Nā paipu kila humuhumu no ka hana ʻeli lanahu - GB/T 17396-2009 Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

ʻO ka paipu kila humuhumu no ka lua lanahu e hoʻohana nui ʻia e hana i ka paipu humuhumu no

mea hoʻoikaika hydraulic i loko o ka lua lanahu.

Uku:30% waiho, 70% L/C a i ʻole B/L kope a i ʻole 100% L/C i ka ʻike ʻana

Ka nui o ke kauoha liʻiliʻi loa:25 T

Ka hiki ke hoʻolako:Ka Papa Hana Makahiki 20000 Tons o ka Paipu Kila

Ka manawa o waena o ka hoʻomaka a i ka wā pau:7-14 mau lā inā ma ka waihona, 30-45 mau lā e hana ai

Hoʻopili ʻana:ʻEleʻele Nalowale, bevel a me ka pāpale no kēlā me kēia paipu; Pono e hoʻopaʻa ʻia ka OD ma lalo o 219mm i loko o ka pūʻolo, a ʻaʻole ʻoi aku kēlā me kēia pūʻolo ma mua o 2 tons.
