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 perforated plastic composite pipe 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.
