ʻElua ʻano o nā paipu kila maʻemaʻe ʻole, ʻo ka galvanizing hot-dip (hot-dip galvanizing) a me ke anuanu-dip galvanizing (electro-galvanizing). Hot-dip galvanizing i ka mānoanoa galvanized papa, i loaʻa i nā pono o ka lole hoʻopaʻa lole, ikaika adhesion, a me ka lōʻihi lawelawe ola. Eia naʻe, he haʻahaʻa ke kumukūʻai o ka electro-galvanizing, ʻaʻole maʻalahi ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o nā paipu galvanized wela. Pehea e nānā ai i ka maikaʻi o ka paipu kila seamless galvanized?

E like me nā koi o ka maʻamau, ua kuhikuhi ka mea hana paipu galvanized i ka nānā ʻana o nā ana geometric o ka paipu seamless galvanized ka nui o ka mānoanoa o ka pā, ka anawaena o waho, ka lōʻihi, ka curvature, ovality a me ke ʻano hope o ka paipu seamless galvanized.

1. Nānā mānoanoa o ka pā

ʻO ka mea hana i hoʻohana ʻia no ka nānā ʻana i ka mānoanoa o ka paia he micrometer. I ka nānā ʻana, e ana i ka mānoanoa o ka pā o ka paipu galvanized me ka micrometer. Ma mua o ka nānā ʻana, e hōʻoia mua inā aia ka palapala hōʻoia o ka micrometer i loko o ka manawa kūpono, a nānā inā pili ka micrometer me ke kūlana zero a inā hiki ke loli. Pono ʻole ka ʻili o ke ana ʻana i nā ʻōpala a me nā wahi ʻōpala, a hiki ke hoʻohana ʻia ma hope o ka hala ʻana o ka hoʻāʻo. I ka nānā ʻana, e hoʻopaʻa i ka bracket micrometer me ka lima hema a e hoʻohuli i ka huila hoʻohiwahiwa me ka lima ʻākau. Pono e kūlike ke koʻokoʻo wili me ke anawaena o ke ana ana, a ʻaʻole i emi iho ke ana o ka ʻili ma lalo o 6 mau kiko. Inā ʻike ʻia ka mānoanoa o ka pā ʻaʻole kūpono, pono e kaha ʻia.

2. ʻO ke anawaena o waho a me ka nānā ovality

ʻO nā mea hana i hoʻohana ʻia no ke anawaena o waho a me ka nānā ʻana i ka ovality ka nui o nā calipers a me nā calipers vernier. I ka wā o ka nānā ʻana, e ana i ke anawaena o waho o ka paipu galvanized i kēlā me kēia me kahi caliper kūpono. Ma mua o ka nānā ʻana, e hōʻoia mua inā aia ka palapala hōʻoia o ka caliper i loko o ka manawa kūpono, a e nānā i ka caliper i hoʻohana ʻia me kahi caliper vernier e ʻike ai inā aia kekahi ʻōpala a ʻōpala paha ma ka ʻili ana, a hiki ke hoʻohana wale ʻia ma hope o ka hala ʻana o ka. hoao. I ka wā o ka nānā ʻana, pono e kū pono ka caliper i ke koʻi o ka paipu galvanized, a ʻo ka lohi o ka paipu galvanized. Inā ʻike ʻia he nui a liʻiliʻi paha ke anawaena o waho o ka ʻāpana kahi i ana ʻia ai, pono e kaha ʻia.

3. Nānā lōʻihi

ʻO ka mea hana i hoʻohana ʻia no ka nānā ʻana i ka lōʻihi o ka paipu seamless galvanized he lipine kila. Ke ana i ka lōʻihi, pili ka "O" o ka lipine me kekahi kihi o ka paipu galvanized, a laila hoʻopaʻa ʻia ka lipine i kokoke ka ʻaoʻao unahi i ka ʻili o ka paipu galvanized. ʻO ka lōʻihi o ka lipine ma kekahi ʻaoʻao o ka paipu galvanized ka lōʻihi o ka paipu galvanized.

4. Kulou ka nana ana o ka paipu galvanized

ʻO ka nānā ʻana i ka degere bending o ka paipu galvanized ka mea nui e nānā i ka degere bending o ka lōʻihi holoʻokoʻa o ka paipu galvanized a me ke degere o ke kulou ʻana i kēlā me kēia mika. ʻO nā mea hana i hoʻohana ʻia ʻo ia ka ruler pae, feeler gauge a me ke aho lawaiʻa. I ka ana ana i ka huina pi'o o ka paipu galvanized, e hoohana i ke aho lawai'a e hoolike i kekahi welau o ka paipu huinahalike, a laila e hoopaa i ke aho i kokoke loa kekahi aoao o ke aho i ka ili o ka paipu hao, a laila. e hoʻohana i ka mea hoʻoheheʻe manaʻo e ana i ka ʻili o ka paipu galvanized a me ka iʻa. ʻO ke kaawale o ka laina laina, ʻo ia hoʻi, ka lōʻihi o ka paipu uʻi galvanized.

Manaʻo kōkua: Galvanized 'o ia hoʻi, ua uʻi ʻia ka ʻili o ka paipu kila, a he paipu wili paha ia a i ʻole he paipu ʻole. ʻO kekahi mau paipu kila welded i hana ʻia e ka ʻōwili pololei ʻana i nā ʻāpana galvanized, a ua hana ʻia kekahi me nā paipu kila ʻole a laila galvanized.
