I loko o ka ʻoihana mīkini, pono ke kāpili i kahi huahana me ka nui o ka noi kiʻekiʻe, akā ma ke ʻano he mea kūʻai aku, ʻo ke kāpili i lohe pinepine ʻia i ka wā e loaʻa ai nā nīnau a ka mea kūʻai aku he nui nā huahana. I kēia lā, e hoʻolauna ka mea hoʻoponopono iā ʻoe i nā ʻano ʻē aʻe o ke kāpili.

Hoʻopuni pinepine ʻia ke kāpili e ke apo, a ʻo ka mea o ke kāpili he hao galvanized, kila kila (201/304/316). Aia kekahi poʻe kūʻai aku e kapa ana i ka ʻāʻī puʻu he kāpili. Hana ʻia ka ʻāʻī puʻu me ke kila kila, a like ke ʻano me ke kāpili. ʻO ke kekelē o ka hoʻopaʻa ʻana o ka paipu ke ʻano o ka pilina a me ka paʻa. Hoʻohana pinepine ʻia ia i ka hoʻopaʻa ʻana i nā paipu mīkini like ʻole a me nā paipu lako kemika.

Nui nā ʻano o nā ʻūmiʻi paipu, ʻo ia hoʻi nā ʻano kaumaha, nā ʻano māmā, nā ʻano noho ZR, nā ʻano O-kau, nā ʻano hui pālua, nā ʻano ʻekolu-wili, nā ʻano R, nā ʻano U, a pēlā aku. ʻO nā ʻano ʻeono mua o nā ʻūmiʻi he kūpono no nā lako kaumaha a he nui. Eia nō naʻe, he ʻano like nā ʻano o nā ʻūmiʻi paipu ʻano R a me nā ʻūmiʻi paipu ʻano U me nā ʻūmiʻi, ʻo ia hoʻi, ʻo kā lākou mau mea hoʻopaʻa nui he mau hose metala, nā paipu laholio a i ʻole hiki ke hoʻopaʻa i nā hose he nui i ka manawa hoʻokahi. Aia ma ke ʻano nui: ʻūmiʻi paipu ʻano R me ke kaula laholio, ʻūmiʻi paipu ʻano R i hoʻoluʻu ʻia i ka plastic, ʻūmiʻi paipu ʻano R i nā ʻano he nui, ʻūmiʻi holo lio ʻano U me ke kaula laholio, ʻūmiʻi paipu ʻano U i hoʻoluʻu ʻia i ka plastic, ʻūmiʻi paipu ʻano U i nā ʻano he nui, a hiki ke hoʻopilikino ʻia nā kikoʻī ma waho aʻe o ke kūlana aupuni. ʻO ka mea hana o ke kaula he EPDM, silica gel, a me ka laholio kūikawā me ka hana pale lapalapa. He paʻa a paʻa kēia ʻano mea hoʻopaʻa paipu metala, kūpaʻa maikaʻi i ka pala, pale wai, pale ʻaila, maʻalahi e wehe a hoʻohana hou ʻia. Hoʻohana nui ʻia i ka ʻenekinia kūkulu hale, nā lako mīkini, nā kaʻa ikehu hou, nā mīkini ʻoihana uila, nā locomotive uila a me nā ʻoihana ʻē aʻe.
