Wela -Dip Galvanizing

ʻO ka paipu kila Galvanized kahi ʻano paipu kila i uhi ʻia me kahi papa pale o ka zinc ma kona ʻili. Hoʻohana ʻia ka zinc coating ma ke ʻano he pale kino a ma ke ʻano he anode mōhai, ʻo ia hoʻi inā ʻoki ʻia ka uhi ʻana, e ʻino mua ka zinc a puni e pale i ke kila o lalo mai ka hoʻonā ʻana. ʻO kēia ka mea e ʻoi aku ka lōʻihi o nā paipu galvanized i loko o nā wahi ʻūlū a i ʻole nā ​​​​kino.
ʻElua mau ala galvanizing maʻamau:

• Electro -galvanizing- ʻO ka papa zinc lahilahi, ka ʻili maʻemaʻe, ka hoʻopili maikaʻi ʻana, akā ʻoi aku ka haʻahaʻa o ka pale ʻana i ka corrosion.
• -hoʻopuu wela (HDG)– Hoʻokomo ʻia ka paipu kila i hoʻomaʻemaʻe ʻia i loko o ka zinc hoʻoheheʻe ʻia ma 450–500 degere, e hana ana i kahi zinc-iron alloy layer metallurgically i hoʻopaʻa ʻia i ke kila a me ka papa luna o ka zinc maʻemaʻe. Hiki ke mānoanoa o ka uhi mai 35 μm a hiki i 650 μm, e hā'awi ana i ke kū'ē corrosion maika'i a me ke ola lawelawe e like me ka electro-galvanizing.

Ma muli o kona mānoanoa, ʻaʻahu, a paʻa paʻa paʻa i ka zinc, hoʻohana nui ʻia ka paipu hao hao wela i ka lako wai, ka hāʻawi kinoea, nā mea hana petrochemical, ke kūkulu ʻana, nā pale, a me nā hale o waho, e hāʻawi ana i kahi hopena palekana - lōʻihi.

• ASTM A123– ʻO Zinc (Hot{0}}Dip Galvanized) i nā mea hao a me nā mea hao
• ASTM A53 (Koho Galvanized)– Seamless a welded galvanized paipu kila
• BS 1387– ʻO nā paipu hao hao wela no ka wai, ke kinoea, a me ka mahu
• GB/T 3091– ʻO nā paipu hao hao i hoʻopaʻa ʻia no ka lawe ʻana i ka wai haʻahaʻa

• Pale Pale- Hoʻokaʻawale ka Zinc coating i ke kila mai ka wai a me ka oxygen.
• Palekana Cathodic- Hoʻopili maikaʻi ʻia ka Zinc, e pale ana i ke kila i ʻike ʻia ma nā ʻōpala a i ʻole nā ​​kihi.
• Hoʻopaʻa Layer Alloy– Hāʻawi ka Zinc-iron alloy i ka hoʻopili maikaʻi ʻana a me ke kūpaʻa ʻana i ka ʻili a i ʻole ka ʻili.

• Hoʻonui i ke ola lawelawe- Ma nā kūlana lewa maʻamau, hiki i nā paipu galvanized ke mau 30-50 mau makahiki; i loko o ka ʻenehana a i ʻole nā ​​kahakai, 15-20 mau makahiki o ka pale ʻana he mea maʻamau.
• Hoʻopiha piha– Hāʻawi i ka pale like ʻole ma luna o ka paipu holoʻokoʻa, me nā wili, nā kihi, a me nā wahi paʻakikī e hiki ai-
• Kumukuai -Hiki– Hoʻokahi-hoʻokahi manawa hāʻawi galvanizing i nā ʻumi makahiki o ka palekana, e hōʻemi ana i ka mālama a me ka pena hou ʻana i nā kumukūʻai i ke ola o ka lawelawe.
• Paʻa Kiʻekiʻe– ʻAʻole kūpaʻa ka ʻāpana zinc metala -iron i ka abrasion a me ka hopena mechanical i ka wā o ka lawelawe ʻana, ka hoʻouna ʻana, a me ke kau ʻana.
• Pilikia -kaiaola– Hiki ke hoʻohana hou ʻia ka Zinc, a ʻoi aku ka haʻahaʻa o ke kaiapuni o ka hoʻoheheʻe wela -pili i nā ʻōnaehana pena.
• Nānā maʻalahi- Hiki ke hōʻoia maʻalahi i ka mānoanoa o ka uhi ʻana a me ka maikaʻi o ka ʻili e ka nānā ʻana a i ʻole nā ​​ana mānoanoa.

• Nā Papahana Kaona: Ka wai, nā paipu kinoea, nā ʻōnaehana wai
• Hana Hana: Scaffolding, guardrails, structural supports
• Mahele ikehu: Petrochemical, kinoea maoli, hoʻoili mahu
• ʻOihana a me ka lawe ʻana: Nā alahaka, nā pā alanui, nā hale alanui
• Mahiai & Hana: Pūnaehana wai, hale waihona, pā

Ma Octal Pipe, hana ʻia nā paipu hao wela -ma lalo o nā ʻōnaehana QA/QC koʻikoʻi:

• ʻO ka hoʻāʻo ʻana i ka mānoanoa o ka uhi ʻana (μm a i ʻole g/m²) no nā kūlana ASTM/BS/GB
• Adhesion, lokahi, a me ka ho'āʻo paʻakai
• Nānā piha a me ka nānā ʻana e hōʻoiaʻiʻo i ka pau ʻole o ka hemahema
• Hoʻolako maʻalahi me ka laulā o nā māka kila, nā anawaena, a me nā lōʻihi
• Hoʻopiha i nā palapala maikaʻi a me ka traceability no ka ʻae ʻana o ka papahana

• Kaʻina hana: Kalu ana iloko o ka zinc hehee ma 450–500 degere
• Hoʻopili Zinc: 35–650 μm
• Nui: ½″ – 20″ (DN15 – DN500)
• Nā kūlana: ASTM A123, ASTM A53, BS 1387, GB/T 3091
• Nā noi: Wai, kinoea, kūkulu, ikehu, hana
• Ola lawelawe: 20–50 makahiki ma muli o ke kaiapuni
