1.Metal pae
ʻO ke kaʻina hana piha ʻo ia kekahi o nā ala nui e hoʻokaʻawale i waena o nā paipu kila i hui pū ʻia apaipu kila ʻole. ʻAʻole hoʻohui ʻia nā mea wiliwili kiʻekiʻe electro-coal o nā paipu kila, no laila ʻokiʻoki loa ke alo o ka paipu kila welded. Inā hoʻohana ʻia ke ʻano o ka wili ʻana a laila hoʻohana ʻia ke kuʻi ʻana, ʻaʻole hiki ke ʻike maopopo ʻia ke hili. Hoʻopau ʻia kahi hui lānahu Yang uila kiʻekiʻe me ka ʻole o ka mālama ʻana i ka wela, kahi e ʻokoʻa loa ai ke ʻano o ke kaʻina mai nā mea makua paipu kila. Ke nānā 'ia ka ferrite a me ka Wigmansite, metala kumu a me ka weld zone, , hiki iā 'oe ke 'ike pono i nā paipu kila welded a me nā paipu kila ma'ema'e.
2.Corrosion ala
Ma ke kaʻina hana o ka hoʻohana ʻana i ke ʻano corrosion e hoʻokaʻawale i waena o nā paipu kila welded apaipu kila ʻole, pono e poni ia na hili o na paipu kila welded i hanaia. Ma hope o ka pau ʻana o ka wili ʻana, pono e ʻike ʻia nā ʻāpana o ka wili ʻana, a laila e hoʻonani ʻia nā maka hope me ka sandpaper ma nā welds. A e hoʻohana i ka 5% nitric acid alcohol solution e mālama i ka maka hope. Inā ʻike ʻia kahi weld maopopo, hiki ke hōʻoia i ka paipu kila he paipu kila welded.
3. Hoʻokaʻawale i nā paipu kila welded a me nā paipu kila ʻole e like me ke kaʻina hana
I ka hoʻokaʻawale ʻana ma waena o nā paipu kila welded a me nā paipu kila ʻole e pili ana i ke kaʻina hana, ua hana ʻia nā paipu kila welded ma o nā ʻenehana e like me ke anuanu a me ka extrusion, e pili ana i ke kaʻina hana. hoʻohana ʻia nā kaʻina hana paipu welded i ka wā e hoʻoheheʻe ʻia ai, e hoʻokumu ʻia ka hoʻoheheʻe ʻana i ka paipu spiral a me ka hoʻoheheʻe ʻia ʻana o ke kuʻi pololei, ka mea e hana ai i nā paipu kila pōʻai, nā paipu kila huinahā, nā paipu kila oval, nā paipu kila triangular, nā paipu kila hexagonal, nā paipu kila keʻano o ke kino. ʻO nā paipu kila octagonal, a ʻoi aku ka paʻakikī. Paipu kila.
4. E hoʻokaʻawale i nā paipu kila welded a me nā paipu kila ʻole e like me kā lākou hoʻohana ʻana
ʻO nā paipu kila welded he kiʻekiʻe ke kulou a me ka ikaika torsional a ʻoi aku ka nui o ka lawe ʻana i ka ukana, no laila hoʻohana nui ʻia lākou i ka hana ʻana i nā ʻāpana mechanical. No ka laʻana, hana ʻia nā paipu ʻaila ʻaila, nā ʻaukā kaʻa, nā papa paikikala, a me nā scaffolding kila i hoʻohana ʻia i ke kūkulu ʻana i nā paipu kila welded. Eia nō naʻe, hiki ke hoʻohana ʻia nā paipu kila ʻole ma ke ʻano he paipu no ka lawe ʻana i nā wai no ka mea he ʻāpana kea ko lākou a he mau ʻāpana kila lōʻihi me ka ʻole o nā humu a puni.
