Ho'āʻo palahalaha
ʻO nā paipu kila me ke anawaena o waho ʻoi aku ka nui ma mua o 22 mm a hiki i 400 mm, a ʻo ka mānoanoa o ka pā ma mua o 10 mm pono e hana i ka hoʻāʻo palahalaha. Ma hope o ka palahalaha ʻana o nā laʻana
Hoʻāʻo kulou
ʻO nā paipu kila me ke anawaena o waho ʻaʻole i ʻoi aku ma mua o 22 mm pono e hoʻokō i ka hoʻāʻo ʻana. He 90o ka huina piko. ʻO ka radius kulou he 6 mau manawa ke anawaena o waho o ka paipu kila. Ma hope o ke kulou ʻana i ka hāpana, ʻaʻole ʻae ʻia nā māwae a i ʻole nā māwae e ʻike ʻia ma ka hāpana.
ʻO ka hoʻokolokolo macroscopic
No nā paipu kila i hana pololei ʻia e ka hoʻolei mau ʻana a i ʻole nā ʻāpana kila, pono ka mea hoʻolako e hōʻoiaʻiʻo ʻaʻohe wahi keʻokeʻo, nā haumia, nā ea ma lalo o ka ʻili, nā ʻili iwi poʻo a i ʻole ke kau ʻana ma luna o ka ʻiʻo macroscopic pickled acid cross-sectional o ka billet a i ʻole. paipu kila.
Nānā hoʻopōʻino ʻole
E like me ka noi o ka aoao koi, a laila kūkākūkā ma waena o ka hoolako ana a me ka koi 'aoʻao a hōʻike 'ia i loko o ka aelike, kani ultrasonic flaw detection hiki ke hana pakahi no ka kila paipu.
