Paipu olohelohe :
Manaʻo ʻia kahi paipu inā ʻaʻole i hoʻopili ʻia kahi paipu. ʻO ka mea maʻamau, i ka pau ʻana o ka ʻōwili ʻia ʻana ma ka wili kila, e hoʻouna ʻia ka mea hū ʻole i kahi i hoʻolālā ʻia e pale a ʻaʻahu paha i ka mea me ka uhi i makemake ʻia (e hoʻoholo ʻia e nā kūlana honua o kahi e hoʻohana ʻia ai ka mea). ʻO ka paipu palaka ka ʻano paipu maʻamau i hoʻohana ʻia i ka ʻoihana piling a hoʻokomo pinepine ʻia i loko o ka lepo no ka hoʻohana ʻana. ʻOiai ʻaʻohe haʻawina paʻa e hōʻike ʻia ʻoi aku ka paʻa o ka paipu ʻole ma mua o ka paipu i uhi ʻia no nā noi piling, ʻo ka paipu ʻole ka mea maʻamau no ka ʻoihana hana.
Paipu Galvanizing :
ʻO ka Galvanizing a i ʻole ka galvanization kekahi o nā ʻano mea kaulana loa o ka uhi paipu kila. ʻOiai ʻo ka metala ponoʻī he nui nā waiwai maikaʻi loa i ka wā e pili ana i ka pale ʻana i ka corrosion a me ka ikaika tensile, pono e uhi hou ʻia me ka zinc no ka hoʻopau maikaʻi ʻana. Hiki ke hana ʻia ka Galvanizing ma nā ʻano he nui, ma muli o ka loaʻa o ke ʻano. ʻO ka ʻenehana kaulana loa, ʻo ia ka hoʻoheheʻe wela a i ʻole ka batch dip galvanizing kahi e hoʻokomo ai i kahi paipu kila i loko o ka ʻauʻau o ka zinc hehee. ʻO ka hopena metallurgical i hoʻokumu ʻia e ka paipu kila a me ka zinc e hoʻopau i ka ʻili o ka metala e hāʻawi ana i kahi ʻano kūpaʻa ʻole ʻaʻole i loaʻa ma ka paipu ma mua. ʻO kekahi pōmaikaʻi ʻē aʻe o ka galvanizing ʻo ia ka uku kumukūʻai. Ma muli o ka maʻalahi o ke kaʻina hana a ʻaʻole koi i ka nui o nā hana kiʻekiʻe a me ka hoʻoponopono ʻana, ʻo ia ka mea i koho ʻia no nā mea hana a me nā ʻoihana.
FBE - ʻO Fusion Bonded Epoxy Powder Coating Paipu :
Hāʻawi kēia uhi paipu i ka pale maikaʻi loa no nā pipeline liʻiliʻi a nui me nā mahana hana haʻahaʻa (-30C a 100C). Hoʻohana pinepine ʻia kāna noi no ka ʻaila, kinoea, a i ʻole nā paipu wai. ʻO ka adhesion maikaʻi loa e hiki ai ke pale i ka corrosion lōʻihi a me ka pale o ka pipeline. Hiki ke hoʻohana ʻia ka FBE ma ke ʻano he papa ʻelua e hāʻawi ana i nā waiwai kino ikaika e hōʻemi i ka pōʻino i ka wā o ka lawelawe ʻana, ka lawe ʻana, ka hoʻonohonoho ʻana, a me ka hana.

3PE Epoxy Coating Paipu :
ʻO 3PE Epoxy i uhi ʻia i ka paipu kila me 3 mau ʻāpana, ka uhi FBE mua, ʻo ka waena ka papa hoʻopili, ma waho o ka papa polyethylene. ʻO ka 3PE coating pipe kekahi huahana hou i hoʻomohala ʻia ma ka FBE coating kumu mai ka makahiki 1980, aia nā mea hoʻopili a me nā papa PE(polyethylene). Hiki i ka 3PE ke hoʻoikaika i nā waiwai mechanical o ka pipeline, ke kūpaʻa uila kiʻekiʻe, wai ʻole, hiki ke hoʻohana, anti-aging.
No ka mea ʻO nā papa mua he epoxy i hoʻopaʻa ʻia, ʻoi aku ka mānoanoa ma mua o 100μm. (FBE＞100μm）)
ʻO ka papa ʻelua he adhesive, ʻo ia ka hopena e hoʻopaʻa i ka epoxy a me ka papa PE. (AD: 170~250μm)
ʻO ke kolu o nā papa he mau ʻāpana PE ka polyethylene i nā mea maikaʻi i ka anti-wai, ke kūpaʻa uila a me ka pōʻino anti mechanical. (φ300-φ1020mm)
No laila, ua hoʻohui pū ʻia ka paipu uhi 3PE me nā pono o FBE a me ka PE. ʻOi aku ka nui a hoʻohana nui ʻia i ka lawe ʻana o ka pipeline i ka wai, ke kinoea a me ka aila.
