Forged flanges are manufactured by closed-die forging, which aligns the grain flow of the metal to the shape of the flange — resulting in superior mechanical strength, toughness, and fatigue resistance compared to cast or plate flanges. We supply forged flanges in the following materials and grades for projects across Africa, USA, Mexico, Oman, and Europe:
All forged flanges we supply are accompanied by Material Test Certificates (MTC to EN 10204 3.1) confirming the exact grade, mechanical properties, and heat number — ensuring full traceability and compliance with international project specifications. PMI testing is available on request.

Correct forged flange selection is critical to ensuring a leak-free piping system and long-term operational safety. The flange type, material grade, and pressure class must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing a forged flange for projects in Africa, USA, Mexico, Oman, or Europe:
