ASTM A210 paipu kila He paipu kila maʻemaʻe kalapona i hoʻohana ʻia e like me ka paila a me ka superheater tubes no ke kiʻekiʻe kiʻekiʻe a me ka puʻuwai kiʻekiʻe, e like me nā kikowaena mana a me nā paila ʻoihana.
Nā pihi hoʻokele
Nui o ka ASTM A210
Anawaena waho: 1/2i(12.7mm)≤ OD ≤5in (127mm)
Mānoanoa Pā: 0.035 in (0.9mm)≤ WT ≤0.500 in (12.7mm)
Hiki ke hoʻolako ʻia nā paipu me nā ʻāpana ʻē aʻe, inā e hoʻokō kēlā mau paipu i nā koi ʻē aʻe a pau o kēia kikoʻī.
Mea Maka
Hoʻomaʻamaʻa hana hao--E pepehi ʻia ke kila.
ʻO ke kila make e pili ana i ka hoʻohui ʻana o kekahi mau deoxidizers e like me ke silika, aluminika, a me ka manganese i ka wā o ka hoʻoheheʻe ʻana o ke kila.
Hiki i kēia mau mea hoʻohui ke hana me ka oxygen i loko o ke kila e hana i nā oxide paʻa, pēlā e hoʻemi ai i ka ʻike oxygen i loko o ke kila a pale i ka hoʻokumu ʻana o nā inclusions oxidizing.
Papa ASTM A210

ASTM A210 Seamless Steel Tube Production Process
E hana ʻia nā paipu kila ma ke kaʻina hana ʻole a e hana ʻiahoʻopau wela or pau anue like me ka mea i hoakakaia.
ʻO ka maʻamau, ʻo nā paipu kila me ke anawaena ʻoi aku ka nui ma mua o 30 millimeters ua hoʻopau wela a ʻo nā mea me ke anawaena liʻiliʻi a i ʻole like me 30 millimeters ua pau i ke anu.ʻAʻole paʻa kēia ʻano o ka hoʻokaʻawale akā hiki ke hoʻohana ʻia ma ke ʻano he ala wikiwiki a maʻalahi e hoʻoholo ai i ke ʻano hana o ka paipu kila seamless.
Hoʻomaʻamaʻa Wela
ʻAʻole pono ka mālama wela no nā paipu wela.
E hā'awi 'ia nā paipu anu i ho'opa'a 'ia ma hope o ke ka'ina ho'opau anu.

Na Waiwai Mechanical
ʻAʻole pili nā koi waiwai mīkini i nā paipu liʻiliʻi ma mua1/ 8i [3.2 mm] i loko o ke anawaena a i ʻole 0.015 in. [0.4 mm] i ka mānoanoa.

Hāʻawi ka papa 4 i nā helu elongation liʻiliʻi i helu ʻia no kēlā me kēia1/32i. [0.8 mm] emi i ka mānoanoa pā.
Ma kahi o ka mānoanoa o ka pā ma waena o nā waiwai ʻelua i hōʻike ʻia ma luna, e hoʻoholo ʻia ka liʻiliʻi elongation waiwai e ka hoohalike penei:
Nā ʻāpana Imperial(i loko o): E = 48t+15.00

ma hea:
E = elongation i 2 in. a i ʻole 50 mm, %,
t = mānoanoa maoli o ka specimen.
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.

ʻAʻole pili kēia mau lapaʻau i ka maikaʻi o ka ʻili o ka paipu akā hiki ke hoʻopili i kāna mau waiwai noi hope.
Hoʻokumu i nā hana
Ke hoʻokomo ʻia i loko o ka paila, e kū mau nā paipu me ka hoʻonui ʻana a me ka wili ʻole me ka ʻike ʻole ʻia o nā māwae a me nā hemahema.Ke hoʻohana pono ʻia, e kū nā paipu superheater a pau i ka forging, welding, a me ke kulou ʻana i nā hana e pono ai no ka noi ʻana me ka ʻole o nā hemahema.

Hoʻohana ʻia i ka hana ʻana i nā boilers liʻiliʻi a liʻiliʻi o ka puʻuwai haʻahaʻa, e like me nā boilers kū i luna, nā boilers noho i lalo, a me nā boilers ʻē aʻe i hoʻohana ʻia no ka hoʻomehana ʻoihana a hale paha.
ʻO nā superheater nā ʻāpana o ka paila i hoʻohana ʻia e hoʻokiʻekiʻe i ka mahana o ka mahu ma luna o kona wahi paila, a ua kūpono nā paipu ASTM A210 no ka hana ʻana i kēia mau ʻāpana wela kiʻekiʻe.
ʻO kā mākou huahana pili
ʻO mākou kahi mea hana kiʻekiʻe kiʻekiʻe welded carbon steel paipu a me ka mea hoʻolako mai Kina, a me kahi mea hoʻoheheʻe paipu kila maʻemaʻe, hāʻawi iā ʻoe i kahi ākea o nā paipu kila!
