Hana ʻia ka paipu kila ERW me ka haʻahaʻa haʻahaʻa a i ʻole ke alapine kiʻekiʻe "kū'ē". He mau paipu poepoe ia i wiliia mai na pepa kila me na humu loniu. Hoʻohana ʻia ia no ka lawe ʻana i nā mea wai e like me ka aila a me ke kinoea maoli, a hiki ke hoʻokō i nā koi like ʻole o ke kaomi kiʻekiʻe a me ka haʻahaʻa. Aia i kēia manawa kahi kūlana koʻikoʻi ma ke kahua o nā pipeline transport ma ka honua.
I ka wā e wili ai i nā paipu ERW, hoʻokumu ʻia ka wela i ka wā e kahe ai ke au uila ma nā ʻili pili o ka wahi welded. Hoʻomaʻamaʻa ia i nā ʻaoʻao ʻelua o ke kila a hiki i kahi e hiki ai ke hoʻohui i kekahi ʻaoʻao. I kēia hihia, ma lalo o ke kaomi hui ʻana, hoʻoheheʻe ʻia nā ʻaoʻao o ka paipu blank.
ʻO ka maʻamau o nā paipu ERW he 24 iniha ke anawaena o waho (609 mm), hana ʻia nā nui nui ma SAW.
Nui nā paipu i hiki ke hana ʻia me ke ʻano ERW. Ma lalo mākou e papa inoa i nā kūlana maʻamau i ka paipu.
