Paipu kila welohoʻohana nui ʻia i nā ʻāpana hana o nā kaʻa, nā kaʻa kaʻa, nā tractors, nā kaʻa a me nā kaʻa kaʻa nui. Loaʻa i ka paipu ka coefficient forging nui, ke kulou ikaika a me ke kūpaʻa torsion, ka ʻili laulima a me ke kaumaha māmā. Hoʻohana ʻia nā paipu ʻāpana ʻāpana like ʻole e hana i nā pou ʻohi ma nā trolleybuses, no ka mea, ʻo kēia kiʻekiʻe kiʻekiʻe-ikaika welded kila paipu i ka ikaika a me ka elasticity.
Hoʻohana nui ʻia nā paipu kila welded i nā mea kani, nā lako kelepona a me nā mea lapaʻau e hana i nā brackets, alakaʻi alakaʻi, a me nā papa o nā pahu a me nā keʻena, i loaʻa iā lākou nā hiʻohiʻona o ke kaumaha māmā, nā hiʻohiʻona nani, ke ʻano moʻolelo, a me ka maʻalahi a me ka lawe ʻana. Hoʻohana pololei ʻia nā hana ʻokiʻoki i ka nila plum-blossom needle kiʻekiʻe ikaika welded paipu kila ma ke ʻano he mea hoʻonohonoho iwi. ʻO ke alakaʻi nalu no ke kamaʻilio lekiō UHF ua hana pū ʻia me ka paipu kila welded ikaika kiʻekiʻe me nā ana kikoʻī.

Ma nā ʻano mea wela like ʻole, nā lako mīkini a i ʻole nā ​​​​lekiō a i ʻole nā ​​​​mea hoʻouna, hoʻohana nui ʻia nā paipu kila welded ikaika me nā lau a me nā iwi ʻaoʻao e hana i nā radiators a i ʻole nā ​​​​mea hoʻololi wela. Hiki i ka hopena ke hoʻemi pono i ka mahana o nā mea hana a i ʻole nā ​​​​mea hana, i hiki ke mālama i ka hana maʻamau no ka manawa lōʻihi. Hoʻohana ʻia nā paipu kila welded kiʻekiʻe e like me nā paipu hoʻoheheʻe wela no nā mea hoʻololi wela, he hopena maikaʻi ka hoʻololi ʻana i ka wela a hiki ke hoʻihoʻi hou i ka nui o ka wela wela, hoʻomaikaʻi i ka hana wela, a mālama i ka ikehu.

I ka hana ʻana i nā mea haʻuki a me nā mea hana, hoʻohana mau ʻia nā paipu kila welded kiʻekiʻe e pani i nā huahana lāʻau waiwai. He maʻalahi ke ʻano hana o kēia mau mea hana, maʻalahi ka hana, maikaʻi ka maikaʻi, a paʻa lākou.
I ka hana ʻana i nā mea hana, hoʻohana mau ʻia nā bellows welded steel pipe bellows no ka hana ʻana i nā mea hōʻike haʻalulu ma nā mīkini like ʻole a me nā rockets e hōʻemi i ka haʻalulu, hoʻemi i ka walaʻau, a hōʻoia i ka hana maʻamau o nā mea hana. E like me nā hiʻohiʻona o ka pauku, hiki ke hoʻokaʻawale ʻia nā paipu kila welded i ʻekolu mau ʻāpana: nā paipu kila i hoʻopaʻa ʻia i ka paia, nā paipu kila welded ʻokoʻa a me nā paipu ʻāpana ʻokoʻa.
