ʻO ka nui o nā pipeline kinoea hiki ke loaʻa mai ka 2 -60 iniha ke anawaena akā, no nā paipu aila ka pae mai 4 - 48 iniha ke anawaena o loko e like me ke koi.Paipu ailahiki ke hana ʻia me ke kila a i ʻole ka plastik akā ʻo ka mea i hoʻohana nui ʻia ʻo ka paipu kila.Hoʻohana mau ʻia nā paipu kila wela wela no ka lawe ʻana i ka aila a me ke kinoea.

Nā pōmaikaʻi o nā paipu kila:
ʻO nā paipu kila i kanu ʻia no nā haneli mau makahiki he mau waiwai koʻikoʻi me ke kūpaʻa maikaʻi o ke koʻikoʻi i ke kinoea maoli.He mea haumia lākou a he ʻoi aku ka maikaʻi o ka hopena, ka helu HDB kiʻekiʻe ma 20°C, 60°C a me 80°C, haʻahaʻa haʻahaʻa i ka methane a me ka hydrogen.Loaʻa iā ia ka hana UV hilinaʻi kupaianaha no ka mālama waho.ʻO ka mea insulation maʻamau ka polyurethane foam (PU) he kiʻekiʻe ka wela wela a ikaika ikaika.

ʻO ka paipu aila a me ke kinoea maikaʻi loa:
Loaʻa nā paipu kila liʻiliʻi, waena a nui, akā naʻe, ʻoi aku ka paʻakikī o ka ikaika kiʻekiʻe o ke kila.ʻO ka maʻamau, hoʻohana ʻia ka paipu kila Electric Resistance Welded (ERW) no ka hana ʻaila a me ke kinoea a me nā laina hoʻouna i hoʻopaʻa inoa ʻia e hōʻoiaʻiʻo ana i ka maikaʻi o kāna noi.He maikaʻi nā paipu ERW i nā mea wela a pulu paha e like me ke ala ʻana o ka muliwai a me nā ʻāina ʻino.

ʻO ke koʻikoʻi koʻikoʻi o ka lawe ʻana i ka aila a me ke kinoea a me ka hāʻawi ʻana no ka hāʻawi ʻana i ka ikehu ua hoʻoikaika i ka hana ʻana i nā paipu kila laina a me nā paipu.Hoʻopili ʻia ka corrosion proofing, hoʻohana ʻia ka pena wai ma ka ʻili o ka paipu i waho e pale aku i ka corrosion o ka lewa i ka wā o ka lawe ʻana a me ka mālama ʻana a hiki ke hoʻopili ʻia kahi uhi pale PE 3-layer ma nā paipu ma ke noi a ka Customer.

ʻO nā paipu kila laina nā paipu lōʻihi no nā wai a me nā kinoea.ʻO nā paipu laina laina ʻole i hoʻohana ʻia no ke kūkulu ʻana i nā paipu lōʻihi no nā wai a me nā kinoea hoʻopau ʻia, nā paipu kahua nuklea, nā pipeline ʻōnaehana hoʻomehana, nā paipu kumu nui.No laila, ʻoi aku ka paʻakikī o ka paʻakikī no nā paipu kila laina ma mua o nā pono waiwai tensile.

Hana ʻia nā paipu kila laina a hoʻoheheʻe ʻia i loko o ka umu uila, mālama ʻia me nā slags synthetic a hoʻolei ʻia e nā casters mau.ʻO ke kaʻina hana kila i hoʻohana ʻia e hōʻoia i ka hoʻokō ʻana i ke kila maʻemaʻe kemika me ka pili ʻana i ka sulfur a me ka phosphor i loko o ka hāʻawi ʻana i nā waiwai tensile kiʻekiʻe, ductility a me ka corrosion kūpaʻa o nā paipu e hoʻohana ʻia ma nā haʻahaʻa haʻahaʻa i loko o nā ʻano media corrosion.

He mea koʻikoʻi loa nā paipu kila wela wela no ka ʻoihana ʻaila a me ka ʻea.ʻO nā paipu kila, i kanu ʻia no nā haneli mau makahiki, loaʻa nā waiwai kupaianaha e pili ana i ka pale ʻana i ke koʻikoʻi maikaʻi loa i ke kinoea maoli a me kona mau mea haumia, haʻahaʻa haʻahaʻa i ka methane a me ka hydrogen, ka helu HDB kiʻekiʻe ma 20 ° C, 60 ° C a me 80 ° C, ʻoi aku ka maikaʻi. ka hopena o ka hopena, ʻokiʻoki, a me ka hana UV hilinaʻi no ka mālama ʻana i waho.ʻO ka mea insulation maʻamau ka polyurethane foam (PU), he kiʻekiʻe ka wela wela a ikaika ikaika.

Loaʻa nā paipu liʻiliʻi, waena a nui a ʻoi aku ka paʻakikī o ka ikaika kiʻekiʻe o ke kila.ʻO ka maʻamau, hoʻohana ʻia ka Electric Resistance Welded (ERW) steel Pipe no ka hoʻoili ʻana i ka aila a me ke kinoea a me nā laina hoʻouna i hoʻopaʻa inoa ʻia a hōʻoia i ka maikaʻi o kāna noi.He maikaʻi like kēia mau paipu aila a me ka ʻea ma nā wahi wela a pulu paha e like me ke ala o ka muliwai a me ka ʻāina ʻino.ʻO ka hoʻohana ʻana i ke kila ka mea maʻamau no ka paipu kūpono no ka hoʻohana ʻana i ka lawe ʻana i ke kinoea, ka wai a me ka ʻaila i loko o nā ʻoihana ʻaila a me nā ʻoihana kūlohelohe.
