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.

ʻOʻoleʻa apo kiʻekiʻe a me ka rigidity kiʻekiʻe
ʻO ka paipu hoʻoheheʻe i hoʻohuihui ʻia i ke kila kila, ʻo ia ka ʻoʻoleʻa apo kiʻekiʻe a me ka rigidity kiʻekiʻe kokoke i nā paipu metala, a kūpono loa no ka hoʻomoe ʻana i nā alapiʻi paipu.
Hana palekana
ʻO ke kiʻi i hoʻoikaika ʻia o ke kāʻei kila i hoʻopaʻa ʻia i ka paipu a me nā mea palaka i hoʻopaʻa ʻia i loko o ka ʻupena ʻupena, a aia kahi hopohopo no ka ʻili ʻana i ka pā i loko a me waho a me ke kila kila. He kūpaʻa ikaika ka pilina fusion uila i ke kaha kiʻi axial, a he hilinaʻi kiʻekiʻe ka ʻōnaehana pipeline. Ma lalo o nā kūlana maʻamau, hiki i ke ola lawelawe ke hiki i 50 mau makahiki.
