ʻO ka hoʻokomo ʻana i nā paipu kila welded spiral ua hoʻomaikaʻi nui i nā kaʻina hana wili paipu, maʻalahi i ke kaʻina hana a hōʻemi i ka manawa o ka papahana holoʻokoʻa.ʻO ka hoʻonohonoho maʻalahi, i hui pū ʻia me ka lākiō kiʻekiʻe o ka ikaika-a-kaumaha, hiki ke hana i kahi kaʻina hana maʻalahi a maikaʻi.ʻO kēia ke ʻano o ka mālama nui ʻana i nā koina hana, nā pono lako a me nā lilo hoʻokele papahana, ʻoiai e hōʻoia ana i ka maikaʻi a me ka lōʻihi.

I ka hopena:

Ma ka hōʻuluʻulu manaʻo, ua hoʻololi hou ka paipu wiliwili spiral i ke kahua o nā kaʻina hana wili paipu, ʻoi aku hoʻi i ka ʻoihana aila a me ke kinoea.ʻO kona hoʻohui pū ʻana o ka ikaika, ka lōʻihi, ka versatility a me ka maikaʻi o ke kumu kūʻai i mea kūpono no nā ʻoihana ikehu e ʻimi nei i nā hopena hilinaʻi.Me ke koʻikoʻi o ke kaomi, ka ʻino a me ka leakage, ʻoi aku nā paipu kila welded spiral ma mua o nā ʻōnaehana pipeline kuʻuna e hāʻawi i kahi pūnaewele hoʻomau a palekana no ka lawe ʻana i nā kumuwaiwai koʻikoʻi.Ke hoʻomau nei ka ʻoihana kūkulu i ka holomua ʻenehana, ua lilo ka paipu spiral welded i mea hōʻike i ke akamai kanaka a me ka hana hou, e hōʻike ana i ka wā e hiki mai ana o ka pono, palekana a me ka hilinaʻi.
