Hoʻomaka ke kaʻina hana o kahi paipu welded ma nā coils, i ʻoki ʻia e nā lōʻihi i makemake ʻia a hana ʻia i mau papa kila a me nā ʻāpana kila.
ʻO nā ʻāpana kila a me nā ʻāpana kila e ʻōwili ʻia e ka mīkini ʻōwili, a laila hana ʻia i kahi ʻano pōʻai.Ma ke kaʻina hana ERW (Electric Resistance Welded), ua hala ke au uila kiʻekiʻe ma waena o nā kihi, e hui pū ai lākou.Ke hana ʻia ka paipu welded, e hoʻopololei ʻia.
ʻOi aku ka maikaʻi o ka ʻili o ka paipu welded ma mua o ka paipu seamless, no ka mea, ʻo ke kaʻina hana o ka paipu seamless he extrusion.
Ua kapa ʻia ka paipu kila ʻole ma ke ʻano he paipu ʻole.Hiki ke hana ʻia ka paipu kila ʻole (stainless steel cylinder tube) i ke kila kalapona a i ʻole ke kila kila.E lawe i ke kila kalapona no ka laʻana, ua hoʻokuʻu ʻia ka paipu kila ʻole a huki ʻia mai kahi cylindrical paʻa o ke kila, i ʻike ʻia he billet.I ka wā e hoʻomehana ai, ua hou ʻia kahi billet ma waena, e hoʻohuli i ka pahu paʻa i kahi paipu poepoe.
Manaʻo ʻia ka paipu kila ʻole i ʻoi aku ka maikaʻi o nā waiwai mechanical ma mua o ka paipu welded.No ka laʻana, hiki i kahi paipu kila maʻemaʻe ke kū i ke kaomi kiʻekiʻe, no laila ua hoʻohana mau ʻia i ka ʻoihana hydraulic, ʻenekinia a me ke kūkulu ʻana.Eia kekahi, ʻaʻole i loaʻa i kahi paipu kila maʻemaʻe ʻole, no laila ua ʻoi aku ka ikaika o ke kūʻē ʻana i ka corrosion, e hoʻolōʻihi i ke ola o ka paipu kila maʻemaʻe.
