Advantage #2: Welded vs. Mechanical Joints for Rubber-Lined Pipe

Joint Lock Ring video demonstration

Welded joints have always been the standard connection method for unlined pipe due to their strength and ease of construction. Now with Joint Lock Ring™ technology, welded joints are available for rubber and polyurethane lined pipe as well.

Advantage #2 - Field Length Adjustments are a Breeze with Welded Joints

Field length adjustments for lined pipe with mechanical joints can add days or weeks to a project schedule. Bends and critical junctures often require waiting for a pipe fitting fabricated to a specific length and lined at a shop. Joint Lock Rings™ can easily be installed on field fit-up ends and are ready to weld within hours. Also, long radius field bends can be accomplished just like unlined pipe.

Flanged Joints

Mechanical joints significantly complicate the construction process.

Welded Joints
