I nā makahiki he 20 i hala iho nei, ua hoʻohana nui ʻia nā paipu plastik hou i nā kahua hoʻokomo wai o ke kūlanakauhale, ke kinoea a me ka mana. ʻOi aku me ka hoʻomau mau ʻana a me ka hana hou o ka ʻenehana polyethylene polymerization, ʻoi aku ka nui o nā mea polyethylene ikaika tensile. No ka hoʻomāhuahua ʻana i ka nui o nā pae paʻi no nā paipu plastik, ʻoi aku hoʻi i nā makahiki i hala iho nei, ma o ka noiʻi ʻana o ka ʻenehana interdisciplinary, ua hoʻopau maikaʻi ka ʻenehana hui kila-plastic i hoʻokomo ʻia i nā pilikia o nā paipu polyethylene (PE) e pili ana i ka pae paʻi, anti- corrosion, a me ke anawaena kaapuni pono. Hoʻohana ʻia ma kahi ākea ākea o nā noi lawe wai.

Hoʻolālā: ʻO kēia huahana he kiʻi i hoʻoikaika ʻia me kahi papa kumu o ka ʻeha mau ʻana i ka uea kila ikaika ma hope o ka mālama ʻana i ka uhi ʻana, a ua hui pū ʻia kahi kāmela wela wela a me ka plastic i loko o kahi paipu holoʻokoʻa e ke ʻano hoʻoheheʻe extrusion.

Hana waiwai o ka paipu
Ke hoʻohana nei i ka polyethylene kiʻekiʻe e like me nā mea ʻāpana o loko a me waho, ʻo ka mesh skeleton polyethylene plastic composite pipe ka hana maikaʻi loa o nā huahana polyethylene pipe. Ma muli o ka hopena o ka iwi kila, ʻoi aku ka liʻiliʻi o ka mānoanoa o ka pā ma mua o nā paipu plastik maʻemaʻe. ʻOi aku ka nui o ka circulation агеа, a ʻo ka pale ʻana i ka corrosion maikaʻi a me ke kūpaʻa ʻana e hōʻoia i ke ola lawelawe o ka paipu e like me 50 mau makahiki, kahi e hoʻomaikaʻi maikaʻi ai i ka hana hoʻokele waiwai o ka pipeline.
