Na paipu kila ERWhana ʻia me ka haʻahaʻa haʻahaʻa a i ʻole ke kiʻekiʻe alapine uila "kū'ē".He mau paipu poepoe lakou i wiliia mai na pepa kila me na humu loniu.Hoʻohana ʻia ia e lawe i ke kinoea a me 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.
Ke hoʻokuʻi ʻia nā paipu ERW, hoʻokuʻu ʻia ka wela i ka wā e kahe ana ka manawa ma nā ʻaoʻao pili o ka wahi kuʻi.Hoʻomaʻamaʻa ʻo ia i ʻelua ʻaoʻao o ke kila a hiki i kahi e hiki ai i kekahi ʻaoʻao ke hana i mea paʻa.I kēia hihia, ma lalo o ke kaomi hui, hoʻoheheʻe ʻia nā kihi o ka paipu blank a hoʻokuʻu pū ʻia.
ʻO ka maʻamauNa paipu ERWhe 24 iniha (609 mm), ua hana ʻia nā paipu nui me ka 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.
