ʻO ke ʻano ʻino o ka ʻili paipu kila LSAW

LSAW paipu kilaua hoʻokumu ʻia e ka ʻili o ka ʻili o ka paʻa lahilahi a me ka ikaika o ke kiʻi ʻoniʻoni chromium-waiwai maikaʻi (protection film), e pale i ka hoʻomau infiltration o nā ʻātoma oxygen, i ka oxidation, a me ke komo ʻana i ka hiki ke anti-corrosion.Inā loaʻa kekahi kumu, ʻo kēia kiʻiʻoniʻoni ka luku mau ʻana, e hoʻomau ka ea a wai oxygen a i ʻole nā ​​​​mea metala e komo i ka ʻātoma hao mai ka hoʻopaʻa ʻana mau o ka hoʻokumu ʻana o ka hao oxide wehe, e mau ana ka corrosion.ʻO kēia kiʻiʻoniʻoni ma ke ʻano o ka nui o ka pōʻino, ʻoi aku ka maʻamau o ke ola o kēlā me kēia lā i hōʻuluʻulu ʻia penei:

1 LSAW kila paipu ili waiho huahana me nā metala ʻē aʻe i loko o nā ʻāpana lepo a i ʻole nā ​​mea metala heterogeneous i loko o ka ea humid, a me nā mea kila kila ma waena o ka condensate, ʻelua i hui pū ʻia i kahi micro-battery, e hoʻoulu ai i nā hopena kemika uila, ua pōʻino ke kiʻi pale, kapa ʻia ʻo ia ka pōʻino electrochemical.

2 Pololei paipu ili adhesion organic wai (e like me nā mea kanu, sopa, sputum, etc.), oxygen i loko o ka wai hihia, constitutes organic acids, organic acids lōʻihi ka corrosion o metala surfaces.

3 LSAW paipu kila adhesion i luna me ka waika, alkali, paʻakai (e like me ka paia hoʻonani lye, lime splash), e hoʻoulu ai i ka ʻino.

4 i loko o ka ea haumia (i loaʻa ka nui o ka sulfide, carbon dioxide, nitrogen oxide ea), ka hihia o ka wai condensed e hana i ka sulfuric acid, nitric acid, acetic acid solution point, e hoʻopōʻino kemika.

ʻO ka laulā noi o LSAW

ʻLSAW kila paipu anawaena i loko o ka laulā ma waena o 406 ~ 1600mm, ma exceptional hihia oi aku, ka lākiō o ka paia mānoanoa a me ka anawaena o ma kahi o 0.06 i 0.08.Hiki i ka ʻenehana haole hou ke hana i ka paipu a hiki i ka 100mm ka mānoanoa o ka paipu.

ʻO ka hana ʻoihana o ka pā kila a i ʻole ka paipu kila LSAW he mau ala wale nō, ʻo ka ʻokoʻa kumu ke ʻano o ka hana ʻana i ka paipu kila, ka paipu kila ma hope o ka hoʻokumu ʻana i ke kaʻina hana e like me ka like.ʻO nā loina Methodological o ka hana ʻana i ka weld e pili ana i ka māhele ʻana o ke kila, e like me ka māhele ʻana o nā paipu e weld i ʻelua mau ʻano kumu: hili pololei a me spiral seam steel pipe.E pili ana i kēia, ka hana ʻana o ka paipu wili wili pololei i ka hana ʻana a me ka hana ʻana i ka paipu seam spiral.ʻO ke ʻano hoʻohana nui ʻia ʻo ia ka wili arc submerged (SAW), kona ʻano maikaʻi, kiʻekiʻe ka huahana, ʻo ka ʻenehana a paʻa.I kēia manawa, hoʻohana nui ʻia ka paipu kila hili pololei ma nā ʻāina ʻē ma muli o ke ʻano: ea ʻāina a me ka halihali kai, ka wai a me ka ʻaila pahu paipu;lawe kemika a me nā huahana kemika o ka paipu kila kuhiliʻole;hale ʻoihana moana me ka paipu;ka hana ʻana o ka paila a me ka paipu kumu kūikawā.
