I mea e maʻalahi ai ka waiho ʻana a me ka lawe ʻana i nā kaula optical, i ka wā e haʻalele ai ke kaula optical i ka hale hana, hiki ke ʻōwili ʻia kēlā me kēia axis no 2-3 mau kilomita. Ke kau nei i ke kaula optical no kahi lōʻihi, pono e hoʻohui i nā kaula optical o nā koʻi like ʻole. I ka hoʻohui ʻana, aia ke kaula optical axis ʻelua i loko o ke kaula uwea. No ka fusion splicing. I kēia manawa, nānā ʻo Hunan GL i nā pono o nā paipu pale uila uila PE no kēlā me kēia:
1. Hoʻokumu ʻia nā waiwai kino maikaʻi me nā mea waiwai polyethylene kiʻekiʻe. ʻAʻole wale ka rigidity maikaʻi, ikaika, akā maikaʻi hoʻi ka maʻalahi, kahi kūpono i ka hoʻokomo ʻana i nā pipelines.
2. ʻO ka pale ʻana i ka corrosion a me ka lōʻihi o ka lawelawe ʻana: Ma nā wahi kahakai, kiʻekiʻe ke kiʻekiʻe o ka wai honua a kiʻekiʻe ka haʻahaʻa o ka lepo. ʻO ka hoʻohana ʻana i ka metala a i ʻole nā paipu ʻē aʻe he anticorrosive. A ʻo ke ola o ka lawelawe he 30 mau makahiki wale nō, a hiki i ka paipu PE ke kū i nā ʻano mea like ʻole, a ʻaʻole pili ʻia e ka lepo lepo.
3. ʻO ka paʻakikī maikaʻi a me ka maʻalahi. ʻO ka paipu PE he ʻano paipu paʻakikī kiʻekiʻe me ka elongation haki ʻoi aku ma mua o 500%. Loaʻa iā ia kahi hiki ke hoʻololi i ka hoʻonohonoho ʻāina ʻole a me ka dislocation o ke kumu. Kūleʻa haʻalulu maikaʻi. Hiki ke wiliwili ʻia nā paipu anawaena liʻiliʻi.
4. He maʻalahi ka pā paipu, he liʻiliʻi ke koena o ka friction, maʻalahi ke ale i ke kaula, a maikaʻi ka manawa hana.
5. ʻO ka hana hoʻokalakupua uila maikaʻi, ke ola lōʻihi o ka lawelawe (nā paipu kanu ʻia e kōkua ma mua o 50 mau makahiki), paʻa, palekana a hilinaʻi i ka hana laina.
6. ʻO ke kaumaha māmā, ka mālamaʻana, ka hoʻokomoʻana a me ke kūkuluʻana, ka mālama kūpono, maʻalahi ka laweʻana a me ka hana.
7. Hiki ke wili ʻia nā paipu anawaena liʻiliʻi, me nā ʻāpana paipu lōʻihi, nā hui liʻiliʻi, a me ka hoʻokomo maʻalahi.
8. Hiki ke hana ʻia ka paipu i nā kala like ʻole e hōʻike i ka ʻokoʻa.
9. ʻOi aku ka maikaʻi o ka hopena haʻahaʻa haʻahaʻa. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o PE he haʻahaʻa loa, a hiki ke hoʻohana pono ʻia i loko o ka pae wela o 20-40. I ke kūkulu ʻana i ka hoʻoilo, ʻaʻole e palupalu ka paipu ma muli o ka hopena maikaʻi o ka mea.
10. Hoʻohālikelike ʻia ka paipu PE me nā paipu metala ʻē aʻe. ʻO ke kūpaʻa ʻaʻahu he 4 mau manawa ma mua o nā paipu metala.
11. Nā ʻano hana hana hou like ʻole. Ma waho aʻe o ke ʻano hana ʻeli kuʻuna, hiki ke kūkulu ʻia nā paipu PE me nā ʻano hana hou ʻole e ʻeli ʻia, e like me ka paipu jacking, liner pipe, a me ka hoʻokaʻawale ʻana i ka paipu. ʻO kēia wale nō kahi i ʻae ʻole ʻia ka ʻeli ʻana. s Koho.
