Hoʻokaʻawale
Wahi a nā ʻano hana, hiki ke hoʻokaʻawale ʻia nā paipu kila i ʻelua mau ʻāpana: nā paipu kila ʻole a me nā paipu kila welded.ʻO nā paipu kila welded i kapa ʻia nā paipu welded no ka pōkole.
Hiki ke hoʻokaʻawale ʻia nā paipu kila ʻole i loko o nā paipu wili wela, nā paipu huki anu, nā paipu kila pololei, nā paipu hoʻonui wela, nā paipu wili anu, a me nā paipu extruded e like me nā ʻano hana.
Hana ʻia nā paipu kila maʻemaʻe me ke kila kalapona kiʻekiʻe a i ʻole ke kila kila, a hiki ke ʻōwili wela a i ʻole ka ʻōwili anu (huki).
Hoʻokaʻawale ʻia nā paipu kila welded i nā paipu i hoʻoheheʻe ʻia i ka umu, nā paipu hoʻoheheʻe uila (kuʻi kūʻē) paipu, a me nā paipu arc welded ma muli o kā lākou mau kaʻina hana kuʻi.Ma muli o ko lākou mau ʻano kuʻi ʻokoʻa, ua māhele ʻia lākou i nā paipu wili wili pololei a me nā paipu wiliwili spiral.Ma muli o ko lākou ʻano hopena, ua hoʻokaʻawale ʻia lākou i nā paipu wili wili a me nā paipu welded kūikawā (square, flat, etc.).
Hoʻokumu ʻia nā paipu kila welded e ka wiliwili ʻana i nā pā kila i ʻōwili ʻia i loko o nā ʻano tubular me ka ʻūhā a i ʻole nā hili spiral.Ma nā ʻano hana hana, ua māhele ʻia lākou i nā paipu kila welded no ka lawe ʻana i ka wai kahe haʻahaʻa, nā paipu kila welded spiral, nā paipu kila i ʻōwili ʻia, a me nā paipu uila uila.Hiki ke hoʻohana ʻia nā paipu kila maʻemaʻe i nā ʻoihana like ʻole e like me nā pipeline kinoea wai a me nā pipeline gas.Hiki ke hoʻohana ʻia nā paipu welded no nā pipeline wai, pipeline gas, pipeline hoʻomehana, pipeline uila, etc.
