FAQ
Q1. He aha nā pōmaikaʻi nui o ka hoʻohana ʻana i ka paipu kila carbon welded spiral?
- Loaʻa nā pōmaikaʻi koʻikoʻi i ka ikaika kiʻekiʻe, ka pale ʻana i ka corrosion maikaʻi, ke kūpaʻa kiʻekiʻe o ke kaomi, a me ke kūpono no nā noi kinoea maoli.
Q2. Pehea e pili ai ke kaʻina hana i ka maikaʻi?
- ʻO kā mākou ʻenehana hana holomua e hōʻoia i ka hana ʻana o kēlā me kēia paipu me ka pololei, ka hopena i kahi huahana hilinaʻi a paʻa.
Q3. Ua kūpono anei ka paipu no nā hoʻohana ʻē aʻe?
- ʻAe, ʻoiai he kūpono ia no nā pipeline kinoea, hiki ke hoʻohana ʻia i nā lako wai, nā ʻōnaehana wai, a me nā mea ʻoihana ʻē aʻe.
Q4. He aha ke ola i manaʻo ʻia o ka pipeline?
- Me ka hoʻonohonoho pono ʻana a me ka mālama ʻana, hiki i kā mākou spiral welded carbon steel pipes ke hoʻomau no nā makahiki he mau makahiki, e hāʻawi ana i ka waiwai lōʻihi.
