Description

Threaded / Screwed flanges are designed to connect flanges and pipes by means of threads. It means that the male threads of the pipe are screwed into the female threads of the flange to complete the connection of the piping process. Threaded flanges are suitable for low pressure and temperature applications.

Founded in 2000, Zhongnuo focus on the manufacture of forged flanges, including carbon steel flanges and stainless steel flanges. The flanges we supply have perfect appearance, accurate dimensions, excellent performance, and durable in use. We are also an ISO certified flange manufacturer, which can meet the demanding quality requirements of our customers’. Thanks to our strict quality control and professional services, it enables us to maintain mutual benefit cooperation with our customers.
