ʻO ka paipu welded arc submerged ʻelua ʻaoʻao pololeiPaipu JCOEUa hoʻokaʻawale ʻia ka paipu kila humuhumu pololei i ʻelua ʻano ma muli o ke kaʻina hana hana: ka paipu kila humuhumu pololei alapine kiʻekiʻe a me ka paipu kila humuhumu pololei i hoʻopaʻa ʻia i lalo o ke arc. Ua hoʻokaʻawale ʻia nā paipu kila humuhumu pololei i hoʻopaʻa ʻia i lalo o ke arc e like me UOE, RBE, JCOE,Nā paipu kila LSAW, a pēlā aku ma muli o kā lākou ʻano hana. He maʻalahi ke kaʻina hana paipu JCOE, me ka pono hana kiʻekiʻe, nā kumukūʻai haʻahaʻa, a me ka hoʻomohala wikiwiki.
ʻO ka paipu JCOE kekahi o nā ʻano hana paipu kila humuhumu pololei, a me kekahi o nā lako. Ma Kina, hoʻohana nui ʻia ʻo GB/T3091-2008 a me GB/T9711.1-2008, ʻoiai ʻo API-5L ke kūlana honua. Hana nui ʻia ka paipu JCOE me ka hoʻohana ʻana i ka wili ʻākuhi i hoʻopaʻa ʻia i lalo i ka wai ʻelua ʻaoʻao. No ka hoʻokō ʻana i nā koi o nā kūlana pili, hele nā huahana ma o nā kaʻina hana he nui e like me ke kulou ʻana, ka hui ʻana, ka wili ʻana i loko, ka wili ʻana i waho, ka hoʻopololei ʻana, a me nā wēlau pālahalaha.
ʻO nā papahana paipu nui, nā papahana hoʻoili wai a me ke kinoea, ke kūkulu ʻana i nā pūnaewele paipu kūlanakauhale, nā hale kila, nā piliki alahaka, ke kūkulu ʻana i ke kūlanakauhale, a me ke kūkulu ʻana i ke kūlanakauhale e hoʻohana āpau i ka paipu JCOE.
ʻO ke ʻano kaumaha: [(ke anawaena waho-mānoanoa o ka paia)*mānoanoa o ka paia]*0.02466=kg/m (kaumaha no ka mika).
Hoʻohana pinepine ʻia ʻo Q235A, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, a me nā mea ʻē aʻe.
ʻAʻole ʻae ʻia nā pelu, nā māwae, ka delamination, ka lap welding, ka haki ʻana o ke arc, ka burn-through, a i ʻole nā hemahema kūloko ʻē aʻe nona ka hohonu e ʻoi aku ma mua o ka ʻokoʻa haʻahaʻa o ka mānoanoa o ka paia ma nā ʻili o loko a me waho o nā paipu kila JCOE straight seam. ʻAe ʻia nā hemahema kūloko ʻē aʻe me ka hohonu ʻaʻole i ʻoi aku ma mua o ka ʻokoʻa haʻahaʻa o ka mānoanoa o ka paia.
wili paipu yuantaihe 1 laina hana paipu JCOE.
ʻO Yuantai tube millhiki ke hana i nā paipu kila LSAW, OD: 355.6-1420mm, mānoanoa: 21.3-50mm, lōʻihi: 1-24M.wili ʻāpana hakahaka ʻo Yuantaihiki nō hoʻi ke hana i ka ʻāpana hakahaka huinahā OD: 10 * 10-1000 * 1000mm ʻāpana hakahaka huinahā OD: 10 * 15-800 * 1100mm, mānoanoa: 0.5-60mm, lōʻihi: 0.5-24M. I kēia makahiki, ua loaʻa i ka hui ʻo yuantai derun ka palapala hōʻoia DNV,paipu kila yuantai no ke kūkulu mokuE hoʻolako ʻia ma kahi nui,nā paipu kila yuantai no ke kūkulu mokuua hoʻololi ʻia mai nā paipu kila JCOE
