Stainless steel flanges

Stainless steel flanges are used to make connections in pipeline systems. They are connected with bolts, which enables easy maintenance, repair or replacement of pipeline parts. Van Leeuwen supplies stainless steel flanges in many different types, dimensions, pressure classes and gaskets. It depends on the application of the pipeline to determine which flange is suitable.
