Product Introduction

Large diameter flat welding flange connections are easy to use and can withstand high pressure, playing an important role and value in use Large flange connections are widely used in industrial pipelines and have different meanings and functions in industry In the home, the diameter of the pipeline is small and it is low-pressure, so flange connections cannot be seen If there are large flange connected pipelines and equipment everywhere in a boiler room or production site There are two production processes: forging and rolling
