Shanxi Xinshunda Flange Manufacturing Co., Ltd. supplies high-precision EN1092-1 Type 13 hubbed threaded flanges engineered for medium-pressure piping systems requiring strong structure and non-welded installation. Fully compliant with EN1092-1, our Type 13 flanges combine the strength of a hubbed design with the convenience of threaded connection, ensuring stable sealing, high pressure resistance and long service life. With 19 years of forging and machining expertise, we provide reliable flange solutions to 3,800+ clients in over 70 countries worldwide.

Product Description

EN1092-1 Type 13 hubbed threaded flange is an integrated design with a reinforced hub and internal pipe threads. It combines high structural strength with threaded connection, eliminating welding while improving stress distribution and pressure bearing capacity. It is widely used in small-bore, non-weldable, hazardous, frequent maintenance or instrument piping systems. Our Type 13 flanges are precisely forged and CNC machined to ensure accurate thread fit, stable sealing and zero leakage under rated operating conditions.
