Nā Paipu Welded Spiral no nā Pipeline Gas ma lalo o ka honua EN10219
ʻO kā mākounā paipu wiliwili ʻiaʻo ia ka hopena maikaʻi loa no nā papahana kahi e koʻikoʻi ai ke kūpaʻa ʻana i ka corrosion a me ka kūpaʻa. ʻO ke kaʻina hana wiliwili spiral ʻaʻole wale e hoʻonui i ka ikaika o ka paipu, akā hāʻawi pū kekahi i kahi ʻaoʻao ʻole, e hōʻemi ana i ka hopena o nā leaks a me nā hemahema. ʻO kēia ka mea i kūpono iā lākou no nā kaiapuni koʻikoʻi i ʻike pinepine ʻia i nā noi lalo.
ʻO ka maʻamau EN10219 e hōʻoia i ka hana ʻana o kā mākou paipu me ka pololei a me ka maikaʻi, e hōʻoia ana e hiki iā lākou ke pale i nā pilikia a me nā pilikia o ka lawe ʻana i ke kinoea kūlohelohe. Hoʻopili ʻia i ka paʻa a me ka hilinaʻi, ua hoʻolālā ʻia kā mākou spiral welded pipes e hāʻawi i ka hana lōʻihi, e hōʻemi ana i ka pono no ka mālama pinepine ʻana a me ka hoʻololi.

a. Ua koho ʻia ke ʻano deoxidation penei:FF: Ke kila make loa i loaʻa nā mea hoʻopaʻa naikokene i nā nui e hiki ai ke hoʻopaʻa i ka nitrogen i loaʻa (e laʻa me min. 0,020 % ka huina Al a i ʻole 0,015 % soluble Al). b. ʻAʻole pili ka waiwai kiʻekiʻe no ka nitrogen inā hōʻike ka haku mele ʻana i ka liʻiliʻi o ka huina Al maʻiʻo o 0,020 % me ka palena liʻiliʻi Al/N o 2:1, a i ʻole inā lawa nā mea hoʻopaʻa paʻa N ʻē aʻe.

Ma waho aʻe o kā lākou hana ʻino, ʻoi aku ka maʻalahi a me ka maʻalahi o kēia mau paipu, ʻoi aku ka maikaʻi o ka hoʻonohonoho ʻana a me ke kumu kūʻai. Inā ʻoe e hana nei i kahi papahana paipu hou a hoʻomaikaʻi paha i kahi ʻōnaehana i loaʻa, hāʻawi kā mākou mau paipu welded spiral i ka hui kūpono o ka ikaika, ka maʻalahi, a me ka hoʻokō ʻana i nā kūlana ʻoihana.
E koho i kā mākou mau paipu wiliwili spiral no kāu mau mea e pono ai ka paipu kinoea ma lalo o ka honua a ʻike i ka maluhia o ka noʻonoʻo e hele mai me ka hoʻohana ʻana i nā huahana kūpono.EN10219nā kūlana. E hilinaʻi i kā mākou kūpaʻa i ka maikaʻi a me ka hana e hōʻoia i ka palekana a me ka pono o kāu ʻenehana kinoea.
