Threaded Flange

Threaded Flange

Threaded Flange
Threaded flange (Screwed flange) is similar to the Slip-On flange, but is popular because it can be attached without welding since it is designed with tapered threads to work with pipes that have external threads. Also low cost, it’s great for small pipes and highly combustible areas where welding is dangerous.
