Pip kila ʻolee he kaula kila lōʻihi me ka ʻāpana keʻa ʻaʻohe a puni. Ma muli o ke ʻano ʻokoʻa o kāna kaʻina hana, he ikaika kiʻekiʻe a me ke kūpaʻa paʻi maikaʻi. ʻO nā paipu kila ʻole i hoʻokomo ʻia i kēia manawa he ʻelua mau mea a me nā kikoʻī: 15CrMoG grade, kikoʻī 325 × 14 a12Cr1MoVGpapa, kiko'ī 325×10.

Nā hiʻohiʻona a me ka hoʻohana ʻana o15CrMoGpaipu kila
ʻO 15CrMoG he kila kila chromium-molybdenum, nā mea kemika nui o ka carbon (C), chromium (Cr), molybdenum (Mo), a me nā mea'ē aʻe. Eia kekahi, loaʻa iā 15CrMoG ka hana kuʻi maikaʻi a me ka processability.

Hoʻohana
Hoʻohana nui ʻia nā paipu kila ʻole i hana ʻia o 15CrMoG no ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe o nā pipelines a me nā lako, a hoʻohana nui ʻia i nā kula aʻe:

ʻOihana mana: nā mea hoʻomehana wela, nā mea hoʻomaʻamaʻa hou, nā poʻo a me nā paipu mahu nui i nā mea kanu wela.
ʻOihana Kemika: ʻōnaehana paipu no nā mea hoʻoheheʻe wela kiʻekiʻe i nā mea hana kemika.
ʻOihana ʻaila: nā paipu wela kiʻekiʻe a me nā mea hoʻololi wela i nā hale hoʻoheheʻe.
Hiki i kēia paipu kila ke mālama i nā waiwai mechanical maikaʻi loa i nā wela kiʻekiʻe, a kūpono loa i nā mahana hana lōʻihi ma waena o 500 ° C a me 580 ° C.
Nā hiʻohiʻona a me ka hoʻohana ʻana i nā paipu kila 12Cr1MoVG
ʻO 12Cr1MoVG he kila kila chromium-molybdenum-vanadium kiʻekiʻe i hōʻike ʻia e ka ikaika kiʻekiʻe, ke kūpaʻa creep maikaʻi, a me ke kūpaʻa ikaika a me ka pale ʻana. Hoʻohālikelike ʻia me 15CrMoG, hoʻohui ia i kahi liʻiliʻi o ka vanadium (V), kahi e hoʻomaikaʻi hou ai i kona kūpaʻa kiʻekiʻe a me ke kūpaʻa.
Hoʻohana
Hoʻohana pinepine ʻia nā paipu kila maʻemaʻe i hana ʻia me 12Cr1MoVG i nā kaiapuni kiʻekiʻe a me ke kaomi kiʻekiʻe.
Ke kahua ikehu: nā mea hoʻomehana wela kiʻekiʻe, nā mea hoʻomaʻamaʻa hou a me nā paipu i nā mea kanu wela a me nā mea kanu nuklea.
ʻOihana Petrochemical: kiʻekiʻe-mehana a me ke kiʻekiʻe kiʻekiʻe kemika lako a me nā pipeline.
ʻO ka hana ʻana o ka paila: ka hana ʻana i nā paipu paila kiʻekiʻe no nā hāmeʻa me nā ʻoi aku ka nui o ka hana.
He kūpono kēia ʻano paipu kila no ka hoʻohana lōʻihi ʻana i nā mahana hana ma mua o 570 ° C a he ikaika loa ka pale ʻana a me ka ductility.
ʻO ka paipu kila 15CrMoG me kahi kikoʻī o 325 × 14 a me ka paipu kila 12Cr1MoVG me kahi kikoʻī o 325 × 10 i kā lākou mau manaʻo ponoʻī. ʻO nā paipu kila hoʻoneʻe kiʻekiʻe ʻelua a hoʻohana nui ʻia i nā ʻoihana kiʻekiʻe a me nā ʻoihana kiʻekiʻe e like me ka ikehu, petrochemical, a me nā kemika. Ma muli o ke kaiapuni hoʻohana, hiki i nā mea hoʻohana ke koho i kahi mea paipu kila kūpono e hoʻokō i nā pono hana.
