He aha ke ʻano o ka mea paipu kila seamless? ʻO ka mea ka mea a mākou e kapa pinepine ai he papa, 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.
1.GB/T8162-2018, Nā paipu kila wili ʻole kūkulu, hoʻohana nui ʻia i ka ʻenekinia kūkulu maʻamau, ka hana mīkini, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe. Nā mea i hōʻike ʻia: 20#, 45#, q345b, 40Cr, 42CrMo, etc.;
