  Threaded flanges look very similar to Slip-On flanges but the main difference is that thethreaded flange has been was bored out to match a specific pipe inside diameter. The backside of this center opening is then threaded with the relevant-sized tapered pipe thread.

  Threaded Flanges can be used in very high pressure services and their major advantage is that they can be assembled without welding.

  We have adopted advanced production equipment and technologies to manufacture our weld neck socket flanges,threaded flanges
