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.
E hoʻoikaika i ka iwi iwi e hoʻopau pono i nā māwae
ʻO ka hoʻohana ʻana i kahi ʻāpana koʻikoʻi kiʻekiʻe e like me ka hoʻoikaika ʻana i ka iwi i ka hana ʻana i ka hana maʻamau a me ka hoʻolaha wikiwiki ʻana o nā mea polyethylene, a ʻoi aku ka ikaika compressive kiʻekiʻe (ʻo ke kaomi nominal o ka pipeline wai hiki i З.5МРа) a me ka malihini сгеер. ke kū'ē, Ke kū'ē i ka hopena ki'eki'e, a me kāna mau hō'ailona hana e like me nā paipu polyethylene ki'eki'e.
