Koi hoao

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.

Ho'āʻo Nondestructive:

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.

Ho'āʻo paʻakikī:

No ka paipu o nā Papa P91, P92, P122, a me P911, Brinell, Vickers, a i ʻole Rockwell e hana ʻia nā hoʻāʻo paʻakikī ma kahi hōʻailona mai kēlā me kēia ʻāpana.

Hoʻāʻo Bend:

No ka paipu nona ke anawaena i oi aku i ka NPS 25 a o kona anawaena me ka manoanoa o ka paia he 7.0 a emi mai paha e hoao ia i ka hoao piko ma kahi o ka hoao palahalaha. Hiki ke hā'awi 'ia ka paipu 'ē a'e i like a 'oi aku paha ma mua o NPS 10 i ka ho'ā'o pi'o ma kahi o ka ho'ā'o palahalaha ma muli o ka 'ae o ka mea kū'ai.
