Paipu kila i uhi ʻiahana ʻia e ka uhi ʻana i ka plastic ma muli o ka paipu wiliwili spiral nui a me ka paipu welded kiʻekiʻe. ʻO ke anawaena paipu kiʻekiʻe he 1200mm. Hiki ke uhi ʻia ka polyvinyl chloride (PVC), polyethylene (PE), epoxy ma muli o nā pono like ʻole. ʻO Resin (EPOZY) a me nā mea hoʻonaninani ʻē aʻe me nā waiwai like ʻole, ka hoʻopili maikaʻi ʻana, ka pale ʻana i ka corrosion ikaika, ke kūpaʻa ʻana i nā waikawa ikaika, ka alkali ikaika a me nā mea ʻino ʻē aʻe, non-toxic, non-corrosive. ke kū'ēʻana i ke komoʻana, He maʻalahi kaʻili o ka pipeline aʻaʻole pili i kekahi mea, hiki ke hoʻemi i ke kū'ēʻana i ka wā o ka laweʻana, hoʻonui i ka holo kahe a me ka maikaʻi o ka laweʻana, a ho'ēmi i ke kaumaha o ka laweʻana. ʻAʻohe mea hoʻoheheʻe a ʻaʻohe mea exudate i loko o ka uhi, no laila ʻaʻole ia e hoʻohaumia i ka mea i lawe ʻia, e hōʻoia i ka maʻemaʻe a me ka hoʻomaʻemaʻe o ka wai. Hiki ke hoʻohana like ʻia me ke anuanu a me ka wela i ka laulā o -40 ℃ a + 80 ℃, me ka ʻole o ka ʻelemakule, ʻaʻole ia e haki, no laila hiki ke hoʻohana ʻia i nā wahi paʻakikī e like me nā wahi anu.
