GB/T5310ʻO nā paipu kila humuhumu maʻamau he mau huahana kiʻekiʻe i hoʻolālā ʻia no nā paipu paila mahu me ke kaomi kiʻekiʻe a ma luna. Hana ʻia lākou me ke kila kila kalapona kiʻekiʻe a me nā mea kila kila alloy e hōʻoia i kā lākou hana maikaʻi loa a me ka hilinaʻi i nā wahi mahana kiʻekiʻe a me ke kaomi kiʻekiʻe. Hoʻohana nui ʻia kēia paipu kila humuhumu i ka hana ʻana i nā paipu paila a me nā mea hoʻololi wela, e hāʻawi ana i kahi hōʻoia paʻa no ka hana ʻoihana.

Nā papa nui

GB/T5310ʻO nā paipu kila maʻamau maʻamau i hana nui ʻia me ka hui Cr-Mo a me ka hui Mn, a ʻo nā māka nui e komo pū ana20G, 20Mg, 20MoG, 12CrMoG, a pēlā aku. Loaʻa i kēia mau mea ka ikaika wela kiʻekiʻe a me ke kūpaʻa ʻana i ka oxidation, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma nā wahi hana ʻino me ka ʻole o ka hemahema. I waena o lākou:

20GHe kila hoʻolālā kalapona kiʻekiʻe me ka plasticity maikaʻi a me ka paʻakikī, i hoʻohana pinepine ʻia i nā paipu paila waena a me ke kaomi haʻahaʻa.
20Mg: ʻO ka hoʻohui ʻana i ka manganese i 20G e hoʻomaikaʻi hou aku i ka ikaika a me ka paʻakikī o ka mea, kūpono no nā paipu paila waena a me ke kiʻekiʻe.
20MoG: Hoʻohui ʻia ʻo Molybdenum i 20G, kahi e hoʻomaikaʻi nui ai i ke kūpaʻa wela a me ke kūpaʻa kolo, a kūpono hoʻi no nā paipu paila kiʻekiʻe.
12CrMoG: Ke kila kila i hana ʻia me ka chromium a me ka molybdenum, me ke kūpaʻa maikaʻi loa i ka oxidation wela kiʻekiʻe a me ka ikaika wela kiʻekiʻe, kūpono no nā paipu paila kaomi kiʻekiʻe loa.
Nā papa kila kūkulu alloy

ʻO nā papa kila kila hoʻonohonoho o nā paipu kila maʻamau GB/T5310 e komo pū ana me 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, a pēlā aku. Loaʻa i kēia mau papa o nā paipu kila nā ʻano mechanical like ʻole a me nā pae kūpono e like me nā ʻano kemika like ʻole a me nā kaʻina hana mālama wela:

15MoG a me 20MoG: ʻO ka hoʻohui ʻana o kahi nui kūpono o ka molybdenum e hoʻomaikaʻi nui i ka ikaika wela kiʻekiʻe a me ke kūpaʻa ʻana i ka pala o ka paipu kila.
12CrMoG a me15CrMoGʻO ka hoʻohui ʻana o ka chromium a me ka molybdenum e hoʻoikaika i ke kūpaʻa ʻana i ka oxidation a me ka ikaika wela kiʻekiʻe o ka paipu kila, a kūpono ia no nā wahi me nā mahana a me nā kaomi kiʻekiʻe.
12Cr2MoG a me 12CrMoVG: Ua hoʻomaikaʻi hou ʻia ka haku mele metala, me ka ikaika wela kiʻekiʻe a me ke kūpaʻa ʻana i ka oxidation, a hana maikaʻi loa i nā wahi koʻikoʻi loa.
Nā noi
Hoʻohana nui ʻia nā paipu kila humuhumu maʻamau GB/T5310 i nā paipu paila a me nā mea hoʻololi wela, ʻo ia hoʻi i nā lako wela kiʻekiʻe a me ke kaomi kiʻekiʻe e like me nā paila kikowaena mana, nā paila ʻoihana, a me nā paila wela ʻōpala. Hiki i kēia mau paipu kila humuhumu ke kū i nā kaomi hana a me nā mahana kiʻekiʻe loa, e hōʻoiaʻiʻo ana i ka hana pono a me ke ola lōʻihi o nā paila a me nā mea hoʻololi wela. Eia kekahi, hoʻohana ʻia kēia mau paipu kila i nā lako hoʻololi wela i ka ʻoihana petrochemical, e hoʻonui hou ana i kā lākou wahi noi.
Hōʻuluʻulu manaʻo
Ua lilo nā paipu kila humuhumu maʻamau GB/T5310 i huahana makemake ʻia no nā paipu paila mahu kiʻekiʻe a ma luna o ke kaomi ma muli o ko lākou mau waiwai mea maikaʻi loa a me nā ʻano hana like ʻole. Inā he 20G, 20Mg, 20MoG, 12CrMoG a me nā mea ʻē aʻe, a i ʻole 15MoG, 20MoG, 12CrMoG a me nā papa kila ʻano alloy ʻē aʻe, hōʻike lākou āpau i ke kūpaʻa maikaʻi loa i ka oxidation wela kiʻekiʻe a me ka ikaika wela kiʻekiʻe, e hāʻawi ana i nā hōʻoia hilinaʻi no ka hana palekana a me ka pono o nā lako ʻoihana.
