ʻO nā paipu metala nā paipu metala kahi e holo ai nā uwea uila a me nā kaula

ʻO nā paipu metala nā paipu metala kahi e holo ai nā uwea uila a me nā kaula.Hāʻawi ia i ka pale nui i nā uwea a me nā kaula mai ka pōʻino a me nā hopena.
Hāʻawi ʻo Henfen i nā paipu conduit maikaʻi i hoʻopaʻa ʻia i ka zinc coated, wela wela i loko a i waho.Hana ʻia i BS 4568 EN-BS31-1940.
Eia kekahi, hāʻawi ʻo Henfen i kahi ākea o nā mea hoʻonaninani metala.
Hāʻawi ʻo Henfen i ʻelua mau ʻano paipu uʻi uea maʻamau: ka maʻamau Pelekane a me ka maʻamau ʻAmelika.ʻO nā kūlana Pelekane nui ʻo BS4568 a me BS31-1940.ʻO ka nui ka nui o 20mm, 25mm, 32mm.Hiki ke wili ʻia kēia mau paipu kila, akā pono e hoʻolohe i ka hana hana.Ma hope o ke kuʻi ʻana, pono e hoʻomaʻamaʻa ʻia ka paipu galvanized, inā ʻaʻole e hoʻopilikia ʻia ka maikaʻi, a hiki mai ka blistering koʻikoʻi a i ʻole ka ʻōpala.Hoʻohana nui ʻia nā paipu Galvanized no ka pale ʻana i nā uea a me nā kaula.Hoʻohana ka hapa nui o nā hale kahiko i nā paipu galvanized.I kēia manawa, hoʻohana ʻia ka paipu galvanized no ke kinoea a me ka wela.
He aha nā ʻano o ka paipu galvanized?
1. ʻO ke kumu kūʻai haʻahaʻa haʻahaʻa: ʻO ke kumukūʻai anti-rust o ka hot-dip galvanizing he haʻahaʻa ma mua o nā pena a me nā uhi ʻē aʻe, a he haʻahaʻa loa ke kumukūʻai.
2. Paʻa: ʻO ka ʻili o ka paipu kila galvanized wela loa, ʻaʻahu like ka papa zinc, ʻaʻohe leakage, ʻaʻohe kulu, adhesion ikaika a me ke kūpaʻa ikaika.Ua piʻi aʻe ke kaiapuni suburban, a hiki ke mālama ʻia ka mānoanoa anti-corrosion maʻamau maʻamau ma mua o 50 mau makahiki me ka mālama ʻole.Ma nā kūlanakauhale a i ʻole ma waho, hiki ke mālama ʻia ka papa anti-corrosion maʻamau no kahi 20 mau makahiki me ka hoʻoponopono ʻole.
3. ʻO ka hilinaʻi maikaʻi: ʻO ka ʻili o ka paipu galvanized i hui pū ʻia me ke kila, a ua hoʻokumu ʻia kahi paipu kila ma luna o ke kila, no laila ʻoi aku ka hilinaʻi o ka paʻa.
4. He paʻakikī ko ka uhi: ʻo ka zinc coating e hana i kahi ʻano metallographic kūikawā, hiki ke pale aku i ka pōʻino mechanical i ka wā o ka lawe ʻana a me ka hoʻohana ʻana.
5. Palekana holoʻokoʻa: Hiki ke hoʻopaʻa ʻia kēlā me kēia ʻāpana kālā, hiki ke pale pono ʻia nā ʻāpana, nā kihi ʻoi a me nā wahi huna.
6. E mālama i ka manawa a me ka manpower: ʻOi aku ka wikiwiki o ke kaʻina hana galvanizing ma mua o nā ʻano hana hana uhi ʻē aʻe, hiki ke pale i ka manawa i koi ʻia no ka pena ʻana ma ke kahua kūkulu ma hope o ke kau ʻana.
