ʻokoʻa ma waenapaipu pre-galvanizedaPipa hao hao wela-DIP
1. ʻOkoʻa i ke kaʻina hana: Hot-dip galvanized pipe is galvanized by immerging the steel pipe in molten zinc, akā.paipu pre-galvanizedua uhi ʻia me ka zinc ma ka ʻili o ka ʻili kila ma ke kaʻina hana electroplating.
2. Nā ʻokoʻa ʻokoʻa: ʻO ka pipe galvanized Hot-dip he huahana tubular, ʻoiai ʻo ka paipu kila pre-galvanized he huahana huki me ka laulā nui a me ka mānoanoa liʻiliʻi.
3. Nā noi likeʻole: Hoʻohana nuiʻia nā paipu wela wela no ka laweʻana i nā wai a me nā kinoea, e like me nā paipu wai, nā paipu aila, a me nā mea'ē aʻe, aʻo nā paipu kila mua i hoʻohanaʻia no ka hanaʻana i nā mea metala likeʻole, e like me nā'āpana kaʻa, ka home. nā pūpū mea hana a pēlā aku.
4. ʻOkoʻa ka anti-corrosion hana: wela-luu puʻe hao paipu i oi aku ka anti-corrosion hana ma muli o ka mānoanoa galvanized papa, oiai galvanized kila aʻe i mea ilihune anti-corrosion hana ma muli o ka thinner galvanized papa.
5. ʻO nā kumukūʻai like ʻole: ʻo ke kaʻina hana o ka pipe galvanized hot-dip he mea paʻakikī a me ke kumukūʻai, ʻoiai ke kaʻina hana o ka paipu kila galvanized he mea maʻalahi a haʻahaʻa.
ʻO ka nānā ʻana i ka maikaʻi o ka maikaʻi o ka maikaʻi o ka paipu kila ma mua
1. Nānā hiʻona
ʻO ka pau ʻana o ka ʻili: ʻO ka nānā ʻana i ka nānā ʻana e pili ana i ka palahalaha a me ka maʻemaʻe o ka ʻili o ka paipu kila, me ka ʻike ʻole o ka zinc slag, zinc tumo, kahe e kau ana a i ʻole nā mea kīnā ʻē aʻe. Pono ka ili o ka paipu kila galvanized maikaʻi, ʻaʻohe huʻihuʻi, ʻaʻohe māwae, ʻaʻohe puʻupuʻu zinc a i ʻole ke kahe ʻana o ka zinc a me nā hemahema ʻē aʻe.
Ka waihoʻoluʻu a me ka like ʻole: E nānā inā ʻaʻahu like ʻole ka waihoʻoluʻu o ka paipu kila, a i ʻole ka mahele like ʻole o ka papa zinc, ʻoi aku hoʻi i nā hili a i ʻole nā wahi welded. He keʻokeʻo keʻokeʻo keʻokeʻo a i ʻole keʻokeʻo keʻokeʻo, ʻoiai ʻoi aku ka māmā o ke kala.
2. Ana mānoanoa Zinc
Ana Mānoanoa: Ana ʻia ka mānoanoa o ka papa zinc me ka hoʻohana ʻana i kahi ana mānoanoa i uhi ʻia (e laʻa. He hōʻailona koʻikoʻi kēia e hoʻoholo ai inā kūpono ka zinc coating i nā koi maʻamau. ʻOi aku ka mānoanoa o ka paipu hao hao wela, ʻoi aku ka maʻamau ma waena o 60-120 microns, a ʻo ka paipu kila i hoʻopaʻa ʻia ma mua o ka pae zinc ʻoi aku ka lahilahi, ma waena o 15-30 microns.
Kaona kaumaha (sampling): Ua kaupaona ʻia nā laʻana e like me ke kūlana a ua helu ʻia ke kaumaha o ka papa zinc ma kēlā me kēia ʻāpana e hoʻoholo ai i ka mānoanoa o ka papa zinc. Hoʻoholo maʻamau kēia ma ke ana ʻana i ke kaumaha o ka paipu ma hope o ka pickling.
Nā koi maʻamau: No ka laʻana, ʻo GB / T 13912, ASTM A123 a me nā kūlana ʻē aʻe i maopopo nā koi no ka mānoanoa o ka papa zinc, a ʻokoʻa paha nā koi o ka mānoanoa zinc no nā paipu kila no nā noi like ʻole.
3. Kaulike o ka papa galvanized
ʻO ka papa galvanized kiʻekiʻe he ʻano like ʻole i ke ʻano, ʻaʻohe leaka a ʻaʻohe pōʻino post plating.
ʻAʻole ʻike ʻia ka ooze ʻulaʻula ma hope o ka hoʻāʻo ʻana me ka solution copper sulfate, e hōʻike ana ʻaʻole leakage a i ʻole ka pōʻino ma hope o ka plating.
ʻO kēia ka maʻamau no nā mea galvanized kiʻekiʻe e hōʻoia i ka hana maikaʻi loa a me ke ʻano.
4. Adhesion ikaika o ka papa galvanized
ʻO ka hoʻopili ʻana o ka papa galvanized kahi hōʻailona koʻikoʻi o ka maikaʻi o ka paipu kila galvanized, e hōʻike ana i ke kiʻekiʻe o ka paʻa o ka hui ʻana ma waena o ka galvanized layer a me ka paipu kila.
ʻO ka paipu kila e hana i kahi papa huila o ka zinc a me ka hao me ka hopena galvanizing ma hope o ka hopena o ka ʻauʻau ʻauʻau, a hiki ke hoʻonui ʻia ka hoʻopili ʻana o ka papa zinc e ka ʻepekema a me ka pololei galvanizing kaʻina.
Inā ʻaʻole e hemo maʻalahi ka papa zinc i ka wā e paʻi ʻia me ka mallet rubber, hōʻike ia i ka pili maikaʻi ʻana.
