Paipu Welded Galvanized
I mea e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion o nā paipu kila, ua galvanized nā paipu kila maʻamau.Hoʻokaʻawale ʻia nā paipu kila galvanized i ʻelua ʻano: hot-dip galvanizing a me electro-galvanizing.He mānoanoa ka papa galvanizing wela, he haʻahaʻa ke kumukūʻai o ka electro-galvanizing, a ʻaʻole maʻalahi ka ʻili.
ʻO ka paipu hoʻoheheʻe ʻia o ka oxygen: Hoʻohana ʻia ma ke ʻano he paipu hoʻoheheʻe ʻana i ka oxygen, ma ke ʻano he mau paipu kila liʻiliʻi liʻiliʻi, me nā kikoʻī ʻewalu mai ka 3/8 a 2 iniha.Hana ʻia ʻo 08, 10, 15, 20 a i ʻole 195-Q235 ka mea kila, i mea e pale ai i ka corrosion, pono ia e hoʻokō i ka mālama aluminizing.
Hoʻohana ka hapa nui o nā hale kahiko i nā paipu galvanized.ʻO nā paipu hao i hoʻohana ʻia no ke kinoea a me ka hoʻomehana ʻana he paipu galvanized nō hoʻi.Hoʻohana ʻia nā paipu Galvanized e like me nā paipu wai.Ma hope o kekahi mau makahiki o ka hoʻohana ʻana, nui ka ʻōpala a me ka lepo i hana ʻia i loko o nā paipu, a ʻo ka wai melemele e kahe ana ʻaʻole e hoʻohaumia wale i nā mea maʻemaʻe., A hui pū ʻia me nā hua bacteria e hānau ana ma ka paia o loko ʻaʻole like, ʻo ka ʻōpala ke kumu o ka nui o ka metala kaumaha i loko o ka wai, kahi e hoʻopilikia nui ai i ke olakino kanaka.I nā makahiki 1960 a me 1970, ua hoʻomaka nā ʻāina i kūkulu ʻia i ka honua e hoʻomohala i nā ʻano paipu hou a pāpā mālie i nā paipu galvanized.ʻEhā mau ʻoihana a me nā komisina me ka Ministry of Construction of China i hoʻopuka pū i kahi palapala e wehewehe ana ua pāpā ʻia nā paipu galvanized mai ka makahiki 2000.ʻAʻole hoʻohana ʻia nā paipu galvanized no nā paipu wai anuanu ma nā kaiāulu hou i kūkulu ʻia ma hope o 2000, a hoʻohana ʻia nā paipu galvanized no nā paipu wai wela ma kekahi mau kaiāulu.

Hoʻokaʻawale ʻia nā paipu kila galvanized i nā paipu galvanized anu a me nā paipu galvanized wela.Ua pāpā ʻia ka mea mua, a ua hoʻolaha ʻia ka mea hope e ka mokuʻāina e hoʻohana no ka manawa.
Paipu galvanized wela
ʻO ka paipu galvanized wela e hana i ka metala i hoʻoheheʻe ʻia a me ka matrix hao e hana i kahi ʻāpana alloy, i hui ʻia ka matrix a me ka uhi.ʻO ka galvanizing wela ka hoʻopili mua ʻana i ka paipu kila.I mea e wehe ai i ka hao oxide ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia i loko o kahi pahu o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka hui ʻana o ka wai o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i In ka pahu hoʻopaʻa wela wela.Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.
Paipu galvanized anu
Cold galvanizing mea electro-galvanizing, a me ka nui o ka galvanizing mea uuku loa, wale 10-50g/m2, a me kona corrosion kū'ē i oi aku ka hewa ma mua o ka wela-luu galvanized paipu.ʻAʻole hoʻohana ka hapa nui o nā mea hana paipu galvanized maʻamau i ka electro-galvanized (cold plating) i mea e hōʻoia ai i ka maikaʻi.ʻO kēlā mau ʻoihana liʻiliʻi wale nō me nā mea liʻiliʻi a me nā mea hana kahiko e hoʻohana i ka electro-galvanization, a ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o kā lākou kumukūʻai.Ua hoʻolaha kūkala ke Keʻena ʻOihana e hoʻopau ʻia nā paipu anu me nā ʻenehana kahiko, a ʻaʻole e ʻae ʻia nā paipu wai a me ke kinoea i kēia mua aku.
Paipu kila galvanized wela: Ke komo nei ka matrix paipu kila i ka hopena kino a me ke kemika me ka hoʻoheheʻe hoʻoheheʻe hoʻoheheʻe ʻia e hana ai i kahi papa hoʻoheheʻe zinc-hao me ka hale paʻa.Hoʻohui ʻia ka papa ʻaina me ka ʻāpana zinc maʻemaʻe a me ka matrix paipu kila.No laila, ikaika kona pale ʻana i ka corrosion.
Piula kila galvanized anu:ʻO ka papa zinc he papa electroplated, a ua hoʻopaʻa kūʻokoʻa ka papa zinc a me ka substrate paipu kila.He lahilahi ka papa zinc, a pili wale ka papa zinc i ka substrate paipu kila a maʻalahi ke hāʻule.No laila, ʻilihune kona pale ʻana i ka corrosion.Ma nā hale hou i kūkulu ʻia, pāpā ʻia ka hoʻohana ʻana i nā paipu kila galvanized anuanu e like me nā paipu wai.
ʻO ke kaʻina hana o ke kila kila i kēia mau hana hana:
a.Hoʻomākaukau kila pōʻai;b.ʻO ka hoʻomehana;c.Hoʻopiʻi wela;d.E ʻoki i ke poʻo;e.Pickling;f.wili;g.Lubrication;h.ʻO ka hana ʻōwili anuanu;i.Degreasing;j.Hoʻoponopono wela wela;k.Hoʻopololei;l.ʻOki i ka paipu;m.Pickling;n.Hōʻike huahana.
Hāʻawi wale i ke kaʻina hana maʻamau, a ʻo nā mea kikoʻī e pili ana i nā mea huna o kēlā me kēia mea hana
1. ʻO ka brand a me ka haku mele
ʻO ka papa a me ka hana kemika o ke kila no nā paipu kila galvanized e hoʻokō me ka pae a me ka hoʻohui kemika o ke kila no nā paipu ʻeleʻele i kuhikuhi ʻia ma GB 3092.
2. Hana hana
ʻO keʻano hana o ka paipuʻeleʻele (ka umu ahi a iʻole ka uila uila) i kohoʻia e ka mea hana.Hoʻohana ʻia ka galvanizing wela no ka galvanizing.
3. Nā hui kaula a me ka paipu
3.1 No nā paipu kila galvanized i hāʻawi ʻia me nā kaula, pono e hana ʻia nā kaula ma hope o ka galvanizing.Pono ke kaula e hoʻokō i nā lula YB 822.
3.2 Pono nā hui paipu kila i ka YB 238;Pono nā hui paipu hao malleable e hoʻokō me YB 230.
4. Nā waiwai mīkini ʻO nā mea mechanical o nā paipu kila ma mua o ka galvanizing e kūpono i nā koi o GB 3092.
5. Pono e ho'āʻoʻia keʻano likeʻole o ka'āpana galvanized .'A'ole e 'ula'ula ka la'ana paipu kila ma hope o ka ho'okomo 'ia 'ana i loko o ka solution keleawe sulfate no 5 mau manawa.
6. ʻO ka hoʻāʻo ʻana i ke anu ʻO ka paipu kila galvanized me ke anawaena inoa ʻaʻole iʻoi aku ma mua o 50mm pono e hoʻokō ʻia i kahi hoʻokolohua anu.He 90° ka huina kulou, a he 8 manawa ke anawaena o waho ka radius kulou.ʻAʻohe mea hoʻopiha i ka wā o ka hoʻāʻo ʻana, a pono e kau ʻia ka weld o ka hāpana ma waho a i ʻole ʻaoʻao o luna o ke kuhikuhi ʻana.Ma hope o ka hoʻāʻo ʻana, ʻaʻohe māwae a me ka ʻili ʻana o ka papa zinc ma ka hāpana.
7. ʻO ka hoʻāʻo ʻana i ka wai Pono e hoʻokō ʻia ka hoʻāʻo ʻana o ka wai ma ka clarinet.Hiki ke hoʻohana ʻia ka ʻike hemahema ʻo Eddy i kēia manawa ma kahi o ka hoʻāʻo ʻana i ka wai.ʻO ke kaomi hoʻāʻo a i ʻole ka nui o ka laʻana hoʻohālikelike no ka hoʻāʻo ʻana i kēia manawa e hoʻokō i nā koi o GB 3092.
