Paipu kila welo a me ka paipu kila ʻole

ʻO ka paipu kila maʻemaʻe ka lōʻihi o ke kila me ka ʻāpana kea a ʻaʻohe humu a puni. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me nā koʻokoʻo ʻaila hinu, nā pahu hoʻoili automotive, nā papa paikikala, a me nā scaffolding kila i hoʻohana ʻia i ke kūkulu ʻana. ʻO ka hoʻohana ʻana i nā paipu kila no ka hana ʻana i nā ʻāpana pōʻai hiki ke hoʻomaikaʻi i ka hoʻohana ʻana i nā mea, hoʻomaʻamaʻa i nā kaʻina hana, mālama i nā mea hana a me ka manawa hana, e like me nā apo wili wili, nā lima jack, etc. I kēia manawa, hoʻohana nui ʻia nā paipu kila no ka hana ʻana. ʻO nā paipu kila he mea nui loa ia no nā mea kaua maʻamau, e like me nā pahu pū a me nā pūkuniahi, e koi ana i nā paipu kila no ka hana ʻana.
ʻO ka paipu kila welded, ʻike ʻia hoʻi he paipu welded, ua māhele ʻia i ka paipu wili wili pololei a me ka paipu wiliwili spiral. He paipu kila ia i hana ʻia e ka wiliwili ʻana i nā pā kila a i ʻole nā ʻāpana kila ma hope o ka wili ʻana a me ka hana ʻana. He maʻalahi ke kaʻina hana o nā paipu kila welded, kiʻekiʻe ka hana hana, nui nā ʻano like ʻole a me nā kikoʻī, a ua kaupalena ʻia nā kumuwaiwai, akā ʻoi aku ka haʻahaʻa o ka ikaika ma mua o nā paipu kila ʻole. ʻO nā mea noi: nā paipu lawe wai haʻahaʻa haʻahaʻa, nā lima lima uea kalapona maʻamau, nā paipu kila i hoʻopaʻa ʻia, nā paipu kila i hoʻoheheʻe ʻia no ka lawe ʻana i ka wai haʻahaʻa, ka humuhumu arc welded arc welded paipu no ka lawe ʻana i ka wai kaomi, ka humuhumu kiʻekiʻe kiʻekiʻe o ka welded steel pipes no ka lawe ʻana i ka wai, arc arc. nā paipu kila welded no nā puʻu.
