Nūhou - ASTM A106 Seamless Carbon Steel Pipe: Alakaʻi piha no nā noi wela kiʻekiʻe

Nā paipu kila kalapona ASTM A106hoʻohana nui ʻia i nā noi ʻoihana wela kiʻekiʻe a me ke kaomi kiʻekiʻe. Hoʻolālā ʻia e hoʻokō i nā kūlana ASTM International, hāʻawi kēia mau paipu i ka hana mīkini maikaʻi loa, hilinaʻi kiʻekiʻe, a me ka hoʻohana like ʻana i ka ikehu, petrochemical, a me nā ʻoihana. Hāʻawi kēia alakaʻi i kahi ʻike piha oNā paipu ASTM A106, me nā māka, nā ana, nā waiwai mechanical, a me nā noi maʻamau.

He aha ka ASTM A106 Seamless Pipe?

Ho'ākākaʻo ASTM A106nā paipu kila kalapona humuhumu ʻoleno ka lawelawe wela kiʻekiʻe. ʻAʻole e like me nā paipu i hoʻopili ʻia, hana ʻia kēia mau mea mai nā billet paʻa ma onā kaʻina hana ʻoki wela, ʻōwili, a me ka hoʻopau ʻana, e hōʻoiaʻiʻo ana i kahi ʻano like me ka ʻole o nā humuhumu wili.

Nā pono koʻikoʻi oNā paipu humuhumu ASTM A106:

ʻAno like me ke ʻano ʻole o nā humuhumu weld
Ke kū'ē wela kiʻekiʻe
Ka ikaika tensile a me ka ikaika hua maikaʻi loa
Kūpono no ke kulou ʻana, flanging, a me ka kuʻihao

Hana kēia mau ʻanoNā paipu ASTM A106kūpono nonā hale hana mana, nā hale hana petrochemical, nā hale hoʻomaʻemaʻe, nā paila, a me nā ʻōnaehana paipu kiʻekiʻe.

Nā Papa ASTM A106

Loaʻa nā paipu ASTM A106 i ʻekolu mau papa:Papa A, Papa B, a me Papa CLoaʻa i kēlā me kēia papa nā waiwai kemika a me nā ʻano mechanical kūikawā no nā kūlana lawelawe like ʻole.

Papa	Kalapona Kiʻekiʻe (C)	Manganese (Mn)	Ikaika Hua (MPa)	Ikaika Hoʻopaʻa (MPa)	Hoʻohana Maʻamau
A	0.25%	0.27–0.93%	≥ 205	≥ 330	Paipu haʻahaʻa-kaomi, haʻahaʻa-mahana
B	0.30%	0.29–1.06%	≥ 240	≥ 415	ʻO ka lawelawe wela kiʻekiʻe maʻamau
C	0.35%	0.29–1.06%	≥ 275	≥ 485	Nā wahi wela kiʻekiʻe, kaomi kiʻekiʻe, koi nui

Nā Ana a me nā Nui

Loaʻa nā paipu ASTM A106 i nā ʻano nui like ʻole o nā paipu maʻamau (NPS) mai 1/8” a i 48”, me ka mānoanoa o ka paia e pili ana i nā papa kuhikuhi ASME B36.10M, e like me SCH40 (STD), SCH80 (XH), SCH160.

Hiki ke hoʻopau wela ʻia a huki anu ʻia paha nā anawaena liʻiliʻi (< 1½”)

ʻO nā anawaena nui aʻe (≥ 2”) ua hoʻopau pinepine ʻia me ka wela

ʻO ka lōʻihi he 6-12 mika a i ʻole i hoʻopilikino ʻia e like me nā koi o ka papahana

Nā Waiwai Mekanika

Ua hoʻolālā ʻia nā paipu ASTM A106 no nā noi wela kiʻekiʻe, e hāʻawi ana i:

Ka ikaika tensile kiʻekiʻe a me ka hua

Paʻa wela maikaʻi loa

ʻO ka ductility maikaʻi a me ka weldability

Hoʻāʻo hopena koho no nā kūlana koʻikoʻi

Papa	Ikaika Hua (MPa)	Ikaika Hoʻopaʻa (MPa)	Hoʻolōʻihi (%)
A	≥ 205	≥ 330	≥ 30
B	≥ 240	≥ 415	≥ 30
C	≥ 275	≥ 485	≥ 25

Nā Hoʻohana Maʻamau

Nā paipu humuhumu ASTM A106hoʻohana nui ʻia ma nā ʻoihana like ʻole, e komo pū ana me:

Nā Hale Hana Mana: Nā paipu mahu, nā paila, nā mea hoʻololi wela

Petrochemical & Refinery: Nā paipu kemika wela kiʻekiʻe, kaomi kiʻekiʻe

ʻAila a me ke Kinoea: Nā paipu halihali kinoea kūlohelohe a me ka ʻaila

ʻOihana: Nā hale hana kemika, ke kūkulu moku, nā moku kaomi, nā paipu ʻoihana

ʻO ko lākou hiki ke kū i ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, a me nā wahi ʻino e hoʻolilo iā lākou i koho makemake ʻia i nā papahana ʻenekinia ma ka honua holoʻokoʻa.

No ke aha e koho ai i nā paipu humuhumu ASTM A106?

Kūkulu maʻalahihōʻoia i ka palekana a me ka hilinaʻi i nā ʻōnaehana kaomi kiʻekiʻe

Nā māka he nui(A/B/C) e ʻae i ka ikaika i hana kūikawā ʻia a me ka hana mahana

Ka laulā ākeauhi i nā anawaena liʻiliʻi a nui loa

Ka ʻike ʻana i ke kūlana honuahōʻoia i ka kūlike me nā code ʻenekinia honua

Nā Manaʻo Koʻikoʻi

Koho PapaʻO ka Papa B ka mea maʻamau, ʻoiai ʻo ka Papa C no nā noi kaomi kiʻekiʻe/wela kiʻekiʻe.

Papa Kuhikuhi Paipu: Koho e like me ke kaomi, ka mahana, a me nā koi o ke kahe.

Nā Koina Hana: E hōʻoia i ke kūpono no ke kulou ʻana, ka hoʻoheheʻe ʻana, a i ʻole nā hana ʻē aʻe.

Hoʻokō KūlanaE hōʻoia i ka palapala hōʻoia ASTM a i ʻole ASME SA106 no nā ʻōnaehana koʻikoʻi o ke kaomi.

Hopena

Nā paipu kila kalapona ASTM A106he hopena hilinaʻi, versatile, a me ka hana kiʻekiʻe no nā noi wela kiʻekiʻe a me ke kaomi kiʻekiʻe. ʻO ke koho ʻana i ka papa kūpono, ka nui, a me ka mānoanoa o ka paia e hōʻoiaʻiʻo ana i ka palekana kūpono, ka pono, a me ke ola lawelawe lōʻihi i nā hale hana mana, nā hale hoʻomaʻemaʻe, nā hale hana petrochemical, a me nā ʻōnaehana paipu ʻoihana.
