Hoʻopiha hou ʻana i ke kauoha ʻenekinia, paipu kila metala huahanaA333 GR6, ʻo ke kikoʻī he 168.3*7.11, apaipu kila kalapona GB/T9948, 20#, ʻo ke kikoʻī he 114.3*6.02, a pēlā aku.

Eia ka mea e hōʻike ana i nā kūlana a me nā mea e kū ai nā kauoha ʻenekinia:

20 # GB8163 paipu kila humuhumu halihali wai

He aha ke ʻano o ka mea paipu kila seamless? ʻO ka mea hoʻi ke ʻano a mākou e ʻōlelo pinepine ai, e like me 20#, 45#, e hōʻike ana i kona ʻano kemika a me nā waiwai mechanical e like me ka ikaika tensile, ka ikaika yield, a me ka wikiwiki o ka hoʻonui ʻana. Eia nā mea paipu kila seamless i hoʻohana pinepine ʻia, nā kūlana hana a me nā hoʻohana i hōʻuluʻulu ʻia e ka mea kākau.
