Nānā nui
Me kā mākou ʻike waiwai a me nā lawelawe noʻonoʻo, ua ʻike ʻia mākou he mea kūʻai hilinaʻi no nā mea kūʻai honua he nui no ka A210 Carbon Steel Seamless Boiler Tube / Boiler Pipe, Aloha mākou i nā mea kūʻai aku ma nā wahi āpau i ka ʻōlelo e launa pū me mākou no nā hui ʻoihana ʻoihana e hiki mai ana. ʻO kā mākou mea kūʻai ka mea maikaʻi loa. Ke koho ʻia, Pono no ka wā pau ʻole! E hoʻolako mākou i nā mea ʻoi aku ka maikaʻi me nā hoʻolālā like ʻole a me nā lawelawe ʻoihana. Hoʻokipa maikaʻi mākou i nā hoaaloha mai ke ao holoʻokoʻa e kipa i kā mākou hui a hui pū me mākou ma ke kumu o nā pōmaikaʻi lōʻihi a me kekahi.
Palapala noi
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
