Wahi a nā koi hana like ʻole oGB/T9711-2017ʻO nā paipu kila pipeline, hiki ke hoʻokaʻawale ʻia ka tempering i nā ʻano penei e like me ka mahana tempering:
1. Hoʻomaʻamaʻa haʻahaʻa haʻahaʻa (150-250 kekelē)
ʻO ke ʻano i loaʻa ma o ka hoʻomaʻamaʻa haʻahaʻa haʻahaʻa, ʻo ia ka martensite i hoʻomaʻamaʻa ʻia. ʻO kona kumu, ʻo ia ka hoʻemi ʻana i ke kaumaha kūloko a me ka palupalu o ke kila i hoʻomaʻamaʻa ʻia me ka mālama ʻana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ke kila i hoʻomaʻamaʻa ʻia, i mea e pale aku ai i ka haki ʻana a i ʻole ka hōʻino mua ʻana i ka wā e hoʻohana ai. Hoʻohana nui ʻia ia no nā mea hana ʻoki kalapona kiʻekiʻe, nā mea ana, nā paipu kila pipeline GB/T9711, nā bearings ʻōwili a me nā ʻāpana carburized, a pēlā aku. ʻO ka paʻakikī ma hope o ka hoʻomaʻamaʻa ʻana, ʻo ia ka HRC58-64.
2. Hoʻomaʻamaʻa mahana waena (250-500 kekelē)
ʻO ke ʻano i loaʻa ma o ka hoʻomaʻamaʻa ʻana i ka mahana waena, ʻo ia ka troostite i hoʻomaʻamaʻa ʻia. ʻO kona kumu, ʻo ia ka loaʻa ʻana o ka ikaika hua kiʻekiʻe, ka palena elastic a me ke kūpaʻa kiʻekiʻe. No laila, hoʻohana nui ʻia ia no ka mālama ʻana i nā paipu kila pipeline GB/T9711 like ʻole a me nā ʻōmole hana wela, a ʻo ka paʻakikī ma hope o ka hoʻomaʻamaʻa ʻana he HRC35-50 maʻamau.
3. Hoʻomaʻamaʻa wela kiʻekiʻe (500-650 degere)
ʻO ke ʻano i loaʻa ma o ka hoʻomehana wela kiʻekiʻe ʻo ia ka troostite tempered. ʻO ka mālama wela e hoʻohui ana i ka quenching a me ka hoʻomehana wela kiʻekiʻe e kapa pinepine ʻia ʻo quenching a me ka tempering treatment, ʻo ke kumu o ia mea e loaʻa ai nā waiwai mechanical piha me ka ikaika maikaʻi, ka paʻakikī, ka plasticity a me ka toughness. No laila, hoʻohana nui ʻia ia i nā ʻāpana kūkulu koʻikoʻi o nā kaʻa, nā paipu kila pipeline GB/T9711, nā mea hana mīkini, a me nā mea ʻē aʻe, e like me nā koʻokoʻo hoʻohui, nā bolts, nā gears a me nā ʻauamo. ʻO ka paʻakikī ma hope o ka hoʻomehana ʻana he HB200-330.
ʻO nā papa hana nui o nā paipu pipeline (API5L/GB/T 9711-2017):

Nānā: Nui nā leka i hoʻohui ʻia ma hope oKūlana API 5Lpapa kila paipu, e hōʻike ana i kēia mau mea:
He aha ka manaʻo o ka pipeline steel grade N? ʻO "N" ke kū nei no ka normalizing heat treatment
He aha ke ʻano o ka pae kila pipeline Q? ʻO "Q" ke kū nei no ka quenching + tempering heat treatment
He aha ka manaʻo o ka papa kila pipeline NS? ʻO "NS" ke kū nei no ka normalizing a me ke kūpaʻa ʻana i ka waikawa a me ka corrosion,
He aha ka manaʻo o ka papa kila pipeline QS? ʻO "QS" ke kū nei no ka quenching + tempering heat treatment a me ke kūpaʻa waikawa a me ka corrosion
