ʻO nā hiʻohiʻona o nā paipu no ka haki ʻana i ka ʻaila, ka mea momona, a me ka ʻoihana kemika

ʻO nā paipu kila no ka ʻaila, petrochemical, a me nā ʻoihana kemika (me ka ʻoihana kemika lanahu), i kapa pinepine ʻia he paipu kila no ka ʻoihana kemika, e pili ana i nā paipu kila i hoʻohana ʻia i ka ʻoihana petrochemical, me ka hoʻomaʻemaʻe ʻaila, ka hana fiber kemika, ʻoihana kemika lanahu, kemika. ʻoihana, a me ka hana ʻana i nā mea momona. Wahi a ke ʻano hana o nā paipu kila, ua hoʻokaʻawale ʻia lākou i nā paipu kila ʻole a me nā paipu welded. E like me ke ʻano o ke kila, hiki ke hoʻokaʻawale ʻia i nā paipu kila kalapona, nā paipu kila kila, nā paipu kila kila, a me nā paipu kila composite i hoʻohana nui ʻia i nā makahiki i hala. Ma muli o ka hana nui o ke kino a me ke kemika i loko o ke kaʻina hana kemika ʻekolu i hana ʻia ma lalo o nā kaomi kikoʻī a me nā mahana. Loaʻa i nā mea maka, nā kaʻina hana, a me nā huahana nā mea a pau i ka wela a me nā koi koi, a ʻo nā mea maka, nā kaʻina hana, a me nā huahana āpau i kekahi degere o ka corrosiveness. No laila, aia kekahi mau koi ʻenehana no nā paipu kila i hoʻohana ʻia i ka hana kemika kikoʻī.

ʻO ka hiʻohiʻona o nā kumu waiwai ikehu o Kina he waiwai i ka aila a me ka liʻiliʻi o ka lanahu. ʻO ka hoʻohana ʻana i nā kumuwaiwai lanahu nui o Kina a me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe ʻana i ka lanahu e hoʻohuli i ka lanahu i wahie wai kiʻekiʻe he ala maikaʻi ia no Kina e hoʻohana ai i ka lanahu wela, ʻoi aku ka lanahu sulfur kiʻekiʻe.

ʻO ka hoʻoheheʻe ʻana o ka lanahu pololei he kaʻina hydrogenation ma lalo o ke kaomi kiʻekiʻe a me ke kiʻekiʻe o ka wela, no laila pono nā mea hana a me nā mea hana e loaʻa i ke kūpaʻa kiʻekiʻe a me ke kūpaʻa hydrogen corrosion ma lalo o nā kūlana hydrogen koʻikoʻi. Eia kekahi, ʻo nā mea i hoʻoheheʻe pololei ʻia i loko o nā ʻāpana paʻa e like me ka lanahu a me nā catalysts, no laila pono e hoʻoponopono i nā pilikia ʻenehana e like me ka sedimentation, ka lole, a me ka hoʻopaʻa ʻana i hoʻokumu ʻia e nā ʻāpana i hana ʻia. ʻO ka hoʻohana ʻana i nā paipu kila liʻiliʻi nui no ka lawe ʻana e hiki ke kāohi i ka hoʻokaʻawale ʻana o ka slurry a me ke koena o ka paipu lawe i ka wā o ke kaʻina hana. ʻO ka mānoanoa o ka pā o nā paipu kila ʻole hiki ke piʻi i ka 105mm
