ʻO kā mākou hui kūikawā i ka hoʻokuʻu ʻana i ka paipu kila maʻemaʻepaipu galvanized, Paipu Galvanized Seamless, ʻO ka paipu galvanized SMLS, WELDED galvanized paipu.

He aha ka ʻokoʻa ma waena o ke galvaninzed wela a me ke galvanized anu?

ʻO ka galvanizing wela a me ke anu i hoʻokaʻawale i ka ʻokoʻa:

1. Galvanizing, no hoi i ike i ka wela dip galvanized, oia ka ingot hehee ai ma kiʻekiʻe wela, he helu o nā mea hoʻohui ma kahi, a laila, hoʻokomo galvanized metala kūkulu slot, ka mea metala ma luna o ka papa o ka zinc. ʻOi aku ka maikaʻi o ka corrosion hot-dip galvanizing o kona hiki, adhesion a me ka paʻakikī o ka zinc coating.
ʻO ka "cold plated" a i ʻole "plating", ʻo ia hoʻi ka paʻakai zinc ma ka electrolysis, i ka hoʻopaʻa ʻana i ka uhi, maʻamau ʻaʻohe wela, ka liʻiliʻi o ka zinc, maʻalahi loa ka hāʻule ʻana o ka ʻāina pulu.

2. Hoʻoluu wela (galvanizing)
ʻO ka galvanizing wela kahi hana kemika, ʻo ia ka hopena electrochemical.
ʻO ka galvanizing anuanu ka helu kino, palaki wale i ka papa honua o ka zinc, maʻalahi ka hāʻule ʻana o ka papa zinc. Ke kūkulu ʻana i ka hoʻohana ʻana i ka galvanizing wela.

Ke kaʻina hana galvanizing hoʻomau wela: ke kila → hoʻomehana → hoʻoluʻu i ka mahana galvanized galvanized → hoʻomaha →
Cold galvanized zinc mea wale 10-50g/m2, kona pono corrosion kū'ē ma mua o wela dip galvanized nui okoa. Galvanized e ke kumu kūʻai haʻahaʻa.
ʻO ke kino kila wela wela ka ili wela ma lalo o ke kūlana o kona pili ikaika, ʻaʻole maʻalahi e hāʻule, ʻoiai aia ka wela wela.paipu galvanizedcorrosion hanana, akā i loko o ka manawa lōʻihi loa e hoʻokō i ka ʻenehana, nā koi olakino.

3. Nā ʻokoʻa ʻenehana
ʻO ka mea mua, ʻo ka ʻokoʻa ma waena o ke kaʻina hana: ʻo ka galvanizing wela ka mea hana degreasing, pickling, dipping, hoʻomaloʻo wai immersion i loko o ka zinc hoʻoheheʻe ʻia i kekahi manawa, hiki ke hoʻāla ʻia.
ʻIke ʻia hoʻi ʻo electro-galvanized cold galvanizing, ʻo ia ka hoʻohana ʻana i nā mea hana electrolysis ma o ka degreasing, pickling ingredients post i loko o ka zinc paʻakai solution, a hoʻohui i nā mea hana electrolysis anode; ma kahi ma nā ʻāpana o ka pā zinc i hoʻopili ʻia i nā lako electrolysis maikaʻi, mana i ka, hoʻohana ʻana i ke au mai ka cathode a i ka anode o ka neʻe kuhikuhi o ka workpiece e waiho ʻia i loko o kahi papa zinc.
Ua hoʻopau ʻo Zinc i ka ʻokoʻa: ʻaʻohe aniani galvanized hot-dip galvanizing delicate bright appearance, akā ʻo ka mānoanoa o ka zinc coating o nā ʻano galvanizing anu o ka hot-dip galvanizing he mau manawa. ʻO ke kūpaʻa corrosion Galvanized kekahi mau manawa.

ʻAʻole ʻoi aku ka nui o kēia mau mea ʻelima ma mua o 1.00%.

B No kēlā me kēia 0.01% ka emi ʻana o ka nui o ka carbon content, ʻae ʻia ka nui o ka manganese e hoʻonui i ka 0.06%, akā ʻaʻole hiki ke kiʻekiʻe ma mua o 1.35%.

A ʻO ka lōʻihi liʻiliʻi o ka lōʻihi 2in. (50mm) e hoʻoholo ʻia e kēia ʻano kumu:

e=625000(1940)A^0.2/U^0.9

e = ka lōʻihi liʻiliʻi o ka anana 2in. (50mm), ka pākēneka i hoʻopuni ʻia i ka 0.5% kokoke loa;

A = helu ʻia e like me ke anawaena o waho o ka paipu inoa a i ʻole ka laula inoa o ka hāpana tensile a me kona mānoanoa pā i kuhikuhi ʻia, a hoʻopuni ʻia i kahi kokoke loa o ka hāpana tensile o 0.01 in.2 (1 mm2), a Hoʻohālikelike ʻia me 0.75in.2 (500mm2), ʻoi aku ka liʻiliʻi.

U = ka ikaika tensile palena iki, psi (MPa).

B No nā hui like ʻole o nā nui like ʻole o nā hōʻike hoʻāʻo tensile a me ka ikaika tensile haʻahaʻa i kuhikuhi ʻia, hōʻike ʻia ka elongation haʻahaʻa i koi ʻia ma ka Papa X4.1 a i ʻole ka Papa X4.2, e like me kona kūpono.
