He aha ka Pipe Seamless ʻO Hot Rolled?

Pono nā paipu i nā ʻoihana e like me ka aila a me ke kinoea, ke kūkulu ʻana, ka automotive, a me ka hana mīkini. Ma waena o nā ʻano like ʻole,paipu wela ʻole ʻiakū i waho no kona ikaika, kūlike, a me ka hiki ke kū i ke kaomi kiʻekiʻe a me ka mahana. ʻAʻole like me nā paipu i hoʻopaʻa ʻia, ʻaʻohe o nā paipu seamless, ʻo ia ka mea e kūpono ai no nā noi koʻikoʻi. Ma kēia ʻatikala, e ʻimi mākou i ke ʻano o ka paipu wela, pehea i hana ʻia ai, kona mau pono, a me kāna mau noi maʻamau ma waena o nā ʻoihana.

1. Wehewehe: He aha ka Hot Rolled Seamless Pipe?

A paipu wela ʻole ʻiahe ʻano paipu kila i hana ʻiame ka wili olea hoʻokumu ʻia ma o akaʻina ʻōwili wela. ʻO ka huaʻōlelo "seamless" e hōʻike ana ʻaʻole i hui pū ʻia ka paipu ma kona lōʻihi, e hoʻonui ai i kona ikaika a me kona kūpaʻa.

ʻO ka ʻōwili wela e pili ana i ka hana ʻana i ka paipu manā wela kiʻekiʻe, maʻamau ma luna o 1000 ° C, e ʻae i ke kila e maʻalahi a hana ʻia. Hoʻopuka kēia ʻano i kahi paipu ikaika, homogeneous kūpono no kahi ākea o nā noi koi.

2. Pehea i hana ʻia ai ka paipu wela ʻole ʻia?

ʻO ka hana ʻana i ka paipu wela ʻōwili ʻole ʻia e pili ana i nā ʻanuʻu nui:

a) Hoʻomākaukau Billet

• Ua ʻoki ʻia kahi billet kila cylindrical paʻa i ka lōʻihi i makemake ʻia.

• Hoʻomaʻamaʻa ʻia ka billet i loko o ka umu ahi i kahi wela kiʻekiʻe e hiki ai ke malleable.

b) ʻOkuʻi

• Hoʻokomo ʻia ka billet i hoʻomehana ʻia i loko o ka hale wili e hana ai i kahi kikowaena hollow.

• Hoʻohana ʻia kahi piercer wili a me nā wili e hana i ke ʻano tubular maʻamau.

c) Elongation

• Hoʻokomo ʻia ka billet i hou ʻia (ʻo ia hoʻi he paipu hollow) ma waena o nā wili elongation e like me nā wili mandrel a i ʻole nā wili plug.

• ʻO kēia mau wili e hohola i ka paipu a hoʻomaʻemaʻe i ka mānoanoa o ka paia a me ke anawaena.

d) Ke Kaʻa Wela

• Hoʻonui ʻia ke ʻano a me ka nui o ka paipu ma o nā wili wela.

• Mālama kēia i ka kūlike a me ka pololei o ke ana.

e) Hoʻoluʻu a hoʻopololei

• Hoʻomaʻalili ʻia ka paipu ma kahi conveyor a i ʻole i ka ea.

• A laila hoʻopololei ʻia a ʻokiʻoki i nā lōʻihi i makemake ʻia.

f) Nānā a ho'āʻo

• Hoʻomaʻamaʻa nā paipu i nā hoʻokolohua like ʻole a luku ʻole (e laʻa, ultrasonic, hydrostatic).

• Hana ʻia ka hōʻailona ʻana a me ka hoʻopili ʻana e like me nā kūlana ʻoihana.

sakysteelhāʻawi i nā paipu hili ʻole wela i nā ʻano like ʻole a me nā nui, hoʻāʻo piha ʻia a hōʻoia ʻia no ka hōʻoia ʻana i ka maikaʻi.

3. Nā mea nui o Hot Rolled Seamless Pipe

• Hoʻokumu ʻole: ʻAʻohe seam welded, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana a me ke kūpaʻa o ke kūkulu ʻana.

• Kūleʻa wela kiʻekiʻe: Hiki ke pale i ka wela kiʻekiʻe me ka ʻole o ka deformation a i ʻole ka hemahema.

• Ka hoomanawanui: Hana maikaʻi ma lalo o ke kiʻekiʻe o loko a i waho paha.

• Mānoanoa Pā like: ʻO ka ʻōwili wela e ʻoi aku ka maikaʻi o ka mana mānoanoa.

• Hoʻopau ʻili maikaʻi: 'Oiai 'a'ole ma'ema'e e like me nā paipu huki anu, ua 'ae 'ia nā paipu wela no ka ho'ohana 'oihana.

4. Nā mea a me nā kūlana

Loaʻa nā paipu wela i ʻōwili ʻia ma nā ʻano mea like ʻole ma muli o ke noi:

Mea maʻamau:

• Ke kila kalapona (ASTM A106, ASTM A53)

• Ke kila kila (ASTM A335)

• Ke kila kila (ASTM A312)

• Ke kila wela haʻahaʻa (ASTM A333)

Nā kūlana maʻamau:

• ASTM

• EN/DIN

• API 5L / API 5CT

• JIS

• GB/T

sakysteelhāʻawi i ka hoʻokō piha me nā kikoʻī o ka honua e hoʻokō i nā pono o nā mākeke honua.

5. Nā noi o Hot Rolled Seamless Pipe

Hoʻohana ʻia nā paipu wili wela ma nā ʻāpana he nui ma muli o ko lākou hilinaʻi a me ka hana.

a) ʻOihana Aila a me Gas

• Ka lawe ʻana i ka ʻaila ʻaila a me ke kinoea maoli

• ʻO nā paipu iho a me ka pahu pahu

• Nā paipu hoʻoheheʻe

b) Hana Mana

• ʻO nā paipu paila

• Nā paipu hoʻololi wela

• ʻO nā ʻāpana superheater

c) ʻEnekinia Mechanical

• Nā ʻāpana mīkini a me nā ʻāpana

• ʻO nā kinikini hydraulic

• ʻO nā huila a me nā huila

d) Ke kūkulu ʻana a me ke kūkulu ʻana

• Nā kākoʻo hoʻolālā a me nā papa hana

• Paipu ahu

• ʻO nā alahaka a me nā hale kila

e) ʻOihana Kaʻa

• Axles a me nā ʻāpana hoʻomaha

• Nā lāʻau hoʻoili

• Nā mea hoʻokele

sakysteelhoʻolako i nā paipu wili wela i hoʻopili ʻia no kēia mau noi, e hōʻoia ana i ka lōʻihi a me nā kikoʻī kikoʻī.

6. Pono o Hot Rolled Seamless Pipe

ʻOi aku ka ikaika a me ka palekana

• ʻAʻohe hui welded ʻoi aku ka liʻiliʻi o nā wahi nāwaliwali a ʻoi aku ka maikaʻi.

Maikaʻi no ka hoʻohana ʻana i ke kiʻekiʻe

• Kūpono no ka lawe ʻana i ka wai a me ke kinoea ma lalo o ke kaomi kiʻekiʻe.

Laulā Nui

• Loaʻa i nā anawaena nui a me nā mānoanoa pā paʻakikī e hoʻokō me nā paipu welded.

ʻOi aku ka lōʻihi o ke ola lawelawe

• ʻOi aku ka maikaʻi o ka pale ʻana i ka luhi, ka pohā, a me ka ʻino.

ʻAnoʻano

• He kūpono no nā hana hoʻolālā a me nā hana mechanical.
