Dureza:
Para los tubos que WT ≥2 mm, se deben realizar pruebas de dureza Rockwell.
Pruebas de los tubos de caldera sin soldadura:
Prueba 1.Bending:
Los tubos deben realizar la prueba de flexión cuando OD ≤22mm. El ángulo de flexión es de 90 grados, y el radio de flexión es 6 veces el diámetro exterior del tubo de acero.
2. Prueba hidráulica;
Pruebas de corrientes de Foucault, se pueden usar pruebas ultrasónicas en lugar de pruebas hidráulicas. Cuando las pruebas de corrientes de Foucault, GB / T 7735-1995 Gr. A debe seguirse; cuando las pruebas de ultrasonidos, GB / T 5777-1996 Gr. C8 debe ser seguido.
3. Prueba de aplanamiento.
4. Ensayo de bridas
5. Expandir la prueba
