Inā hoʻoheheʻe ʻia ka paipu kila AS 1074, pono ia e kūlike me AS 1650.
Pono ka ʻili o ka paipu galvanized e hoʻomau ʻia, e laumania a puʻunaue like ʻia e like me ka hiki, a ʻaʻohe hemahema e hoʻopilikia ai i ka hoʻohana ʻana.
Pono e hoʻoheheʻe ʻia nā paipu me nā kaula ma mua o ke kau ʻana i ke kaula.
E hoʻokaʻawale ʻia nā paipu e ke kala ma kekahi wēlau penei:
| ʻŌmole | Waihoʻoluʻu |
| Paipu kukui | Palaunu |
| Paipu waena | Polū |
| Paipu kaumaha | ʻulaʻula |
He mea hana a mea hoʻolako paipu kila kalapona kiʻekiʻe mākou mai Kina mai, a he mea kūʻai aku paipu kila seamless hoʻi, e hāʻawi ana iā ʻoe i kahi ākea o nā hoʻonā paipu kila!
