1. Ringkesan Standar
Standar iki nyakup tabung baja tanpa sambungan kanggo boiler lan pipa uap, kalebu tabung sing ditarik adhem, digulung panas, dipres panas, lan dikurangi ukurane. Dimensi: tabung digulung panas OD 25-530 mm, kekandelan tembok 2,5-90 mm; tabung sing ditarik adhem OD 25-108 mm, kekandelan tembok 2,0-25 mm. Dawane: acak 3-12 m (digulung panas 4-12 m), dawa tetep miturut kabutuhan. Toleransi: OD +-0,25 mm nganti +-1,25%, kekandelan tembok +-8% nganti +20%/-5% gumantung saka ukurane. Kelurusan: 1,5-4,0 mm saben meter adhedhasar kekandelan tembok.

5. Syarat Inspeksi
Wajib 100%: pamriksan dimensi, inspeksi permukaan, uji ultrasonik (kanggo cacat longitudinal), lan uji hidrostatik. Sampling saben batch: analisis kimia (3 potongan saben panas), tarik suhu ruangan (2%), dampak (2%), kekerasan, lan uji proses (pembakaran, perataan, pembengkokan). Tes tambahan miturut panyuwunan pelanggan: tarik suhu dhuwur, kekuatan pecah mumbul, korosi intergranular (kanggo stainless steel), ultrasonik transversal, lsp.

7. Cathetan Penting
Standar TU iki luwih ketat tinimbang GOST lan dirancang khusus kanggo aplikasi boiler superkritis lan ultra-superkritis.
Telung kelas inti tahan panas yaiku 12Kh1MF (570-585 C), 15Kh1M1F (<=585 C), lan 12Kh2MFSR (<=620 C).
10Kh9MFB-Sh kira-kira padha karo P91, nanging komposisi lan rincian pamriksan beda; priksa manawa sampeyan wis mriksa sadurunge ngganti.
Pengujian ultrasonik 100% iku wajib, nggunakake sampel referensi standar (SOP) kanggo evaluasi cacat.
Ing antarane kelas austenitik, 12Kh18N12T nawakake resistensi suhu paling dhuwur (nganti 800 C kanggo layanan pipa jangka pendek).
