Ma kahi o ka carbon, kā mākou spiral seam tubes e like me nā mea nui e like me nickel a me ka chromium. ʻO Nickel kahi mea i ka metala ferromagnetic e hoʻohui i ka ikaika holoʻokoʻa a me ka pasashalilis o ka paipa. Hoʻohuiʻia, e kū pono ana i ka corrosion a e hōʻoia i ke olaʻoi aku ka lōʻihi o kā mākou mau piptes. Chromium, ma kekahiʻaoʻao, he mea koʻikoʻi ia ma keʻano he mea kila maikaʻiʻole a loaʻa i ka paleʻana o ka corrosion. ʻO ka hoʻopiliʻana o ka chromium i loko o kā mākou pila spiral seam e hoʻonui hou i kā lākou longon a me ka hilinaʻi.
ʻO kekahi o nā mea waiwai nui o kā mākou pipes spiral seam i ko lākou hoʻolālāʻana,ʻo ia ka mea i loaʻa ma o kaʻenehana maʻamau. ʻO kā mākou moku'āina-o-ka-art-artero (submered arc spiral cir chiral) kaʻenehana welding e hōʻoia i kahi paʻa nui a lōʻihi loa ʻAʻole e hoʻonui waleʻia kēiaʻenehana Welding i nā mea hana mechanical o ka paipa, akā e hōʻoiaʻiʻo pū kekahi i kahi ākea o nā wahi kūponoʻole o nāʻano likeʻole a iʻole nā mea pāʻani.
Hoʻohana nuiʻia ko mākou mau Pipsi spiral i nāʻoihana lehulehu, me ka aila a me nā aila, ke kūkuluʻana i nā wai. Hiki ke hoʻokōʻia ma Onshore a me nā hana o nā hana a me nā'ōnaehana pipeline no nā kumu likeʻole. Me kona paleʻana o ka corrosion maikaʻi loa a me ke kiʻekiʻe kiʻekiʻe kiʻekiʻe,ʻo kā mākou koho ke koho mua no ka paila i nā wahi o nā wahiʻeha.
