka hopena o ke kinoea flue wela kiʻekiʻe a me ka mahu wai, oxidation a me ka corrosion.ʻO ka paipu kila me ka ikaika rupture kiʻekiʻe, ke kūpaʻa kiʻekiʻe i ka corrosion oxygen a loaʻa ka paʻa hoʻonohonoho maikaʻi.
Nā kumu o nā paipu paila:
① Hoʻohana nui ʻia nā paipu paila maʻamau no ka hana ʻana i nā paipu pā wai, nā paipu i loko o ka wai paila a me ka paipu mokumahu wela nui, nā paipu paila locomotive wela nui, ka paipu uahi nui a me ka liʻiliʻi a me ka paipu paipu.
② kiʻekiʻe-pressure boiler tube ua hoʻohana nui ʻia e hana i ke kiʻekiʻe kiʻekiʻe a me ka ultra-high pressure boiler super heat tubes, reheat tubes, ea, ka paipu mahu nui.
Māhele:
Hōʻike ʻia nā paipu paila maʻamau a me nā paipu paila paila kiʻekiʻe i ka hana wela kiʻekiʻe.Hiki ke hoʻokaʻawale ʻia nā paipu paila ma ke ʻano nui, a i ʻole kiʻekiʻe-pressure boiler tubes e like me kā lākou hoʻohana ʻana i nā ʻano paipu kila.
Loaʻa nā kūlana a me nā mea no ka paipu kila ma ke kalapona, ka hao, a me ke kila kila.
Ke kila kalapona:ASTM/ASME A/SA 106, ASTM A179, ASTM A192, ASTM/ASME A/SA 210, ASTM A333 Gr 1, 6,7 a i Gr 9,
kila kila:ASTM/ASME A/SA 213 T1, T2, T5, T9, T11, T12, T22, T91, T92;ASTM A335 P1, P2, P5, P9, P11, P12, P22, P91, P92
Kila kohu ʻole:ASTM A268, ASTM A213, TP304/L, TP316/L, 310S, 309S, 317,317L, 321,321H, a me nā mea kila kuhiliʻole duplex etc.
Nui maʻamau: OD mai 6mm a 1240mm, mānoanoa mai 1mm a 50mm
Nā ʻano:ʻO ka paila paila pololei, a me ka paipu kila U no ka puʻupuʻu hoʻololi.
Hōʻike kēia mau kūlana i ka hoʻokaʻawale ʻana, ka nui, ke ʻano, ke kaumaha a me ka ʻae ʻia ʻana, nā koi ʻenehana, ka nānā ʻana a me ka hoʻāʻo ʻana, ka hōʻailona, ka hōʻailona a me ka palapala hōʻoia maikaʻi o nā paipu kila seamless no ka paila.
