1. HOOLAHA NUI O LSAW PIPE

Longitudinally Submerged Arc Welding paipu (i ho'opau 'ia me LSAW paipu).Hoʻokumu ʻia ka Longitudinally Submerged Arc Welding (LSAW) ma ka hoʻohana ʻana i kahi pā hoʻokahi ma ke ʻano he mea maka, e kaomi ana (ka ʻōwili) i ka pā kila i loko o kahi paipu paʻa i loko o ka mold a i ʻole ka mīkini hoʻoheheʻe ʻia, a me ka hoʻohana ʻana i ʻelua ʻaoʻao submerged arc welding a hoʻonui i ka. anawaena.ʻO ka huahana i hoʻopau ʻia he ākea ākea o nā kikoʻī, a ʻo ka weld he paʻakikī maikaʻi, plasticity, uniformity a compactness, a loaʻa iā ia nā pōmaikaʻi o ka nui o ka paipu anawaena, ka paia paipu mānoanoa, ke kūpaʻa kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa corrosion.

I ke kūkulu ʻana i nā paipu aila lōʻihi a me ke kinoea maikaʻi, ʻo ka hapa nui o nā paipu kila i makemake ʻia he mau paipu i hoʻopaʻa ʻia.Wahi a ka API maʻamau, i loko o nā paipu aila nui a me ke kinoea, ʻo ke kuʻi pololei i hoʻopaʻa ʻia i ke arc welded paipu ʻo ia wale nō ke ʻano paipu i koho ʻia i ka wā e hele ai ma waena o ka papa I a me ka papa 2 mau wahi e like me nā wahi kiʻekiʻe kiʻekiʻe, nā moʻo kai, a me nā wahi nui o ke kūlanakauhale.

2. NA ANO PAPA LSAW

Ma muli o nā ʻano hana hoʻoheheʻe like ʻole, hiki ke hoʻokaʻawale ʻia i:

UOE welded paipu:ma hope o ke kuʻi mua ʻana o ka pā kila hoʻokahi, U-forming, O-forming, wili kūloko, wili waho, hoʻonui anu mechanical a me nā kaʻina hana ʻē aʻe;

JCOE wili paipu:e like me ke kaʻina hana o "JCOE" pre-weld, hana, anuanu-hoʻonui ma hope o ka welding;

HME wili paipu:Hoʻokumu ʻia ia e ka "CCO" e ka mandrel rolling method, a me ke kaʻina o ka hoʻonui ʻana i ke anuanu ma hope o ke kuʻi ʻana.

3. KA PALAPALA HANA O LSAW PIPE

ʻO nā ʻāpana ʻenehana nui o LSAW penei:

Mānoanoa pā:6.4-23.8mm (0.252-0.94in) ma X80 kila kila a me 6.4-26.4mm (0.252-1.04in) ma X70 kila kila.Hiki ke hoʻonui ʻia ka mānoanoa o ka pā i nā degere like ʻole ke hoʻohaʻahaʻa ʻia ka mea.

Kūlana huahana:ISO3183-3, API Spec 5L, GB9711, etc.

ʻO ke kaʻina pololei i hoʻopaʻa ʻia i loko o ke arc welded steel pipe anawaena a hiki i Φ406.4-Φ1422.4mm

Hiki i ka paipu kila ke piʻi i ka 12.2m ka lōʻihi a ʻo ka mānoanoa o ka pā he 6.4-26.4mm ma ka × 70 kila kila.

4.MAIN HUULU OLSAWPIPE:

1) Loaʻa i ka paipu kila he weld longitudinal, a ua hoʻopaʻa ʻia nā weld o loko a me waho e kahi wili arc submerged.

2) Ma hope o ka hoʻonui ʻia ʻana o ka mechanical, ʻo ke koʻikoʻi o loko o ka paipu kila he liʻiliʻi a puʻunaue like ʻia, hiki ke pale pono i ke koʻikoʻi o ka corrosion cracking, kiʻekiʻe kiʻekiʻe ka pololei, a maʻalahi hoʻi no ka hana wiliwili ma ka pūnaewele.

3) Ke hoʻohana nei i ke kaʻina hana o ka pre-weld after-weld, paʻa ke kaʻina hana weld a kiʻekiʻe ka maikaʻi o ka weld.

4) He mea maʻalahi nā welds e hoʻokō i ka hoʻāʻo ʻole i ka wā o ka hana ʻana a me ka hoʻāʻo ʻole ʻana i ke kahua i ka wā hoʻohana.

5) He nui ka laulā huaʻōlelo, hiki ke hana i ke anawaena liʻiliʻi, ka mānoanoa o ka pā nui a hiki ke hana pū i ke anawaena nui a me ka paipu kila mānoanoa nui.

ʻO mākou ʻo JINBAICHENGamea hana, mea hoʻopuka, mea paʻa a me ka mea hoʻolako i kahi ʻano qualitative o LSAW Pipes.Loaʻa iā mākou ka mea kūʻai mai Thane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar.
