GB5310ʻo ia ke code maʻamau o ke kūlana aupuni Kina "Seamless Steel Pipes forNā Boiler Kaomi Kiʻekiʻe", e wehewehe ana i nā koi loea no nā paipu kila humuhumu no nā paila kiʻekiʻe a me nā paipu mahu. Uhi ka maʻamau GB5310 i nā ʻano kila like ʻole e hoʻokō i nā pono noi like ʻole. Eia kekahi mau papa maʻamau a me kā lākou ʻoihana noi:

20GʻO 20G kekahi o nā papa i hoʻohana nui ʻia ma GB5310, me nā ʻāpana nui o ke kalapona, manganese a me ka silicon. Loaʻa iā ia nā waiwai mechanical piha maikaʻi a me nā waiwai hoʻoheheʻe, a hoʻohana nui ʻia e hana i nā ʻāpana koʻikoʻi e like me nā paia i hoʻomaʻalili ʻia i ka wai, nā superheaters, nā economizers a me nā pahu i loko o nā paila kikowaena mana.

15CrMoGAia i loko o kēia kila ka chromium a me ka molybdenum, a he ikaika kiʻekiʻe kona i ka mahana kiʻekiʻe a me ke kūpaʻa ʻana i ka oxidation. Hoʻohana pinepine ʻia nā paipu kila seamless 15CrMoG e hana i nā paipu mahu wela kiʻekiʻe a me ke kaomi kiʻekiʻe, nā poʻomanaʻo a me nā conduits, a pēlā aku, a hoʻohana nui ʻia i nā ʻoihana petrochemical a me ka mana.

12Cr1MoVGLoaʻa i loko nā mea chromium kiʻekiʻe, molybdenum a me vanadium, me ka hana wela kiʻekiʻe maikaʻi loa a me ke kūpaʻa lōʻihi. Hoʻohana pinepine ʻia nā paipu kila humuhumu o kēia papa i nā paila wela kiʻekiʻe a me ke kaomi kiʻekiʻe a me nā lako mana nukelea, ʻoiai nā mea hoʻololi wela, nā paipu mahu, a pēlā aku.

Hoʻohana nui ʻia kēia mau papa like ʻole o nā paipu kila humuhumu ʻole i ka hana ʻana i nā ʻāpana koʻikoʻi i nā wahi wela kiʻekiʻe a me ke kaomi kiʻekiʻe e like me ka mana, ka petrochemical, a me ka mana nukelea ma muli o kā lākou ʻano kemika kūikawā a me nā waiwai mechanical. Ma ke koho ʻana i ke papa kila kūpono, hiki ke hōʻoia ʻia ka palekana a me ke kūpaʻa o nā lako ma lalo o nā kūlana hana koʻikoʻi, a hiki ke hoʻolōʻihi ʻia ke ola lawelawe.
