Ka mea nui o ka ASTM A252 Round Seamless Carbon Steel Pipe and Tube for Piling

ʻO kā mākou paipu kila he hilinaʻi loa, kūpaʻa a hāʻawi i ka waiwai nui no ke kālā.ʻO ASTM A252 kahi paipu kila ʻole i hoʻopaʻa ʻia no ka hoʻopili ʻana.Hoʻopili ia me nā kūlana American Society for Testing and Materials (ASTM) a loaʻa i nā papa like ʻole - Papa 1, 2 a me 3, me nā noi like ʻole.

Ma Botop Steel, hāʻawi mākou i kahi ākea o ASTM A252 Seamless Steel Tubes a me ERW Steel Tubes no ka hoʻopili ʻana i nā noi, a ke hōʻoia nei mākou i kā mākou huahana e hoʻokō i nā mea āpau e pono ai.Kūleʻa kā mākou paipu kila i ka corrosion, e hōʻoiaʻiʻo ana e hiki iā lākou ke kū i nā kūlana kūlohelohe koʻikoʻi, ka mea e hoʻonui ai i ko lākou ola lawelawe.

ASTM A252GRADE 1 GRADE 2 GRADE 3 Nā kikoʻī no ka punipaipu kila kalapona ʻolea koi ʻia ka paona o ka paipu ma mua o 15% a i ʻole emi iho ma mua o 5% o ke kaumaha kumu.Eia kekahi, ʻaʻole hiki ke hoʻololi ʻia ke anawaena o waho ma mua o + a i ʻole 1% o OD, a i ʻole ma lalo o 12.5% ​​​​o ka mānoanoa o ka pā.Ma lalo o kēia kikoʻī, ʻo nā pae lōʻihi penei:

Ka lōʻihi o ka lōʻihi: 16 a 25 kapuaʻi
Ka lōʻihi o ʻelua: ʻoi aku ma mua o 25 kapuaʻi (mika)

ʻO kekahi o nā mea maikaʻi o ka hoʻohana ʻana i ka paipu kalapona kila ʻole o Botop Steel no kāu mau pono piling ʻo ia ka maikaʻi e lawe mai ai.ʻO kā mākou mau paipu kila he māmā a maʻalahi hoʻi e mālama, no laila hiki ke lawe maʻalahi iā lākou mai kahi wahi ai kekahi.He maʻalahi hoʻi ka hoʻopili ʻana a hoʻokomo ʻia i ka hohonu i makemake ʻia.

I ka hopena, inā ʻoe e ʻimi nei i ka maikaʻi maikaʻi loa ASTM A252 GRADE 1 GRADE 2 GRADE 3 Round Seamless Carbon Steel Pipes a me Pipes no kāu koi ʻana, a laila ʻo Botop Steel ka wahi e pono ai.Pono kāu papahana kūkulu i ka maikaʻi loa, a ke kūpaʻa nei mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe loa e hōʻoia i ka ʻoluʻolu loa.E kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou huahana kila a me nā lawelawe.
