Ke koʻikoʻi o ka ASTM A252 Round Seamless Carbon Steel Pipe a me Tube no ka Piling

He hilinaʻi loa kā mākou mau paipu kila, paʻa a hāʻawi i ka waiwai nui no ke kālā. He paipu kila wili ʻole ʻo ASTM A252 no ke kaula ʻana. Hoʻokō ia me nā kūlana o ka 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 nā ASTM A252 Seamless Steel Tubes a me ERW Steel Tubes no nā noi piling, a ke hōʻoiaʻiʻo nei mākou e kūlike kā mākou huahana me nā ana hoʻomalu maikaʻi āpau e pono ai. Kūpaʻa kā mākou mau paipu kila i ka pala, e hōʻoiaʻiʻo ana e hiki iā lākou ke kū i nā kūlana kaiapuni ʻino, kahi e hoʻonui ai i ko lākou ola lawelawe.

ASTM A252PAPA 1 PAPA 2 PAPA 3 Nā kikoʻī no ka poepoepaipu kila kalapona humuhumua koi nā paipu i ke kaumaha o ka paipu ʻaʻole i ʻoi aku ma mua o 15% a i ʻole ka liʻiliʻi ma mua o 5% o ke kaumaha kumumanaʻo. Eia kekahi, ʻaʻole hiki ke loli ke anawaena o waho ma mua o + a i ʻole 1% o OD, a i ʻole ka liʻiliʻi ma mua o 12.5% ​​​​o ka mānoanoa o ka paia maʻamau. Ma lalo o kēia kikoʻī, penei nā pae lōʻihi:

Ka Lōʻihi Kaulike Hoʻokahi: 16 a 25 kapuaʻi
Ka Lōʻihi Kaulike Pālua: Ma luna o 25 kapuaʻi (mika)

ʻO kekahi o nā pono o ka hoʻohana ʻana i ka paipu kila kalapona seamless a Botop Steel no kāu mau pono pili ʻana, ʻo ia ka pono e lawe mai ai. He māmā loa kā mākou mau paipu kila a maʻalahi hoʻi e lawelawe, no laila hiki ke lawe maʻalahi ʻia mai kekahi wahi a i kekahi. He maʻalahi hoʻi ka hoʻopili ʻana a me ke kau ʻana i nā paipu i ka hohonu i makemake ʻia.

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