ʻO Botop Steel ka mea hana nui a me ka mea mālama i nā paipu kila a me nā paipu ma Kina, ke kūʻai aku nei mākou a hāʻawi i ka circular seamless carbon steel pipe no ka wai a me ka aila noi i ka nui o 10 OD a 660 OD i ka mānoanoa o 1mm a 100mm.Hana mākou i nā paipu kila LSAW carbon e like me ke kūlana honua e like me ASTM, API & DIN.Loaʻa iā mākou ʻoi aku ma mua o 8000 tons seamless line paipu i ke kumukūʻai i kēlā me kēia mahina, maʻamau hiki iā mākou ke hāʻawi koke i nā ukana.Eia nō naʻe ma nā hihia kūikawā, inā he waiwai opaipu kila kalaponaʻAʻole i loaʻa hiki iā mākou ke hāʻawi i nā ukana me ka manawa pōkole loa ma o nā kumu wili kūloko a i ʻole ka lawe ʻana mai
ʻO kā mākou a paupaipu kilaa ua hoʻolako ʻia nā huahana tube me 3.1 mau palapala hōʻoia kikoʻī, e like me EN 10204. Hiki ke ʻae ʻia ka palapala hōʻoia e like me 3.2 i ka manawa o ke kauoha.Ua ʻae ʻia ka nānā ʻana o nā ʻaoʻao ʻekolu (BV, SGS, etc.)
He helu kūpono o nā hemahema ʻike maka i
hāʻawi i ka hōʻoia ʻana i ka wā pono.
E wehe ʻia a ʻoki ʻia ka hemahema i loko o ka
