Preguntas frecuentes

  • Generally not recommended; threaded joints may loosen due to expansion. Welding flanges (e.g., DIN 2633) are better for high-temperature service.
  • Partially. Dimensions may align, but connection type and marking standards differ.
  • Normally ISO metric or BSPT threads depending on the application and regional practices.
