ʻO ka hoʻolauna ʻana i ke kila kila kila kiʻekiʻe a me ke kila hoʻoheheʻe ʻia i nā paipu kila maʻemaʻe ʻole no ka piʻi kiʻekiʻe a ma luna o nā paipu paila mahu.

GB/T5310ʻO nā paipu kila liʻiliʻi maʻamau he mau huahana kiʻekiʻe i hoʻolālā ʻia no nā paipu paila kīʻaha kiʻekiʻe a ma luna aʻe. Hana ʻia lākou me ke kila kila kila kiʻekiʻe a me nā mea kila kila kila e hōʻoia ai i kā lākou hana maikaʻi loa a me ka hilinaʻi ʻana i nā kaiapuni kiʻekiʻe a me ke kiʻekiʻe. Hoʻohana nui ʻia kēia paipu kila maʻemaʻe i ka hana ʻana i nā pipeline boiler a me nā mea hoʻololi wela, e hāʻawi ana i kahi hōʻoia paʻa no ka hana ʻoihana.

Papa nui

GB/T5310ʻO nā paipu kila maʻamau maʻamau i hana nui ʻia me ka Cr-Mo alloy a me Mn alloy, a ʻo nā māka nui e komo pū.20G, 20Mg, 20MoG, 12CrMoG, a me nā mea ʻē aʻe. ʻO kēia mau mea i loaʻa ka ikaika kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka oxidation, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i nā wahi hana koʻikoʻi me ka ʻole o ka hemahema. Ma waena o lākou:

20G: He kila hoʻolālā kalapona kūlana kiʻekiʻe me ka plasticity maikaʻi a me ka paʻakikī, hoʻohana mau ʻia i nā paipu paila paila haʻahaʻa.
20Mg: ʻO ka hoʻohui ʻana i ka manganese i ka 20G e hoʻomaikaʻi hou i ka ikaika a me ka paʻakikī o ka mea, kūpono no nā paipu paila kīwaha a me ke kiʻekiʻe.
20MoG: Hoʻohui ʻia ka Molybdenum i ka 20G, kahi e hoʻomaikaʻi nui ai i ka pale ʻana i ka wela a me ke kū ʻana o nā kolo, a kūpono ia no nā paipu paila kiʻekiʻe.
12CrMoG: Alloy structural steel i loaʻa i ka chromium a me ka molybdenum, me ka maikaʻi loa kiʻekiʻe-mehana oxidation kū'ē a me ka kiʻekiʻe-mehana ikaika, kūpono no ka ultra-kiʻekiʻe-pressure boiler paipu.
Alloy structural steel grades

ʻO nā pae kila kila o GB/T5310 maʻamau maʻamau ʻo nā paipu kila ʻaʻohe 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, etc. ʻO kēia mau māka o nā paipu kila he mau ʻano mechanical like ʻole a me nā pae kūpono e like me nā kaʻina hana kemika like ʻole. :

15MoG a me 20MoG: ʻO ka hoʻohui ʻana i kahi nui kūpono o ka molybdenum e hoʻomaikaʻi nui i ka ikaika wela kiʻekiʻe a me ke kūpaʻa ʻana o ka paipu kila.
12CrMoG a15CrMoG: ʻO ka hoʻohuiʻana o ka chromium a me ka molybdenum e hoʻonui i ke kū'ē o ka oxidation a me ka ikaika kiʻekiʻe o ka paipu kila, a ua kūpono i nā wahi me nā mahana kiʻekiʻe a me nā pilikia.
12Cr2MoG a me 12CrMoVG: Hoʻonui hou ʻia ka haku mele ʻana, me ka ikaika wela kiʻekiʻe a me ka pale ʻana i ka oxidation, a hana maikaʻi loa i nā kaiapuni koʻikoʻi.
Nā noi
Hoʻohana nui ʻia nā paipu kila maʻamau ʻo GB / T5310 i nā paipu boiler a me nā mea hoʻololi wela, ʻoi aku ka nui o ke kiʻekiʻe kiʻekiʻe a me nā mea paʻi kiʻekiʻe e like me nā mea hoʻoheheʻe mana, nā ʻoihana ʻoihana, a me nā ʻōpala wela. Hiki i kēia mau paipu kila maʻemaʻe ke kū i nā puʻe hana kiʻekiʻe loa a me nā mahana, e hōʻoia ana i ka hana kūpono a me ke ola lōʻihi o nā paila a me nā mea hoʻololi wela. Eia kekahi, hoʻohana pū ʻia kēia mau paipu kila i nā mea hoʻololi wela i ka ʻoihana petrochemical, e hoʻonui hou i kā lākou mau wahi noi.
Hōʻuluʻulu manaʻo
ʻO GB/T5310 nā paipu kila maʻamau maʻamau i lilo i huahana makemake no ke kiʻekiʻe kiʻekiʻe a ma luna o nā paipu paila mahu ma muli o kā lākou waiwai waiwai maikaʻi loa a me ka laulā o nā noi.
