Me ka hoʻomohala ʻana o ka ʻoihana pipeline, ua kākau inoa ʻia nā mea hou i ka mākeke. Ma ke ʻano he huahana maikaʻi i ka ʻoihana insulation thermal, ʻo ka polyurethane direct-buried thermal insulation paipu i loaʻa nā hiʻohiʻona insulation thermal maikaʻi loa a me ka maikaʻi o ka hana. Hoʻohana nui ʻia e ka poʻe a ua ʻike pū ʻia e nā mea hoʻohana. He aha ke ʻano o ka polyurethane thermal insulation paipu i hoʻohana ʻia ma ke ʻano he paipu kanu pololei? Pono e hana i kahi hana maikaʻi o ka palekana i ka wā o ke kūkulu ʻana, a he mea nui hoʻi ka mālama ʻana i ka wā kūkulu. Ma lalo, he polyurethane au i kanu pono ʻia i ka paipu hoʻoheheʻe wela.

I ka hoʻomaka ʻana i ke kūkulu ʻana i ka paipu insulation i kanu ʻia i ka polyurethane pololei, pono e nānā mua ʻia ka palahalaha o ke awāwa a me ka maloʻo o ka lalo o ke awāwa, a ʻo 200mm mānoanoa ke one maikaʻi e hāʻawi ʻia ma ke ʻano he cushion i ka manawa like, a me ka Pono e hoʻohana ʻia nā ʻaoʻao ʻelua o ka polyurethane direct-buried insulation pipe. Ua uhi ʻia i ke one maikaʻi. ʻO kēia no ka maʻalahi o ke kūkulu ʻana a me ka palekana o nā paipu insulation polyurethane.

Ma hope o ka hoʻokomo ʻia ʻana o ka paipu insulation polyurethane, pono e hoʻokō ʻia ka hoʻāʻo ʻana o ka wai. Ma hope o ka hala ʻana i ka hoʻāʻo ʻana i ke kaomi wai, hiki ke hoʻokō ʻia ka hoʻomaʻamaʻa foaming interface. I ka manawa o ka hoʻomaʻamaʻa ʻana i ka puaʻa, pono e hōʻoia ʻia ka hoʻomaʻemaʻe waha o ka paipu kila. ʻO kēia ke hāpai i ke kiʻekiʻe. ʻO ka palekana o nā paipu insulation polyurethane.

Ma hope aku, i ka wā e komo ai ka paipu insulation polyurethane i loko o ka hale a i ʻole ka auwaha, pono e hoʻohui ʻia ma o ka pā pā e hōʻoia i ka palekana o ka pipeline. ʻOiaʻiʻo, ua maʻalahi ka hoʻokomo ʻana i ka paipu insulation polyurethane, akā ʻo kekahi mau mea mālama i ke kī e hoʻomaikaʻi ai i ka palekana o ka pipeline, no laila pono ʻoe e hoʻolohe i kēia ʻano hana i ka wā e hoʻokomo ai i ka paipu insulation polyurethane.
