What Certifications and Standards Should Steel Pipe Joints and Fittings Meet (ASTM/ASME/FM/UL) for Compliance?

ASTM A197 and ASME B16.3 are the two key standards that set the rules for malleable iron pipe fittings. They spell out everything from the material makeup and manufacturing steps to pressure rating requirements. The point of these standards is simple: making sure the fittings can safely take on Class 150 pressure, and keep their structural integrity solid no matter what operating conditions they’re under.

ASTM/ASME Standards - The Foundation

ASTM A197 and ASME B16.3 are the key standards regulating malleable iron pipe fittings. They lay out critical requirements: things like material makeup, manufacturing procedures, and pressure endurance ratings. When fittings comply with these guidelines, they don’t just meet the safe operating demands for Class 150 pressure—they also hold onto reliable structural stability, no matter the service conditions.

FM/UL Certification - Fire Safety Essential

For fire protection systems, FM and UL certifications are mandatory. These verify that galvanized malleable iron pipe fittings meet strict performance requirements for sprinkler systems and fire protection networks. Our products undergo rigorous testing to maintain these crucial safety certifications.

Regional Compliance Requirements

Different markets demand specific certifications:

▶ ABNT standards for Brazilian projects

▶ CE marking for European Union compliance

▶ TSE certification for Turkish markets

Our black malleable iron pipe fittings carry these regional approvals, ensuring global project compliance.

Quality Management - ISO Certification

ISO 9001 certification demonstrates consistent manufacturing quality and reliable production processes. This ensures every batch of malleable iron pipe fittings maintains the same high standards and performance characteristics.
