Perbedaan antara dua standar pengelasan

Thread Content

Mohon penjelasan mengenai perbedaan antara standar pengelasan HG/T20583 dan JB/T4709. Hari ini, saat merancang tangki penyimpanan bertekanan normal, saya menemui dua standar ini. Mohon beri penjelasan mengenai perbedaan kedua standar tersebut

JB/T4709 telah digantikan oleh NB/T47015. 。 Coba bandingkan sendiri, fokus standarnya berbeda-beda: HG/T20583 untuk desain struktur wadah kimia, NB/T47015 untuk prosedur pengelasan wadah bertekanan

Satu adalah desain, satunya lagi adalah proses pembuatan
