Kiʻekiʻe puʻe boiler paipu mea hana maoli wahi

ʻO ka paipu paila kekahi ʻano o ka paipu ʻole. ʻO keʻano o ka hanaʻana ua like ia me ka paipuʻole, akā aia nā koi koʻikoʻi no ka pae kila i hoʻohanaʻia i ka hanaʻana i ka paipu kila. Wahi a ka wela o ka lawelawe, ua māhele ʻia ia i loko o ka paila paila maʻamau a me ka paipu paila kiʻekiʻe.

ʻO ka waiwai mechanical o ka paila paila he mea nui ia e hōʻoia i ka hana hope loa (mechanical property) o ke kila, e hilinaʻi ana i ka hoʻohui kemika a me ka ʻōnaehana mālama wela o ke kila. I ke kūlana paipu kila, e like me nā koi lawelawe like ʻole, ʻike ʻia nā waiwai tensile (ikaika tensile, ikaika hua a i ʻole yield point, elongation), paʻakikī a paʻakikī, a me nā waiwai kiʻekiʻe a haʻahaʻa e koi ʻia e nā mea hoʻohana.

① ʻO ka maʻamau, ʻoi aku ka mahana o ka lawelawe o nā paipu paila ma lalo o 350 ℃, a ʻo nā paipu hale i hana nui ʻia me ka No. 10 a me ka No.

②Loaʻa pinepine nā paipu paila kiʻekiʻe i ka wela kiʻekiʻe a me nā kūlana kiʻekiʻe. E oxidized a corroded nā paipu ma lalo o ka hana o ke kinoea a me ka mahu. Pono ka paipu kila e loaʻa ka ikaika mau loa, ka anti-oxidation kiʻekiʻe a me ka hana corrosion a me ka paʻa paʻa maikaʻi.

① Hoʻohana nui ʻia nā paipu paila maʻamau no ka hana ʻana i nā paipu pā wai, nā paipu wai e hoʻolapalapa ai, nā paipu mahu superheated, nā pahu mahu no nā locomotive boilers, nā paipu uahi nui a liʻiliʻi a me nā paipu brick arch.

②Hoʻohana nui ʻia nā paipu paila kiʻekiʻe no ka hana ʻana i nā paipu superheater, nā paipu reheater, nā ʻea ea, nā pahu mahu nui, etc. ʻO ka hāʻawi ʻana a me ke koi ʻana o ka ʻoihana pahu boiler piʻi kiʻekiʻe e paʻa mau, akā e hoʻokaʻawale ʻia ke kūlana hāʻawi a me ke koi o kēlā me kēia ʻoihana kikoʻī. Hōʻike ka poʻe Insiders ʻo ka loulou koʻikoʻi ka hoʻohana ʻana a me ka hoʻolaha ʻana i ka hoʻopakele ikehu hou a me ka insulation thermal 20g kiʻekiʻe-pressure boiler tube lako.

Ke hoʻonui mālie nei nā huahana hou o ka ikehu hou 20g kiʻekiʻe-pressure boiler tube i loko o ka mākeke, e like me nā uhi pale ʻōmaʻomaʻo, mālama i ka ikehu a me ka wai hoʻomaʻemaʻe wai, nā pōhaku palekana kaiapuni, ka mālama ʻana i ke kaiapuni waho cement foam insulation board, etc. ʻO ka manaʻolana o ka mālama ʻana i ka ikehu a me nā huahana mālama kaiapuni i ka mākeke ākea o 20g kiʻekiʻe-pressure boiler tube ʻoihana e hoʻohiki nei [1]
