He aha ka ʻokoʻa ma waena o ke koʻokoʻo, ka Tube, a me ka Pipe i ke kila kila?

1. Nā Inoa Huahana a me nā Wehewehena (Hoʻohālikelike Pelekane-Kina)

Inoa Pelekania Inoa Kina Wehewehena a me nā ʻano
Pōʻai 不锈钢圆钢 (Stainless Steel Round) ʻO ka maʻamau, pili ia i nā kaola poepoe paʻa i ʻōwili wela ʻia, hoʻoheheʻe ʻia, a i ʻole i huki anu ʻia. ʻO ka maʻamau he ≥10mm ke anawaena, hoʻohana ʻia no ka hana hou aku.
Lāʻau 不锈钢棒材 (Stainless Steel Rod) Hiki ke kuhikuhi i nā koʻokoʻo poepoe, nā koʻokoʻo hex, a i ʻole nā ​​koʻokoʻo huinaha. ʻO nā kaola paʻa liʻiliʻi ke anawaena (e laʻa, 2mm–50mm) me ka pololei kiʻekiʻe, kūpono no nā mea hoʻopaʻa, nā ʻāpana mīkini kikoʻī, a pēlā aku.
Palapala 不锈钢薄板 (Pepa kila kila) ʻO ka maʻamau he ≤6mm ka mānoanoa, ʻo ka hapa nui he ʻōwili anu, me ka ʻili laumania. Hoʻohana ʻia i ke kuhikuhipuʻuone, nā mīkini hana, nā lako kīhini, a pēlā aku.
Pā 不锈钢中厚板 ʻO ka maʻamau he ≥6mm ka mānoanoa, ʻo ka hapa nui i ʻōwili wela ʻia. Kūpono no nā kīʻaha kaomi, nā ʻāpana kūkulu, nā noi ʻoihana hana kaumaha.
ʻŌmole 不锈钢管（装饰管) ʻO ka maʻamau, pili ia i nā paipu kūkulu, mīkini, a i ʻole nā ​​​​paipu hoʻonaninani. Hiki ke hoʻopaʻa ʻia a humuhumu ʻole ʻia paha. Kūleʻa i ka pololei o ke ana a me ke ʻano, e laʻa, no nā lako a i ʻole nā ​​​​​​alanui.
Paipu 不锈钢管（工业管）(Stainless Steel Pipe – Industrial) Hoʻohana pinepine ʻia no nā paipu ʻoihana, e like me ka lawe ʻana i ke wai, nā mea hoʻololi wela, nā paila. Hoʻokūpaʻa i ka mānoanoa o ka paia, ka helu kaomi, a me nā kikoʻī maʻamau (e laʻa, SCH10, SCH40).

Māhele Paʻa Lua Ka Manaʻo Nui no ka Noi ʻana Nā ʻano hana
Pōʻai/Koʻokoʻo ✅ ʻAe ❌ ʻAʻole Mīkini, hoʻoheheʻe, mea hoʻopaʻa ʻŌwili wela, hana ʻana, kaha anu, wili ʻana

  • Pōʻai= ʻO ka pā poepoe no ke kumu maʻamau, no ka hana ʻana maʻalahi

  • Lāʻau= Kaʻa liʻiliʻi a ʻoi aku ka pololei

  • Palapala= Huahana pālahalaha lahilahi (≤6mm)

  • Pā= Huahana pālahalaha mānoanoa (≥6mm)

  • ʻŌmole= No ka hoʻohana nani/kūkulu

  • Paipu= No ka lawe ʻana i ka wai (i helu ʻia e ke kaomi/maʻamau)
