He aha ka Paipu Pāhāhā ʻAila?

He paipu kila ʻole i humuhumu ʻia ka paipu pāhāhā ʻaila i hoʻolālā ʻia no ka ʻoihana kemika ʻaila. Hoʻohana nui ʻia ia no ka wāwahi ʻana i nā mea maka ʻaila (e like me ka ʻaila maka a i ʻole ka ʻaila kaumaha) i loko o nā huahana hydrocarbon māmā, e like me ka ʻaila, ka ʻaila dīsela, a me ke kinoea wai, ma lalo o nā kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe. Hoʻohana nui ʻia ia i nā ʻāpana pāhāhā o nā hale hana hoʻomaʻemaʻe, nā lako pāhāhā catalytic, a me nā kaʻina hana kemika ʻē aʻe me nā wela kiʻekiʻe a me nā kaomi kiʻekiʻe.

Nā hiʻohiʻona o ka Paipu Pāhāhā ʻAila:

1. Mea：Hoʻohana maʻamau ʻia ke kila kalapona kiʻekiʻe, ke kila ala, a i ʻole ke kila kila (e like me 20#, 15CrMo, 12Cr1MoV, 1Cr5Mo, a pēlā aku) e hōʻoia i ka pale wela kiʻekiʻe, ka pale kaomi kiʻekiʻe, a me ka pale ʻana i ka ʻino.
2. Kaʻina hana hana：ʻO ka hapa nui he paipu kila ʻole i humuhumu ʻia, i hana ʻia e ka wili wela a i ʻole ke kaha anuanu e hōʻoia i ka mānoanoa o ka paia o ka paipu a me ka ikaika kiʻekiʻe.
3. Nā koi hana：
   • Pale wela kiʻekiʻe：ʻO ke kaʻina hana pāhāhā maʻamau ma luna o 500°C, a hiki i 700°C, e koi ana i nā mea paipu e loaʻa ka pale ʻana i ka oxidation wela kiʻekiʻe.
   • Pale kaomi kiʻekiʻe：Pono ka hopena pāhāhā i kahi kaiapuni kaomi kiʻekiʻe, a pono i nā mea paipu ke kū i ke kaomi kūloko kiʻekiʻe.
   • Pale ʻana i ka ʻino：Loaʻa paha i nā mea maka ʻaila nā mea ʻino e like me nā sulfides, a pono i nā mea paipu ke loaʻa kekahi pale ʻana i ka ʻino.
4. Nā kikoʻī：ʻO ke anawaena waho maʻamau mai 10mm a 426mm, a ʻo ka mānoanoa o ka paia mai 2mm a 50mm. Hoʻopilikino ʻia nā kikoʻī kikoʻī e like me nā pono lako.

Nā hoʻohana nui:

• Umu Pāhāhā ʻAila：Hoʻohana ʻia no ka hoʻomehana ʻana a me ka wāwahi ʻana i nā mea maka ʻaila.
• Nā mea hoʻololi wela a me nā paipu lawe：Hoʻohana ʻia no ka lawe ʻana i ka ʻaila a me ke kinoea wela kiʻekiʻe a me ke kaomi kiʻekiʻe i nā ʻāpana pāhāhā.
• Nā ʻāpana petrochemical：Hoʻohana ʻia no nā kaʻina hana e like me ka pāhāhā catalytic a me ka pāhāhā hydrogenation.

Nā kūlana pili:

ʻO ka hana ʻana a me ka hoʻohana ʻana i nā paipu pāhāhā ʻaila e hahai maʻamau i nā kūlana honua a i ʻole nā kūlana aupuni, e like me:

• Kūlana Kina：GB/T 9948 "Nā Paipu Kila ʻOle i Humuhumu ʻia no ka Pāhāhā ʻAila"
• Kūlana ʻAmelika：ASTM A335, API 5L, a pēlā aku
