No ka paipu alloy A335, ʻo ka mākeke nui ʻo India. No ka mākeke ʻo India e pono pinepine iā IBR. i kēia lā e hōʻike iā IBR no ka kuhikuhi.
ʻO nā lula ʻo India Boiler Regulations (INDIA BOILER REGULATIONS, i kapa ʻia ʻo IBR) i ʻōlelo maopopo ʻia e pono e nānā ʻia nā boilers, nā ipu kaomi, nā paipu, nā valves, nā mea maka (nā papa, nā pahu, nā castings, forgings) i lawe ʻia i India e nānā ʻia e ka CBB ʻoihana nānā ʻae ʻia. Manaʻo nā mea nānā i ʻae ʻia i ka loiloi hoʻolālā a me ka nānā ʻana i ke kaʻina hana hana e like me IBR, a hana i ka nānā ʻana a me ka hoʻopaʻa inoa ʻana ma mua o ke komo ʻana i ka mākeke India. I ka manawa like, pono nā mea hana e hoʻopuka i nā ʻano IBR Forms e like me ka hana ʻana, hoʻonohonoho a me ka palapala hōʻoia e like me nā koi IBR. Hiki ke waiho ʻia ka ʻae ʻia ma hope o ke kau inoa ʻia ʻana e ke keʻena nānā i ʻae ʻia.
ʻO ka Indian Boiler Code e kuhikuhi pono ana i nā boilers a me nā moku kaomi i hana ʻia ma nā ʻāina ʻē aʻe ma India e pono e hana i ka nānā ʻana a me ka hōʻoia IBR, a pono e ʻae ʻia nā keʻena nānā ʻekolu e CBB. No laila, ʻo ka hala ʻana i ka palapala IBR he "passport" no ka hui e komo i ka mākeke India.
I kēia manawa, ʻo nā papahana o nā ʻoihana ʻenekinia home ma India ka mea nui i hoʻolako ponoʻia i nā mea kanu alumini electrolytic, a komo pū nā ʻoihana hoʻopukapuka. ʻO nā huahana e pili ana i nā moku kaomi ʻo ia ka mea nui: nā papahana mana wela, ʻaelike nui EPC no nā hui ʻenekinia; ka hoʻokuʻu pololei ʻana i nā boilers, turbines steam, auxiliary station station, etc.; kekahi mau moku kaomi i hoʻohana ʻia i nā ʻoihana petrochemical; nā kiwi, nā paipu a me nā mea ʻē aʻe; nā paipu kila, nā pā kila a me nā mea waiwai ʻē aʻe.
Me ke kōkua o ka ʻoihana waiwai ʻoihana hōʻoia, hiki i ka Yunquan Testing ke hāʻawi i nā lawelawe nānā e pili ana i ka IBR, ka hoʻomaʻamaʻa maʻamau, ka hoʻomaʻamaʻa limahana, ke kūkākūkā ʻenehana a me ka loiloi, ka hōʻoia welder e pili ana i ka IBR a me ke kaʻina hana accreditation lawelawe, a me ka hoʻopuka e pili ana i ka hoʻokō ʻana me ka CBB ʻae ʻia ka ʻoihana nānā. Nā palapala hōʻoia, no ka laʻana, palapala FORM, palapala welder IBR, etc.
