Hoʻohana nui ʻia ia e hana i ke kila carbon seamless kiʻekiʻe, no nā paipu boiler, nā paipu wela super

no ka ʻoihana bolier, paipu hoʻololi wela a me nā mea like ʻole me ka nui a me ka mānoanoa

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 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.

ʻO ka hoʻāʻo ʻana i ke ahi:

E like me nā koi o ka mea kūʻai aku a i ʻōlelo ʻia i loko o ka ʻaelike, hiki ke hana ʻia ka paipu kila me ka anawaena o waho ≤76mm a me ka mānoanoa o ka pā ≤8mm. Hana ʻia ka hoʻokolohua ma ka wela lumi me kahi lipi o 60 °. Ma hope o ke puhi ʻana, pono e hoʻokō ka wikiwiki o ke ahi o ka anawaena waho i nā koi o ka papa ma lalo nei, a ʻaʻole pono ka mea hoʻāʻo e hōʻike i nā māwae a i ʻole nā haehae.

Ho'āʻo paʻakikī:

E hana ʻia nā hoʻāʻo paʻakikī ʻo Brinell a i ʻole Rockwell ma nā specimens mai ʻelua paipu mai kēlā me kēia ʻāpana
