Paipu kila ERW
ʻO ka paipu ERW (paipu welded resistance uila) a me ka paipu CDW (paipu welded i huki anu ʻia) ʻelua mau kaʻina hana like ʻole no nā paipu kila welded.
1. Kaʻina hana
| Nā mea hoʻohālikelike | Paipu ERW (paipu wili ʻia me ke kū'ē uila) | Paipu CDW (paipu i hoʻopaʻa ʻia i ke anu) |
| Inoa piha | Paipu Welded Pale Uila | Paipu Welded i huki anu ʻia |
| Ke kaʻina hana | Hoʻomehana ʻia ka lihi o ka papa kila e ke au alapine kiʻekiʻe a hoʻopaʻa ʻia a hoʻopaʻa ʻia i ke ʻano | Hoʻopili mua ʻia i loko o nā paipu, a laila huki anu ʻia (lāʻau hoʻololi anu) |
| ʻAno hana kuʻihao | Kuʻihao Kū'ē Alapine Kiʻekiʻe (HFW/ERW) | Hoʻohana pinepine ʻia ka ERW a i ʻole ka argon arc welding (TIG) no ka hoʻopili ʻana. |
| Ka hana ʻana ma hope | Ka nui pololei a me ka ʻoki ʻana ma hope o ka hoʻoheheʻe ʻana | Ka hoʻopau ʻana i ke kaha kiʻi anu (ʻōwili anu) ma hope o ka hoʻoheheʻe ʻana |
2. Nā ʻano hana
Paipu ERW
Pololei Ana: Nui (± 0.5% ~ 1% ke anawaena o waho)
ʻAno o ka ʻili: Ua maopopo iki ka weld a pono e hoʻopili ʻia
Nā waiwai mechanical: Pili ka ikaika i ka mea makua, a hiki ke palupalu ma kahi i hoʻopili ʻia
Koena kaumaha: Haʻahaʻa (mālama wela maʻalahi wale nō ma hope o ka hoʻoheheʻe ʻana)
Paipu CDW
Pololei Ana: kiʻekiʻe loa (i loko o ±0.1mm, kūpono no nā kumu kikoʻī)
ʻAno o ka ʻili: ʻili laumania, ʻaʻohe unahi oxide (wili ʻia ma hope o ke kaha kiʻi anu)
Nā waiwai mechanical: paʻakikī hana anu, hoʻonui ʻia ka ikaika e 20% ~ 30%
Koena kaumaha: kiʻekiʻe (pono ka annealing e hoʻopau i ke kaumaha huki anu)
3. Nā hiʻohiʻona noi
ERW: nā paipu ʻaila/kinoea, nā paipu kūkulu hale (scaffolding), nā paipu wai haʻahaʻa (GB/T 3091)
CDW: nā cylinders hydraulic, nā ʻāpana mīkini kikoʻī (e like me nā lima bearing), nā ʻau hoʻoili kaʻa (nā wahi me nā koi pololei dimensional kiʻekiʻe)
Nā kūlana maʻamau o nā ʻano
ERW: API 5L (paipu paipu), ASTM A53 (paipu kūkulu), EN 10219 (paipu welded maʻamau ʻEulopa)
CDW: ASTM A519 (paipu kikoʻī anu i huki ʻia), DIN 2391 (paipu kikoʻī kiʻekiʻe maʻamau Kelemania)
Paipu CDW = paipu ERW + kaha kiʻi anu, me nā ana pololei a me ka ikaika kiʻekiʻe, akā ʻoi aku ke kiʻekiʻe o nā kumukūʻai.
He kūpono ka paipu ERW no nā kumu kūkulu maʻamau, ʻoiai hoʻohana ʻia ka paipu CDW ma ke kahua o nā mīkini kikoʻī kiʻekiʻe.
Inā pono e hoʻomaikaʻi hou ʻia ka hana o ka paipu CDW, hiki ke hoʻohui ʻia ka mālama ʻana i ka annealing (e hoʻopau i ke kaumaha hana anu).
