ʻI ka aila a me ke kinoea pipeline kaʻina hana anti-corrosion,LSAW paipu kila ʻO ka lāʻau anti-corrosion surface e hoʻoholo ai i ke ola o kekahi o nā kumu nui, ʻo ia ka LSAW steel pipe anti-corrosion layer a inā paha ka hui ʻana o kahi kumu paʻa.ʻO ke aʻo ʻana o nā hui ʻoihana, ma ka hoʻohui ʻana i ke ola o ka uhi ʻana ma muli o ke ʻano o ka uhi ʻana, Coating quality a me ke kūkulu ʻana i nā kumu kūlohelohe, LSAW steel pipe coating surface treatment of life-span of about 50%, no laila, pono e paʻa i loko. e like me ka uhi maʻamau i ka ʻili o nā koi paipu kila LSAW, ka hoʻomaikaʻi mau ʻana i ke ʻano o ka hoʻomaʻamaʻa ʻana i ke kila kila kila, ʻo ka paipu kila LSAW ka mea nui o nā ʻano aʻe i ka hoʻohui ʻana i nā ʻāpana embroidery:

1, ka hoʻohana ʻana i ka hoʻomaʻemaʻe solvent, emulsion e hoʻomaʻemaʻe i ka ʻili kila, i mea e hoʻokō ai i ka lawe ʻia ʻana o ka aila, ka momona, ka lepo, nā lubricants a me nā mea like ʻole, akā ʻaʻole hiki ke hoʻoneʻe i ka lepo kila, oxide, welding flux, etc., no laila, ʻo nā hana kūʻē i ke aupuni he mea hoʻohui wale nō.

2, pickling

ʻO ka maʻamau, ʻelua mau ala i hoʻohana ʻia e hana i ke kaʻina hana kemika a me ka electrolytic pickling, pipeline corrosion me ka hoʻohana ʻana i ka etching kemikal wale nō, e wehe i ka oxidation, ka ʻōpala, nā uhi kahiko, i kekahi manawa hoʻohana ʻia e like me ke one-blasting ma hope o ka hana hou ʻana.ʻOiai hiki i ka hoʻomaʻemaʻe kemika ke hoʻokō i kahi maʻemaʻe maʻemaʻe a me ka roughness, akā ʻo ka anchorpattern māmā, a maʻalahi hoʻi e hoʻohaumia i ke kaiapuni a puni.

3, nā mea hana rust

Hoʻohana maʻamau i kahi pulupulu uea a me nā mea hana ʻē aʻe ma ka ʻili kila i hoʻomaʻemaʻe ʻia, hiki ke hoʻoneʻe i ka oxide, ʻōpala, welding slag.Hiki i ka ʻōpala lima ke piʻi aku i nā mea hana mana papa Sa2 i ka pae Sa3, inā pili ʻia i kahi pālākiō paʻa ʻili kila, ʻaʻole ʻoluʻolu nā mea hana ʻōpala, E hōʻea i nā koi kūkulu o ka hohonu corrosion o ke kumu heleuma.

4, e hoʻopuʻu i ka ʻōpala i ka lepo e ka mana kiʻekiʻe ka māmā holo kiʻekiʻe e hoʻohuli ʻia i ka ʻōpala i hoʻoiho ʻia, no laila ka pana kila, grit, nā ʻāpana uea, nā minelala a me nā ikaika centrifugal ikaika ʻē aʻe i loko o ke kaʻa. , ʻAʻole hiki iā ʻoe ke hoʻopau loa i nā oxides, rust a me ka lepo a me ka paipu kila LSAW i ka hopena abrasive koʻikoʻi a me ke kuleana o ka friction, akā no ka hoʻokō ʻana i ka roughness like ʻole.ʻAʻole hiki ke hoʻonui wale i ka hana o ke kino adsorption tube surface, a hiki ke hoʻonui i ka papa corrosion a me ka mechanical adhesion o ka tube surface.No laila, ʻo ka jet rust ke ala maikaʻi loa e hoʻoheheʻe ai i ka paipu.ʻO ka mea maʻamau, hoʻohana nui ʻia ka pana peening rust i loko o ka paipu no ka hoʻomaʻamaʻa ʻana i ka ʻili, pana i ka puhi ʻana i nā paipu kila seam pololei i hoʻohana nui ʻia no ka mālama ʻana i waho. paipu kila humuhumu i ka lua o ka eha, ma ka hoʻohui i ka pololei seam kila paipu ma o ka humuhumu, embroidered huahana hiʻona a me ka mea e oi aku ka laumania ma mua, ma mua o pololei humuhumu kila paipu i hoʻohana 'ia i loko o ka oihana kila.
