Maopopo iā ʻoe e pili ana i nā paipu paila ʻole 20G a me SA-210C (25MnG)?

ʻO 20G kahi papa kila i helu ʻia ma GB/T5310 (e pili ana i nā helu haole: st45.8 ma Kelemānia, STB42 ma Iapana, SA106B ma ʻAmelika Hui Pū ʻIa), a ʻo ia ke kila hoʻohana maʻamau no nā paipu kila boiler. ʻO kona ʻano kemika a me nā waiwai mechanical he mea like ia me nā papa 20. Keia kila i kekahi lumi wela a me ka medium kiʻekiʻe wela ikaika, haʻahaʻa kalapona maʻiʻo, maikaʻi plasticity a me ka toughness, a me ka maikai anu a me ka wela hana a me ka welding performance.It ua nui hoʻohana 'ia no ka hana boiler pono me ke kiʻekiʻe puʻe a me nā palena kiʻekiʻe, superheaters a me reheaters i loko. ʻo ka ʻāpana haʻahaʻa haʻahaʻa, economizers, a me nā paia i hoʻoluʻu wai; No ka laʻana, hoʻohana ʻia nā paipu anawaena liʻiliʻi e like me nā paipu wela wela me ka mahana o ka paia o ≤ 500 ℃, a me nā paipu pā hoʻoluʻu wai a me nā paipu economizer. Ma muli o ka graphitization i hoʻokumu ʻia e ka hana lōʻihi o ke kila kalapona ma luna o 450 ℃, ʻoi aku ka maikaʻi o ka kaupalena ʻana i ka mahana hana lōʻihi lōʻihi o nā paipu e like me ka wela wela ma lalo o 450 ℃. Hiki i kēia kila ke hoʻokō i nā koi o nā superheaters a me nā pipelines i loko o kēia ʻano wela ma ke ʻano o ka ikaika, a loaʻa iā ia ke kūpaʻa oxidation maikaʻi, ka plasticity maikaʻi, ka paʻakikī, ka hana kuʻi ʻana a me nā mea ʻē aʻe ke anuanu a me ka wela, e hoʻohana nui ʻia.

ʻO SA-210C (25MnG) he kila kila ma ke kūlana ASME SA-210. He paipu kila manganese kalapona liʻiliʻi i hoʻohana ʻia i loko o nā boilers a me nā superheaters, a me ke ʻano pearlescent ʻano kila ikaika kiʻekiʻe. He mea maʻalahi ke kaʻina hana o kēia kila, a maikaʻi kāna hana hana anu a me ka wela. Hiki ke hoʻololi i ka 20G me ia e hoʻemi i ka mānoanoa o nā paia lahilahi, e hoʻemi i ka hoʻohana ʻana i nā mea waiwai, a hoʻomaikaʻi hoʻi i ke kūlana hoʻololi wela o nā paila.

ʻO kona wahi hoʻohana a me ka mahana he mea like ia me 20G, hoʻohana nui ʻia no nā pā wai hoʻoluʻu, economizers, superheaters haʻahaʻa haʻahaʻa a me nā mea ʻē aʻe me nā mahana hana ma lalo o 500 ℃.

Hana nui ʻo Shandong Kungang Metal Technology Co., Ltd. i nā huahana paipu kila. Hoʻohana pinepine ʻia ʻo 20G a me SA-210C i nā mea maʻamau i nā hale kūʻai, a hiki ke hana ʻia nā kikoʻī kūikawā e like me nā koi o ka mea kūʻai aku. Hana ʻia ka huahana me ke kila kiʻekiʻe, a ʻo nā mea hōʻailona kino a me nā kemika e kū i nā kūlana aupuni. Ua kaulana ka huahana ma ka home a ma ka honua. Manaʻo mākou i kāu kūkākūkā!
