Hōʻike Hydraustatic:

Pono e ho'āʻoʻia ka paipu kila me ka hydraulic hoʻokahi. ʻO 20 MPa ka piʻi kiʻekiʻe loa. Ma lalo o ke kaomi ho'āʻo, ʻaʻole i emi iho ka manawa hoʻokūpaʻa ma mua o 10 S, a ʻaʻole pono e kahe ka paipu kila.

Ma hope o ka ʻae ʻana o ka mea hoʻohana, hiki ke hoʻololi ʻia ka Hydraulic Test e ka Eddy Current Testing or Magnetic Flux Leakage Testing.

ʻO nā paipu e koi ana i ka nānā hou aʻe e pono ke nānā ʻia me ka Ultrasonically. Ma hope o ke kūkākūkā ʻana e koi ʻia ka ʻae o ka ʻaoʻao a i ʻōlelo ʻia i loko o ka ʻaelike, hiki ke hoʻohui ʻia nā hoʻāʻo hōʻino ʻole.

Ho'āʻo palahalaha:

ʻO nā paipu me ka anawaena waho i ʻoi aku ma mua o 22 mm e hoʻāʻo ʻia i ka hoʻāʻo ʻana. ʻAʻole ʻike ʻia ka Delamination, nā kiko keʻokeʻo, a i ʻole nā mea haumia i ka wā o ka hoʻokolohua holoʻokoʻa.
