Hana ʻia ka paipu huikau polyethylene i hoʻopaʻa ʻia me ke kila ʻōwili anuanu a me nā thermoplastics ma ke ʻano he mea maka, a ʻo nā paipu kila lahilahi ʻeleʻele i hana ʻia e ka argon arc butt welding a i ʻole plasma spiral welding e hoʻohana ʻia i mea hoʻoikaika. ʻO ka ʻaoʻao o waho a me loko he thermoplastics composite ʻelua ʻaoʻao. ʻO kahi ʻano hou o ka paipu puʻupuʻu composite, No ka mea ua hoʻopaʻa ʻia ka paipu porous i hoʻopaʻa ʻia i ka thermoplastic mau, ʻaʻole i lanakila wale kēia paipu hui i nā hemahema o nā paipu kila a me nā paipu plastik, akā loaʻa nō hoʻi ka rigidity o nā paipu kila a me ka corrosion. kū'ē o nā paipu plastik. He hopena ia no nā ʻoihana ʻaila a me nā kemika. He pipeline koi nui ia o nā paipu paʻa nui a me ke anawaena ma nā kahua o ka lāʻau lapaʻau, ka meaʻai, ka mining, ke kinoea a me nā māla ʻē aʻe. He mea hoʻokō ʻenehana hoʻololi hoʻi ia e hoʻoponopono i ka pipeline nui o ke kūkulu ʻana a me ka lako wai kūloko. He ʻano hou ia o ka pipeline composite i ka 21stkenekulia.
Nā hiʻohiʻona
Ka ikaika kiʻekiʻe a me ka hoʻonui laina haʻahaʻa.
Ma muli o ka hoʻoikaika ʻia ʻana o ke kiʻi kila, ʻoi aku ka ikaika o ka pipe plastic composite pipe perforated steel, rigidity kiʻekiʻe a me ka hopena hopena ma mua o ka paipu plastik. I ka manawa like, ʻo ka hopena kaohi o ke kiʻi kila e hana ai i ka paipu hoʻohui ʻia i loko o ke kila kila he laina haʻahaʻa e like me ka paipu kila. ʻO ka helu hoʻonui a me ke kū'ē kū'ē.
ʻO ke kūʻē ʻana a me ka ʻaʻahu.
ʻO ka mea polyethylene kiʻekiʻe kiʻekiʻe i koho ʻia no ke kila perforated pipe plastic composite pipe he crystalline non-polar polymer material me nā waiwai kemika paʻa, kūpaʻa i ka hapa nui o ka waikawa, nā paʻakai alkali a me nā media organik, a me ka corrosion electrochemical. ʻO ka hana wili he 5 mau manawa kiʻekiʻe ma mua o nā paipu kila.
Nā ʻāpana ʻenehana
Ke hoʻohana nei kēia huahana i ka resin polyethylene kūikawā, a me kāna mau waiwai kino a me ka mechanical e hālāwai me ka Ministry of construction standard CJ/T181-2003 a me ka maʻamau ʻoihana kemika HG/T3706-2014.
