Me ka ulu wikiwiki o ka hoʻokele waiwai, ke holomua nei ka nohona.Ma nā kula he nui e like me ka mahiʻai ʻoihana a me ka mining, ka hoʻokuʻu ʻana i ka wai ʻino a me ka wai i loko o ka ʻōnaehana pipeline nui o nā pipelines municipal, he aha ke ʻano o nā paipu e hoʻohana ai a me nā mea e hoʻohana ai i ʻaelike ʻia e nā keʻena noiʻi nui ma Kina.ʻO nā paipu HDPE, me kā lākou hana ʻoi aku ka maikaʻi, ua hoʻololi mālie i nā paipu sima mua a me nā paipu hao.ʻO kēia mau paipu kahiko me nā mea hoʻoheheʻe ʻia ua nalowale mālie mai ka mākeke me ka holomua o ka modornization.He lōʻihi ke ola o nā paipu HDPE, ka maʻemaʻe maikaʻi, ʻaʻole i pālākiō, ʻaʻole i hoʻopaʻa i ka bacteria, kūpaʻa i nā kemika like ʻole, loaʻa i ka paia i loko maʻemaʻe, ke kūpaʻa maikaʻi o ka ʻaʻahu, ke kūpaʻa hopena, ka ikaika kiʻekiʻe a maʻalahi ke lawe a hoʻokomo.
Loaʻa nā paipu HDPE i nā papa he 18 me nā calibers mai DN16 a i DN315.E hooheheeia na paipu HDPE ma kahi mahana o 190°C-240°C.Ma ka hoʻohana ʻana i kēia hiʻohiʻona, e hoʻopili piha ʻia ka ʻāpana heheʻe o ka paipu (a i ʻole nā pili paipu) a mālama ʻia ma lalo o ke kaomi kūpono, a hiki ke hoʻopili paʻa ʻia nā mea ʻelua ma hope o ka hoʻoluʻu ʻana.E like me ka nui o ka paipu, hiki ke hoʻokaʻawale ʻia i kēia mau mea: i ka wā DN≤63, hoʻohana ʻo ia i ka hoʻohui ʻana i hoʻoheheʻe ʻia me ka hoʻoheheʻe wela wela;i ka DN≥75, hoʻohana ʻo ia i ka pilina hoʻoheheʻe wela a i ʻole ka hoʻoheheʻe ʻana i ke kumu hoʻoheheʻe uila;ke hoʻohui ʻia me nā mea like ʻole, hoʻohana ʻo ia i ka pili flange a i ʻole silk buckle.
Hoʻohana nui ʻia nā paipu HDPE no: ʻōnaehana wai ʻenehana kūloko, ʻōnaehana wai i loko no nā hale, ʻōnaehana wai kanu waho a me nā ʻōnaehana wai kanu no nā kaiāulu a me nā hale hana, hoʻoponopono pipeline kahiko, ʻōnaehana wai hoʻomaʻamaʻa ʻenehana pipeline, nā paipu wai ʻoihana no ka mahiʻai, ka irrigation a me nā māla ʻē aʻe, a me nā mea ʻē aʻe. Eia naʻe, pono e hoʻomaopopo ʻia ʻaʻole hiki ke hoʻohana ʻia nā paipu HDPE no nā paipu wai wela.
Hoʻohana nui ʻia ka pipeline wai HDPE, no ka mea, loaʻa iā ia nā pōmaikaʻi ʻaʻole hiki ke hoʻohālikelike ʻia nā pipeline ʻē aʻe: 1, maʻalahi i ka wili a me ka welding electrofusion a hana i kahi ʻōnaehana impermeable paʻa.Ke waiho ʻia ma ka ʻauwaha, hiki iā ia ke hōʻemi i ka nui o ka ʻeli ʻana o ka ʻauwaha a hoʻemi i ka nui o nā mea pono.2, māmā kaumaha a maʻalahi e hoʻouka a mālama;3, ʻaʻahu ikaika a me nā waiwai hydraulic maikaʻi loa, i loko o ka pipeline i kanu ʻia hiki ke ʻole me ka ʻole o ka pale o waho.Hiki ke hoʻohana ʻia i ka ʻōlaʻi a me ka ʻeli ʻana i nā wahi noho ʻāina, a hiki ke waiho ʻia ma lalo o nā kahawai ma ke ʻano o ke kahe ʻana.He kūpono no ka lawe ʻana i nā mea waikawa a me ka alkaline, ka lawe ʻana i ka wai, ke kinoea maoli, ke kinoea a me nā mea ʻē aʻe;5. Hiki ke hoʻololi i ke kaiapuni maikaʻi a me ka pale hau.Hiki ke hoʻohana ʻia no nā paipu wai i loko a me waho.6. ʻO ke ola lawelawe lōʻihi, me ke ola o ka lawelawe ma kahi o 50 mau makahiki.7. Maʻalahi e hana hou a hoʻohana.
