Paipu wiliwili (SSAW)pili nui ka hale hana i ka nalowale o ka paipu spiral. Mai ka pā kila a hiki i ka helu huahana i hoʻopau ʻia o ka paipu spiral, ʻo ka nui o ka nalowale o ka mea hana paipu spiral i ka wā wili e pili pono ana i ke kumu kūʻai o ka paipu spiral.

ʻO ke kumu no ka helu ʻana i ka hua o ka paipu spiral:
b=Q/G*100

ʻO b ka helu huahana i pau, %; ʻO Q ke kaumaha o nā huahana kūpono, i nā tona; ʻO G ke kaumaha o nā mea maka ma nā tona.

Loaʻa i ka hua ka pilina pili me ka coefficient hoʻohana metala K.

b=(GW)/G*100=1/K

ʻO ke kumu nui e pili ana i ka huahana waiwai ʻo ia nā poho metala like ʻole i hana ʻia i ka wā o ke kaʻina hana. No laila, ʻo ke ʻano o ka hoʻomaikaʻi ʻana i ka huahana waiwai ka mea nui e hōʻemi i nā poho metala like ʻole.

No ka mea, ʻokoʻa nā mea maka i hoʻohana ʻia i loko o kēlā me kēia hale hana wili kila mai nā huahana i ʻōwili ʻia, no ka laʻana, hoʻohana kekahi mau hale hana kila kila e like me nā mea maka, wehe ʻia nā blanks ma waena, a ʻōwili iā lākou i mau mea; hoʻohana pono kekahi mau hale hana i nā mea kila e like me nā mea maka a ʻōwili iā lākou i mau mea; Hoʻohana ʻia nā billet kila e like me nā mea maka e ʻōwili i nā mea; aia kekahi mau hale hana e hoʻohana ana i ke kila ma ke ʻano he mea maka no ka hana ʻana i nā huahana kila like ʻole. No laila, paʻakikī ka hoʻohana ʻana i kahi ʻano helu hua e hōʻike a hoʻohālikelike i ke kūlana ohi metala i ke kaʻina hana, a paʻakikī hoʻi e noʻonoʻo i nā ʻokoʻa o ka pae ʻenehana hana a me ka pae hoʻokele o ka hale hana. Ua ʻōlelo ʻo HSCO spiral pipe factory aia nā ʻano ʻano like ʻole no ka helu ʻana i ka hua, e like me ka hua o nā mea kila, ka hua o nā mea kila, a me ka hua o nā billet haole. Pono e helu ʻia kēlā me kēia hale kūʻai wili e like me ke kūlana kikoʻī.

Ka helu ʻana i ka nui o ka pohō o ka paipu spiral:

ʻO ka nui o ka pohō ʻana o ka paipu spiral e pili ana i ka lākiō ʻōpala o nā mea maka i loko o ke kaʻina hana paipu spiral. Wahi a ka helu helu helu o nā limahana a me nā limahana loea no nā makahiki he nui, ʻo ka nui o ka pohō o ka hana paipu spiral ma waena o 2% a me 3%.
ma waena. I loko o ke kaʻina hana ʻo spiral tube, ʻo nā mea nui o ka ʻōpala: ʻo ka ʻaoʻao mua o ka paipu spiral i hana ʻia, ka huelo, ka wili wili o ka mea maka, a me nā ʻanuʻu e pono ai i ke kaʻina hana ʻo spiral tube. Inā ʻaʻole hiki ke wili ʻia ka paipu spiral e like me nā kūlana maʻamau i ka wā o ke kaʻina hana, ʻo ka paipu kila i hana ʻia he haʻahaʻa haʻahaʻa loa.

Pehea e hoomalu ai i ka poho o ka paipu spiral?
1. Ma hope o ka hoʻokumuʻiaʻana o ka paipu kila spiral, pono eʻokiʻoki i ka'āpana mua a wehe i ka huelo e pale i ka pololeiʻole o ka paipu kila. He hana koʻikoʻi kēia e hōʻoia i ka kikoʻī a me ke ʻano o nā paipu kila, a e hana ʻia ka ʻōpala i kēia kaʻina hana.

2. No ka hana ʻana i nā mea maka, pono e wili ʻia ke kila kila a me nā hana ʻē aʻe ma mua o ke kuʻi ʻana. Ma kēia kaʻina hana, e hana pū ʻia nā mea ʻōpala.
