Product Description

Weld Neck Flanges

We have emerged as the leading the exporter and importer of Weld Neck Flanges that are widely used in construction industry and plumbing field to be applied in pipes and process plant. It comprises a circular fitting along-with a protruding rim around the surrounding area. The flanges are machined with forging and are generally butt welded to a pipe. The rim embedded in flange has a series of drilled holes that help it to get fixed to another flange with bolts. Our Weld Neck Flanges are absolutely suitable for hostile environments that have extreme temperature, pressure or any other medium of stress.
