ʻO ka hana ʻana a me ka hana ʻana o ka paipu hoʻoheheʻe Petroleum:

① ʻO ka maʻamau, ʻo ka wela o ka lawelawe o nā paipu kila ma lalo o 450 ° C. ʻO nā paipu home ka mea nui i hana ʻia me ka No. 10, No. 20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, nā paipu ʻōwili wela a i ʻole nā ​​paipu huki anu.

② Hōʻike pinepine ʻia nā paipu kila maʻamau GB9948 i ka wela kiʻekiʻe a me nā kūlana kiʻekiʻe ke hoʻohana ʻia. ʻO nā paipu e oxidize a corrode ma lalo o ka hana o ke kinoea flue wela kiʻekiʻe a me ka mahu wai. Pono nā paipu kila e loaʻa ka ikaika mau loa, ke kūpaʻa kiʻekiʻe i ka oxidation a me ka corrosion, a me ke kūpaʻa maikaʻi.

hoʻohana:

① ʻO ka maʻamau, hoʻohana nui ʻia nā paipu kila maʻemaʻe e hana i nā paipu pā wai, nā paipu wai paila, nā paipu mokumahu wela, nā paipu mahu no nā locomotive boilers, nā paipu uahi nui a liʻiliʻi a me nā paipu brick arch, etc.

②GB9948 paipu kila maʻemaʻe ʻole i hoʻohana nui ʻia no ka hana ʻana i nā paipu superheater, nā paipu reheater, nā paipu alakaʻi ea, nā paipu mahu nui, etc.

ʻO GB9948 mau paipu kila maʻamau i hoʻokaʻawale ʻia i nā paipu boiler maʻamau a me nā paipu paila kiʻekiʻe e like me kā lākou hana wela kiʻekiʻe. ʻO nā paipu boiler maʻamau a i ʻole nā ​​​​paipu paila kiʻekiʻe, hiki ke hoʻokaʻawale ʻia i nā paipu kila like ʻole e like me kā lākou koi hoʻohana like ʻole.
