He paipu kila welded anei ka paipu kila kalapona?

ʻAʻole welded paipu kila carbon. ʻO ka paipu kila kalapona e pili ana i ka mea kiko'ī o ka paipu kila he kila kalapona, e pili ana i ka hao-carbon alloy me ka carbon content Wc ma lalo o 2.11%. Ma waho aʻe o ke kalapona, loaʻa iā ia kahi liʻiliʻi o ka silika, manganese, phosphorus, sulfur a me nā mea haumia ʻē aʻe. a me nā mea ʻē aʻe i koe. Eia kekahi, he nui nā noi o kēia paipu kalapona kalapona, i hoʻohana nui ʻia i ke kūkulu ʻana, nā alahaka, nā alahao, nā kaʻa, nā moku a me nā ʻoihana hana mīkini like ʻole.

Hiki ke hoʻokaʻawale ʻia nā paipu kalapona i nā paipu kalapona i hoʻopaʻa ʻia a me nā paipu kalapona ʻole e like me ke kaʻina hana.

Hiki ke hoʻokaʻawale ʻia nā paipu kalapona kila i ʻekolu mau ʻano: nā paipu kila i hoʻopaʻa ʻia i loko o ke arc, nā paipu kila wiliwili, a me nā paipu kila wili pololei kiʻekiʻe e like me ke ʻano hana o ka weld seam.
Longitudinal welded pipe: Aia ka weld i ka laina pololei, no laila ua kapa ʻia ʻo ia ka paipu wili wili pololei.
ʻO ka paipu wiliwili wiliwili: ʻO ke kuʻi weld i loko o ke ʻano spiral, i kapa ʻia ʻo spiral welding.

Loaʻa i nā ʻano hana wili ʻekolu ko lākou pono a me nā hemahema, a ʻo ka mea e hoʻohana ai e pili ana i nā koi hoʻolālā. Hiki ke hoʻohana ʻia ka paipu kila welded carbon steel i nā kula he nui, e like me ka lako wai a me nā papahana hoʻoheheʻe, nā papahana piling, nā pipeline wai, ka aila a me ka hoʻoili kinoea, nā pou kūkulu a me nā papahana ʻē aʻe. ʻO ke ʻano kuʻikuʻi o kēia manawa o ka paipu kila i hoʻopaʻa ʻia ma ka ʻaoʻao ʻelua. He kiʻekiʻe ka maikaʻi o kēia ala kuʻi, kiʻekiʻe weld maikaʻi a me ka ʻili maʻalahi.

ʻO ke ʻano hana hoʻohua ʻana o ke kila kila kila:

Hoʻokaʻawale ʻia nā paipu kila kila i ʻelua mau ʻano: ʻo nā paipu kila wela (extruded) a me nā paipu kila ʻole i huki ʻia (rolled) ma muli o kā lākou hana hana ʻokoʻa. Hoʻokaʻawale ʻia nā paipu anu i huki ʻia (rolled) i ʻelua ʻano: nā paipu poepoe a me nā paipu ʻano kūikawā.

1. Hot-rolled (extruded) carbon steel seamless steel paipu: poepoe paipu billet → wela → hou aku → ekolu-roll kea olokaa, hoomau olokaa a extrusion → paipu wehe → sizing (a ho'ēmi) → hooluolu → pololei → wai Pressure ho'āʻo ( a i ʻole ka ʻike hapa) → māka → waiho ʻia

ʻO ka mea maka no ka ʻōwili ʻana i ka paipu kalapona maʻemaʻe ʻole he poepoe tube billet, a e ʻoki ʻia ka embryo poepoe e ka mīkini ʻokiʻoki e ulu i nā bila me ka lōʻihi o 1 mika, a lawe ʻia i ka umu e ka conveyor kāʻei. Hāʻawi ʻia ʻo Billet i loko o ka umu e wela ai, ʻo ka mahana ma kahi o 1200 degere Celsius. He hydrogen a acetylene ka wahie. ʻO ka hoʻomalu ʻana i ka mahana i loko o ka umu ahi kahi mea nui. Ma hope o ka puka ʻana o ka paipu poepoe i waho o ka umu ahi, pono e hou ʻia ma o ka ʻoi kaomi. ʻO ka mea maʻamau, ʻo ka piercer maʻamau ʻo ia ka piercer cone roll. ʻO kēia ʻano piercer he kiʻekiʻe ka hana hana, maikaʻi ka huahana maikaʻi, hoʻonui nui perforation anawaena, a hiki ke komo i nā ʻano kila like ʻole. Ma hope o ka ʻō ʻana, ʻolokaʻi ʻia ka billet paipu poepoe, ʻōwili mau ʻia a hoʻokuʻu ʻia paha e nā ʻōwili ʻekolu. Ma hope o ka extrusion, pono e wehe ʻia ka paipu no ka nui. ʻO ka hoʻopaʻa ʻana i nā lua i loko o ka billet e hana i kahi paipu. Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o ke anawaena o waho o ka drill bit o ka mīkini sizing. Ma hope o ka nui o ka paipu kila, komo ia i loko o ka hale hoʻomaha a hoʻomaʻalili ʻia e ka wai. Ma hope o ka maʻalili ʻana o ka paipu kila, e hoʻopololei ʻia. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ka paipu kila i ka mea ʻike kīnā metala (a i ʻole hydraulic test) e ke kāʻei conveyor no ka ʻike hewa o loko. Inā loaʻa nā māwae, nā ʻōpū a me nā pilikia ʻē aʻe i loko o ka paipu kila, e ʻike ʻia lākou. Ma hope o ka nānā ʻana i ka maikaʻi o nā paipu kila, pono ke koho lima paʻa. Ma hope o ka nānā ʻana i ka maikaʻi o ka paipu kila, e pena i ka helu serial, kikoʻī, helu pūʻulu hana, etc. me ka pena. A huki ʻia i loko o ka hale kūʻai e ka crane.

2. Huki anu ('ōwili) carbon steel seamless steel paipu: poepoe paipu blank → wela → perforation → poʻomanaʻo → annealing → pickling → ʻaila ʻaila ( keleawe plating) → multi-pass anu kiʻi (cold rolling) → blank tube → wela wela → Straightening → hoʻāʻo hydrostatic (ʻike hewa) → hōʻailona → hale kūʻai
