1. Loaʻa ʻole (lōʻihi maʻamau)
ʻOkoʻa ka lōʻihi o ka lōʻihi o ka lōʻihi o ka lōʻihi i kapa ʻia ʻo ka lōʻihi ʻole i loko o ke ʻano o ka maʻamau. Ua kapa ʻia ka lōʻihi ʻole ka lōʻihi maʻamau (ma o ka lula). No ka laʻana, ka lōʻihi o 159*4.5paipu kila maʻemaʻe ʻoleʻo ka maʻamau he 8~12.5

2. Paʻa ka lōʻihi
ʻOki i ka nui paʻa e like me nā koi kauoha i kapa ʻia ka lōʻihi paʻa. I ka hāʻawi ʻana e like me ka lōʻihi paʻa paʻa, pono i ka galvanized seamless steel pipe ka lōʻihi i ʻōlelo ʻia e ka mea kūʻai aku ma ka ʻaelike kauoha. No ka laʻana, inā ʻōlelo ka ʻaelike e hoʻokumu ʻia ka lawe ʻana ma kahi lōʻihi paʻa o 6m, pono nā mea i hāʻawi ʻia he 6m ka lōʻihi. ʻAʻole kūpono nā mea i ʻoi aku ma mua o 6m a ʻoi aku paha ma mua o 6m. Akā ʻo ka ʻoiaʻiʻo, ʻaʻole hiki i ka hāʻawi ʻana ke 6m ka lōʻihi, no laila ua ʻōlelo ʻia e ʻae ʻia kahi haʻahaʻa maikaʻi, akā ʻaʻole ʻae ʻia ka ʻae ʻole. (Ke emi ka lōʻihi ma mua o 6m, e hoʻonui ʻia ka ʻae ʻia i +30mm; inā ʻoi aku ka lōʻihi o ka lōʻihi ma mua o 6m, hoʻonui ʻia ka ʻae ʻia i +50mm)

3. Manawa
ʻO ka nui paʻa i ʻoki ʻia i loko o nā ʻāpana integral e like me nā koi kauoha i kapa ʻia ʻo ruler pālua. I ka lawe ʻana i nā lōʻihi he nui, ʻo ka lōʻihi o ka paipu kila uʻi galvanized i hāʻawi ʻia he mau helu helu o ka lōʻihi (i kapa ʻia he lōʻihi hoʻokahi) i kuhikuhi ʻia ma ka ʻaelike kauoha e ka mea kūʻai aku (me ka ʻoki ʻoki). No ka laʻana, koi ka mea kūʻai aku i ka lōʻihi o 2m ka lōʻihi ma ka ʻaelike kauoha, a laila he 4m ka lōʻihi ke ʻoki ʻia i loko o ka lula pālua, a ʻo 6m ke ʻoki ʻia i loko o ka ruler triple, me hoʻokahi a ʻelua paha ʻoki. .
Hōʻike ʻia ka nui o ka ʻoki ʻoki i ka maʻamau. Ke hāʻawi ʻia ke aliʻi pālua, ʻae ʻia ka haʻalele maikaʻi wale nō, a ʻaʻole ʻae ʻia ka ʻae ʻole ʻana.

4. Luna pōkole
ʻO ka lōʻihi ka liʻiliʻi ma mua o ka palena haʻahaʻa o ka lōʻihi palena ʻole i kuhikuhi ʻia e ka maʻamau, akā ʻaʻole i emi iho ma mua o ka lōʻihi pōkole ʻae ʻia ua kapa ʻia ka lōʻihi pōkole. No ka laʻana, ʻo ka maʻamau o ka lawe ʻana i ka wai paipu kila e ʻae ʻia he 10% (helu ʻia e like me ka helu) o nā paipu kila pōkole me ka lōʻihi o 2-4m e ʻae ʻia i kēlā me kēia pūʻulu. ʻO 4m ka palena haʻahaʻa o ka lōʻihi ʻole, a ʻo ka lōʻihi pōkole loa i ʻae ʻia he 2m.
