Nā Pōmaikaʻi o ka Hoʻohana ʻana i ka Paipu Polyurethane Lined i nā noi Pipeline Double Submerged Arc Welded (DSAW) EN10219

Ka mua,paipu i hoʻopaʻa ʻia me ka polyurethaneUa kaulana ʻia no kona kūpaʻa maikaʻi loa i ka ʻaʻahu a me ka pala. Hana ka uhi polyurethane ma ke ʻano he pale pale, e pale ana i ka ʻili o loko o ka paipu mai ka pala ʻia e nā mea abrasive e kahe ana ma o ka paipu. He mea nui loa kēia i nā noi paipu DSAW EN10219 no ka mea ua hōʻike pinepine ʻia ka paipu i nā wai wikiwiki kiʻekiʻe a me nā ʻāpana paʻa. Ma ka hoʻohana ʻana i nā paipu i uhi ʻia i ka polyurethane, hiki i nā ʻoihana ke hōʻemi nui i ke alapine o ka mālama ʻana a me nā hoʻoponopono pipiʻi, e hopena ana i ka mālama kālā nui i ka wā lōʻihi.

Eia kekahi, hāʻawi ka paipu i hoʻopaʻa ʻia me ka polyurethane i ka maʻalahi a me ke kūpaʻa i hoʻohālikelike ʻia me nā mea paipu ʻē aʻe. ʻO ke kaʻina hana hoʻoheheʻe arc pālua i hoʻohana ʻia e hana i nā paipu EN10219 e hopena i kahi ʻano paipu maʻemaʻe a me ka ikaika kiʻekiʻe. I hui pū ʻia me nā waiwai maʻalahi a me ka elastic o ka polyurethane, hiki i ka ʻōnaehana paipu hopena ke kū i nā mahana koʻikoʻi a me nā ukana kaumaha, e kūpono ana no nā noi ʻoihana koi. ʻO kēia hui pū ʻana o ka ikaika a me ka maʻalahi ke kumu nui no ke koho mua ʻana o ka paipu i hoʻopaʻa ʻia me ka polyurethane no nā noi paipu DSAW EN10219.

Ma waho aʻe o ko lākou mau waiwai kino, ua mahalo ʻia nā paipu i uhi ʻia i ka polyurethane no ko lākou mau pono kaiapuni. He inert kemika ka uhi polyurethane, ʻo ia hoʻi, ʻaʻole ia e pane me nā mea e lawe ʻia ana ma o nā paipu. ʻAʻole wale kēia e kōkua i ka mālama ʻana i ka maʻemaʻe o nā mea i loko, akā pale pū kekahi i nā mea ʻino mai ka hoʻokuʻu ʻia ʻana i ke kaiapuni. I ka wā e ʻoi aku ka paʻakikī o nā lula kaiapuni, hiki i ka hoʻohana ʻana i nā paipu i uhi ʻia i ka polyurethane ke kōkua i nā ʻoihana e hōʻoia i ka mālama ʻana a hoʻemi i ko lākou kapuaʻi kaiaola.

ʻO ka mea hope loa, ua ʻike ʻia nā paipu i hoʻopaʻa ʻia me ka polyurethane no ko lākou maʻalahi o ke kau ʻana a me ka mālama ʻana. ʻO ke kūkulu ʻana o nā paipu DSAW EN10219 me nā waiwai māmā o ka polyurethane e ʻae ai i ka hoʻokomo wikiwiki a maʻalahi. Eia kekahi, ʻo ka ʻili o loko o ka liner polyurethane e hōʻemi i ka hōʻiliʻili ʻana o ka sediment a hoʻemi i ka friction, e hopena ana i ke kahe ʻoi aku ka maikaʻi a me ka hoʻohana ʻana i ka ikehu haʻahaʻa. ʻO ke ʻano kēia o nā kumukūʻai hana haʻahaʻa a me ka huahana kiʻekiʻe no nā hana ʻoihana e hilinaʻi nei i nā paipu DSAW EN10219.

I ka hōʻuluʻulu manaʻo, ʻo nā pono o ka paipu i hoʻopaʻa ʻia me ka polyurethane e lilo ia i koho maikaʻi loa no nā noi paipu EN10219 i hoʻopaʻa ʻia me ka arc submerged pālua. ʻO ko lākou kūpaʻa i ka ʻaʻahu a me ka pala, ka maʻalahi a me ke kūpaʻa, ka launa pū ʻana me ke kaiapuni, a me ka maʻalahi o ke kau ʻana a me ka mālama ʻana e lilo ia i mea paipu koho no nā ʻano ʻoihana ʻino. Ke hoʻomau nei ka holomua o ka ʻenehana a me ka ulu ʻana o nā kūlana ʻoihana, manaʻo mākou e ʻike i ka hilinaʻi nui ʻana i nā paipu i hoʻopaʻa ʻia me ka polyurethane i nā makahiki e hiki mai ana.
