ASTM A192 (ASME SA192) ʻO ka paipu kila he paipu kila kalapona maʻemaʻe i hoʻohanaʻia i nā kaiapuni kiʻekiʻe a me ke kaomi kiʻekiʻe a hoʻohana nuiʻia i nā paila a me nā mea hoʻololi wela.
Anawaena waho: 1/2 ″ – 7 ″ (12.7 mm – 177.8 mm);
Mānoanoa pā: 0.085 ″ – 1.000 ″ (2.2 mm – 25.4 mm);
Hiki ke hoʻolako ʻia nā ʻano nui ʻē aʻe o ka paipu kila e like me ka mea e pono ai, inā e hoʻokō ʻia nā koi ʻē aʻe a pau o A192.
Hana ʻia ʻo ASTM A192 me ka hoʻohana ʻana i kahi kaʻina hana ʻole a ua hoʻopau wela a i ʻole anu-hoʻopau e like me ka mea e pono ai;
Eia kekahi, pono e noʻonoʻo ka ʻike o ka paipu kila i ka wela a i ʻole ke anuanu.
Hoʻopau wela: Hōʻike i ke kaʻina hana o ka hoʻopau ʻana i nā ana hope loa o ka paipu kila i kahi kūlana wela.Ma hope o ka hana ʻana o ka paipu kila i kahi kaʻina hana wela e like me ka ʻōwili wela a i ʻole ke kiʻi wela, ʻaʻole ia e hana anu.ʻOi aku ka ʻoi aku o ka paʻakikī a me ka ductility o nā paipu kila i hoʻopau ʻia me ka wela, akā loaʻa nā ʻano hoʻomanawanui nui.
Ua pau ke anu: Hoʻopili ʻia ka paipu kila a hiki i kona mau ʻāpana hope e nā kaʻina hana anu e like me ka ʻōwili anu a i ʻole ke kaha kiʻi anu ma ka lumi wela.ʻO nā paipu kila i hoʻopau ʻia i ke anuanu, ʻoi aku ka pololei o ka hoʻomanawanui ʻana a me nā ʻili maʻalahi akā hiki ke kaumaha i kekahi paʻakikī.
ʻAʻole pono nā paipu kila maʻemaʻe wela i ka mālama wela.
Hoʻomaʻamaʻa ʻia nā paipu kila maʻemaʻe i hoʻopaʻa ʻia i ka wela ma 1200°F [650°C] a ʻoi aku paha ma hope o ka mālama ʻana i ke anu.

Inā ʻaʻole i kuhikuhi ʻia ma ka ASTM A192, nā mea i hoʻolako ʻia ma lalo o kēia kikoʻī e kūlike me nā koi pili oASTM A450/A450M.
ʻO Rockwell Hardness: 77HRBW.
No nā paipu kila me ka mānoanoa pā ma lalo o 0.2" [5.1 mm].
ʻO Brinell Hardness: 137HBW.
No ka manoanoa o ka paia paipu kila o 0.2" [5.1 mm] a oi.
No nā koi pono hana, e nānā i ka ASTM A450, 'ikamu 23.
· Ka pinepine: Hoʻokomo ʻia kēlā me kēia paipu kila i kahi hoʻokolohua hydrostatic pressure.
· Manawa: E mālama i ke kaomi liʻiliʻi no 5 kekona.
· Waiwai kaomi wai: Ua helu ʻia me ka hoʻohana ʻana i kēia ʻano.E nānā i ka ʻāpana.
ʻīniha - Nā ʻāpana paona: P = 32000 t/D
Nā Mokuna SI: P = 220.6t/D
P = kaomi ho'āʻo hydrostatic, psi a i ʻole MPa;
t = mānoanoa o ka pā i ʻōlelo ʻia, in. a i ʻole mm;
D = i kuhikuhi ʻia ke anawaena waho, i loko a i ʻole mm.
· Ka hopena: Inā ʻaʻohe leakage o nā paipu, manaʻo ʻia ua hala ka hoʻāʻo.
Hiki ke hoʻololi i ka hoʻāʻo hydrostatic me ka hoʻāʻo non-destructive kūpono.
Eia naʻe, ʻaʻole i kuhikuhi ka maʻamau i ke ʻano hoʻāʻo non-destructive e hiki ke hoʻohana ʻia.
ʻO nā paipu i ka wā e hoʻokomo ʻia ai i loko o ka paila e kū i ka hoʻonui ʻana a me ka wili ʻole me ka ʻike ʻole ʻia o nā māwae a me nā hemahema.ʻO nā paipu superheater i ka wā e hoʻoponopono pono ʻia e kū i nā hana forging, wili, a me nā hana kulou e pono ai no ka noi me ka ʻole o ka hoʻomohala ʻana i nā hemahema.
Ke kila Botophe mea hana kiʻekiʻe kiʻekiʻe welded carbon kila paipu a me ka mea hoʻolako mai Kina, a me ka seamless steel pipe stockist, e hāʻawi iā ʻoe i ka laulā o nā paipu kila!
Kāhea iā mā˚ouno ka ʻōlelo ʻana mai kahi hale kūʻai paipu kila maʻemaʻe Kina.
