(1) Ho'āʻo Hydraulic
Pono e ho'āʻoʻia ka paipu kila i ka hydraulically.
(2) Ho'āʻo palahalaha
ʻO nā paipu kila me ke anawaena o waho ma mua o 22mm a 400mm a me ka mānoanoa o ka paia ʻaʻole i ʻoi aku ma mua o 10mm e hoʻokō ʻia i kahi hoʻāʻo palahalaha.
(3) Ho'āʻo ʻāʻā
ʻO ka paipu kila me ka mānoanoa o ka paia ʻaʻole i ʻoi aku ma mua o 8 mm hiki ke hoʻokō ʻia i kahi hoʻāʻo flare me kahi taper luna o 30 °, 45 ° a i ʻole 60 °.
(4) Ho'āʻo kūlou
ʻO nā paipu kila me ke anawaena o waho ʻaʻole iʻoi aku ma mua o 22 mm e hoʻokau ʻia i ka hoʻāʻo ʻana.
(5) Ka ho'āʻo hoʻomakeʻole
E like me nā koi o ka mea kūʻai aku, e hoʻāʻo ʻia ka paipu kila i ka ultrasonically.
ʻAʻohe māwae o ka paipu kila i loko a me waho o ka ʻili, ka ʻili, ka ʻāʻī a i ʻole ka hoʻokaʻawale ʻana, a pono e hoʻopau loa ʻia kēia mau hemahema.ʻAʻole ʻoi aku ka hohonu o ka hoʻomaʻemaʻe ma mua o ka ʻae ʻole ʻana o ka mānoanoa o ka pā i koho ʻia, a ʻo ka mānoanoa maoli o ka pā ma ke kahua hoʻomaʻemaʻe ʻaʻole e emi iho ma mua o ka palena iki i ʻae ʻia e ka pā.
ʻO ka hōʻailona, ka hōʻailona a me nā kikoʻī maikaʻi o nā paipu kila e hoʻokō me nā ʻōlelo o GB/T 2102.
