Hana ʻia ka paipu wiliwili mai ka wili kila. Wehe ʻia ke wili a laila wili ʻia i ka wā e hoʻohuli ʻia ana i ke ʻano o ka paipu. ʻO ka hoʻololi ʻana i ke kihi o ka wiliwili a me ka mānoanoa o ka wiliwili wale nō ka mea e pono ai e hoʻololi mai kahi nui o ka paipu i kekahi. ʻO nā ʻaoʻao ʻelua o ka wiliwili arc pālua i komo i loko o ka mānoanoa piha o ke kila e hōʻoia i ka ikaika o ka paipu i hoʻopau ʻia. Ua hōʻike ʻia nā hoʻokolohua piha piha he ikaika ka paipu wiliwili kiʻekiʻe e like me ka paipu API. ʻO ka ikaika a me ka hana maʻalahi o ka paipu wiliwili e lilo ia i huahana koho no nā ʻano hana like ʻole.

ʻO ka Paipu SSAW (Spiral Submerged Arc-Welding Pipe), i kapa ʻia hoʻi he paipu HSAW (Helical SAW), ke ʻano o ka laina kuʻihao e like me ka helix. Ke hoʻohana nei ia i ka ʻenehana kuʻihao like o Submerged Arc-Welding me ka paipu LSAW. ʻO ke kaʻina hana hana ʻana, ʻo ia ka ʻōwili ʻana i ke kaula kila, i mea e loaʻa ai ke kihi o ke kuhikuhi ʻōwili me ke kuhikuhi o ke kikowaena paipu, e hana ana a me ka kuʻihao, no laila aia ke kuʻihao i loko o kahi laina wili.
