Rincian produk
baja karbon Tabung
,Penukar panas tabung
ASTM A214 SA214 ERW Karbon Baja Pipa Penukar Panas Pipa Kondensator
Jangkauan ukuran:O.D.:6-76.mm W.T.:0.9-19.0mm L: sesuai kebutuhan pelanggan
Pembuatan:
Tabung dibuat dengan pengelasan resistensi listrik.
Kelas baja dan komposisi kimia:
| C | 0.18 |
| Mn | 0.27 ke 0.63 |
| P | ≤ 0.035 |
| S | ≤ 0.035 |
Persyaratan kekerasan:
Tabung harus memiliki nomor kekerasan tidak lebih dari 72HRB.
Kondisi permukaan:
Tabung yang sudah jadi bebas dari skala., sedikit oksidasi tidak dianggap sebagai skala
Pengolahan panas:
Setelah pengelasan, semua tabung dirawat panas pada suhu 1200 °F ((650 °C) atau lebih tinggi dan selanjutnya dengan pendinginan di udara atau di ruang pendinginan di tungku atmosfer terkontrol.
Tabung-tabung yang ditarik dingin harus dirawat panas setelah melewati proses penarik dingin terakhir pada suhu 1200°F ((650°C) atau lebih tinggi
Uji dan Pemeriksaan:
Persyaratan Kekerasan
Tes Mekanis
- Tes perataan
- Uji Flange
- Uji terbalik
- Uji listrik hidrostatik atau tidak merusak
