ERWhe uila-kū'ē kū'ē welded kila paipu, Resistance welded kila paipu ua maheleia i ka hoololi o welded kila paipu a me DC welded kila paipu ma na ano elua.Hoʻokaʻawale ʻia ʻo AC e like me nā alapine like ʻole i ka welding low-frequency, IF welding, welding o ultra-IF a me ke kiʻekiʻe-frequency welding.Hoʻohana nui ʻia ka welding kiʻekiʻe no ka hana ʻana i ka paipu kila lahilahi a i ʻole ka mānoanoa o ka paia o ka paipu kila, ke kiʻekiʻe kiʻekiʻe o ka wiliwili i loko o ka hoʻopili ʻana a me ka hoʻoheheʻe induction.Hoʻohana maʻamau ka hoʻoheheʻe DC no ka paipu kila liʻiliʻi.No laila, ma keʻano o ka laulā, kiʻekiʻe-frequency welded paipu i loko o ka ERW paipu mea he kiʻekiʻe-frequency wili kaʻina hana e hana ERW paipu.ERW Longitudinal holomua huahana hana ma ke kahua o ka aila a me ke kinoea waihona a me ka lawe 'ana, alakai maikai, oi aku ka waiwai o ka paipu kila.

SAW paipu kilahe pōkole o Submerged Arc Welding Steel Pipe, ia mea he hoʻohana o submerged arc soldering kaʻina hana e hana kila, ke kaʻina hana i ka loa kiʻekiʻe o keia manawa density, ka flux papa e pale aku i ka wikiwiki lilo o ka wela, a concentrated ma ka welding aina.Submerged arc weld of high quality, high production efficiency, arc and smoke a few features of submerged arc welded pipe is much used in pressure vessels, pipe manufacturing, beams, low pressure fluid, steel works.ʻO nā huahana nui o nā paipu kila SAW LSAW Steel Pipe, Longitudinally Submerged Arc Welding Steel Pipe LSAW steel pipe, ʻo ia ka hoʻohana ʻana i ka hana hoʻoheheʻe ʻana i ka hana o ka paipu kila seam pololei.

ʻO ka ʻokoʻa ma waena o ka erw a me ka paipu kila ʻike
E like me ka ERW kila paipu a me SAW paipu kila i loko o ka paipu i ka wā e hana ana, kuʻihao a me ka hana okoa, no laila, elua ano o ka paipu kila i ka hana aia kekahi mau okoa.
(1) ʻOi aku ka maikaʻi o ka maikaʻi o ka ili paipu kila ERW ma mua o ka paipu i hoʻoheheʻe ʻia arc submerged, ʻo ka ʻili o ka paipu kila ERW maʻemaʻe, ʻoluʻolu, nani, SAW paipu kila i loko a me waho hoʻi i hoʻoikaika ʻia.

(2) ERW kila paipu weld 'ano hemahema ma mua o ka ike kila paipu.ʻIke ʻia ka paipu kila me ka solvent i waiho ʻia, ʻoi aku ka nui o nā ʻano kīnā, ma waho aʻe o nā hemahema leo, aia nā pahele uea.ERW kila paipu weld defects wale uea-laina a me ka pololei welds, i ka nana kaʻina hana oluolu e hahai, a me na defects i loko o ka kiekie noonoo ma, i ka manawa o ka nele o implicit, kani ultrasonic noonoo i ka ikaika, oluolu e ike.

(3) ERW kila paipu e pili ana i ike kila paipu i koena koʻikoʻi lākiō ua haʻahaʻa.Ma muli o ka hoʻololi ʻana o ka paipu ERW i ke kaʻina hana deformation, hui pū ʻia ka nui oval oval, elliptical vertical hoʻololi a me ka ʻāʻī, e liʻiliʻi ke koʻikoʻi o ka paipu ERW.Ua hōʻike ʻia ka hoʻāʻo kino ʻana i nā kikoʻī like, ka mea like me ka paipu ERW ma hope o ka ʻoki ʻana ma ke koʻi, ʻoi aku ka liʻiliʻi o nā ʻoki axial a me nā transverse ma mua o ka paipu i hoʻoheheʻe ʻia i loko o ka wai.

(4) ERW Pipe holoʻokoʻa hana o ka mea like, i ka wa e lilo ai ka paipu i defective, kila scrap hookolokolo, e ae kuʻihao.SAW paipu kila i aeia, a paipu kuʻihao hana a me ka holoʻokoʻa hana mea inconsistent, kuʻihao wahi prone i stress corrosion māwae.Hōʻike nā hoʻokolohua i ka hoʻāʻo ʻana i ka luhi corrosion fatigue ERW pipe spiral submerged arc welded pipe lōʻihi ma mua o ke ola.
