Paipu kila i hoʻopaʻa ʻia ʻo ERW: paipu kila i hoʻopaʻa ʻia me ke alapine kiʻekiʻe, i hana ʻia me ka papa kila i ʻōwili wela ʻia, ma o ke kūkulu mau ʻana, ke kūlou ʻana, ka hoʻopaʻa ʻana, ka mālama wela ʻana, ka nui ʻana, ka hoʻopololei ʻana, ka ʻoki ʻana a me nā kaʻina hana ʻē aʻe.
Nā Hiʻohiʻona: Ke hoʻohālikelike ʻia me ka paipu kila wiliwili i hoʻopaʻa ʻia i loko o ke arc, loaʻa iā ia nā pono o ke kiʻekiʻe o ka pololei o ka dimensional, ka mānoanoa like o ka paia, ka maikaʻi o ka ʻili a me ke kū'ē ʻana i ke kaomi kiʻekiʻe. Akā ʻo ka hemahema, hiki ke hoʻohana wale ʻia no ka hana ʻana i nā paipu paia lahilahi liʻiliʻi. Hoʻohana nui ʻia i ke kinoea kūlanakauhale, ka lawe ʻana i ka ʻaila maka a me nā ʻoihana ʻē aʻe.
Paipu kila i hoʻopaʻa ʻia i loko o ke arc wili: paipu kila i hoʻopaʻa ʻia i loko o ke arc wili. I ke kaʻina hana ʻōwili, ua hoʻokumu ʻia kahi kihi hoʻokumu i ke kuhikuhi ʻōwili, a laila hana ʻia kahi kaʻina hana kuʻi ma hope o ke kaʻina hana ʻōwili. Loaʻa i ka huahana hope loa kahi kuʻi wili.
Nā Hiʻohiʻona: ʻO nā pono, hiki ke hana ʻia nā paipu kila me nā kikoʻī like a me nā diameters like ʻole, ʻoi aku ka laulā o ka laulā o nā mea maka, a hiki i ka weld ke pale aku i ke kaumaha nui a loaʻa i kahi kūlana kaumaha maikaʻi; ʻO nā hemahema, ʻo ka nui geometric maikaʻi ʻole, ka lōʻihi o ka weld ma mua o ka paipu kila seam pololei, a me nā hemahema welding e like me nā māwae, nā lua ea a me ka hoʻokomo ʻana o ka slag i kēlā me kēia manawa. Aia ke kaumaha welding i ke kūlana o ke kaumaha tensile. Wahi a ke Code for Design of General Long-distance Oil and Gas Pipelines, hiki ke hoʻohana ʻia ka welding arc spiral submerged ma nā wahi Class 3 a me Class 4 wale nō.
ʻO ka paipu kila i hoʻopaʻa ʻia i loko o ka wai hohonu: ka paipu kila i hoʻopaʻa ʻia i loko o ka wai hohonu, ke kaʻina hana: e ʻōwili mua i ka papa kila i loko o kahi paipu me kahi ʻōmole a i ʻole ka mīkini hana, a laila e hoʻopaʻa ʻia i loko o ka wai pālua.
Nā Hiʻohiʻona: Loaʻa i ka huahana nā pono o ka laulā ākea, ka paʻakikī kiʻekiʻe, ka plasticity maikaʻi, ka like maikaʻi a me ka compactness maikaʻi. I ke kūkulu ʻana i nā paipu aila a me ke kinoea mamao loa, pono nā paipu wili arc submerged longitudinal. Wahi a ke kūlana API 5L, ʻo ia wale nō ke ʻano paipu kila i koho ʻia ma nā wahi anuanu, nā moana a me nā wahi kūlanakauhale i noho nui ʻia.
Nā pono o ka paipu kila humuhumu
Paia mānoanoa a me ka mānoanoa.
ʻAʻohe wili. Manaʻo nui ʻia he ʻoi aku ka maikaʻi o kona waiwai a me ke kūpaʻa ʻana i ka pala.
ʻOi aku ka maikaʻi o ka ellipticity a i ʻole ka poepoe o nā paipu Seamless.
Pehea e koho ai i nā paipu kila welded a seamless paha?
ʻOiai he nui nā pono o ka paipu wili ʻia, ʻoi aku ka maikaʻi o ka paipu wili ʻole ma mua o ka paipu wili ʻia, ʻoi aku hoʻi i nā wahi ʻino, no ka mea, ʻoi aku ka ikaika, ke kaomi kiʻekiʻe a me ke kūpaʻa ʻana i ka pala.
Ma muli o ke ʻano a me ke kumukūʻai, e hoʻoholo i ke ʻano i ʻoi aku ka maikaʻi.
Wahi a nā koi o ka noi, hiki ke hana ʻia nā paipu seamless a me nā paipu welded.
Nā noi like ʻole o ka paipu humuhumu a me ka paipu welded
Paipu kila i ulana ʻia: hoʻohana nui ʻia ka paipu wili ʻia i ka ʻenekinia lako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana uila, hoʻoinu wai mahiʻai a me ke kūkulu ʻana i ke kūlanakauhale. Ka halihali wai: lako wai a me ka hoʻokahe wai. Hoʻohana ʻia no ka halihali kinoea kūlohelohe: kinoea kūlohelohe, mahu, kinoea petroleum liquefied. ʻAno: paipu paila, alahaka, uapo, alanui, kūkulu ʻana i nā paipu kūkulu, a pēlā aku.
Paipu kila humuhumu ʻole: He ʻāpana keʻa hakahaka ko ka paipu kila humuhumu ʻole a hoʻohana nui ʻia no ka lawe ʻana i nā wai, e like me ka ʻaila, ke kinoea kūlohelohe, ke kinoea kūlohelohe a me ka wai, a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka māmā o ke kaumaha o ka paipu kila ma lalo o ka ikaika kūlou a me ka torsion like, no laila he kila ʻāpana hoʻokele waiwai ia.
Inā ʻoe e noʻonoʻo ana e kūʻai i ka SEAMLESS PIPE, ERW PIPE, SSAW PIPE A I ʻOLE LSAW PIPE, e nānā i nā koho a JINDALAI nou a e noʻonoʻo e hoʻokaʻaʻike aku i kā mākou hui no ka ʻike hou aku. E hāʻawi mākou iā ʻoe i ka hopena maikaʻi loa no kāu papahana.
