Threaded Flange

Threaded Flanges are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges' pressure applications.

Introduction

Our threaded flange is an economical and time-saving device used in different industrial applications. It can be assembled to the pipe without welding, making it suitable for use in extremely high pressure services at atmospheric temperature, and in highly explosive areas where welding is hazardous. The bore is threaded to match an external thread on the pipe.   TH flange is available in different sizes and materials to suit your unique requirements.
