Me ka emi ʻana o ka ikehu a me nā kumu waiwai, lawe ka ʻauwaʻa pipeline i ke kinoea, asphalt a me nā huahana ʻaila haʻahaʻa haʻahaʻa, a ke ulu mau nei ke kūkulu ʻana i nā paipu moana. Ua hoʻopau ʻia ka hoʻomohala ʻana. ʻO kēia ka hoʻolauna ʻana i kekahi mau ʻenehana.
Kūleʻa wela kiʻekiʻe 3pe anticorrosion
Ka mālama ʻana i ka ʻili o ka ʻili kiʻekiʻe 2.5 kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe, peʻa 60 microns. Ma hope o ka puhi ʻana a me ka wehe ʻana i ka ʻōpala, hoʻomaʻemaʻe ʻia ka ʻili o ka paipu kila me ka phosphoric acid a me ka chromate e wehe i ka lepo i hoʻopili ʻia ma ka ʻili o ka paipu kila.
Hoʻohana ka papa mua i ka pauka epoxy anti-corrosion FBE e hoʻololi i ka pauka anti-corrosion 3pe maʻamau, e hoʻomaikaʻi i ka hana kemika o ka honua a hoʻonui i ka pili me FBE. ʻO ka mahana hoʻololi aniani o FBE aia ma waena o 100-150 ° C, a ʻo ka Vicat softening o ka adhesive ʻO ka wahi palupalu o HDPE he 124 ° C ma muli o kona hāʻawi haʻahaʻa molecular kaumaha, ʻoi aku ka paʻakikī o nā waiwai a me ke kū'ē ikaika i ka pōʻino mechanical.
ʻO ka papaʻelua ka mea nui loa. ʻO ka hana wela kiʻekiʻe o 3pe e pili ana i nā waiwai o nā mea maka. I kēia manawa, hoʻokumu ʻia nā mea waiwai kiʻekiʻe e Xinlong Anticorrosion i nā hopena i huki ʻia mai ka hana noiʻi ʻoihana. Hoʻemi ʻia ka mahana palupalu o ka mea hoʻopili e 20 °C, loaʻa ka mahana hana kiʻekiʻe loa o ka 3pe anti-corrosion layer i hoʻololi ʻia.
