ʻO Spiral submerged arc welded steel pipe i kekahi manawa e hālāwai me kekahi mau kūlana i ke kaʻina hana, e like me nā lua ea.Ke loaʻa nā lua ea i ka seam welding, e hoʻopilikia ia i ka maikaʻi o ka pipeline, e hoʻokuʻu i ka pipeline a lilo i nā poho kaumaha.Ke hoʻohana ʻia ka paipu kila, ʻo ia hoʻi ke kumu o ka corrosion ma muli o ka noho ʻana o nā lua ea a pōkole ka manawa lawelawe o ka paipu.ʻO ke kumu maʻamau o nā lua ea i loko o ke kaʻina hoʻoheheʻe ʻana i ka paipu kila, ʻo ia ka hele ʻana o ka kahe wai a i ʻole kekahi lepo i loko o ke kaʻina hana kuʻi, e hoʻoulu ai i nā lua ea.No ka pale ʻana i kēia, pono e koho i ka haku mele like ʻole i ʻole nā pores i ka wā wili.
I ka wā e wili ai, ʻo ka mānoanoa o ka hōʻiliʻili solder ma waena o 25 a me 45. I mea e pale ai i nā lua ea ma ka ʻili o ka paipu kila spiral, e mālama ʻia ka ʻili o ka pā kila.I ka wā wili, e hoʻomaʻemaʻe mua ʻia nā lepo o ka pā kila i mea e pale aku ai i nā mea ʻē aʻe mai ke komo ʻana i ka wili wili a hana i nā lua ea i ka wā wili.
