ʻO ka mālama a me ka ʻae ʻana no ke kūʻai ʻana

ʻO nā mea maka o nā paipu kila welded maʻamau ka hao kalapona haʻahaʻa, haʻahaʻa haʻahaʻa a i ʻole ke kila manganese kiʻekiʻe, a me nā mea ʻē aʻe, i hoʻohana nui ʻia i loko o nā paila, nā kaʻa, nā moku, nā puka kila māmā a me nā puka makani, nā lako, nā mīkini mahiʻai like ʻole, kiʻekiʻe- nā papa hoʻokiʻekiʻe, nā pahu, a me nā mea ʻē aʻe.

ʻO ka mālama ʻana no ke kūʻai ʻana i nā paipu kila welded:

1. E nānā i nā koina o ka mea hana, inā paha ua paʻa ka laikini ʻoihana, ka palapala hōʻoia hui, ka palapala hoʻopaʻa inoa ʻauhau, ka laikini hana a me ka hana a me nā mea hōʻoia ʻē aʻe.
2. E nānā i ka hihia, e nānā i ka hana a ka mea hoʻolako, a me ke kūlana o nā papahana i lawelawe ʻia i ka wā ma mua.
3. Aia kahi moku logistics i kūkulu pono ʻia?ʻO ke koho ʻana i kahi mea lawelawe me kahi ʻauwaʻa logistic i kūkulu ʻia e hiki ke hōʻemi i nā kumukūʻai o ka lawe ʻana, a ʻo ka mea nui e hōʻoia i ka lawe ʻana i ka manawa.
4. ʻO ka lawelawe ma hope o ke kūʻai aku, inā paha he ʻōnaehana hōʻoiaʻiʻo a hilinaʻi ma hope o ke kūʻai aku, a pono e hoʻoholo ʻia nā pilikia o ka maikaʻi i ka ʻae ʻana i nā waiwai a me ka hoʻohana ʻana i ka manawa kūpono.

Nā pae hoʻoholo no nā paipu kila welded:

1. E nānā inā paʻa nā mea hōʻoia maikaʻi e like me ka palapala hōʻoia o ka huahana, manual material, a me ka puke hōʻoia maikaʻi.
2. E nānā i ke ʻano o ka paipu welded, maʻemaʻe a palahalaha ka ʻili, paʻa ka weld seam me ka ʻole o nā burrs, ʻaʻohe ʻāʻī ʻaila, ʻaʻohe extrusion deformation, a palahalaha ke keʻa.
3. E hoʻohana i ka micrometer e nānā inā ʻo ke anawaena o waho a me ka mānoanoa o ka pā o ka paipu welded e hoʻokō i nā koi, a ʻaʻole i ʻoi aku ka ʻokoʻa o ka mānoanoa o ka paia ma mua o 3% -5%.
4. E hoʻohana i kahi mea ʻike kīnā e hana i ka ʻike kīnā ʻole ma nā paipu welded.
5. E hana i ka ho'āʻo ikaika tensile e like me nā koi, e kulou i ka paipu welded 30 degere, a ʻaʻohe māwae ma ka piko.
